Usually the low end programmers depend heavily on programming timing in
software, which is not a good idea on a multitasking system.
If the delay loop is calculated for 25 ms and the OS does something else in the
middle for 500 ms, the EPROM will get _well programmed_. It often works, but
you are far outside the EPROMs specs.
In case of Needham, they require a special device driver for NT which bypasses
task switching (or disables interrupts) during programming.
It is quite easy to write a similar driver for Linux, but there have to be a
different one for each programmer.
I am looing for a programmer you connect serially. I have an old one, EPP2, from
ART in The Nederlands, which I have written a Linux program for. It works well
even on a lap top. (It takes 29F040 :-)
But the unit is quit obsolete, and the company seems to have disappeared.
