But it won't fit in my A600 or A1200. 
Everything fits if you have a hammer at hand

What works with your A600/1200 is:
HoneyBee Joypad
Cameron Handyscanner (only if it is equipped with a Zorroboard)
128 MB PS/2 extra-slim, extra fast (50ns) for Blizzard turbocards an others (if you have a turbocard)
worldtime-receiver for batteryless amiga-systems
complete package OS 1.3
Soundsampler Megalosound from Microdeal (Hard Disk Recording)
original Commodore mouse
Handbook Systemsoftware
So there are a lot options for your systems
