Casio FX-602P Ram Upgrade looking for srams
In the 80ies i upgraded the ram of my FX-602P, i added srams and a DIPswitch to manage 5 blocks of additional 512 programsteps each.
My bankswitching does not work anymore, so i decided to build it new. But the static rams D444G/C are not available anymore (since 30 years I think). Is there someone who has this chips laying around? :-) You can find the description on the net, but it is a poor scan and in German. I added it to this thread. Ralf /41/48/ |
