If you actually put sockets on the board and insert
the fuses
into that,
you could simulate an EPROM/Flash[like] part. ;-) It'd take a while to
"erase & re-write", but hey... ;-)
Exactly what I wanted to do. I thought about setting them flat against
a board and using the small (half-inch long) "glass tube" inline fuses.
If I can get those to smoke the glass dramatically enough when they blow,
it would be easy to replace the blown parts with fresh fuses for a new
program. Not to mention that it may be fun to be able to re-arrange the
fuses ;)

Maybe I missed something important, but rather than installing blown
fuses, couldn't you just.. have an empty socket?

To be able to have an electrically programmable read only memory, rather
than a ROM.
Erasable would not be feasable, other than manual recreation.

Why not use reed relay switches with a hidden magnets behind them,
slighty smoked to look like fuses.

If I can get those to smoke the glass dramatically
enough when they blow,
it would be easy to replace the blown parts with fresh fuses for a new
program. Not to mention that it may be fun to be able to re-arrange the
fuses ;)
How about using circuit breakers?
Then you would have a manually erasable PROM, without further expenditure
each time that you program it.

Why not just use switches to ground with resistor pullups? Then you can see
as well as measure what the effect of opening a fuse would be, without
actually blowing a fuse.
