fit a 4MB simm and a socket
look in the wiki
or ask alanH for his board not sure if he is making a run
replaces the board you have and ide and tos 2.06 etc for a small price
i feel if you replaced the cables and i feel your not daft
perhaps some ic;s have failed
so changing it for a many update board
simply first reverse the mod and fit something better instead
to a working 512K ?? machine??
if your determined
then if you have fried ram
you can add problems too your system
.... not easy too fix...
i suspect some chips are fried
its not worth fixing it better to add a 4MB simm and a switch to give you 1MB instead for some games etc on st
if you fit alanh and perhaps others mods instead its a better use of your STFM that works!! past frying its chipset
in an attempt to repair a not very good upgrade...
dont shoot the messenger ... ioh
