Just for curiosity i got hold of an 8051ah from Intel.
I have a T48 programmer.
I tried to use all the variants of P87c51 listed in the available chips for the programmer software XGECU.
The software for each of the varients (FA,FB,FC,RA,RB,RC,U) all warn me to click off the check id. I guess this is beacuse the check id may not match 87c51 when i am programming a 8051.
Anyway
They all fail to program
Thay all read fine and return no errors with FF.
I downloaded the
Acorn_0280,022-01_KBC_ROM.zip
(3.51 KiB) Downloaded 113 times
file and am using that as the file to be programmed.
Am i wasting my time ?
