I found some QBUS boards that I can't identify from the field guide. The numbers are: M8950 M8951 M8952 M8953 M8955 M8958 M8970 M8971 M8972 M8973 I believe some of them are parts of a tape controller, and one of the boards had an i8085 along with some ROMs. There's also a board with a bunch of ROMs that has the notation "8085 ROM BOARD". I have no idea of the origin of the boards. I found them in a cabinet while I was looking for some documentation. -- Eric Dittman dittman(a)dittman.net
