I have an Advantech PC-UPROG I have not used for a while. As far as I can
tell it is pretty much the same as the current Labtool48 device they make
apart from the interface. The programmer comes with an ISA card that then
connects to the programmer via a cable. As this is a parallel interface
programming is very fast.
Advantch still support this programmer and I have just downloaded the latest
update for it from http://www.aec.com.tw/ - it supports programming a huge
number of EPROMS, Flash, PALs, GALs etc - let me know if you need to check
for a certain chip.
The software that runs the programmer is a DOS program (but is in fact very
similar to the Labtool DOS and Windows programs) but it runs fine under
Win98 here just running in a DOS box.
If you are interested please make me a sensible offer for this - I guess
Labtool 48s are going for something like 800ukp new.
