XC9500XL devices are 5V tolerant and pins can be configured for LVTTL. As output the LVTTL levels are enough to drive 5V logic TTL devices while the input of the CPLD is 5v tolerant. It can be used for the old 8 bit projects just make sure the CPLD gets proper Vcc (3.3v).

Well, I know Xilinx has 5V tolerant parts still in production, but I don't think either offer 5V logic anymore.

    What do you guys use for developing your CPLDs and FPGAs? Do you use the supplier provided tools or some free / GNU positions worth having a closer look at?

  I am working with Atmel CPLDs so I use their WinCUPL software which is
  free. However, I am getting more and more tired of the bugs in it so I
  am contemplating switching to Xilinx or Altera if they still have 5V
  parts available.
