Ive always wanted to update the software on my ABI Chipmaster as it was outdated when I originally got it. The issue is ABI like to try and extract every last penny from people that own any of their equipment and in order to do any updating then you have to buy their software and that costs A LOT!

Today I opened this thing up and found a 29LV040 chip in there which I obviously was the thing I was after. The device is in a 32 pin PLCC package and is soldered directly to the PCB.
I fired up the how air rework station and removed that chip.

After fitting a socket I downloaded the latest software from the ABI website and reflashed the ROM



Now I have the software file Im going to pull this thing to bits in IDA Pro and see what interesting things I can find, maybe its even possible to fix the Z80 testing function that ABI cant be bothered to fix themselves.
