I may be in the market for an e-prom programmer soon. I've never operated
one before, so I don't know everything that is involved, but I'm looking
for something that I can use to first read the ROMs and then copy them.
Something with a PC interface and software would be nice too. What's the
price range on these units? I've never even priced them.

Where can you get the 4 volume set? I'd like to have a set, I've
always
admired his work.

My guess would be luck. For example a couple months ago I picked up his
"Build Your own Z80 Computer" at the local GoodWill for a couple bucks.
Unless it's misfiled somewhere, the best bookstore that I'm aware of for
this kind of stuff doesn't have any of these.

Also, don't forget that _Circuit Cellar INK_ is
still being published.
Check out (where else?) http://www.circuitcellar.com/
I've picked up a couple of
issues in the past few months, it's an
interesting magazine, but mostly aimed towards embedded computer
systems(who doesn't wany a 386dx with 8MB RAM, built in interfaces for just
about anything and DOS 6.22 in ROM?). Lots of info on those funny embedded
systems and fun stuff like the PICs and BASIC stamps.

I bought one (that uses an interface card) attached to a Columbia

I had completely forgotten about having that Columbia until you asked
about the programmer. Anyone know much about this computer? I've never
used it for anything but EPROM programming, it boots and loads the
programming program automatically.

i've got an old columbia as well. worked with them quite a bit when they
first came out. even have an old tech. ref. somewhere.
as i recall columbia computer products saw a market opportunity when IBM
first came out with the XT. IBM couldn't keep up with demand and columbia
came out with an XT clone and they were selling them like hotcakes for a
while.
soon they lost their competitive edge to the herds of clone makers but for
a while they were quite the rising star in the young PC clone industry.

As long as we're talking about EPROM's, does anyone have info(connector
pinouts, software, manuals) for the CST Triple Crown 700? I picked one up
for $2 at a swap meet earlier this month but he didn't have the interface
card or software.
