Does anybody out there have any experience with the Convergent 
Workslate laptop (this is a machine that was introduced in late
1983-early 1984 and basically was built around a spreadsheet
program.  It includes microcassette storage (both voice and data)
and telephone capabilities (modem as well as speakerphone)?

In particular, the machine at the liquidation prices these days
($100-$200 with business application software) looks quite
attractive - for the price of the Sharp Wizard or not much more
than a high end HP financial calculator I get a spreadsheet
computer (I don't need it for writing - I've got another early
laptop, the NEC PC-8201 if I want to type).  However, the
machine needed/needs an optional I/O box for regular Centronics
printer output and R/S 232 serial I/O.  I'd really like the
RS 232 to dump data to a full sized computer.  I assume that
since the Workslate can print to it's own proprietary printer
and has a built in modem it has most of the hardware already
available for I/O.  Anyone out there able able to point me in
the direction of reproducing the option I/O box?

Thanks in advance for any info!
