Sick Sorcerer. Diagnosis, Doctor?

I'm hoping for some insight from the clever people on this list. I am attempting to bring back up an Exidy Sorcerer disk system. I have a hundred or so disks for this system, and have just realised that I probably have everything I actually need for the disk system, too. Cleaning out the garage, found a twin-floppy drive which I thought had been gutted. But on internal inspection, it appears to only have had the cable removed. First question: there are two drives, and each has a set of jumper pins. The pins are labeled.. DS 0 1 2 3 MX MS H M H C The top drive, on which the red LED lights when I power the drive, has jumpers across DS1 and HC. I am guessing that this drive is the second drive, and that the two jumpers that fell out of the casing belong on the second drive. That should be, I'm guessing, DS0 and mmmh... HM? Can anybody enlighten me on this? Second question: Powering the Sorcerer (I thought I didn't have a monitor, but the VIDEO IN on my VCR works nicely - it shows up well on my TV) exibits some strange behaviour. What's trying to come up on screen is "EXIDY STANDARD MONITOR" and a few lines after that. But it simply stops after the second or third character. Repeated efforts see it stop in different places - sometimes you see the whole lot, and it's actually usable for a few minutes - sometimes you only see a character or two. Out of 100 resets, I'd say that it actually works on one (ie: 1%) and then only for a short while. But the strange thing is that, very rarely, it misses a character. So, something like "EXID STAN". Furthermore, it's quite obvious to me that the text is being put on the screen in a serial manner (slow enough to see). And finally, occasionally some of the text changes case (ie: eRROR - COMMAND NOT FOUND). At first I suspected the RAM, but have carefully reseated all chips that are socketed, with no effect. I found a homebrew cartridge for this machine, and when its plugged in, the wordprocessor it contains appears to work fine - everytime - with no apparent problems. Sure, I don't know the commands, but it does let me type, doesn't crash, and doesn't have any visible screen glitches as described above. For this reason I lean towards giving the machine's RAM a clean bill of health. So, the question is, what's wrong with the monitor? Third question: Assuming I actually get the machine powering up correctly, and that the drive I have isn't missing some vital component - it will be time to insert a disk. Can anybody tell me how to actually use a drive with the Sorcerer system? I'm afraid it's going to be some arcane "GO C800" or something like that, from the monitor. I think I might need someone with documentation! Any help appreciated.
