SedOric-3 and INIT command
Posted: Wed Aug 08, 2018 12:12 am
This is my recent Oric-toy configuration:
- Oric Atmos
- Original Microdisc controller
- Drive A: Gotek floppy emulator with OLED and buzzer mods (I will post more info in separated thread about it).
- Drive B: 3-inch double-sided drive, max 42 tracks.
Everything works perfect, but I found something strange with INIT command.
I boot from drive A and want to format the disk in drive B, so I type the command: INITB,17,42,D
The formatting starts fine, but the drive B is NOT always re-calibrated i.e. the magnetic head is NOT on track 00 and as result the command fails.
So, my questions are:
Is this behavior of INIT command already known or it's bug?
Is there a standard way to force drive re-calibration?
Or maybe I do something wrong?
Below is my temporary solution - redrive - small program, Atmos only,
which makes drive re-calibration using FDC1793 command restore.
The attached archive contains DSK, TAP and source! .
Any comments are highly appreciated !
