| Apr 7, 2024 at 21:39 | comment | added | rbanffy | A small correction - the model is S26361-K164-V1 - and I'll add images as soon as I can. Udo pointed me to a PDF that has a diagram for the back, on page 53 (4-12). The document is at oldcomputers-ddns.org/public/pub/rechner/siemens/mx-rm/pc-mx2/… . I added a photo of a seemingly identical unit (credit Alessandra Schellnegger) to the question. | |
| Apr 6, 2024 at 13:06 | comment | added | Raffzahn | @rbanffy Now I really need to see pictures, including connectors, as with the regular screen on top it shouldn't be a K164. I have some 97801 in storage (and two older ones in my garage). They were plenty, but since most were used in businesses, especially large companies/government, they tend to be scrapped when no longer used, not stored in some basement :)) Udo Möller is well known for his NS32xxx work (also lives just a few km from here). No, power is not separate, but part of the screen connector. That way it ges switched on by the CPU using lower voltages. Done for better handling. | |
| Apr 6, 2024 at 12:21 | comment | added | rbanffy | This unit has the screen integrated on top of the brains, with a signal cable connecting it to the main board on the outside. Power is probably connected on the inside. I've been in contact with the only other person who seems to own something similar (cpu-ns32k.net/Siemens.html). It's one weird machine. I'll add more photos as I work on it. | |

| Apr 5, 2024 at 12:15 | comment | added | Raffzahn | @manassehkatz-Moving2Codidact BTW, those micro terminals (97801) were introduced in 1983 or 84 (IIRC) and accept a superset of VT100 instruction including all that code switching and so on. So adapting one to use with other systems might not be hard at all. Internally the first series was 8085 based, the later (like the above) used some intel based micro controller (8035 possibly) | |
| Apr 5, 2024 at 11:23 | comment | added | Raffzahn | @manassehkatz-Moving2Codidact well, yes and no.When introduced for the new 970 series mainframe terminals it was just local I/O. Host connection was done using BAM at 288 kBit/s (Hdx). Only with the later Unix (Sinix) based micros it also was used as host interface. So there was some pressure upwards :)) The first 97801 series was build using mostly 9780 (the mainframe terminal) components. Including its awesome keyboard. Still miss that feeling. I'd be even willing to canibalize some to finally build an acceptable PC keyboard. They are just way to hard to find. | |
| Apr 5, 2024 at 3:19 | comment | added | manassehkatz-Moving 2 Codidact | 38.4k is pretty good for that time. Terminals I used at the time (well, actually a few years later) were generally maximum 19.2k. I checked and the VT100 - also introduced in 1978 - was max. 19.2k. | |
