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 ?
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)
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.
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.
