Am I the only one that would like such product?

One of my early boards was a flashable cartridge. It was to be programmed by Arduino & shift registers. I moved on to DFB1 and left it behind before I'd got the bugs out.

If I were to do it now it'd be jumper/dip-switch based and try for the read/write approach.

If CPLDs were still under a fiver, it'd be a fairly trivial design.





BTW, on the original subject in question, I did a video a couple of weeks back about exactly this subject: dualtos with HN27C4096s:




Cheers,

I am hearing that we might not be that far from the end of the chip shortage. If you come back to this and are looking for a buyer or tester, let me know :)

Thanks for the video!
