Samsung Ubigate iBG-1000 router

2021-12-21 Thread Cameron Kaiser via cctalk
Well, DSL Extreme is getting out of the T1 business, leaving me high and dry
(they've really gone to hell since GTT bought them out) since they don't offer
a static IP option on any of their lines anymore. I'll be working around that
problem for the next couple months while we move ...

Anyway, I have a spare Ubigate iBG-1000 T1 router here set up by the tech, but
no password to access it. It appears to be an embedded PowerPC system, around
603 level. I have some possible reset instructions and can access its serial
console, but was wondering if anyone out there has the administration manual
for it. It might be fun to repurpose it.

restoring a Silent 700 Model 765

2022-03-19 Thread Cameron Kaiser via cctalk
I found my old Model 745 in storage and other than needing a print head clean
and adjusting the printer contrast, it works splendidly. It has the manual and
I've got some plugs to build it an RS-232 connector when I find some more round
tuits.

This whetted my appetite for other 700s, including the (in)famous bubble memory
763/765. I was able to land a set of 765 ASRs. One of them came with Telenet
transcripts from The Source (various logins from 1978 to 1980), which was
really cool reading. I'll scan these.

However, neither of them work. Both power on, but they immediately go into
COMMAND mode and sit there, which appears to be abnormal behaviour based on
what I'm reading in the service manual (thanks, Bitsavers!). The NUM LOCK
switch works and the paper advance works, but nothing else appears to elicit a
response. One of them advances the page and acts like it's printing the command
prompt, but the other one doesn't even do that.

The service manual suggests I need to replace both the TMS 9980 and 8080
boards, which would really suck. I'm hopeful that the one that's "more active"
has a working 9980 board and I can use the 8080 board from the other one. (I
haven't even gotten to the bubble memory yet.) Anyone repaired these units or
have an idea of a repair strategy other than replace damn near everything?

I'm not sure if the prior owner was a writer or just an interested subscriber,

If we're going to do Tymnet, we should definitely do Telenet. I'll also throw
in SLIP, since I imagine most remote access nowadays is all PPP, and maybe even
old school EtherTalk or LocalTalk.

I had a T1 locally up until a couple months ago. I still have the smartjack and

Looking for Silent 700 Model 765 lower board

2022-05-07 Thread Cameron Kaiser via cctalk
These things must be cursed by G-d. I've landed three. Two had bad lower boards
(the ones with the bubble memory and the main 9980 MCU) already. The third had
a bad print mechanism. I replaced the printer mechanism, but the printhead on
that was bad, so I powered it down and replaced the print head. I power it back
up and its lower board suddenly stops responding too. Then, shortly after that,
the upper board! (What is that circular metal can bolted down with wires
exiting near the power switch? It squeals like a stuck pig.)

I have plenty of bubble memory boards from these damn units, but what I need is
 a working lower board itself. Unless someone is experienced with board level
repair and knows the typical faults on these.

I'm not even sure I'd call them related. The i960 is a very different, almost
"normal" RISC chip compared to the i860, though it uses Berkeley register
windows like SPARC. It has excellent XOR performance, so it got used a lot
later on in RAID arrays (my Apple Network Server 500 has a RAID card with an
i960 on it). A few systems used it and it was popular in military applications
but it never achieved its potential mostly due to internal politics at Intel --
not because it sucked -- and the DEC StrongARM settlement mostly put a stake

Bubble memory uses magnetic domains, so to a first approximation it's as
"stable" as any other magnetic storage system. These domains tend to be
relatively large by modern standards. The modules are invariably magnetically
shielded in heavy coverings, and are shockproof. If it works it all, it
probably works fine.

I have a Texas Instruments Silent 700 Model 763 and so far no problems with
storing and retrieving data on its bubble memory cards, even though this unit
is well over 40 years old (here it is with my KIM-1 as a punch tape storage 
system:


http://oldvcr.blogspot.com/2022/09/what-kim-1-really-needs-is-bubble.html

).

There are no modern drop-in equivalents for bubble memory modules specifically.
Bubble memory is inherently serial and requires additional drive circuitry.
However, that doesn't mean someone couldn't make a unit that emulates the
entire system and looks like a bubble memory storage device, naturally, just
like any other disk emulator.

