Re: Wanted: stand for NeXT monitor

[Sean Caron]

It was always my experience ... I think NeXTstep had a reputation of being
a little balky on the proprietary NeXT hardware. I am fortunate to have a
decent swath of their product line ... an original '030 Cube, a Color slab
and a Turbo Color slab and even on the Turbo slab with 32 megs RAM and a
7200 RPM drive, NS 3.3 gets laggy.

Slow as it is, the entire package has certainly got some class and it's
something to revel at, of course.

Can you even run Openstep on the NeXT proprietary hardware? The performance
must be awful... I halfway thought NS 3.3 was the last revision they would
run ... 3.3 should be pretty common in the wild because NeXT was giving it
away for free with a valid NeXT serial number about 15 years ago as a Y2K
mitigation strategy :O I run 3.3 on all my NeXTs, even the '030 Cube.

If you really want to see NeXTstep 3.3 fly, people say it's great on the HP
9000/712 :O

Best,

Sean

I can second that. I recently bought a flock of them (for spares/parts for
the first one I bought), because they were so cheap on eBay - several I got
for $25 + shipping. Most of the ones I bought came without probes, etc, but I
managed to round up a very complete set of stuff without spending too much
money. Tek documentation is incredibly thorough, and easy to obtain; and they
are very easy to work on (in terms of accessability, etc). Etc, etc, etc.

The speeds/etc you are looking for are within their range. When filled with 4
16-channel data acquisition cards, you get 64 channels. They seem to have
quite powerful triggering/etc capabilities, and they are easy to use/control.

The only possible issue (for some people) is that the memories aren't large
(although you can chain identical DACs together to get slightly longer
memories). And I'll echo Tony's comments - ECL is pretty much de rigeur, and
as for making your own probes, fuhgeddaboutit; the 1240's probe pods (there
are two kinds, TTL-only, and 'pick a voltage') contain giant custom chips.

If you have 8 comparisons to spend I wonder if a modified binary chop
would have been more efficient? A standard binary chop would take
three comparisons, but I would have thought if you repeated each stage
twice (and a third time for up to two of them if they differed), that
would give you a more robust output...

   I'd go to a 16500C. Handy do-everything analyser mainframe, which can

   Of course you can go one step higher and get the 17500.

Subject: OT: Looking for the Tek 465 of Logic Analysers



Maybe only semi-OT.  I'm working on a couple of classiccmp-ish projects
(6303, 6309 and 68030) and I find the trusty old Tek 465 o-scope is no
longer compensating for my lack of design skill (or I'm getting better at
hiding bugs in my designs, depending how you look at it).  I'm looking for
a recommendation for a logic analyzer.  Considering my very modest design
constraints, I'm thinking:

- Suitable for 50MHz designs (really more like <16MHz, but you never know)
- 32 channels would be nice, ~128 probably perfect, less...you know...do
what you gotta do...
- No weird technologies in the design (all TTL/CMOS logic)
- I'm willing to spend a few $$ to get decent kit, but need to spend 
closer

to 465 money than TLA7012 money
- Decent analytics, hopefully more than "here's your traces...good luck"
- Ease of finding complete kit; nothing worse than dropping a dime on what
looks like a good deal only to find you're missing the unobtanium cable, 
or

the software disk that the vendor will be more than happy to provide you
only under a cripplingly expensive support contract.

A brief cruse of ePay didn't turn up much Tek/HP/Agilent older-generation
kit that looked like it fit the budget, but I'm not entirely sure I know
what I'm looking at.  I know there's a general allergy to anything USB
around here, and worse Windows-based USB software, but there is tons of
USB-based stuff that looked like a possibility for those who are willing 
to

hold their nose.

So have the USB logic analyzers achieved Willem levels of usefulness 
(which

one?), or is there a must-have Tek 465 moral equivalent I need to be
looking for?

Ditto. Well, I can't remember which model I was given, it's the one that's 
maxed out with 
'state' channels, but only the basic 'timing' channels. 

The manual is excellent (and available, AFAIK, from whoever Agilent became). 
The only schematic
you don't get is that of the video monitor -- and be warned that is a bit 
unconvenitonal as the scan 
lines are vertical (across the short dimension of the CRT). But you do get 
schematics of the CPU board,
state and timing boards, PSU, etc.

One practical thing I like is that the pod cables are 'captive' (held on by a 
screw-on metal cover plate) so
the pods are less likely to go walkabout (you've not seen my workshop :-))

As I mentioned earlier, it has both HPIB and HPIL interfaces. In theory you can 
control this thing from
an HP71B handheld (or an HP41 calculator?)

An HP1631 would be fun (it has a DSO board at the bottom as well as the LA 
functions).

Re: Looking for the Tek 465 of Logic Analysers

That's good to hear.
2 weeks ago I got an HP1630D and last week a 1631.
Both came with pods, but the first one did not have the "plug"
with the test leads, and the second one did. So I bought the second
one too for the plugs with leads. The 1631 looks quite identical to
the 1630, but the 1631 has additionally 2 analog inputs. Not sure
whether I will need them.


From memory, back in the 80-ties I used the HP64000 development

station. Additional boards can be put in the card cage that will give
you a 6800, 6809, 68000, 68020 etc, emulator pod. I am pretty sure
there are emulation boards with pods for almost any CPU of that
era. Intel CPUs too (yuk).  State and timing boards are also available
for the 64000. The 64000 is too expensive when offered ...  Recently
there was one on eBay for a few 100, but it was defective :-/
I'd love to get one.  Nostalgia I guess, but they were great.

