[Coco] FlashPak

Hi Jim

Do you plan to offer any pre built FlashPaks for sale?   I would love to try one and see what kind of software menu I can come up with for it. This sounds like a great coco tool

I finally was able to validate that my simple Color Computer FLASH ROM
cartridge works!

<https://github.com/go4retro/FlashPak/>

It's a 512kB ROM cartridge that uses the CoCo standard banking mechanism
to select 1 of 32 16kB ROM "banks". The unit can be programmed while
installed in the CoCo, meaning no need to own an EPROM programmer or
eraser or another computer to program the ROM.  The PCB is through hole,
so it can be assembled without special tools.  I have more work to do,
as it needs a proper menu and programming app (the BASIC one I wrote to
test works, but is very slow), but at least I know the design works!

Jim
