I have a project in mind using small Flash RAM and a cheap CPU to substitute for the old TTL level CMOS RAM used on arcade games.
This has come up because the NVRAM that is currently being used is getting hard to find at prices under $7 to $9USD.
Something like the M25P05-AVMN6P (512k or 64K x 8) or similar chips are $0.20 in single quantities.
The size of CMOS RAM we are replacing ranges from 512 x 4 (yeah, 512 bits) up to 256K x 8 (perhaps the AT25SF041B-SHB-T?).
Granted this will take a bit of programming but I don't know if it is possible to start with before I want to invest any time/money into this project. I mean we can use batteries until the current shortage in NVRAM is over, but that isn't as much fun.
Also, we need to get past the doom & gloom crap I'm seeing here.
