Re: Still having eprom troubles (looking for a programmer now)

I should have asked this in the first place; do you have the device list for the programmer? Does it include Texas Instruments TMS2532, TMS2532A, and TMS2516?

  I've got an "Omni 64" programmer that you (or anyone else) can have for postage. It is marked "OAE" which I think stands for Oliver Advanced Engineering. I don't know anything else about it; I bought it on eBay years ago. If anybody on the list knows about this machine, please fill me in. I can take some pics if anyone is interested.
  I'm never going to get involved in programming EPROMs, so this thing is just collecting dust.

  Thank you John,
  It seam so obvious now that you point this out.
  Well I checked all eight sockets and traced the path as far as I could (mutli layered board without schematics) and I only found one solder joint that was questionable. Unfortunatly it did not fix the problem. I tried to call Bytek (makers of the programmer) and there phone has been disconnected.
  So now I am looking to buy a new or "new to me" programmer.
   
  I see people have listed a 29B, 2900/3900, Needhams EMP-20 & 30 as programmers worth looking for, but I seam to be having troubles finding some of these and I am not sure what I sould have to pay for a programmer capible of programming TMS2532's and TMS2516's
  I will keep searching but, in the mean time if any of you would like to give me some pointers that would be great.

  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.

  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
