Very neat !

I personally use a homemade JTAG cable for MAX7000S and other Altera parts that have JTAG, but the JTAG-less vanilla MAX7000 I program with a TopMaxII. If I had one of these things that you do, I would be using it for sure hahaha

With that setup, can you unlock the JTAG pins on MAX7000S? I got 10x 7032s a while back and nine of them did not respond via JTAG...

obligatory 7000 thread https://www.eevblog.com/forum/fpga/prog ... 0-devices/ people tried collecting info about unlocking S parts there, but afair still no success

I've always been interested in the old ALTERA software, but never managed to get my hands on a copy. Is there a "schematic capture" mode (where you can design using 74xx style logic) or a floorplanner style mode where you can view/edit the placement and routing? The 7000 series were quite small by modern standards so I'm interested in what the design workflow was like. Aren't the Atmel ATF15xx series more or less identical to the 7000? Would be really neat to design circuits with the vintage software and then program it on the Atmel devices.

I've received some EPM7064SLC's that had a different Device ID ALTERA96 (00) rather than the common ALTERA97 (01), which seem to be engineering samples for laboratory use, which the LP6 and adapter would program.

The LP6 and adapter should not have issues reenabling the JTAG pins for use as long as they aren't some strange engineering device. I've not purposefully locked any of my EPM7032S/EPM7064S/EPM7128S devices to test, but I plan to perform that, soon.

A person can use ALTERA programs to create a POF then use POF2JED (Windows only at this time) then use an Atmel programmer for the ATF150X series. There may be some weirdness in the JED, so may need some work, but it can be done.

I had some questionable EPM7128S devices, but sent to plasmo a while back for investigation. Some say a resistor and certain voltage and all that. Never have seen it work here. Deep in some thread, someone asked Altera/Intel how to unlock one, and the response was an NDA was provided then and that was the end of that thread.

Also, meaning the JTAG ports for the S devices are used, ya need the old gear, too, to free them (Listen to Donald in the aforementioned URL).

If you find an LP6 ISA card, grab it.

PL-ASAP2 works with the LP6 ISA card.

The other option, which I've not seen, is the PL-APU which is USB. 🤤

Both mentioned here https://cdrdv2-public.intel.com/654917/dspghd.pdf

The adapters I've acquired, which can help the community include the following:

PLED910 PLEJ464 PLED503A PLED5032A PLEG5130A PLED5016A PLED5016A PLEJ810 PLMJ5192 PLMJ7000-84 PLMJ7032 (good for 64, too) PLE3-12A EP600 EP900 PLED448 PLMJ1213

If need anything examined, cleared, checked whatever, or if you find an adapter, send my way to help the community.

Hey everyone, I've been lurking for a little while and I figured it was time for me to join.

I recently became interested in programming CPLD's handle the conversion of data originally intended to go to proprietary DACs. Outputting i2s in the process.

I've successfully handled that aspect of my project but now in the wake of all of that I've ended up with a few CPLD's I'm unable to program.
7 EPM7128ELC84-815
1 EPM7160ELC84-15

I learned a bit later that these do not have JTAG and I had impatiently ordered them prior to realizing I cannot program them very easily.

I was curious if it were possible to hack together some sort of parallel programmer or if I should just give up.

I was very surprised when I learned only the S series had JTAG and I guess I had to eventually learn to fully read datasheets prior to spending money haha.

Nobody has yet figured out how the parallel programming method works. It is in my todo list to see what goes on when my (friend's) TopMax II is doing the programming operations but it has been a low priority, especially since my non-JTAG chips are slowly running out and any "new" ones replacing them are gonna be JTAG capable.
