Hi, Can anyone give me a clue on how to connect a monitor up to the 9100FT please? I have a B/W composite video monitor available to me (Tandy TRS-80 monitor), or of course a standard arcade monitor (10" MTC9000). Is it a simple case of wiring up the RGB and sync pins from the 9 pin d connector on the back to the arcade monitor or is there more to it than that? I don't know if the video card in this unit is B/W or Colour, or if indeed there is a difference. Do they all do both? And does anyone have any documentation specifically on the FT? Is there anything that says what the specific differences are beyond the HD floppy and the faster processor? There's 8 memory sockets for instance. Is that normal on all 9100's? Thanks, Martin. _______________________________________________ Techtoolslist mailing list Techtoolslist@flippers.com http://seven.pairlist.net/mailman/listinfo/techtoolslist
The video card can output B/W or color, this is set by the jumpers on the vidocard itself. Grab the service manual and look at the schem for the video card to work out what the jumpers should be (i haven't made a note of this unfortunately) but its obvious from the schems. I've seen docs that say the video is 'IBM CGA compatible'... it is true that it is low-res 15hz, it has seperate syncs, and they're inverted, so invert them then combine them in order to run it on an arcade monitor... I have tested working 30pin 1MB RAM simms if you want to beef yours up, one assumes you can give it 8mb ram with the right dip settings... 9100's only have 4 slots, and 4mb max ram.

Thanks Andy, Just to rig it up and see what's what I can use my 10" MTC9000 then and use the syncs as they are since it's got the sync polarity switch on it. Longer term that'll be a bit of a pain though so I guess I can invert them. I had flicked through the service manual but it's a bit vague in places and I wasn't sure if the video signals were TTL or anything. On the memory, it's already got 4MB of ram in it. Although I haven't bothered to look yet I guess it's 4 x 1MB simms. Every other of the 8 slots is free. I'll see how I get on for now but yes, it may be worth experimenting later to see if it can go up to 8MB :) Don't suppose you or anyone else have a spare set of manuals available for purchase? I do hate working off of computer screens! Cheers, Martin. On 18 Feb 2008, at 16:48, Andy Welburn wrote:

The development/editor apps were all designed with 4MB total in mind though, so its kind of a waste.
