Thanks Eric! I had found some of the MAPS, but with the info that you've provided I've been able to locate pdf copies of both the 5110 maintenance manual and that for the 5103. No luck on the 5114, yet, but I'll keep looking. Does anybody here disagree with my assumption that it is most likely to be the Display ROS that is faulty? It appears to be the only ROS that isn't checked by the Bring-Up Diagnostic, which may explain how I got as far as I did.

NCR terminal
I have an NCR labelled ADDS 2020 terminal that emulates the NCR 7930 and 7901. Has anyone a manual for those NCR terminals that describes the control sequences? OTOH a firmware dump of the ANSI firmware for the 2020 would be fine, too. Christian

Re: IBM 5110 - Where does the character set live? And other questions.
Hi Christian, I might have some better documentation that I just haven't had a chance to scan yet. I have several binders that make up the IBM 5110 System Library. In terms of manuals enclosed for the 5110, I have the following that I can scan in the next week or so so that you can put a copy of these on his site. Can you let me know what you need from this list? Make note of the revisions because this set looks up to date (to a point) with IBM Tech Newsletters that include revisions and page changes. 5110 System Library Binder 1 SY31-0550-2 IBM 5110 Computer Maintenance Information Manual SY31-0551-0 IBM 5114 Diskette Unit Maintenance Information Manual SY31-0414-3 IBM 5103 Printer Maintenance Information Manual SY31-0581-0 IBM 5110 Language Support Maintenance Information Manual S131-0627-1 IBM 5110 Computer Parts Catalog S131-0626-0 IBM 5114 Diskette Unit Parts Catalog S131-0598-3 IBM 5103 Printer Parts Catalog SY31-0553-1 IBM 5110 Maintenance Analysis Procedures 5110 System Library Binder 2 GA21-9300-0 IBM 5110 General Information and Physical Planning Manual SA21-9311-0 IBM 5110 Customer Support Functions Reference Manual SA21-9308-1 IBM 5110 BASIC Reference Manual 5110 System Library Binder 3 SA21-9306-0 IBM 5110 BASIC Introduction SA21-9307-1 IBM 5110 BASIC User's Guide SA21-9318-0 IBM 5110 Computing System Setup Procedure Hope this helps, Santo On Tue, Jul 11, 2017 at 11:28 AM, Christian Corti via cctalk < cctalk@classiccmp.org> wrote: > On Tue, 11 Jul 2017, Robert wrote: > >> maintenance manual and that for the 5103.

Any info about Plessey floppy drive/controller?
Hi! I have a Plessey floppy as part of a 11/34 system. Does anyone have info about it? It appears that the controller is similar to the XCV21 controller. https://i.imgur.com/NxGPBFN.jpg https://i.imgur.com/NOg7WfZ.jpg https://i.imgur.com/HnhmO33.jpg The XCV21 manual is available on bitsavers. It appears that it supports double sided drives. How would that be compatible RX01 and RX02?

This was part of a PDP-11/34 system for radiation dose measurement at a hospital. Is it something general or very special purpose? https://i.imgur.com/rTAzl9o.jpg https://i.imgur.com/vhPdvi7.jpg https://i.imgur.com/vWqloGb.jpg https://i.imgur.com/O98aA7F.jpg https://i.imgur.com/No72LDm.jpg https://i.imgur.com/HiHirxQ.jpg Some kind of bitslice procesor with high speed TRW A/D or D/A? Would be interesting to have a bit more info on it!

With all the bit-slice, memory and coaxial inputs/outputs I would venture it was used for nuclear imaging. For example - Thallium-201 is used for cardiac imaging. The floppy is probably RX02 compatibly. Check for two wired heads. Jerry j...@ieee.org

Thanks for checking. Yes, that does seem to be the more common card. As far as I know, the 12653A was used only for the HP 2767 (a rebranded Data Products 2310), whereas the 12845B was used for a number of other HP printers. > Reading some more, it is meant for the 2607/261x series of printers, > which apparently use a narrower 7 bit interface (the 12566 is a 16 bit > interface card). Which is all a bit odd, as the 2767 also uses 7 bits for data. Unlike the other printers that use differential interfaces, the 2767 uses single-ended TTL-level (more or less) drivers and receivers, which may explain the use of the microcircuit-based interface. The 2767 signal drivers are adjustable for a 3- to 8-volt output level, so perhaps the 12635A "modification" was to clip the inputs to avoid damaging the standard microcircuit receivers (7400 TTL with an absolute maximum input spec of 5.5 V). In the absence of a manual, I was hoping that a photograph would reveal the modification. > But maybe you can inspire yourself from it. The existing 2767/12653 simulation was reverse-engineered from the diagnostic and OS drivers. Although it works, I was hoping for something more authoritative so that the code could serve as a reference for the now-extinct hardware. -- Dave
SIMH .tap file 7 track?
This is one that I haven't seen addressed. If I'm reading a 7-track tape and writing a SIMH .tap file, what's the custom? 6 bits per 8-bit byte, right-justified (i.e. 2 high bits zero-filled)? Just wondering if there's a convention established for this. --Chuck

If you use a single sided drive its compatable with RX01/02 and can read and write them. If you have a two sided drive its still compatable but media generated in two sided mode will be incompatable with RX01/02. That simple. The yabut is you must have the Plessy driver for it as the stock DX/DY knows nothing of the two sided modes.. And any two or single sided drive will only be used single sided. Allison
