I recently bought a "Willem" programmer off Ebay for about $50. I've been
using it for 2764s and 27256s. It does a lot of different ROMs including (I
think) 2708s. It beats the crap out of my old, tempermental, PIA, Prolog
programmer :-)
Highly recommended.
See ya, SteveRob

Subject: 2708 EPROM progreammer - old magazines designs
Hi,
I am thinking of building a programmer for the 2708 EPROM, that can also
read an EPROM and dump it to a serial port.
As 2708s are obsolete few moern programmers support them, apart from a few
that cost many $100s. So I thought why not try and build one? I've found
references to the following classic magazines, and I would be willing to
pay
a small fee for photocopies or scans of the articles:
Program your next EROM in BASIC. Schematic for a 2708 erasable read only
memory reader and programmer which uses parallel IO ports to set data and
address. The software to drive the programmer is written in BASIC.
Byte - March 1978 page 84 on (main article)
Byte - April 1978 page 62 (Byte Bugs)
How to program 2708 EPROM's using this circuit board and program.
Byte - April 1980 page 198 on (main article)
Byte - September 1980 page 321 (follow-on)
A Simple 2708 EPROM Programmer ... For the Motorola D2 kit ... Frank W.
Summers.
Kilobaud - February 1980, page 138 (magazine is currently on eBay)
#638 2708 EPROM programmer.
Electronics Today International (ETI) - July 1978
Instead of money I can provide (or copy / scan articles) any of 24 issues
of
Byte from 1981 to 1997 (including 11 issues from 1986)
which I don't want
to
keep. or I can photocopy / scan articles from nearly
any copy of Practical
Computing from 1978 to 1985 (which I do want to keep).
If you have built your own design of 2708 programmer and want to share
that
would be great too.
Thanks,
John
