|HP-IL floppy disk commands ?|
Message #1 Posted by Pavel Korensky on 9 Dec 2003, 12:58 p.m.
anyone have the listing of DDT/DDL HP-IL commands for HP9114 floppy disk ?
I am not able to find them in any available documentation.
I especially need the description od bits in Status byte.
Also, I need to know what commands behave differently from cassette drive. For example, during SEEK command, the tape unit signal Size error, if the Track is more than 1 (tape organisation is 2 tracks, 256 records).
I suppose that because the FD disk is organised as 2x77 tracks, 16 records per track, the SEEK command should also have two bytes (for compatibility), first byte is track number (0..153) and second byte is record number (0..15) right ?
My mass storage now emulates all operations with the tape (writing part of program is almost finished). Now, I need to extend the functionality to floppy disk emulation.
Thx for any informations
