because the server isn't responding fast.
Meantime, my Googling for "willem programmer" produced this page:
http://www.sivava.com/
which describes a commercially available EPROM programmer. Packages
start at US$39. Many adaptors are available, prices $3 - $70. Driver
software appears to be Windows only (9x - XP). The programmer looks
like a single free-standing circuit board, ~9 IC's plus a lot of
sockets including a DIP ZIF socket. USB power, "DB25" data cable (!).
Ah, reading further, there's an AC/DC power adaptor as well, so I
guess you don't need a PC with both USB and Serial.
I think the two pages are talking about the same thing, or at least
different versions of the same thing. I'm not sure about that.
Hope this helps!

New subject: Willem programmers: was -Re: EPROM programming (27c160's)
Supposedly the USB schematics were released at one point (true USB using a
FPGA for programmer logic) but I have yet to find them anywhere.

Also, forget about technical support. He is glad to take your money, but
don't expect any questions or inquiries post-sale to be answered.
Finally, the DC-DC converter used to derive Vpp for 21V EPROMs is
underdesigned and unlikely to yield reliable results. There was a mod kit
available from one of the Willem forum regulars that I ended up
installing.
All in all, the Sivava was more trouble than it was worth. There are eBay
folks selling "genuine" (i.e. unmodified) Willem designs for less money.

It claims to be able to program GALs as well as (E)EPROMs and there's
a 16-bit adapter for it. The price is very attractive.

I have been programming eproms with one for an N8VEM z-80 board, and also
for some door controller devices :), and have blanked some GAL chips with
it, but I have yet to actually program something into a GAL with it.
It is definitely less painful to get cabled up than my Xtronics pocket
programmer.

In any case, EPROM programming is not the problem. Most EPROM programming
specs are published, and certianly for 'classic' EPROMs, the ones from
differnent manufacturers progam the same way. It's the PALs/GALs/
PLDs/fuse PROMs that are the big problem..

Are you sure it's serial? Without seing it, and without knowing what the
ICs are, I can't really make a sensible comment, but I would have thought
it was easier to use the parallel port for something like this

Maybe not the product, but surely the information
The link I sent you has the schematic and sources of the software used
with the programmer. It is an easy to build programmer, which uses the
parallel port for comms and has some timmings configured and executed in
hardware, so it is easy to adapt to anything that has a parallel port. Maybe
you could use the info and adapt the software (which is tailored for
windows, but has all the info how to drive the programmer) to run in a vax
or anything you feel like :o)
