- #6: Apple IIe Workstation Card Anomalies
-
- Written by: Dan Strnad July 1989
-
- This Technical Note describes known anomalies when using the Apple IIe
- Workstation Card.
- _____________________________________________________________________________
-
- o Pascal Protocol Serial STATUS call returns incorrect results.
- When using the Workstation card, the Pascal STATUS call (normally
- used for printing) does not properly indicate whether the card is
- ready to receive characters. Applications should avoid this call, as
- the Pascal WRITE call in the firmware will perform this function
- automatically.
-
- o ProDOS 8 invisible bit is not respected.
- The invisible bit in the ProDOS 8 access byte was defined after the
- release of the Apple IIe Workstation Card, so the ProDOS Filing
- Interface present on the card treats this bit as reserved.
