I have an old EPROM programmer for the PC. It uses an

EPROM programming. It is a fairly simple device but it doesn't
appear to be
working.
JDR still has the software on their FTP site for the programmer, I
think. I
believe it uses the "MOD-EPROM" software from the "MOD_EPRO.ZIP"
file. It
appears there are several pieces of software on the JDR site which
support
this programmer
Whenever I start the MOD-EPROM software it says it cannot find the
controller board. It is looking for a device a 0x2A0 but
apparently can't
find it. The software does NOT allow the IO address to be changed
and there
are no configuration jumpers on the controller board.
The ISA controller board installed in 486sx (25 MHz) but the
software could
not find it. I tried with a P3 (450 MHz) and got the same result.
Does anyone have one of these EPROM programmers and can lend me a
hand? I
need to confirm some things in order to determine if this part is
working or
not. It may be I am using the wrong software or too fast of a
computer.
I had one of these many, many years ago. If memory serves, it
worked fine in an 8MHz XT clone, but failed in a 16MHz
80286...suggesting bus speed sensitivity. The software not detecting
the board was the exact symptom.
