Hello just an update of the test I have been done:
Test setup:
- Dealer disk from from the repo from Mark : https://github.com/mark-usher/Pi1MHzFS/ ... eaved).adl
- Pi Zero 2W
- Acorn Master 128
- 1 Mhz level shifter from Mark
Test results firmware provided by dp11 ( downloaded 23 December 2025):
SCSI image source Theo O https://www.theoddys.com/acorn/replica_ ... _scsi.html
Format drive -> Select drive from Dealer disk
- Select drive : Gives Error &66 in reading drive shape ( Activity timeout)
Test results firmware provided by Mark ( also downloaded 23 December 2025):
SCSI image source Thee O https://www.theoddys.com/acorn/replica_ ... _scsi.html
Format drive : Full format of drive possible despite warning from software. Directory visible in ADFS
Initialise disc:
Possible to het disc information but when option 'W' is chosen an error is visible : 'No such FN/PROC (error &1D) at line 1400"
No need to add Overclock settings in the confix.txt. So here the optimalisation from Dominque works perfectly.
With Image:
https://github.com/mark-usher/Pi1MHzFS/ ... dDrive.zip
Possible to select drive no more warnings from the software one can not format the drive.
With the option Format drive:
Error &66 in mode select ( Activity timeout)
With additions in config.txtSame error :
Error &66 in mode select ( Activity timeout)
With SCSI images from Theo but ext from Mark
Same error :
Error &66 in mode select ( Activity timeout)
It looks that the scsi0.ext gives some issues.
