Once my collection was much larger: all the IBM’ish stuff has moved on to new homes.
Remaining are the Osborne 1 CPM, the first 6 Macintosh monochrome (Classic II not shown), and 2 AppleII+ with disk drives. One of the II+ has the Integer card and one has a CPM card. From the days gone by department. At one time, they all worked perfectly, but I have neglected them over many years (excepting dusting) and I’m sure the Mac floppy drives are definitely in need of re-lub to allow the single-sided floppy to eject properly.

Not shown is the PET 2001 which I believe I have posted previously.

The CBM Model 4032 was the PET I cut my teeth on, and the Apple II of course.. also an Acorn Atom, Microtan Tangerine 65 .. Acorn Electron… then I moved on to Xenix boxes (Altos mainly). I still have the Acorn Atom somewhere and a ZX81 both built from kits. The stm32f103c8t6 pretty much outperforms the lot of them put together, and consumes 1/1000th of the power.

I remember with great trepidation, taking a dremel tool to my battery case to allow a 25 pin SCSI connector to be jammed in its place. Then I connected a ribbon cable to some clip on thing that piggybacked on the CPU pins. My memory is pretty foggy after 30 years. I think it might have been the Dove board:

The only repair I made was the substitution of the 6510 of a C64 due of a recorder port broken and a substitution of a C128 RAM chip that was stuck, so I discovered that in C64 and C128 every bit of a byte is in a different chip.
