Not _impossible_ (since the RP11 does have one row of 36 lights - no doubt
because it can be used to read packs written by PDP-10's - it's the shift
register for reading the bit stream off the drive) but I'd say less likely,
given the two rows of 36 bits.
Or maybe not; one is a shift register, the other is a Longitudinal Parity
accumulator, which would also naturally be the same word length.

In fact, I have a picture of an RP11 panel, and... the one in the back _is_
an RP11! Well, knock me over with a feather!

I've seen images of (or worked out the light pattern for) two, the TS08 and
the RK08, and this isn't either one. (Both have only two rows of lights.)
I wonder if there's an RP08? {Checks} Yes, there is. Do we have prints?
{Checks} Yes. Alas, the scans of the connector pages of the prints are
pretty bad, but it doesn't seem to support a display panel.

Hmm. Could be; now that I have the better picture, let me see what I can
turn up.
I note the 'sector word count' has 7 bits in it, which kind of implies a
PDP-10 - most PDP-11 disks had 512 bytes / 256 words -> 8 bits. Although
maybe there are a few early ones that had 256 byte sectors, I have this vague
bit set that there were; will have to check that.
I think I'm going to have to create a page for DEC indicator pabels!

Teletype services
I've been trying for the past week to verify that telephony on my teletype machine (model 33) is functioning properly but the biggest hurdle I am running into is I have nothing to easily dial into. Everyone I know off hand either don't have a modem anymore or theirs is a Winmodem which won't work. There's only one phone line into the residence here and those bluetooth to cellular POTS bridges are too lossy to make do and connect to a machine here. There is that youtube video of the model 37 apparently connecting to a system at the Living Computer Museum in 2013 (MikoF6KZjm0) where they dialed into a BBS I've never seen listed anywhere but the number listed no longer seems to work and in the description it states the service is no longer available. What other public systems are still out there that will work this speed or possibly better yet, is there anyone out there willing to try a teletype-to-teletype conversation? -John

(there are some issues of the correct name for > that) If it's a model 33 it has to be ASCII. The 'Baudot' one is the Model 32 IIRC. [Yes OK, there were plenty of other 'Baudot' machines made by Teletype, but the Model 32 is similar to the Model 33] IIRC 'Baudot' should really be called ITA2. ITA5 is ASCII. (ITA = International Telegraph Alphabet). Is ITA1 Morse? What were/are ITA3 and ITA4? The original Baudot code, as used on the 5-key chording keyboard thing was also a 5 level code, but quite different in how the characters were encoded. There was also Murray code which is similar to ITA2 but one major difference is that there are 'letter space' and 'figure space' codes (which move the carriage one character and select the appropriate 'shift' rather than letters and figures shift characters which just select the shift, along with a seprate space character. So in Murray code you could not send ABC12XY63, it would have to be ABC 12 XY 63 -tony

There is strong possibility that one of those bridges might not work.

Some time back I was thinking of making something similar, although to me it's just a simple state machine and doesn't need a microcontroller. Heck, originally it was done by the telephone company using relays. I don't like using thousands of components when a couple of dozen will do :-) But the control circuit is the easy part, it's things like the power supplies, ringing generator, etc that are the major part of the work. The ringing voltage in particular is a pain, it's AC, and at a fairly low frequency (16.67Hz to 25Hz depending on country). Some devices, particular classic telephones with a mechanical ringer, do not work correctly on a 50Hz or 60Hz ringing voltage taken from a mains transformer. After sketching out a design, I realised that the cost of the main bits (line switching relays, the power supply for the ringing voltage, the 48V PSU for the line 'battery' voltage, etc was comparable to a cheap ready-build device to do much the same job. Of course the ready-built one would be difficult to keep going so I probably wouldn't go that route But anyway, telephone line simulators do turn up on Ebay and I was lucky enough to find a non-working one for (I think) $25. I figured that even if I couldn't fix it it would contain useful bits for power supplies, etc. After fixing the mains switch and reseating the socketed ICs it sprang to life and almost worked. After replacing a couple of LM311 comparators and a 3 terminal regulator it was perfect. This thing is _complicated_. IIRC there are 7 microprocessors/microcontrollers in it. Around 400-500 ICs spread over 3 main PCBs and 7 smaller PCBs (some of which are just switches or connectors). It does do a lot though, it will generate the correct call progress tones and ringing voltage for just about any countries system. It will deliberately introduce noise (from a shift register with XOR feedback) or degrade the line (handled by a classic DSP -- a TMS320 IIRC). Do I need all that for fooling around with old telephones and modems? No. But it was actually the cheapest solution and it is a nice, classic, piece of test gear. -tony

