    From time to time I have the need to program some of the old 27512 and 27256
    eproms. I've been using an old Sunshine programmer on a very old 386 puter
    that has finally died.
    I note Futurelec have a programmer that works on Win98.
    Does anyone know where I can buy a reasonably priced one that will work with
    the XP operating system ?

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

    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
    2732 up to 27010 varieties with no problems. Also have used with
    some Dallas Rams too.

    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:

    Ed Shoell out at JED Microcomputers ( in beautiful
    downton Bayswater sells his own Aussie made parallel port device, that is
    easy to use and works with XP (with an additional program). Comes bundled
    with some useful utilities. I've bought a few of these over the years for
    various employers/clients.

    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.

    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.
