I'm using the EEPROM for the CPU micro-code I'm building!!!

I want this to be a stand alone project- no hookups off
a PC printer port.What I really need is a PROM programer but I have
not even heard of them since EEPROM's have come out.
I made a *touch tone* phone years ago with a *dial* on
it.
(Amusing to see the reactions from people using it. :> )
I you expect to just use octal for data entry, the same
scheme could apply (imagine a classic 500/2500 series
station set with a ZIF socket up under the handset
cradle and a small LED display above the dial... :> )
Definitely a geek conversation piece!

Why does low cost development software - schematic layout
and PCB development and prom/eprom burners mean 1000's
of $$$.