Ah yes... One of the classic tests for problems in the receiver and comms link, but not the only one. A system with poor low frequency response (for example) might handle alternating mark and space correctly but fall down on things like 0 I have a test message generator that can sent that, various alternating signals (without start and stop bits), user-entered characters (on a row of switches) and so on. And distort them by lengthening and shortening pulses to check how well the receiving device copes with mangled signals. I also have the distortion measuring set, a special oscilloscope to check for distorted signals, test relays for contact bounce, bias and transit time, etc. I really must get my Creed 7E and 444 running again... -tony

Curious as to the setup you are attempting this with, i.e. exactly what modem are you using? One in the base of the 33 or some common external one? I'm not familiar with all the possible modem variations one might find in a 33, but AIUI the modem for the 33 at the standard 110 bps was Bell 101 standard. There's not going to be a lot to talk to out there using the old parameters. Even if someone had an auto-baud dial-in setup out there somewhere, I wouldn't anticipate it being compatible. We have a 101-standard modem (in the base of a 33) around here, but have never tried it or tried connecting it to a phone line, I'm also not familiar with it enough to know how originate/answer issues are dealt with (whether it can do both) for such 33 to 33 communication.

If you have a "Smart Modem" (ie, stand alone unit with serial port) you can connect it to the modem in the Teletype with a battery-- like, a 9V battery-- in series with the phone line between the two. Then you use the Teletype modem to place a call to any random number and command the Smart Modem to go off-hook with "ATA". This will cause it to generate answer tones and the Teletype originate modem will "connect" and off you go. You don't need a ring generator or any ring voltage on the line since you can manually command the Smart Modem at the answer end to answer with the "ATA" command. I pretty much ignored "WinModems" in the day but I would think that if they can do answer mode, this approach would work with one of those as well. Open the terminal app on the Windows box in which this WinModem is installed and simply enter "ATA" to cause it to go off-hook in answer mode. If the 9V battery is in series with the line to the modem in the Teletype, you should be good. There might be polarity issues so reverse the battery if it doesn't work the first time.

Highest likelihood it is a Bell 103 which is AFSK at 300 baud or less. The problem you have with Teletype to Teletype with telephone modems is that both ends are likely to be originate modems-- meaning they will have the same tone pairs for transmitting and receiving and thus cannot talk to each other. One end needs to be Originate (which is the Teletype) and the other end needs to be Answer with the opposite tone pairs-- so that the transmit tones are received by the other side and vise-versa. https://en.wikipedia.org/wiki/Bell_103_modem Some very old acoustic couplers did have a way to reverse the tone pairs but they were not very common. -- Chris Elmquist

I haven't seen those internals for a long time. System/23 was the first product I worked on at IBM (wrote about 20% of the total ROM code for it). If anyone knows where one is for a "reasonable" amount, I'd be interested mainly for nostalgia reasons. ;-) Some interesting facts: * The IBM 5120 (follow on to the 5110) used the same "skins" as the System/23. That was because (for a number of reasons) System/23 was late and IBM wanted something in the market and the 5110 was getting a bit long in the tooth. So when IBM decided to repackage the 5110 they used the already existing skins for the System/23. * The expansion bus in the IBM PC was the same bus as the System/23. The connector was rotated 180* so that some of the less expensive cards from the PC couldn't be used in the System/23. The other reason for this was since the IBM PC was done on a "shoe string" budget, they could take the System/23 cards and only had to do some minimal re-layout of the board. TTFN - Guy

I can't even guess how much it would cost to ship a System/23 from California to NZ! I think I found Mike's Youtube videos of one of his other System/23. It even has blinkenlights! Dang it, now I'm trying to figure out where I'd hypothetically stick a System/23 in my little house. Probably in the breakfast nook, assuming it would even fit through the front door. I doubt it could make the turns into my computer room. If I call it a "desk" and then put more computers on top of it, then does it really occupy any space? :) I managed to shove a VAX-11/730 through the front door: http://www.nf6x.net/2014/05/nothing-sucks-power-like-a-vax/ But I don't think a System/32 would fit unless it can be broken down into pieces no wider than a 19" rack. -- Mark J.
