Troubles with BlueSCSI-v2 and a Mac Plus

[rail2rail]

Cannot get the Mac to boot. Went through all the troubleshooting, different images etc. and no joy. I did the diode mod to the MLB and have the ini file on the SD. Also tried powering off USB. Updated the FW on the Pico with latest version, log file looks happy, to me anyway. Also, is the logged voltage supposed to be 3.2V or 5V?

Here is the log file:
log.txt

Here is the ini file:
[SCSI]
System=MacPlus
Debug=1

Tried the ini without the Debug option as well.

Any other ideas? Thanks!

2 things:

1. Disable debug - as mentioned on the compatibility page you can not run a MacPlus and Debug at the same time.
2. The image name suggests this image is for a HD20 (not SCSI) - it will not have the SCSI driver partition required to boot. Please try one of our premade images in the docs.

The voltage will warn you if out of spec - it should be around 3.3, 3.2 is fine.

Do you get the X regardless of the BlueSCSI being plugged in or not? Is there a floppy disk in the drive? Do you have a floppy drive connected? There can be a lot of oddities with floppy drive cables, bad drives, or not having a drive that could cause the X on boot. That image should boot fine on a Plus.

Yes, I do get the X with or w/o BlueSCSI. The FDD is connected and I can hear it seek and eject over and over. There is no disk in the FDD.

I guess I should try unplugging the FDD?

Thanks, Steve

I would start with unplugging the FDD and trying - though sometimes even no FDD can cause the X. Going a bit beyond BlueSCSI at this point - I'd suggest you ask your FDD question over at https://tinkerdifferent.com with a wider audience who might have seen this issue before.

I unplugged the FDD and it booted right up!
The FDD was dirty and nasty with old dried up grease. The disk transport was stuck in the loaded position with no floppy. After some compressed air and a few drops of gun oil, it is working great again.

Glad it was that easy, enjoy!
