It?s a 9-slot variant that says HP-1000 M-Series on the front panel. From what I can tell the front panel appears to be the same as any of the other HP-1000 series. What I?m trying to figure out is what the actual CPU configuration is without disassembly (which I still need to figure out) so that I can actually examine the boards. Thanks.

Thanks all! The trick was opening up the front panel (I?m used to keylocks that are only electrical and not just physical). Here?s the HP label with the options: CPU 2103 MEM BP 1713 IO BP 1727 Accessories 12992B 12944B 2102B 12897B 12892B 12746A In opening the panel on the front card cage, I saw that it only had 16K of memory. :-( I?ll see about firing it up and if that goes well (anyone have suggestions for this type of mini?) I?ll see if I find more memory and suitable peripherals. Thanks.

It would be helpful to see a closeup of the read card cage (with readable labels), as well as the front card cage. The front card cage is accessed by unlocking the panel and removing the cover on the right side over the card cage. That's where the memory boards live. > > On Mon, 12 Aug 2019, Guy Sotomayor Jr via cctalk wrote: > >> It?s a 9-slot variant that says HP-1000 M-Series on the front panel.

Except that I don?t have a 12745A memory board, I believe it?s a 12746A which I think I saw was a 16K board. Thanks.
