Seems Jens is not a popular guy around here!
I wonder if someone would sell an "upgrade kit" with a RAM chip and the 3 capacitors? Optionally a mail-in solder service. I am sure it would be a success, assuming Jens does not cripple on purpose upgraded cards with a new firmware update!
note: Kipper's card uses
Infineon HYB5118160BSJ-60 = 1M x 16 Bit 5 V 60 ns FPM DRAM
but the standard ACA RAM is nearly identical in spec, except it is EDO and not FPM.
FYI, standard ACA500 2MB ram chip costs less than $3 !
