[cctalk] Teletypes for sale - redux with pics on google drive and contact info.
Hey folks. I need to re-home a bunch of cool old Teletype Corporation machines. Working condition unknown, and also have some spare parts. I am not out to make a mint, so make offer! They seem mostly complete, in varying condition. Some are nicer than others. They all worked when stored (years ago) The following need to find new homes: TT Model 28 ASR (3 of these) TT Model 28 KSR (2 of these) TT Model 28 RO (2 of these) Extra Model 28 Parts TT Model 28 Floor Standing Paper Punch TT Model 32 Baudot TT Model 35 KSR (heavy duty version of the ASR-33) TT Model 35 ASR (Floor stand heavy duty, 2 of these, one Telex) TT Model 40 Dataspeed Teletype manuals and documentation for each model Tell your friends! Delivery is possible. I can assist with loading. Message me for details.

[cctalk] GEAC
Here's a question for all our Computer Museum curators. Have any of the old GEAC Library systems ever been salvaged and put into a museum? They were curious boxes and I think would make a nice addition to a collection. bill

Are you referring to GE/PAC RTMOS?

Yes, we had one at the University of Scranton until it was replaced by a software only solution running on VAX/VMS. bill

Mike you should post this on the classic computer discord under teletypes. Do you want an invite to the discord or do you already have one? The teletype discord is fairly active lately.

I do have some old DEC rails, but I have a fair amount of equipment, from both DEC and other manufacturers, for which those rails are not suitable. Does anyone have any specific recommendations for shelving? (where equipment could just be slid on top of, if the equipment isn't too wide - some pieces are very close to 19 inches all by themselves, and were designed for front cantilever style mounting.) Rack makers sell these; for example https://www.budind.com/racks-cabinets-accessories/ or https://www.dell.com/en-us/search/server%20rack%20shelves but I would expect any number of places that produce racks have them. I have an H960 and needed a solution for a 3U 19 storage array that can attach in the front but needs more support and doesn't mate up with the H960 rear rails. So rather than spend significant money on a shelf, I just installed a pair of angle irons from front to back (vertical flange down) and set the array on that. Since it's close to 19 inches wide, that simple solution fully supports it. For a heavy oscilloscope I wanted to install as well, I did something similar: angle iron supporting a sheet of plywood. In that case, it has some additional angle irons running across, to keep the plywood from bowing under the load. paul Amazon has them at lower prices than those -- I was just wondering if anyone in their travels found a particular one that worked well in a DEC rack (e.g. H960) JRJ
[cctalk] Re: Tadpole/RDI UltraBooks - UNIX notebooks - species needs rescue...
Before heading to some short vacation first of all: Thanks to all contributers! I built an adapter for reading the NVRAMs in my programmers (CE2 pulled to VCC using a resistor, pin 1 isolated) - this adapter us usable for both the DS1643 and the DS1553. The TopMax2 software has got a bug - it reads 1643 only as 4k device so I read all NVRAMs selecting the DS1225 using my Galep-III (software Galep32) and my TopMax2. Results: (1) The contents of the 1643s (unmodified from UltraBooks) showed varying content with lot of 55 and AA as in Santo's dump above. Writing to NVRAM is of course not persistent. (2) The contents of my modified 1553 (from UltraBookIIi with the external battery attached) are stable (so the battery works) but the content is ramdom. The oscillator is stopped hence no update of the clock. After starting that in the UltraBookIIi the clock still is stopped, so the device is in its factory-fresh mode and the firmware does not start clock. I can write the data section and any modification is persistent (again: the external battery works). After my vacation I will zero the RAM, start the clock, set reasonable values for the watchdog and hostid and give it a new try. The problems to be solved before: The TopMax2 just died and the Galep-III can not write the configuration section - it writes all bytes in one run and than does a verify, but to write the upper 16 bytes first the write bit needs to be set, than data should be written and it gets latched only in clearing the write bit again. That process simply is not present in the Galep32 software because the device gets powered down before verify :-( Stay tuned...