[cctalk] RDI BriteLite IPX keeps going to white screen

2022-10-29 Thread Cameron Kaiser via cctalk
I've been trying to do a little work on the RDI BriteLite IPX I have here, but
when it runs more than a few minutes the LCD just blanks out white. The machine
seems to still respond to commands, so it seems like it's something with the
display hardware. Even powered off and back on it won't go back to normal until
I let it sit for awhile.

I suspect heat is part of the issue and it certainly feels warm; there are two
loud cooling fans inside, but with the case off and checking airflow the fans
do seem to be working. Having the case off doesn't make the display any happier
though. One fan is in the power supply and another fan is in the (LCD?)
inverter board. Finger-checking large chips while in operation doesn't burn the
skin.

Anyone familiar with this issue? I suppose I could look for a SPARCstation IPX
to take the motherboard out of and replace this one with it, but it seems more
like the problem is in the display, which is a custom part.

That's an interesting thought. It's almost certainly an IC, though I don't know

RDI-custom). I suppose I could start with what's in the cooling airflow zone.

There are brightness and contrast controls, but they don't seem to do anything

controller.) Likewise, when the screen goes white, turning down the brightness

suddenly went out. Colours show and match what should be on screen but the
horizontal display is scrambled. It does it on both Peanuts, so I think
something in the display blew.

Anyone recognize this issue? Seems like it should be a straightforward fix; I
can't imagine this monitor is particularly complex internally.

A good suggestion. This morning it powers up fine, so maybe there's a cold or

[cctalk] GLACIER-01 in the DataRover 840

2022-11-10 Thread Cameron Kaiser via cctalk
Cracked open my General Magic DataRover 840 to find out what specific MIPS
R3000 variant is in it. However, the only chips that are large enough to be
CPUs are *two* with Bowser logos marked (C)GMI JAPAN GLACIER-01 F840276. The
other chips of notable size are easily identified as RAM, a sound/modem codec
and the inverter for the LCD backlight.

I've seen systems with two CPUs that handle two halves of an LCD (the Tandy

I second the Arduino recommendation. I have a Power Mac G4 with a serial dongle
that drives an Arduino Nano-based IR blaster. It sends serial commands to it
and the blaster transmits a signal to the room air conditioner. Should be easy
to adapt the GPIO pins to a relay. Arduino programming and interfacing is
pretty straightforward.

[cctalk] Apple AWACS register documentation

2022-11-17 Thread Cameron Kaiser via cctalk
Any Apple alumni (Al?) with documentation on AWACS registers? I'm trying to
figure out why the BeOS AWACS sound driver works on some Power Mac 6500s and
TAMs but not others (but works fine on 6400s and everything previously).

Yes, I'm aware that Be considered the 6500 "Unsupported but Compatible" and it
boots fine on my 6500/275 but is totally mute. An instrumented driver in debug
mode yielded little insight. The driver thinks it's initialized everything
correctly and reports no errors. I wonder if there's something about the SRS
sound enhancement that's different on later 6500s/TAMs.

I worked with an elementary school teacher who used exactly such a system to

the dial to each client in turn and ran CLOAD on the client, and it pulled it
over the cassette port. No automatic push, but I think he had only around 15

I don't think it's the connector, but it's junk if it isn't anyway, so I might
see. These things screw in place and the fit was tight getting it out so it
would boot again, so I don't think it wiggled. Still, would be nice to know a

I think that's possible, but it would need someone with better soldering skills

Yes, though not exactly. The TI implementation was a true, full Micro-TUTOR

(By the way, I had a typo in my message: it's the upper *six* bits, not five.)

I thought about this, but the KIM is a pretty simple system. The only memory
mapped device in that range (really, on the entire unit) are the RIOTs, and
their RAM at $1780 is fine and does not echo.

The KIM only does address decoding for 8K and echoes the rest, so the same
fault is mapped at $2280, $4280, etc. I would think this would still suggest
data is the problem.

I suppose I could randomly replace the RAM and see what changes but again it
seems weird to have a fault so neatly aligned and only in a specific range.

