That really surprises me. Mine was utterly unusable with the IIGS. The
desktop (and all icons, folders, etc.) had distinct vertical bands through
them. Also, lots of dot-crawl at sharp edges from what I recall.
I rather strongly suspect that there isn't any such thing as a single
GBBS-8200. Rather, the manufacturer is constantly changing the firmware
(if not hardware) and it's a crap shoot as to what particular
ideosyncrasies will be encountered with an individual board.
Has anyone heard talk of the GBBS boards being field flashable?
