    I am thinking of buying my first eprom programmer and wonder if you
    can give some advice. I am currently looking at some used ones. SUch
    1) BP Microsystem EP-1140
    2) Needham EMP-20

    I really don't know much about it yet and just trying to learn as I go
    along. I am only into it as a hobby at this time.

    So of the above two which would you choose? why?

    I am looking to be able to do Eprom, EEProm and to be able to program
    the Lattice 20V8 (PLD??) chip. specifically I also need to be able to
    write the Motorola S-files and odd/even address splitting. What is
    your opinions.

    Buy a BP Microsystem and you won't be sorry ever. But they are very pricey
  3. Also take a look at for the Galep-4. Sells for $333.

    Thanks for your reply. Any idea if the BP 1140 can program PLDs such as the
    Lattice 20V8??
  5. I've never done PLD on one, but according to it does. BTW, what do the BP
    1140s go for used? New they're quite the bux.

    Around $200 used. By the way, according to the the website you
    mentioned above, the EP-1140 will not be able to program Lattice 20V8

    AFAIK the EMP-20 has reached end of life, so look carefully at the
    device list at the Needham's web site to see if the devices you are
    interested in are supported. Assume that those are all that it will ever
    support. That may not turn out to be true but don't bet on new devices.

    The EMP-20 is parallel port driven. Once this was not a problem -- as
    in, who ever heard of a PC without a parallel port? Answer, of course,
    is that a growing percentage don't.

    It also runs strictly DOS software which is fine on Win9X but some later
    Win versions (XP especially) may not work with it (laptops, especially).
    There is a utility on the Needham's site to run the EMP-20 software
    under NT and Win2K -- which has worked on the machines I've needed to
    use it on but I've not tried it on any XP boxes yet.

    As one poster mentioned, the EMP programmers use SIMM-like personality
    modules to route signals to the programming socket. Check whether the
    devices you are interested in are supported by the standard three
    modules included with the programmer. And, make sure that they're
    included in the price.

    Also, even (or maybe particularly) for hobby use, separate EPROMs are
    not used as often as are microcontrollers with on-board flash or EEPROM.
    Don't assume that "someday" you'll need to be able to program EPROMs
    unless you have a present need -- which you may, of course.

    Microcontroller families often have inexpensive, although family
    specific, programmers available. If you're just starting out, take a
    good look at devices which are in-system programmable either via a
    serial bootloader or via JTAG.

    At work we have EMP-20 and EMP-10, and I've a personal EMP-11. The
    EMP-11 is Windows-based, handles S-records, file splitting, and the 20V8
    GAL chips from Lattice and several other vendors. I like 'em and would
    buy one again. Heck, I'd get an EMP-31 if I could find a good enough
    excuse for it...
  8. I didn't see a disclaimer for the 20V8 in the list, though I know
    little about these devices. As others have posted BP Micro makes
    fantastic tools. For $200 I'd jump at one (if it will do what
    you need, obviously), given that it was in working shape. I've
    bought a couple (previous jobs) and have been very impressed with
    BP Micro. Great tools at $2K, even better at a tenth of that.
