Eprom programmer ?

The one I use and recommend is the one from Andromeda research :

regards Richard Freeman

I got this one working on a few Win2k/XPPro computers using UserPort driver without extra software. As for the unit we had one for years and cannot break it.

Boronia, last time I looked :-)

They only do 12V Vpp chips IIRC. Sometimes one needs to do 21V/25V chips too.

Try this place

then click on "MCU, Programmer", then "universal programmer"

I got the WP38a about 3 months back, runs on USB, which means it will work on almost any modern computer for a long time to come. (where many of the older parallel ports may have problems in the future if and when parallel and serial ports disappear from computers (especially laptops)

works great, have used it with some large PICS, and many eproms from

Also not listed in the specs, it has an inbuilt frequency generator - and an 8 channel logic analyzer buit in (you connect some of the pins from the zif socket to the circuit you want to monitor, using short lengths of hook up wire)

Even though they ship from Hong Kong, it only took about a week from payment to receive it in the mail. (Australia)

Hi ... funny to see a mention of JED on this group.

Yes we are in Boronia. Have been since we started JED part-time in 1977 at home, and then in leased premises in 1985 and our own since 1997 in Boronia Rd.

The PROM programmer only handles 12 to 13 volt PROMs (you have not been able to buy 21v ons since 1992!) see:

You may have seen the AVR CPU board we ran for hobbyists in Si Chip recently as a kit. See:

If you have an Expro programmer, and if you are interested in repairing it, then circuits are available on the Net. There is also a diagnostic "Testpro" program.

Or is it the 386 PC that has died?

Can you post a URL for those please Franc?

Good guess Frank, it was the 386, but guess what I found under 30 years of accumulated boards etc in the shed ? Many thanks for all responses. Cheers Jim

Oops, you're right, Alf.

I have an Expro-60 that I'm keeping alive with an old 486, so I understand your problem.

The one I have runs off the serial port which I think is more likely to be compatible in the future because it doesn't rely on any drivers or software in the computer except for a terminal program. I can't see the serial port disappearing for a *long* time even if it needs to be added as pci card or a usb device. On the other hand a USB programmer's drivers and software might stop functioning on windows 2009.
