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

I had a typo there.. Current boards are "512K" not "MB"

Today I was looking at EEPROM chips and stumbled upon a 4MB chip that meets all the criteria for what I could consider to be a candidate for a EEPROM board.  My current boards support up to 512MB via PLCC32 or DIP32 socket but the 4MB would require some creative adapting with its TSOP40 layout.  In order to make practical, I could design a tiny adapter board to solder it to, giving it legs so to speak, that could be plugged into the EEPROM board or a special adapter for programmers such as the TL866 or GQ-4X.  I'm wondering though if this is 'too much'.  We can fit quiet a lot of
.ROM/.CCC/.BIN stuff in the 512K chips already, but 8 times as much?   Then
again.is there such a thing as too much space?

 

I've got a itch to persue this and see if I can make some sort of 'Mega-Flash' version of the EEPROM boards around this chip.  I could even keep the existing External Controller interface.  Because it uses serial
address control, no changes would have to be made there.   I'm just not sure
if I could even find enough games and utilities in .BIN/.ROM/.CCC format to even fill such a chip.

 

Thoughts anyone?
