There are basicly 2 kinds of Amiga-KBDs (not counting those on A1000,A2000A and A600).
1)Contacts and KBD-CPU on one PCB, those came with the A2000, A3000 and early A4000.
There is also a version with 2 LEDs which was used in A500(+), another cheap source
for spares.
2) Contact-foils,ending in a ~20 "pin" foil-plug. Those came with the A1200 and newer
A4000 (only Escom ?). The KBD-CPU is either on the mobo (A1200) or on a small
PCB inside the KBD (A4000). These foils can be changed, but the A1200-version
has a longer "plug", so that might proove a a bit harder.
I also heard of some A500s having a foil-KBD, with the CPU-PCB.
