[Coco] 512K EEPROM...or 4MB!!?

[RETRO Innovations]

Though it was not available to demo at the Coco show in 2015, I have on 
my bench a prototype 8MB Flash Cart, offering the following features:

  * it can be programmed by the Coco (1/2/3)
  * It can hide the registers, and unhide them.
  * The base address of the registers can be changed by the Coco
  * It supports mapping any 2kB region of the flash cart into the Coco
    cartridge address space
  * I believe it supports up to 32kB address space, but I am not 100%
    sure I have the logic correct for that (it would work, I just have
    not tested it)
  * It offers 2 momentary switches that can be read under software control
  * It supports a single LED that can be software controlled
  * It fits in a small Coco cartridge case
  * It is licensed under CC3.0 license
  * Can be produced pretty cheaply (under $50 for sure)

Obviously, it lacks a nice programmer utility, which is where the 
project basically stopped.  It's viable and cheap, but does require 
software development to be useful.  I currently do not have the time to 
write such a utility, but I have two units and am happy to send them to 
interested individuals who are capable of writing said applications 
(needs a menu and a programmer app).  I can provide any technical 
support on how to program, but my 6809 ASM and even my Coco BASIC 
prowess is limited.

Not trying to rain on your parade, but thought I should lay my card(s) 
on the table.
