Can Pocket Programer be used for the 29C256s?. I have version 3.55 and don't see it listed. Any clues if it's just software, or hardware?. Weren't they taken over by a new firm, anyone have a phone number, and contact off hand?.
TIA

 

Yes. Many of us here are using the AT29C256 chips with the PP. Its a software issue. You'll need to pay them to upgrade to the latest software IF you don't have the AT29C256 option available. However, with the DOS version you have to press ANOTHER key on the EPROM list to get ANOTHER list of PROMs. ALSO, EPROM.exe does not do EEPROMs. Only FILEPROM.exe does EEPROMs. The windows version of their software also does the EEPROMs.

As Tim said, use FILEPROM, then select "F" for Flash and then option "8" for the AT29C256. I too have version 3.55.

 

I am using ver 1.13 for windoze and it has a date of ( 12 June 2001 ), it programs the AT29C256-90PC perfectly, not a problem at all.

OK, got that covered now,
now,
How do you actually erase them?.
TIA

 

With my old Toshiba, and FILEPROM 3.55, I found that "initializing" with a BIN of Hex FFs first and then I could program the BIN I intended on it.

Without the Hex FFs first, the PP would program it fine, but my ECM didn't like it. With the Windows Version, this "initializing" with Hex FFs is not necessary. Just load the new BIN right on top of the old one and all is fine. Unfortunately, my ol' Toshiba does not like the Windows Version. The Compaq is fine.

 

So erasing it just means programming it with all FFs?
Yes, I'm limited to using the DOS program.

 

Yes. After loading it with Hex FFs, it should check out as "blank". I believe this is just a querk of version 3.55. I've been told that you don't have to do this with 3.60, but I cannot confirm as I do not have that version.

 

From my experiences, You don't HAVE to blank the flash chip with FF's. I do it sometimes just so i can convince myself its blank and so that i can use the cool blank check option on the flashprom.exe
Best thing to do, just program the chip, then do a check on it with option number 3.

I have never blanked the chip first.

Tim, is that with FILEPROM Version 3.55? I know the Windows Version does not. It seems only to be an issue with FILEPROM V3.55 with my setup. And ONLY when I use the Flash Prom in the ECM; reads fine, just my ECM doesn't like it.

 

Glenn,

Just the WinDoze version.

I DO LIKE the Windows Version very much. I just wish I could get it to work properly on my Toshiba.

Guess I COULD buy another notebook. (Thunk ... as the wife hits me with a frying pan).

 

ROFL at that frying pan comment
