Greetings again! I'm in need of some printed documentation with regards to the HP2100 or HP21MX diagnostics. While each of the diagnostics are available separately, a large chunk of diagnostics are put on a single set of 3 paper tapes. I do have the tapes, but not the manual that goes with it. The manual is 24396-14001. That's the one I need as this "manual" actually is a manual on each diagnostic included in the three tapes above. Can any of the 2100 or 21MX folks check and see if they have this manual laying around? In the event no one has 24396-14001, I would also be able to just get along with the manuals on a few of the diagnostics. Those critical ones would be: 02100-90219 Core memory (2100/16/15/14) 24395-90001 Semiconductor memory (21MX) 02100-90221 Memory Parity Check 02100-90216 Power fail auto restart 24391-90001 General purpose register 24322-90002 Direct Memory Access (2100/21MX) Thanks for checking!
