[Coco] Ultimate Eprom/Flash Paks Have Been Designed

[Kip Koon]

Hi Guys!
More Info!  The 8-bit register currently sits at $FF40-$FF5F to keep the
chip count down.  This first version is primarily for those who want to put
all their rom paks and .bin files <16KB in size online with no drives of any
kind.  These first PCBs will just fit into a game cartridge if I have done
my homework correctly.  
No menu system has been written yet so execute the following command line to
change banks.
POKE 113,0:POKE $FF40,BK
BK = the bank number from 0 to 63 for the Eprom Pak and 0 - 31 for the Flash
Pak then press the reset button.
As I can program DIPs already and need to figure out how program PLCC32
Flash chips, I will build the eprom version first once the schematic has
been approved.  I have seen PLCC32 to DIP32 adapters on ebay.  Does anybody
know if any of them will work on the Willem Eprom Programmer?   Take care my
friends.

Hi Guys!

I have finished version 1 of the schematics for an Ultimate 1MByte Eprom Pak
and an Ultimate 512Kbyte Flash Pak.  The Eprom pak will hold 64 - 16KB ROM
Images and the flash pak will hold 32 - 16KB ROM Images.  Would any
electronic engineers like to double check my schematic?  Once approved I
will ask for testers for the first PCBs.  After the design is fully
functional, then production units will be made.  Any takers to help me out
with checking everything over?
