For a start, the amigas PCMCIA port is only 16bits wide. CBM plonked this port into the A600 &A1200 before the final PCMCIA spec was nailed down !
10/100 cards are PC Card type, and are incompatible with the amigas PCMCIA slot

Duh, PCMCIA _IS_ 16 bit. That's not the problem with the implementation. You see, it's a matter of only having 68 available pins. For PCMCIA, which is basically ISA, you have 16 bits for data and  26 bits for address. For Cardbus, which is basically PCI, you get away with 32 bits in total, since Data and Address runs on the same pins physically (time multiplexing).

So please don't make it sound like there's an "Amiga PCMCIA" and a "regular PCMCIA". It's "PCMCIA" or "Cardbus". "PC Card" is marketdroid speak for "68 pin thingie you plug into the hole on the side of laptop thingies", and doesn't tell you anything about what protocol it supports.

By the way, the bandwidth of the a1200 PCMCIA-port is 65536 bits/sec. and this is due to hardware in the to the port, not the processor.

64kbps?

Go somewhere else with that FUD, please. Add a 0 behind that and you are getting somewhere... (or are you trying to surf the net on a 2M 14MHz A1200? In that case, you should consider getting a more fruitful hobby ;-) )

In any case, I have seen ZIP drives manage over 1.2MB (wee, isn't that almost 10Mbit, oh yes I think it is) per second over a Squirrel. Which is higher, do you think? 64k or 10M?
