I've done that lots, but there was one case where I was very, very
happy to have an EPROM emulator... it was embedded firmware for a
VAXBI peripheral card we were making (COMBOARD-BI). By being able to
update the firmware over a serial port and not have to shut down the
machine to swap out the chips, I was able to test a new version of
code in under two minutes vs a 20-minute shutdown, power-off,
power-on, boot cycle.
For normal, table-top sorts of projects, though, real EPROMs aren't so
bad if you have 4-5 sets.
