Reading programming off PLD chips (semi OT)

Hey guys

I have a 600 series Mitsubishi control I'm usnig as a simulator untill I find the machine to go with it.

Long story short I'm hoping to integrate a new pc-side of the control

The PC board (Epson cardPC) is interfaced with a PLD (CPLD?) Chip, lattice ISPLSI 2064 series.

All the mits boards actually have ISP programing ports.

Anyone know if these PLDs cab have the programming read off them? It would be really handy.

Thanks

Random googling suggests that it might be possible, unless the chip security bit is set.

for example.

Thanks, I've just been waiting on a USB converter for this.

Have you been able to accomplish this? I have an equipment like this as well and its using a ispLSI 1048E chip controlling an optical equipment and the legacy hardware has no software available from the manufacturer. I understand that through the RS232 a pc was used with a gui program sending commands and then it retrieving data on to the pc for plotting etc. So I cam trying to figure out how to look into the chip with the program and decipher the commands to create a new program to drive this unit. Maybe one of the softwares from the Lattice website can be used to extract and retrieve the software inside the chip etc. Please let me know if you had any success and what angle of approach you took
