Oh! Well I've owned my M100 for years now and I had never seen the DVI. Are these rare? What advantages does this give over a stock M100 with a floppy drive? I gave a REX in mine, worth its weight in gold!

Thanks for the replies guys, I still ashamed I didn't know what DVI was.

Are these rare? Do many on the group have them?

DVI = Disk Video Interface. It expanded the 100 or 200 with a 180k 5.25" disk drive and an external monitor. Attaches to the system bus and has it's own DOS.

Perhaps I missed the memo, but I'm not familiar with DVI. Other than it being a firm video output.

What is DVI in relation to the M100?
