Honored ContributorHi Pete,
thanks a lot for taking the time to reply. I had not realised that Altera were dropping support for the 7000 series from Quartus, that is useful information. Yes, I realise that the 7128S is very old, and if I needed a device with gauranteed future availability, then I would not consider using it. However, my interest here is in using the device as an introduction into CPLDs and Verilog/VHDL. The project that I have in development is a hobbyist one, I have a basic hardware design using discrete logic that I want to convert to CPLD as an introduction to the topic. Eventually, assuming that my brain can handle it, I will move onto FPGAs, but at this stage, since I have a number of the EPM7128S available, I'm planning to base the design on it. That's probably not a good reason for starting out with such old technology, but in the spirit of walking before I run, I'm comfortable with the decision. The modified board design will include a JTAG interface, but at this stage, it has not been built, so I am looking for a cheap board to start out with. I'm guessing that with simulation, that might not be necessary, but I like to "feel" the hardware. The "grey market" dev board suggestion seems like a good idea - if I knew of where to look to try and find one? regards Dave
