RCA Spectra 70 reference cards

We recently received a donation from retired computer programmer Robert Kaunitz of Maryland, including manuals and a special IBM PC XT.

What’s so special about the XT? The computer’s hard drive contains a user interface program that Mr. Kaunitz developed called MARA (Machine Assistant Ready and Able). We look forward to trying it out as soon as some hardware repairs are complete — the hard drive controller is bad, Mr. Kaunitz told us.

Additionally, we’d like to thank Mr. Kaunitz for the following items:

• Autonetics Recomp III Programming Manual and Fortran manual
• IBM PC DOS 2.02 and manuals
• MDBS KnowledgeMan database software and manuals
• Ferrite cores
• RCA Spectra 70 reference cards
• IBM System/370 reference cards
• Data General Eclipse reference card
• IBM flowcharting template
