This past weekend, Trixter — a self-proclaimed IBM PC historian — picked up some old software for his archive. What he didn't count on was a couple of additional Avantage titles that had never been released into the wild. If this weren't enough of a find, one of these titles provided Trixter with an interesting puzzle: the diskette for Mental Blocks
is apparently hand-formatted to work on both C64 and IBM
(on a single side, not the "flippy disks" of old). Quite an interesting little piece of history.
