The card has a non-standard 26-pin triple-row DB-type connector that
pokes out the rear of the LC family cpu. There is a specific cable that
attaches and "Y" connects to two different external devices. One leg
has the 19 pin female and attaches to a suitable disk drive. The
Unidisk 5.25" would be a good bet. The other leg has a DB-9 female
and attaches to a standard Apple II or IBM converted joystick.

Well there is a glimmer they do know something. If you go to
ftp.dayna.com, there is a Daynafile directory listing. From the
accompanying readme:

"DAYNAFILE READ ME

These files are for use with the DaynaFILE and non-PCI based Macintosh
machines. Beware that these files are PASSWORD PROTECTED. Version 3.1
of the software is free of charge, and requires no ROM upgrade.
Version 4.1 is not free of charge and requires a ROM upgrade.

For information on passwords or ROM upgrades, please contact:
