One can also purchase (very inexpensively) 32 pin DIP-to-PLCC
adapters to enable one to use the still-abundant 1 and 2 Mbit Flash
chips used on PC motherboards. Many of these things have boot block
protection, another big plus if you're worried about inadvertently
destroying the contents. The adapter allows them to programmed in
your favorite ZIF-equipped programmer, if you don't want to enable in-
circuit programming.
FWIW,

Hi
I recall looking at one of the early flashes with a boot block and thinking
that the boot block alone could contain a complete Forth interpreter/compiler
with room to spare for things like hardware reset.
