Re: EPROM Programmer

Thanks for all the replies, I'm wondering from Rich's reply that if
I breadboard the EPROM for reading, and hook up a 4-bit binary
counter to the inputs at say 1 herz, then whatever is programmed
(binarily speaking) at address zero will fire corresponding
output pins (the one's, not zeroes), and a second later fire output
pins corresponding to data programmed in address one, toggling
each second through to address 15. I could program one's and
zeroes in the proper spots at each address to control a segmented
LED to change character every second. If not enough milliamps
for LED's then I could incorporate transistors at each output pin
to fire the LED's?
Am I thinking correctly on this? Hope so as this could open
up a whole new area for me.
Any responses appreciated,
Bart
