These were assembled by MACRO in DOS-11.
To load the sources, attach the files to the paper tape reader. In
DOS-11, type "R PIP" and then "DK0:SPACE.MAC<PR:" etc. Type ^C and
then KI to kill PIP.
Next, type "R MACRO" to start the assembler. Assemble the game with
"DK0:,DK0:<GTMAC,IFMAC,SPACE" and similarly for GTROS. Type ^C and
then KI to kill MACRO.
Finally "R PIP" again, and save the binaries with "PP:<DK0:SPACE.BIN"
and similar for GTROS.BIN.
The binaries have been converted to PALX format.
