    As a replacement for the EPM7032S/7096S/7128S there is the current series ATF15xx from Atmel/Microchip.

    They are drop in functionally compatible, and can use the same .POF file you generate for the Altera part via a translator program (POF2JED).

    You need a new USB JTAG programmer from Atmel to program the parts with their JEDEC (text based) files.

    But other than that overhead, I have successfully converted an number of legacy EPM7032S/7064S parts in PLCC44 from the existing Altera .POF files. YMMV of course.

    So if you really need something like the EPM7nnnS series parts with 5.0V/3.3V compatibility I find the ATF15xx series very useful.

    Mouser, DigiKey, etc stock these parts off the shelf.

There are two versions of each Atmel part, an ATF150xAS series, which has 5V Vcc and 3.3V or 5V Vccio capability, just like EPM7xxxS.
Or the ATF150xASV series, which has 3.3V Vcc/Vccio operation, like the EPM3xxx series.
