The sticker says 81-478.

The mainboard is assembly #81-809, and has quite a few unstuffed 
components in the upper right corner

According to this site:


It uses the Universal ROM and must run CP/M 2.2U1

It's unclear to me which of the images on Dave's site would work.  I 
suppose I can try all of them (the system disks from the KII, the K3*83, 
the K4, and the K10), but I'm not sure if I'll know whether the issues 
is an system mismatch or a drive issue.
