Re: [M100] Request for info on RS DV Interface
And, though it helps the OP not at all, I hope it's not too forward to note that I have two of these units, and need only 1, so I am looking to sell my second unit (works, with disks, with homemade T100 cable, 1 drive, missing drive bay door, good shape) Jim
Re: [M100] Request for info on RS DV Interface
Small nitpick: it has a ch3/4 RF TV output as well as the composite out. And of course the cable for the M100 is different from the 102/200. I believe there are sources on here for both the cable and the disk.

[M100] ROM disassembly
I'm using the m100 and especially the nec roms as a cross reference for my MSX disassembly (and vice versa). They are so close and in many cases it is of great help in identifying the constant values and the dynamic data, vectors, etc. In this way I'm now able to modify both the MSX and, still with some limit, the m100 ROMs. In the latter case I could rip off the terminal and modem programs (also from the directory) and use the gained space to improve the BASIC. I'd like to waste some more time and extract a generic portable BASIC from those sources, e.g. to see it run on, say, a zx spectrum, but moving it all in a 16k rom is probably VERY challenging. The similarities with the MSX are interesting, the nec has almost the same tokenization mechanism, but a different (older) floating point implementation, all the other models have the same FP engine (double precision, BCD encoding) but a different (older) way to deal with tokens. I suppose it was done to fit the code in the available space in ROM. Being able to assemble the program permits to quickly generate a MAP file. I think I found most of the used addresses and associated them to the declared asm labels.

Always wanted to have a DVI, just never seem to come up on eBay over here.

[M100] Request for info on RS DV Interface
I just acquired a Radio Shack disk video interface; I haven't plugged it in yet and it came with no documentation. It does have a port on the bottom - looks like a ribbon cable - and a couple of RCA jacks on the back, so there is a way in and a way out, but I don' know what it was designed to interface with. Maybe the M100? I think however that some of the community have these in their collection. I'd appreciate any guidance you can give me. Specs? Manual? Thanks for your replies. -CH-
