I'm selling a Microbotics 8MB RAM board on
eBay at the moment. Not sure where in the world you are though. It might be too far for you.
I believe there's a fix for the PCMCIA problem when using an expansion. I'll see if I can track down what needs to be done.
Edit: I didn't make this. It's from Aminet. I have never done this modification so I cannot tell you if it works, but I heard of others doing it. I believe
AmiKit even has a product that will fix the PCMCIA reset issue with a socket that clips over the Gayle chip.
The A1200 (and A600?) PCMCIA-port has a bug which causes some PCMCIA-cards
(especially ethernet-cards) not to work after hardreset until you remove
the card and insert it again while power is on.
It seems as if the A1200 is not generating any reset-signal for the PCMCIA-
port. The problem is easily solved by soldering a 10uF capacitor between
CC_RESET and and Vcc. The CC_RESET is active high. The cathode (-) of the
capacitor should be at CC_RESET.
CC_RESET can be found on pin 5 of Gayle (U5) and Vcc on R715A (the end which
is near Gayle).
WARNING!
Although this is a very simple thing to solder please consult a professional
if you are not good at soldering. I take no responsibility for any damages
caused by doing anything described in this file.
Thanks to
