I am looking for a DIY eprom programer for the 27xxx series..
any urls I can look at?

Thanks,
Ryan

I am also interested as I have a bunch of surplus
27C64 - 27C256 devices that I will be using in an
upcoming 'bot design.  (Yes it will use at least
one PIC for motor control, but the brain will be
an HC11).

Software to *do* the proramming would also be nice BO)

There is source code (in Turbo Pascal), and a circuit diagram on my
website, it's under the 'Misc' section. I didn't write it, I found it on
the web somewhere.

A few days ago, I did some searching on the net. That's what I found about
DIY EPROM programmers (for DOS):

http://www.bos.nl/homes/waklos/
A nice prommer from Willem Kloosterhuis which programs:
27C64 ..  27C040/4001
28C65 ..  28C040
28F64 ..  28F040
29F64 ..  29F040
serial eproms
 24C02 .. 24C65
PIC 16C84 and 16F84 microcontroller
PIC 12C508 and 12C509
An impressing list of devices and you can build it totally for free! But
you'll have to make yourself (or by from the author) a doublesided 160mm x
100mm PCB. In the next weeks he wants to release a new PCB revision.

http://www.zws.com/products/epromr2/index.html
A more simple design, to simple to release a pcb layout (that's what the
author thinks about it). It can program:
2764 8192x8 EPROM
27128 16384x8 EPROM
27256 32768x8 EPROM
27512 65536x8 EPROM
27010 131072x8 EPROM
27020 262144x8 EPROM
27040 524288x8 EPROM
831000 131072x8 mask ROM
This programmer is named EPROMr2 and it's free. EPROMr3 should be released in
future, but it won't be free anymore.

And last an URLs of a Link Page you can have a deep look into:
Computer hardware projects at http://fagersta.com/electronics/hwprojects.html

I haven't build or tested any of the designs yet but they might be useful
