I have a symptom almost like that with some copies of a system disk where the copy is bad. I think it was when I used a 100 and thus the 100 version of the backup program to make copies of the 100/200 version of the system disk. Those copies do not boot all the way on a 200. They do get past the first step, but then when I press reset on the 200, it looks like it loads, but the 200 is locked up at that point.
I have other copies of the same source disk which I made using a 200, and those disks boot properly on both a 200 and a 100. I have yet other copies of the 100-only system disk, made with a 100, and those boot properly on a 100. But copying the 100/200 disk with a 100 seems to have made a copy that doesn't work on a 200. I haven't done the necesary methodical testing to really prove that was the problem vs say a drive that's slightly out of alignment and writing a disk that another drive can't read reliably or any number of other possibilities. I just meant to say I have some disks that produce a symptom almost like what you have. On Jan 26, 2018 10:04 PM, "Randall Kindig" <[email protected]> wrote: Yes, of course, you’re correct. I’m not getting to that point anyway. I appreciate any help you can provide, Brian. I’m following the steps in every manual I’ve found. If I’m missing a step it’s certainly not obvious in the steps as I understand them. I assumed that if that if the DVI booted to the Microsoft screen the drive and disk were good. The issue is here that when the M100 is restarted nothing happens on the DVI. No reaction at all. The drive does not light up and does not attempt to read the disk to load BASIC.

SCREEN 1,1 I'll record a video tonight of the boot process just to remove all question marks if you're doing everything right. The steps are spelled out exactly in the user manual though. Jump to page 11 http://www.classiccmp.org/cini/pdf/Tandy/Disk%20Video% 20Interface%20Manual.pdf I'll show the symptoms if the disk drive is bad too, where the dvi rom boots itself ok so you get the first few messages on the monitor, and the drive does run on que, but fails to actually read the disk. -- bkw