With a simple step through program,

*=$
r=$0280

inc w
lda w
sta $f9
sta r
sta r+1
lda r
sta $fb
lda r+1
sta $fa

cmp #$12
bne *-8

jsr $1f1f
jsr $1f6a
cmp #$15
bne *-5

jmp $

w   .byt 0

it's actually an artifact of the monitor that the upper 6 were clear. Actually,
the stuck bit is entirely bit 2 (i.e., it goes

0 1 2 3 4 5 6 7 8 9 a b c d e f
0 1 2 3 0 1 2 3 8 9 a b 8 9 a b

and the high nybble is OK). Now that sounds more like a bad RAM chip, but why
would it be *just* those addresses? Does that sound like a plausible failure 
mode?

No, what I mean is, the appearance of the upper six bits being dead was because
of how the monitor shifts in data from the keypad. Since bit 2 was always zero,
it would look like everything above it was zero too because the bit shifts
carried the error forward. A direct brute-force step through showed the actual
issue and I should have just done that in the first place. The monitor works
properly everywhere else outside of those locations, including from the TTY.

Interesting. I guess it could be any of the E-class, though: OpenPA has a
picture of an E35 that looks like a slightly closer match. I'm surprised
it's recent enough to have a PA-7100; I would have agreed with Zane that it
was an earlier type system.

I can't answer the cell count, but I can give a general answer on the rest.

Mercury interferes with multiple enzymatic processes -- some of them
permanently -- and it can be slow to metabolize (half life of approximately
two months), meaning even a small dose can destroy a lot of cells. The central
nervous system is at greatest risk because these enzymes frequently repair
oxidative damage from metabolic processes, and nerve cells have high rates of
metabolism for processing.

As mentioned, mercury compounds are often far more toxic than the pure form.
Dimethylmercury is especially effective because the extra methyl groups enable
it to very easily enter the body and pass through cell membranes but
only very slowly be eliminated from it; some metabolites can actually bind
to tissues and remain. In this case, as little as 0.1mL is enough to cause
severe or fatal poisoning according to the OSHA bulletins I have here because
it will enter cells and accumulate there. Once it reaches the central
nervous system, that's it. The NEJM article on the Wetterhahn case (read:

http://www.nejm.org/doi/full/10.1056/NEJM199806043382305

) estimates a lethal dose of the compound would be about 5mg/kg body weight.

(As an aside, though, mercury-containing antiseptics such as thiomersal
"Merthiolate" and merbromin can be safe and effective sterilizers in very
low concentrations. They work through the oligodynamic effect. I grew up
with my mother wielding the Mercurochrome whenever I'd get a cut, and I think
it was unfairly removed from the market -- not due to toxicity, but because
it was a generic product with no profit potential, so the pharmas wouldn't
do the studies and the FDA classified it as "non-GRAS" along with a number 
of other orphaned compounds in 1998. It is still very common outside the US.)

In the Wetterhahn case, latex and PVC gloves are also easily penetrated by
the compound (including those she was wearing), affording her no protection
at all when it spilled on her and was able to pass through her skin into the
bloodstream. It is also possible part of her toxic dose came from vapour,
although the fume hood should have reduced this. By the time her symptoms
indicated that she had indeed received a toxic dose, chelation therapy would
have been ineffective, as it indeed was. The estimated total dose per the
NEJM article was about 1.3g of mercury, over three times the lethal amount.

Don't mess with it.

This isn't quite true. Elemental liquid mercury will pass through skin but

For the OP, having the hardware still (last I checked) entitles you
to run AIX on it. You just have to find the media, which for a system that
old is not easy. I've never been able to find 4.1.5 on CD, for example,
even though I know it exists. (I have 4.1.5 for my Apple Network Server on

Seven years ago I couldn't get IBM to take my money when I was ready to buy a
brand new POWER7 to take over for my dear ANS 500 (which will be at VCF in
August, btw). I had my credit card and a $14,000 budget. I was ready to buy.
I couldn't get them on the phone. I couldn't get *half their VARs* to return
a call.

I ended up buying a used POWER6, about $10K all told, from a reseller who
*was*, in fact, happy to take my money. So I do business with them. It
runs AIX 6 TLmumble with some patches. It is the machine sending you this
E-mail.

I suspect the issue is IBM doesn't want to do business with people like me
who can maintain our own hardware. Power Systems are hardly commodity x86
servers, but the real money is in service contracts, and that was the one
thing I was not going to pay for.

Never did hear back from them.

It's kind of both. I don't think George routinely distributed VAX binaries
for MOSAIC, but if he said it would build on VAX, I believe him. The support
probably falls somewhere between Navigator 3 and 4, most likely (better
HTML4 support but virtually no scripting). He and I chatted a little since
I was looking at borrowing some of his code for CK-Mosaic.

