[Building an EPROM PRogrammer]

Sevearl good reasons

1) You cna probalby build one in less time than it takes to come from
whatever mail-order supply you choose (that's certainly true in the UK)
which means you can get on with the project.

2) Many of the modern cheap programmers need a PC/Windows, which not all
of us have, or care to have

3) Many modern programmers do not support older EPROMs. Heck, some of
them no longer support any Vpp higher than 12.5V. This is a problem if
you want to program those 2732s....


> it's an eductional thing but hanostly can't you find a better way to use

And yes it is an educational project.

> your time than to reinvent the EPROM programmer for the 10,000th time?

Care to suggest some???
