Re: [emax] emax parts for sale

Frank-

I am aware that PAL "R" (registered) are not broken.
I am also aware that currently the only method to reverse engineer requires an electron microscope to view the gate matrix and create a reverse map.

I have been given the original EMU binaries, but they are in a proprietary format which I haven't yet converted to JED.
Jedutil doesn't work and I haven't had time to run them through the paces of all the other available utilities as of yet.

The binaries I have been given are:
IP430
IP431
IP432
IP437
IP439
IP440

Assuming I get them converted, I will then burn PALs for nominal fee to anyone who might want them, as I have a programmer and original MMI PAL16R4 ICs.

Regards,
Ted

Hi Ted,

Which PAL's are you referring to? To my knowledge it isn't possible yet to "read" (for example the PAL16R4(ANC) located at IC25 or the PAL16R6 located at IC26 of the Emax II main board) PAL because they were 1 time programmable with a factory burned fuse that prevents to read the prom. Also it is very, very difficult of re engineering the prom through the "scattered" data it will generate if prom is accessed back works.

Frank
