EPROMs and EEPROMs. I can't justify the cost of the big professional things
costing hundreds of pounds. At the moment I know I will need to program a
27C1024 EPROM (40 pin DIP) and a 28C256 EEPROM (28 pin DIP), but it would be
nice to have something that can handle a reasonable variety of devices.
I believe the Willem programmer may be suitable, it is certainly affordable,
would that fit the bill? It seems to come from Thailand, although there seem
to be all sorts of sources on ebay, so I am not sure what the genuine source
really is.
I made the mistake of purchasing one of those Thai units. Don't waste
your money. Flakey software, scattered documentation, zero support
(doesn't answer e-mails).
I am also not averse to buying secondhand, ebay or
otherwise, if I can get
something that is going to be more generally useful than the Willem.
I highly recommend the Andromeda programmer:
www.arlabs.com
Incredibly well supported and they've been around a while. Best part is
that they provide complete service information and schematics for the
programmer and all adapters. Even better part is they sell bare boards if
you want to build any of the more obscure adapters (I built a bipolar
PROM board for mine).
The base unit handles both devices you mention above - no adapter needed.
