The Worktation card is identified by the low-ASCII letters ATLK at $CnF9. Immediately following is type ID which is as follows:
| Type | Firmware |
|---|---|
| $00 | Apple IIgs |
| $01 | Apple //e Workstation Card |
| $02 | Apple //e Server card1) |
| $F0 | Card diagnostics are running |
| $FF | Card diagnostics have failed |
The FIConvertTime call is buggy and can return a ProDOS time that is up to a few minutes incorrect. The IIgs works perfectly.
