I'd love to come across any internals information
on the 1510A...
sounds like something easy to adapt to become a hand-held ASCII
terminal
It should all be possible at a software level.
If the right person had a vanilla enough ROM for one, we'd all be set
just by copying it.
BTW the 'big head' on this one is just the scnner part, and is removeable,
at least with mine.
