I'm tweaking the code structure to make it easier to specify what ROM images are loaded in flash and how they are enumerated on power-up. Hopefully then just one simple file to edit to specify what images are loaded and where, then build and flash. Programmers can be had for $13~16 USD on eBay or elsewhere.

Anyone have a problem with just a bare board? Dan "twoweims" Simpson has a nice enclosure for the EPROM carrier. I could trim the PCB down a bit to fit the case dimensions for those who want the option for something nicer looking than a big hole in the front of their 71 Smile

I could probably modify the case to fit if I had a sample...
Modify the existing holder with a slot on top for access to the programming header then add a flexible cap to seal the hole during normal use.


I would also like to buy one if/when they are available.
