SRAM 256k 8bit wide chips.  You don't need to do all this stuff, just use
the 68030 computer (runs minux) and write drivers for that.  I think that
would be easier.

Also, what type of memory

Masproduction: OTP-ROM
many time use: EEPROM

How do you

tell the chip to write instead of read... :)

Could a temporary "ROM" program be copied into the RAM and

Thats all my bootstraper did...

Btw, writing a ROM for a computer is hard.  (very very very hard)  If it
werent' there would be more computers...
