Ed, thanks for the video. That box show what seems to be a customized EPROM simulator. Guys behind it specialize on car chip tuning

Besides being rather expensive, my fear are that drivers and software will soon turn and bite us.
Back in the 70/80’ stuff like this had parallel or serial interface and where very popular (and crazy expensive) among firmware developers of the day.
My initial plan where to use an Arduino developer board containing a Micro SD card slot together with a memory chip. But investigating this further I learned it takes some trickery to interface the parallel memory chip (the part that takes the EPROM’s place) and the serial storage on the SD card. Some rare custom chips are still around to simplify design. But then wanting to do 5 of them got me a little reluctant J
There is also that idea that limitation is what trigger the creative part of our brain. If my SDS7 had access to my computer I now suddenly spend my days browsing thousands of drum samples, that I already are not using J
I’ve stated a simple 2 sounds on a single EPROM documentation for those interested in DIY. This will be nondestructive to your SDS7.
Please be patient with me, but don’t hesitate to correct me or give me directions.
