I got version #9 of the Altera software to go with the old DE1 FPGA 
card.I have that card so I can do TTL logic macro's and test before
I do a PCB layout using 74LS chips. More modern software seems to have
dropped that funtionality. I also like programing in AHDL because
I find VHDL and VERLOG too confusing to use.
AHDL also has a similar format to WINCUPL that I use for 22V10
programing. This way I can define logic modules using 22V10's
with the FPGA and test that as well as the 2901 emulation.

Any PCB designs I build will use through the hole parts, thus 22V10's 
will be my biggest programable device.
