For sale is a two disk set of Master Diagnostics software by NIKROM.
Included are the programs needed to test the Apple II & II+, IIc and IIe. Also included is a copy of the Apple Diagnostics for the Apple IIGS v 4.0 since I had an extra side on one disk.
Diagnostic tests include ROM and RAM testing, 80-column display tests, mouse and monitor diagnostics, sound tests, disk drive analyzer routines, port analysis, and monitor routine tests. This suite was used to verify the hardware health of Apple II machines, helping users and technicians diagnose failing components by running thorough hardware checks.
I prefer to ship in a box rather than cardboard mailers since it provides better protection during shipping so my shipping prices reflect this additional cost.
Please let me know if you have any questions.