The actual pods, which are plugged into the back of the instrument are
quite complex and have a ceramic hybrid circuit inside. Not the sort of thing
to attempt to replicate. The input to the pod is a pin header with an 
odd spacing. The lead from that to the grabber clips is just wires, so something
could be kludged up

They are much the same instrument -- I think the same manual covers both, Most 
of the
boards are the same (there may well be different firmware on the CPU board, but 
I think
that is the only change). The 1631 has an extra PCB at the bottom which 
contains the custom
input and ADC circuitry to make it act as a digital storage 'scope too.

Re: OT: Looking for the Tek 465 of Logic Analysers

[Marc Verdiell]

I'd suggest to go for the king of the hill at the time, and get an HP 16xx 
(163x, 165x, 166x, 167x) for all-in-ones or the 16500 if you like to modularize 
yourself, although tis latter one is much harder to put together since you have 
to get the frame, the plug ins, the software, etc... 
On the 16yx, the higher the y number, the better the machine (i.e faster, 
better screens, more memory). They are widely available, starting at below $100 
for the earlier machines, and up to $300-$400 for the later ones. I'd recommend 
to have at least one that has a hard disk, so you don't have to find or make an 
old LIF floppy to boot from.
As always the rub is the pods/probes. I had to complete my set separately, but 
they are also widely available.
This is a relatively small amount to pay for what these machines actually are. 
The later ones have the inverse assembler for the 68000.
I got the luxury one, a 1670G with the pattern generator (which I haven't found 
an excuse to use yet). Here it is at work:

Panaplex display history

[Jules Richardson]

JOOI, does anyone know when Panaplex 7-segment displays started going the 
way of the dodo, to be replaced with LED displays (and, on the back of 
that, what were the advantages of a Panaplex-type display over an LED one?)


I just saved a few boards from a dumpster with such displays on (they're 
actually Beckman ones, not Burroughs), but I was a little surprised to see 
IC dates into 1981; I thought by then things had moved over to LED.


I'm almost certain that they're from old gas pumps - maybe the displays are 
just more readable in bright sunlight than LED? (there's a sticker on one 
of the PSU boards with a 'shipping date' in 1999)


cheers

Re: Bitcoining on a 1401

[Marc Verdiell]

We do have two 1401s, and on a good day, they both work. No working 360s. But 
even if we could have the two 1401's talk to each other, it would still take 
about the age of the universe to mine a block. This is about the worst machine 
for scientific calculation, as it does BCD, character by character arithmetic, 
in a serial fashion, one BCD digit at a time. Hardware multiplication is an 
optional add-on feature on these machines (which we have)!

So no, you can never mine a real block in time with a 1401, or even a million 
of them. But that you could implement and run the algorithm is just a testament 
that the fundamentals of computing haven't changed, doubled with a vivid 
demonstration of the mind-boggling effects of Moore's Law over one generation. 
And having old hardware tackle modern tasks is just plain fun. And, lest I 
forget, a credit to the skill, talent and humor of our vintage programmer 
extraordinaire Ken, who joined us recently.

Panaplex and other 7-seg gas discharge displays were used in calculators up to 
the mid-70s. Actually one of the last uses in a calculator might be the HP-9815 
(1975/6):
http://www.cs.ubc.ca/~hilpert/eec/calcs/HP9815A.html
They were mostly used in desktops for the sake of the larger digit size but 
there were some pocket/handheld calcs that used the smaller versoions. In 
calcs, they were largely superseded by vacuum-flourescent displays which were 
easier to drive, had a longer life, and could also be made with bright, large 
digits.

Heathkit used them in some items into perhaps the late 70s.

They were also extensively in arcade/pinball games, as I'm sure many will 
recall. I'm not sure how late they were being incorporated into new designs in 
that arena.

In their heyday (early/mid-70s) I'd say they could produce a larger, more 
uniform, better contrast, display than the then-early LEDs. Would have to look 
at specs and some calculations but they were probably more energy efficient 
than LEDs.

Yes, to be accurate, Panaplex was a Burroughs trademark. There was the Panaplex 
I series which had a metal grid anode in front of the segments for the anode, 
and the more-prevalent Panaplex II which has a conductive coating on the glass 
for the anode.

The Burroughs and Beckman displays are different in design. Generically, I 
refer to them as 7-segment gas-discharge displays. There were some 
lesser-produced designs from Japanese manufacturers.

Generally, their failing seems to be the cathode poisoning common to all neon 
bulbs, and 'burning' of the thin conductive anode coating where applicable.

Funny, I was about to mention that use. I remember them in use on gas pumps up 
to somewhere around the late-80s or early-90s. One of my bike routes takes me 
on a dike behind an industrial area. Sometime around the mid-90s I remember 
there being a yard filled with scrapped pumps, a lot of them missing the 
display/keyboard cover, so all the displays mounted on the big controller 
boards could be seen. I wanted to rescue some of them but never got around to 
pursuing it. I was kind of dissuaded by the thought they had mostly seen a long 
and continuous service life and may now(then) be of questionable reliability.

Re: Panaplex display history

[Chuck Guzis]

I'll assume that you've seen the "roll your own" panaplex displays. 
Does that count as manufacture?

Well, you have to understand that the 1401 was used as an I/O device for 
the 7090//94 (cf. "SPOOL"), which were *real* scientific computers of 
the time.  You don't happen to have any of those, do you?


Wonder how long it would take on a Microchip low-end PIC MCU?

Jumping in on the bandwagon.

My observation of the default GUI was it was pretty darn quick, not even taking

As far as I remember it was jumper configurable to could act as an 11/34,
11/44, 11/70. Not sure if an 11/84 was also possible.
