Re: Still having eprom troubles

It would appear that something is wrong with your programmer. 0800h
is the start of the top 1/2 of the 2532 and if it is not programming
then there is a problem with Address 11 at the Eprom. could be a bad
test socket, bad solder connection to the test socket, Programming
Logic, or???

If the programmer is new I would be talking to the manufacturer.

If it is old then I would suggest you join the Tech Tools List (TTL)
and ask for help there - or simply get another unit.
