Mac Plus - BlueSCSI - Disk Jockey and Error 0F000A

I've followed the directions at BlueSCSI V2 and tried other instructions on the interwebs; getting nowhere with running BlueSCSI on my Mac Plus.
It's stock, an early version, 4MB RAM (so I guess it's NOT stock.)
I've formatted my SD card using the SD formatter app, overwrite and exFAT set. I've added "drives" using Disk Jockey, adding OS 6.0.8 and allowing Disk Jockey to do its magic, prepping the drive for SCSI use. BlueSCSI.ini for Mac Plus in SD root.
Mac beeps, looks around while then posts a sad mac with error 0F000A showing below the icon. I've looked for a description of the error code, finding nothing specific.
Any ideas? I've tried the suggestions on the BlueSCSI troubleshooting page. No change.
I've reformatted the SD card multiple times. I've switched SD cards too.
I'm guessing there's something, probably quite obvious, that I'm either not doing or doing wrongly.
Any help is appreciated.

Oops. My mistake/lapse/failure to attend:
(I notice that the third block includes "-- Enable SSCI2 is off"
I am not cognizant of turning on or off SCSI "drives" Where might that be so I can read up on it?

SCSI-2 referencing is the SCSI standard version 2, eg SCSI-1, SCSI-3, etc (not SCSI ID's). You can read about any of the ini settings here in the docs but you should not set any unless directed. System=MacPlus is what disabled SCSI-2.

First lets start by only having one known working drive to rule out any issues with images or the like. You can grab the 6.0.8 image from here and only have that one active. Troubleshooting is all about removing complexity till we find out the issue.

Well that did the trick. Blue loaded the OS. My mouse wasn't connected, so I didn't shut down properly. I'm guessing that's why no log file showed up.

Do I add the files/extras I want/need one by one, booting between each .hda file and/or directory?


BlueSCSI.ini =
[SCSI]
System=MacPlus

Log is created a few ms after powering on the BlueSCSI and has nothing to do with the host, it is quite odd, and I might suspect something odd with the SD card is going on.

There is a page dedicated page of options for transferring files to your vintage mac from a modern computer. BlueSCSI toolbox is a great little utility to do just that for files, or you can use CiderPress2, or an emulator to get files to your image file. Whatever is convenient for you.

Back to your original issue - It is most likely the images you were using had different SCSI driver partitions on them and conflicted with each other, not allowing the Plus to boot. Unfortunately early Macs can run into these issues when mixing different versions/vendors of SCSI drivers. Dragging the image on Disk Jockey can replace the driver for you if it's a known bad one, and show you which one it is in use.

MY SD card is a Samsung, 64GB. I read where you do NOT recommend Sandisk AKA Sundisk.

I have another Samsung 64GB. I'll give it a try.

You said "It is most likely the images you were using had different SCSI driver partitions on them" Is that sort-able via a more detailed ini file?

I was careful with naming each file, HDA, Toast, iso et al to make sure each was unique. Is that sufficient or is more precision required?

Thanks for your prompt assistance. I'm not proficient in coding etc. Ignorant, actually. I read the ini page you referred to and grasped 25 to 33.33 per cent of the content. I'm slow, but it takes me awhile. I know I'll get his sorted and have some fun while I do.

Thanks again for your help, Eric!

No, BlueSCSI is really just a block device, it knows (almost) nothing of the contents of the file - we do some very light inspections of the file to see if it looks like an HFS image when it's on a Mac, but that'ts it.

I was careful with naming each file, HDA, Toast, iso et al to make sure each was unique. Is that sufficient or is more precision required?
Just follow the Usage details on the wiki - i dont know what you mean about precision - if you name it something not known it wont know what to do with it :)

I read the ini page you referred to and grasped 25 to 33.33 per cent of the content.
Then you read the top part that said "Most users will NOT need to create this file, and should not unless you have a reason to." ;) - You and 99.9% of users will not need any of these settings.

I know I'll get his sorted and have some fun while I do.
Thats why we're here, to have fun and learn a thing or two :)

Glad you're getting it up and running - Mac Plus was our first family computer and I spent a lot of time on it (and still have it)
