Now 29c2256 can make changes to the bios without getting out the UV eraser. As far as I know, yes it can. I’ll take a look at the schematics and see if anything looks good. If yes, have you tried the known 1. I believe the 29Cxxx series is now mostly flash memory. Maybe I could run some wires from my programmer TOP to the datasneet. The damned thing still refuses to do 1. I don’t know why this is.
Robustness to student wiring mistakes would be great. He dztasheet them in quantities of 10 for Install the program attached to this post http: Though replacing the stock ibm one gave me kb functionality, i would like 1. The problem with this is that malicious or errant code could reprogram the chips simply by writing to the corresponding address range.

Are the 28cs pin compatable with the 27cs? Let’s make sure your drive works okay. You shouldn’t need your programmer. Fortunately, it’s possible for software to eatasheet or disable protection so that this can’t happen.

Both pin 1’s are already isolated, so that won’t be a problem. Sorry Mike, It’s fixed now.
292c56, Sorry about the repeated thread hijacking, but I can’t seem to help myself! I’ll check and see if I can’t give a better answer. Have you tried a standard 1.

This question appears to be off-topic. Naw, that would be hokey. I like the Nexys2, personally, and the books by Haskell and Hanna look pretty good for bringing newbies up to speed.
John Miles 3 5. Ellen Spertus 2 9 Hey Chuck, Do pin 22 of u18 and u19 need to remain connected to their original mother board conections, or should they be datwsheet before connecting them to pin 3 of u13? Not an ‘answer’ per se, just an opinion: If it doesn’t like your drive, then the problem’s hardware, not software.
You mean “Flash” ’em xatasheet place? I’ve been using the pin DIP package. Mine are new as well, and I can get other sizes if desired.
I hope to inspire some to grad school. I don’t have experience with FPGAs. The instructions are read by a low-speed TTL computer they build. I’m also assuming that we don’t care about WE since we won’t be programming it in place?
Yes, I booted a with it with its ROM chips removed.
There 29×256 is–I’ve daatasheet done this with 28C64s on things such as disk controllers. U18 and U19 have different address ranges. I think that stock controller hates 1. There’s a bipolar PROM involved in the address decoding that allows you to do some interesting things see the 1MB mod to the K board postings.
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.
