I had bit of fun hacking around with one a few years ago:
http://www.vintagemacworld.com/charlie.html
The target market for MacCharlie were people who needed an occasional or part-time PC to run DOS applications such as accounting, database, online services etc. The limited graphics capability meant that it couldn't do much more. The Mac console updates quickly enough to make it usable for text based applications.
Dayna considerably overestimated the market and had a warehouse of unsold MacCharlies and unassembled parts. They worked out that most buyers used the MacCharlie for file transfers and reworked it as the FT100 PC disk unit. This used a MacCharlie case with a serial or SCSI connection to the host Mac. It was a much bigger hit and was followed by the well known DaynaFILE range.
Accessories for the MacCharlie included a carry case (which definitely was sold) and an expansion card for ISA cards (built, but I don't know if it was ever sold). The expansion slot in the MacCharlie is a modified 8 bit ISA slot -- check the pin outs before inserting a card.
Dayna created ROM updates and software updates. The version for the Plus should be good for System 6 and other Macs.
