The main reason I have never played with them is I
could never find a
Fuse Prom Burner schematic that looked reasonable. I still
would like to
do a TTL computer with fused based proms ( or EEPROM's as modern
substitute )for control logic. I am just finishing up a nice
FPGA design
At one point I considered making an "illustrative project" of building
a pseudo fuse blown PROM out of several inline type fuses -- like are used
in power supplies, for instance.
It would be possible to illustrate not only electronically, but visually,
the way that the ROM works. :) "The black ones are 0s... ;)" (or is that
a 1?)
Anything beyond a size of several bytes would be unmanageable, of course.
I figured you might fit 64 bytes in the size of a VHS tape if you use
small fuses.
