Warren, Let me make a correction. It is my Magnavox 8cm515 that doesn't scan all the way. Top lines are chopped off. As for the NEC 2a I was wrong in thinking it work. It did not sync up. My main trouble is I have 2 computers and only one monitor. Although the cm515 can be connected both to the MM/1 and CoCo(using compisite connections) and switch between them at the touch of a switch.

If you want one get my 'orderhard.txt' file from my MM/1 Official download section. These are reported to be very fine for the MM/1 according to James Jones of Microware.

Date : 94/12/10 13:19:50 Previous Reply is Message 1398 I'm not sure what 15" monitors that will deal with the 15.something KHz scan rate exist. I've recently purchased a refurbished Sony monitor through David Graham, but, sharp as the image is (.26 mm dot pitch, if I remember rightly), it's no bigger than the CM-8's. You might wind up looking in Amiga magazines, since they, like the MM/1, put out the same scan rate as a TV. BTW...a while back a place was getting rid of old hardware, and I picked up an old Intecolor device--I've been told by some it's a graphics terminal, though from looking at the key labels I woulda sworn it was a computer. It consists of a keyboard and a BIG, HEAVY monitor. Does anyone know if the company is still around, or of a manual for the darn thing? --- RiBBS v2.10 * Origin: Ocean Beach BBS 619-224-4878 MM1 TECH moderator (1:202/745) Public Message (Rec) Message # 1515 *MM1 TECH Echo* To : Warren Hrach From : James Jones Subject : Re: Monitor for MM/1? Date : 94/12/10 13:26:00 Previous Reply is Message 1404 There for a while, I was hoping to get a Mitsubishi Diamondscan monitor that was listed for pretty cheap in a California Digital flyer. Alas, when I called, I was told they were out of stock. The other day, I got a call back, saying they had some, but instead of the $140 or so the flyer mentioned, they were talking $250. Since I'd already committed to getting a monitor via David, I said I appreciated the call, but I'd already gone ahead--you might want to check them out, though. --- RiBBS v2.10 * Origin: Ocean Beach BBS 619-224-4878 MM1 TECH moderator (1:202/745) Public Message Message # 1516 *MM1 TECH Echo* To : All From : James Jones Subject : keyboard Date : 94/12/10 13:29:41 Well...at Babbage's I saw this Addison Technology ergonomic keyboard that claimed to autoswitch for XT/AT/PS2. I got one this morning. It feels VERY nice, and the split angled key setup certainly forces good typing style on one...but despite the claimed functioning for XTs, my MM/1 doesn't talk to it. Has anyone else tried this particular keyboard? (Maybe I just got a bad one, or maybe it needs that capacitor hack that some folks have said they had to use to get certain keyboards to work.) More generally, is there any chance that it will be possible someday to hack the MM/1 to use an AT-style keyboard? Those XT keyboards are getting a little harder to find. --- RiBBS v2.10 * Origin: Ocean Beach BBS 619-224-4878 MM1 TECH moderator (1:202/745) Public Message (Rec) Message # 1548 *MM1 TECH Echo* To : Warren Hrach From : Stephen Seneker Subject : Re: Monitor for MM/1? Date : 94/12/10 00:22:00 Next Reply is Message 1559 What are the specs required for a monitor to be compatible with the MM/1 video? Presently I have in mind a Magnavox CM2015. This is a 15" monitor with Max Res 1280 X 1024 @ 60Hz refresh with a horizontal scan of 50KHz. However I would consider a used monitor if the price is within my means. I'd like a LARGE one preferably something 15" or better.

Date : 94/12/11 08:35:10 Previous Reply is Message 1548 Be careful! You need to know the *minimum* scan rate as well as the maximum. These days monitor makers seem to think the whole world uses PClone VGA cards, and not many you'll find bother to deal with scan rates below 30 KHz. In *Computer Shopper* these days, the only monitor I've seen that comes right out and says it will do 15.75 KHz is a 27" monitor that Midwest Micro advertises...for $2900. You might want to check USENET. --- RiBBS v2.10 * Origin: Ocean Beach BBS 619-224-4878 MM1 TECH moderator (1:202/745) Public Message Message # 1559 *MM1 TECH Echo* To : Stephen Seneker From : Warren Hrach Subject : Re: Monitor for MM/1?

It helps when one can see... %-) Stephen, The CM2015 will not work since it has no horizontal scan of 15.75Khz. You might look around for NEC 5D , those were I think 17" size otherwise same as the 3D. The 3D is 14" same as the Sony's now available. Same as the Magnovox 8cm515 and 1cm???.

The Sony 1302 WILL work VERY VERY WELL with a CoCo 3, and it therefore should work just fine with an MM/1, which produces the exact same sort of analog RGB video as the CoCo 3 in all important respects. At least, given your assertion that it is RGB analog, and that it supports H sync frequencies at 15.75 KHz (the last is critical... most modern "multisync" monitors don't bother with supporting such low frequencies!), it should work fine. If I am not mistaken, the Sony 1302 uses a 9 pin DIN connector for its RGB video. The pin out is DIFFERENT from that used by NEC multisync monitors with 9 pin connectors. This is worth noting by others, actually, so I'll elaborate here: The "Sony Standard" (also used by some Magnavox multisync monitors from the same or just earlier period) for pin out for analog RGB is as follows: 1,2 Ground 3,4,5 Red, Green, and Blue analog luminance (0 to 1 V p-p, more or less) 6,7 NOT USED 8,9 Horizontal and Vertical sync, respectively. Note that I recommend, when you make up your video cable, that you use 11 conductor ribbon cable, and designate every OTHER wire in the ribbon cable (including the two outside wires) as GROUND, sandwiching the 5 active signals (R,G,B,H, and V) between ground wires. This will give you very good transmission properties. The "Nec Standard" (also used by Tatung and many other "multisync" monitors from the period of the original "NEC Multisync" and "NEC Multisync Plus" and "NEC Multisync 2" monitors) is as follows: 1,2,3 Red, Green, and Blue analog luminance, respectively 0-1 V p-p 4,5 Horizontal and Vertical Sync, respetively 6,7,8,9 all GROUND Note that I kinda like the NEC standard better, because if you use the NEC standard and just CRIMP a DB9 connector to a 9 wire ribbon cable, you get every other line as ground, which is highly desireable for transmission of video over ribbon cable. So, Warren... if you just solder up a cable wired from whatever is the MM/1's pin out for its RGB analog 15.75 KHz video connector to the Sony connector, using the pin out I provided for that, you should get a VERY nice, sharp impage on that Sony 1302. It's really a VERY fine monitor. If you ever want to sell it, let me know! ---marty ------------------------ xpost end --------------------------------- If anyone wants one of these monitors leave me your Name, Address or call my BBS and download from MM/1 Official download section the file 'orderhard.txt' or freq it from 1:202/745.
