RE: Still having eprom troubles

Are you SURE that you are using the correct setting? Like I said earlier, I
believe that TI made 2 different flavors of 2532s - "Regular" 2532s and
TMS2532s (which are really pin compatible with 2732s.) The MSB of the
address could well have been one of the pins swapped between the two
versions.

Subject: VECTOR: Still having eprom troubles

Hello all,

I am still having trouble programming my eproms. I thought I had some bad
eproms so I purchased some new ones. Now after many hours of trying all
kinds of things I noticed that each eprom fails the verify check at the
exact same address 0800. The ram contains "01" and the device contains "FF"
on four chips in a row. Does this mean my programmer is dead or does this
mean something else? I am really new at this programming thing, so I could
be doing something very wrong. I do have the correct device selected TI
2532A. I would think that what ever is in ram should write to the chip
whether it is correct or not; for this reason, I don't think it is a file
problem....Correct?

I saw a recent thread on what programmer to buy; I guess I will research
that in the mean while.

Thank you in advance for your input,

Cameron
