I still have (in working condition) :

1) My first TRS-80 (with home assembled expansion interface, from scrap
components off of an old ALCATEL board) with total 48 k of RAM and 2
160k floppy drives.

2) My Canon X-07 (NSC-800 CPU - like a hyped up Z-80) and a 40 kb RAM
expansion that I soldered myself inside the machine with about 40 15cm
wires going to the address selector chip and the existing memory chip.
Canon had sent me the full schematics and doc of the machine. Still have
it all.

3) My wife's Atari 1040 ST. I have no idea how to use it, but it boots.

4) My first TI-57 with variable CPU clock hack, hacked audio out,
external keyboard plug, external control plug with home made logic to
enable the TI 57 to close or open a relay switch by program. (TI send me
the wireing diagrams of the calc, at the time, and I unsoldered the chip
and put it on a socket).

All this stuff works... I should open a museum.
