While the EEPROM is busy writing, it will return the complement of the 64th byte; when the result comes back as the actual value, you’ve programmed in that byte is returned and can move on to the next 64 bytes. There are still a few parallel flash chips available in DIP, e. The bios works, buy the at still refuses to employ 1.
– Grassroots ECU Development – Library . 29C
Though replacing the stock ibm one gave me kb functionality, i would like 1. Naw, that would be hokey.
The 29C should work without any socket mods. I hope to inspire some to grad school. Do you think IBM did it right? Perhaps the limited available time could be used more productively with modern hardware.

Actually, it’s abut as you know it uses the early K motherboard. According to the schematic that I have, pin 1 is connected to pin 27 check this with an ohmmeter and labeled A Maybe I could run some wires datashest my programmer TOP to the sockets.
That would be pretty cool, but I would need to be able to select between U18 or U You mean “Flash” ’em in place? Do ya think the 29c will work in place of the 27c?

You could also try Jameco. Specifically, it should be reasonably priced, reliable, easily available and likely to remain so. I don’t think you can do much better than Futurlec http: The code for this is above my abillities right now, but maybe in a year or two or less if I can find the time to get really serious about learning Assembly. Could you let me know why you think a FPGA approach would be better and point me to any educational material?
Ellen Spertus 2 9 Yes, I booted a with it with its ROM chips removed.
Then, you wouldn’t even have to remove the chips from the sockets There must be something more ellegant that wouldn’t need any external hardware. The damned thing still refuses to do 1.
He sells them in quantities of 10 for That’s a you have? Both pin 1’s are already isolated, so that won’t be a problem. It looks datasyeet they are connected to pin 20 CE. But now I can feed it my Everex mfm card so I can get around it. As far as I know, yes it can. The instructions are read by a low-speed TTL computer they build.
Programming is a little tricky–you do it in blocks of 64 bytes and then wait for the programming to be complete by reading the address of the 64th byte written. Are the 28cs pin compatable with the 27cs? I’ll take a look at the schematics and see if anything looks good. I like the Nexys2, personally, and the books by Haskell and Hanna look pretty good for bringing newbies up to speed.
