CiTOH terminals (was Re: old friend is slimming down the warehouse)

I'm in Ohio and I get out to Chicago and NJ a couple of times a year. I have a cabinet of CiTOH terminals I bought from my employer "some years ago". ;-) We used an assortment of DEC VT10x, VT220, CiTOH 101 and CiTOH 101e terminals. ISTR the CiTOHs were as much as $800 cheaper than DEC terminals at the time. They were robust and at one point, I pulled out of the manuals the magic escape sequence to "switch sessions" and use the local printer port as a second comms line (we just had to bang out a custom DB25 adapter since the entire company was standardized on Nevada Western 6p6c modular serial and we didn't have a box of the right adapters for the printer port). It was awesome having two live lines in front of our usual switchbox setup for connecting to multiple hosts. > ... knew one of the developers Neat! > F/W was done in the US I can no longer remember the key combination but the > terminal would let you know who did it That would be fun to look up. > Anyone wants to gain a cubic foot or two let me know You got it! -ethan

by jnc＠mercury.lcs.mit.edu

> From: Adrian Stoness >> its an 11 of some sort not sure witch one Ah, OK. That's either an -11/04 or -11/34 in the top left corner, with either an RX01 or RX02 above it. (Not enought detail in the image to say.) The rest of it seems to all be some sort of custom medical or other specialized hardware. (The /04 and /34 are very similar - the only difference is which processor card(s) is/are plugged in - you can convert most -11/04's [it depends on the specific backplane in use] to -11/34's by pulling the M7263 KD11-D -11/04 processor card, and plugging in instead the M8265 & M8266 KD11-EA -11/34A processor cards, which still seem to be relatively prevalent.)

"Key" to open an HP 264X terminal

by curiousmarc3＠gmail.com

Questions for our HP specialists. I can't open the case of the HP 264x terminals I just got. I see from the manual there is a small slot on the side in which you have to insert a "key". Is the key just a small blade tool or does it have to be more special shape than that? Marc

Quadra 660AV what's with the "PowerPC" label?

by swiftgriggs＠gmail.com

I noticed someone selling a 660AV in my area on Craigslist. I went and got it because for $50 he had a nice little Apple display with the machine that matches my Quadra 700 and an Apple Adjustable Keyboard in good condition to go with it. Turns out he gave me a whole slew of spare mice and an extra Apple Design keyboard (a good, if ugly and PeeCee lookin', spare). The 660AV was dead when I brought it home. It would bong normally but wouldn't produce any video. The RGB video connector on the monitor was smashed out of shape, too. So, I used a sheet metal tool to re-smash the connector back into the right shape, and some needle nosed pliers to straighten the pins. Then I replaced the PRAM battery on the mobo and that fixed it. I guess they don't quite last 23 years. The weird thing about this machine is that it says "PowerPC" right on the front, but it's *NOT* a PPC. It's most definitely a 25Mhz 040'. I wonder why that's there? Maybe the guy took the badge from another system, but I don't think so. This was the original owner. I also wonder why this one is called a "Quadra" when I know I used to have a 660AV that was a "Centris". Wikipedia seems to imply it was just a marketing name change only. However, the article also mentions that most of the Quadras don't have a floppy with motorized eject. Well, this one does. Perhaps it was replaced. I just wonder what's up with these little nuances. The best part of this deal is that the Apple Adjustable keyboard feels mechanical, and I've been pretty impressed with it so far (once you carefully remove the plastic wristrests). It was a bit yellowed, but a bit of retr0brite treatment restored it to bright white. It looks pretty much new, now. I gotta do the Quadra 700 and 660AV next. They aren't badly yellowed, but somewhat. Since neither is scratched up, they should restore nicely. My plan is to run A/UX on the Quadra 700 and MacOS 8.1 on the 660AV. Right now I have everything in pieces. I'm waiting on another SCSI2SD to come to be able to set them both up. Plus, I just got the one SCSI2SD and I'm in the process of benchmarking it on several different OSs. I wish the US vendor would sell the newer (v6) board, as it's supposed to support 10MB/s synchronous (if your SD card can do it, and most can these days). All they have on Ebay right now are the older 5.x based cards (which is like the one I have now). -Swift

DL11 configuration for pdp11gui

by fritzm＠fritzm.org

Hi folks, I've started to look into hooking up pdp11gui to my 11/45 w/ M9301. Does anybody here know how the console DL11 should be configured for this wrt. data bits, parity, stop-bits? I haven't seen this mentioned in the documentation or tutorials. thanks, --FritzM.

VT52 oscillator

by fritzm＠fritzm.org

It seems the clock oscillator chip (E1, 13.824 Mhz) on my VT52 is flaking out. It has become very vibration sensitive. I tried reflowing its solder connections, but it has not seemed to help much... Anybody have a spare, or suggestions/advice for a replacement? There's certainly room enough in there to build and mount a small oscillator board if the old/original parts are too hard to find or are all similarly flaky with age at this point. Looking around on the web, the symptoms of the resulting failure mode seem pretty common (no scan, but a slight tap on the right side of the chassis will sometime restore, though I suppose that could be many other things as well!) cheers, --FritzM.
