Jim the header you used to connect to the underside of the M100 is pretty darn sturdy, I'm not sure why it was acting up. Best guess it a loose wire some where or something like that, I'll check it out with my meter when I get started on this. Still I'm going to re-purpose it and try make a new, extended super DVI cable, which will hopefully allow me to use the DVI the way I want to.
For those who might like to know, thus far using the US DVI here in the UK has been a breeze. I'm using a step down brick for now, with a new PSU on the way. See link to new dual output PSU https://www.aliexpress.com/item/32981279958.html?spm=a2g0s.9042311.0.0.72964c4deypKfb Hopefully when this arrives, it will be (fingers firmly crossed) an easy job of swapping out the old US power supply with the new one and thus eliminating the need for the step down brick. I'm displaying the DVI through RF or UHF if you prefer and the picture while a little fuzzy is perfectly acceptable given the age. I've not actually look in to the DVI's other video output option, which I think was intended for Tandy branded monitors. I'm slowly figuring out a method for using the unit for writing, while being able to get the created document on to my NADSbox. I use the M100 for creative writing and also doing articles for my blog, so one way or the other the document needs to end up on SD card. Random question does the DVI save data to floppy disk in the same format as the TPDD?
