So, Theorically, one could just use the same information and dump the data via an Arduino . The only issue is being when they are registered or partially registered/combinatorial.. -----Original Message----- From: Techtoolslist [mailto:techtoolslist-bounces@flippers.com] On Behalf Of Fabrizio Vasile Sent: Tuesday, March 17, 2015 1:32 PM To: jrr@flippers.com; Technical Tools Mail List Subject: Re: [Techtoolslist] leland off road pal dump needed u85 I use this device to dump protected PLDs (in the project archive there is also the software needed to analyze binary dumps): http://dreamjam.co.uk/emuviews/pal/index.html Il 17/03/2015 17:29, John Robertson ha scritto:
What is the hardware needed? Perhaps it can be duplicated on this side of the pond...

Yes, I have the hardware to dump it.The problem I'm located in Italy and there are chances the chip could get lost during shipping.

It would be nice to get the chip / jed to Fabrizzo to put up on jammarcade pld archive.
He already mentioned he has the hardware to dump them.

I'll forward to Aaron Giles and see if he has the correct stuff to dump these too. I could bring the chip to him.

I can mail you the chip for the track pack.
Otherwise I can use my rom burner to read it, but that may take longer for me to get to.

I might still have the exact adapter. I'll look for it Tuesday and report back here... I can take a few pictures of it. (I might even have a Track Pack boardset and could just read the PROM in here. I don't remember what's our machine in storage. I'll look. If nothing else, if our PCB is the original one just reading and duplicating that would serve as a proof of concept.)
OE&CE can just be disconnected. Looking at the schematics all the outputs are going to be push/pull (no tristate), so nothing 'special' required to brute-force the dump. (Also, two outputs are not even used.)

Do you have a pinout of how you did it Did you go from pin one to pin one Did it matter what address line or data line went to what pin on eprom The 2716 starts at address 7 on pin 1 And data lines are split From side to side What did you do with /oe or /ce Thanks tony
