If you're talking about eprom emulators, "back in the day" I used to
use a device called a "PROMICE".

It was wonderful.  I did a few different boot proms with one. Very handy.
It was made by (I think) Grammer Engine.  Try www.promice.com.  But
gosh, they do seem more expensive now that I remember...

I looked on ebay and didn't find one, sadly;  I did find, however an
"ostrich 2.0" USB eprom emulator which looks nice.  www.moates.net

Apparently there is a large community of people out there hacking engine
ECU's.  who knew? :-)
