I have a Sunshine (well clone) that will do 22V10s given access to an
MSDOS box with an ISA slot.

But I realised later that a 24 pin DIP version of the 22V10 would be
easier so the part could be removed from a socket on the daughter board
for programming; or even a ZIF socket like the EPROM.

For ease of programming's sake, it may be better to use the Xilinx part
with JTAG port and put a JTAG interface on the daughter board so it can
be reprogrammed in-situ.

And I have a JTAG programmer that is almost finished (as a prototype
anyway) for programming ..
