Palasm?

I've missed part of this thread so I may make some wrong assumptions here
but I'll throw in what I know about this stuff.

    DataI/O has both a software PALASM and a hardware PALASM. I have both
of them and the docs for them. They appear to do the same thing and I don't
what the differences are but there probable are some. I just got this stuff
recently and I haven't had time to learn all the details about it. The
software versions are called Abel and the was available in PCDOS, UNIX and
VAX VMS versions. I have the Abel PC DOS version ($895!) The hardware
PALASM is called a PALASM Design Adapter and is PN 303-100 ($395). It's a
unit that plugs into a DataI/O model 29 programmer and the unit with the
socket for the PAL plugs into it. There are a number is different PAL
socket units. Some of them only work with a few PALs but the one that I
have is a DataI/O model 303A-011 and it seems to work with most PALs. I
also have the manuals for it and the model 29 programmer. I also have a
DataI/O UniPak EPROM socket adapter and LogicPak adapter and I THINK I have
the manuals for them. I also have the manual for the 303A-002 P/T adapter
(one of the PAL sockets) but not the hardware. You MUST have the manuals to
use the DataI/O stuff since the manuals contain the codes that you have to
enter into the programmer in order to tell it what kind of device you're
using. I can make copies of what I have for the cost of copying and postage
if anyone needs them.
