  1. Haven't seen that one before, but the problem is the same with all these
    cheap universal programmers - the software support (now and future).
    It can be a lucky-dip as to what will work and what won't, and the makers
    seem to drop support for these cheap universal prorgammers pretty quickly
    Programing EPROMs and the like are usually not a problem as they are fairly
    generic and tolerant of the algorithm used.
    However, I wouldn't trust such a device to program the myriad of PIC or
    Atmel micro's available for example.

    What do you need it for?

    Indeed. Many of them used parallel ports (with some even using
    proprietary ISA cards) as the PC interface and all timing was done in
    software. That worked in DOS, not so well in the NT versions of
    Windows. Not knowing that particular programmer, I'd give it a 10%
    chance of working today.
    Does anyone use EPROMs anymore?
  3. I just resurrected an ancient Toshiba laptop (windows 95, 16MB RAM) for
    just this purpose (parallel port EPROM programmer). Ran off 100 EPROMS
    for what is hopefully a "last time build" of one of our older
    boards. It's all packed away in a box now, "just in case".
    In-circuit programming via JTAG now (or similar). The pods are cheap
    too, no more ~$1k device programmers for me!

  5. At $75 that doesn't matter too much

  6. If it's just a one-off then it's probably cheaper to use a programming
    service. Quite a few suppliers and individuals offer this.
