Since a few days, my EXORciser Development System is finally able to boot from floppy
diskettes.
Previous attempts have shown that the Motorola EXORciser M68SFDC1 floppy disk board used
has a special modified ROM version. This was probably written for an 8-inch drive, in
which the Write protect and Direction signal were inverted.
For the sake of simplicity, I have used free inverter on the board to invert the signals
accordingly.
After adjusting the PLL frequency, reads and writes from the card are now error-free. And
all without FDC, only clever programming by Motorola software engineers in the early 76?
Originally, the EXORdisk system was a dual drive with two 8 "units. This I have
replaced with a double drive of two 5.25 inch units. An Epson and a TEAC, which can be
jumpered to 360 rpm. Luckily, 2HD floppy disks are easy to R&W.
I also got a GOTEK floppy emulator running, which I can boot from. Thanks to Roland
Huisman, Bitsaver has some interesting floppy disks that convert to HFE format work
perfectly. This format makes the Gotek drive most reliable.
Now to my question. The vintage computer forum at
http://www.vcfed.org/forum/archive/index.php/t-44638.html mentioned some interesting
manuals. Archive.org has some manuals, Bitsaver does not have manuals about the M6800
development system.
If someone already owns scanned manuals to the following list
M6800 Basic Interpreter Reference Manual
M6800 Macro Assembler reference Manual
M68SFDU Exordisk 11/111 Disk `Drive Unit Maintenance Manual
M6800 Exorciser 11 User's Guide
M6800 Exorciser User's Guide
MEX68PP1 PROM Programmer Module Supplement M6800 Exorciser User's Guide
I would welcome any feedback or questions

Apologies if you already know about these, but Bitsavers did fairly
recently split some of the stuff from /pdf to /components.

Hi Kyle, thanks and good to know. I will include the Components folder in future
searches.
The M6800 Exorciser User's Guide is included, so there are five documents left.

6800 manuals?
I think I have all the wanted manuals physical + a lot more on the boards..
Also a lot of the boards + an Exorciser 1 setup with CRT interface
Got a couple of ADDS Viewpoint terminals if somebody should be interested
It's a last call situation as I am creatin space for newer things
Introduced the 6800 system on the danish market as MOTA distributor from
1975
Best regards David Christiansen

Hi David,
do you have Micromodule Manuals for the 6800 and 6809 single boards?
Cheers Thomas

You should also ask on the vcf forum. There are a number of 6800 people there.
