Frequent ContributorQuartusII 13.0sp1 is the oldest version of Quartus available from Intel via their download page.
Earlier versions are not available from Intel without going thru an NDA process.
That being said, I'm not sure any version of Quartus ever supported reading the EPM7K/EPM3K program memory.
I seem to recall that it was only ever supported in the prior MaxPlusII software that supported those devices.
And that software is even harder to find and run (ie, requires early Windows versions).
New ContributorIf I find the MAXPlus II and can run it, can I read the data inside this chip? Can I connect MAXPlus II to the chip via USB Blaster?
Frequent ContributorI checked the documentation inside the MaxPlusII v10.23 (last version or so before Quartus) and it mentions supporting the MAX7000 and MAX9000 series but no mention of MAX3000 series. That came later in Quartus I believe.
Also no mention if USB Blaster in MaxPlusII. Only the old Altera Programming Unit (APU) and ByteBlaster (an LPT port device that was the precursor to the USB Blaster) are mentioned.
So it would appear the answer is no to both of those questions.
New ContributorThank you for doing your research. What do you recommend?
Frequent ContributorI believe the only possible way to recover the bit image file from that device is using a Xeltek IS01 programmer.
But it may or may not work.
If the security bit is set in the device there is no way to recover/read the programming file.
You can only erase and reprogram the device.
It is not 100% certain even the IS01 will be able to read the program out of that device without further research.
Personally unless you have lots of money and time to spend on this I would classify it as a dead end project.
