Where can I find a description of what all the hex digits represent in a GROB
definition?  I know they represent some kind of bit pattern, but I can't
figure out how it's organized.

Also, a while back I saw a posting for a do-it-yourself serial cable that used
a hacked up DIP socket for the HP serial connector (I know, the spacing of the
holes is incorrect, but apparently there is no harm in using .1" spacing, you
just bend the HP pins slightly).  I found an easier way was to buy a SIP socket
(20-pin version is $1.50 at Radio Shack), and use diagonal cutters to lop off
a 4 pin section for my cable.  That piece, along with a 25 conductor ribbon
cable w/o connectors, and a DB25 press-on connector ($10.00 total) did the
trick.  Just a little soldering and 30 minutes labor.  Now I can FINALLY
download CHIP48, BRIX, PONG, Saturn Assembler, Tetris, HIDE, .............
Well, you get the idea!  :-)

A happy camper,