George's old site on WVNET doesn't seem to be up anymore. :(

> I'd be more than happy to buy it, do you think settling for 4.1.4 when it

The main difference (having run both) is that 4.1.4 has a very nasty leak
in the sockets code. My production ANS 500 would run out of memory after
awhile because of all the sockets it opened and closed. 4.1.5 fixed this bug
and others.

Also, a lot of software that is 4.1-compatible requires 4.1.5 at minimum,
such as the few AIX games that are floating around. (I was recently able
to coerce my 500 into playing Quake and Abuse, but only because it has
4.1.5 and I happen to have an Ultimedia option CD.)

For that reason, while I appreciate Glen's offer, I really do need a 4.1.5
on CD; 4.1.4 won't do for my purposes.

But if you just want to mess around with AIX, 4.1.4 is perfectly cromulent.

Depends on what you want to run on it. AIX 5 definitely had poorer multimedia

OTOH, AIX 5 is certainly a lot easier to find, and works well enough at the

I just cheat and use a straight through DB-15 (waiting for someone to tell me
it's a DQ-15 or something instead ;), like a PC joystick cable or some such.

Duly noted for the one I have here, but it runs Venix/PRO. Gotta try 2.9BSD one
of these days.

[cctalk] KIM-1 debug board RAM test: *zero* flashes

2023-07-03 Thread Cameron Kaiser via cctalk
I assembled Dwight Elvey's KIM-1 debug board (thank you, Gary!) and have now
certified two of my KIMs with it, so I'm very confident the harness operates
properly.

Unfortunately, the one I *want* to repair, my original KIM-1, won't start up at
all after replacing the 2102 RAM I was pretty sure was bad. I checked my
soldering and found a couple spots without continuity that should according to
the schematic, but fixing those didn't fix it. I also buzzed out the socket and
found no obvious shorts, and a second 2102 equivalent from a second
manufacturer has the same symptoms.

I connected the debug harness and test 0, the initial "dead board" test, does
show CPU accesses on the red LED and slowly flashes the green LED, so the CPU
at least is alive and can access the test EPROM.

However, test 1, the RAM test, should show long flashes of the green LED if RAM
is bad. I was prepared to see all long flashes which might implicate the
buffers or address decoder, but instead it won't blink the LED at all in that
or any of the other tests. The red LED remains lit and appropriately
extinguishes when the RS button is down.

Again, the board works correctly and fully certifies the other two KIMs.

What would cause it to hang (?) in the RAM test on the defective one?

Dwight suggested something wrong with the address lines. That made sense, since
the continuity problems I had on the board were on the address lines (turned
out to be lifted traces). However, after spending a couple hours more with the
tester, the actual problem was two address lines that had an intermittent
short. I cleaned that up and everything passes.

The original fault, a bad 2nd bit from $280 to $2bf, was indeed a single RAM
chip gone bad in a single row. Now that it's replaced and the board is fixed,
the fault is gone. Buffers and address decoding check out just fine.

[cctalk] 50 pins in three rows

2023-08-04 Thread Cameron Kaiser via cctalk
In a shipment today I got several AMP-labeled dongles that look like SCSI
terminators ... except the 50 pins are arranged in three rows (17-16-17), not
the Centronics-style 50-pin connector nor the usual 2-pin configuration.

Anyone seen those before, and is it actually SCSI, or is it something else?

Given what else was in there, this makes sense, and they look exactly like a
SCSI terminator should look. TIL. Thanks!

I have an IMSAI as well, but for me my favourite computer of that era is the
KIM-1, and that's such a simple design there are tons of reimplementations
(though I prefer the original since some of them apparently have edge-case
incompatibilities).

This week I installed a cooling fan in my Commodore 128DCR. I've been inside
that unit twice in the last couple months to replace the power supply and then
solder the leads and mount the fan. The warranty sticker remains undisturbed.

I just got out my own UltraBook IIi to test and while it makes a lot of

come up into OpenBoot and will start Solaris. I note that it states it seems to
have already lost its NVRAM contents but appears to have spontaneously

Maybe, but it also says

"Setting NVRAM parameters to default values."

which suggests it has default values stored somewhere to set NVRAM to. I don't
know much about these systems' boot process, however.
