It placed the moitor, a keyboard, joystick, four floppy drives, printer, and a clock on the screen. Then you could actually click on the keyboard's keys or move the joystick on the screen with the mouse. A really neat interface which, IMHO, did a half decent job at preserving the hardware's feel. It's a shame more emulators don't do such a good job at portraying the hardware. Tom Owad -- Sysop of Caesarville Online Client software at: <http://home.earthlink.net/~tomowad/>

Quantum Q540 as a RD52

by CLASSICCMP＠timaxp.trailing-edge.com

>Thank you from me too, Tim!!!! You're welcome! > I'm going to later this fall/winter try to >start-up my MicroPDP-11/73 and MicroVAX-II machines (along with an 11/34A, >11/24 and 11/23, maybe the VAX-11/730.) Of course, there are a couple of >RD's involved within the uPDP and uVAX here. I've been slow in putting RQDX3 details on sunsite's PDP-11 archive, I will admit, mainly because I despise RD-series MFM drives. Most of this is because I don't get called in until the RD drive is very sick and dying, and of course the users didn't make any backups for the past decade! You better believe that I charge a sizable fee for data recovery/system restoration in this case! -- Tim Shoppa Email: shoppa(a)trailing-edge.com Trailing Edge Technology Voice: 301-767-5917 7328 Bradley Blvd Fax: 301-767-5927 Bethesda, MD, USA 20817

>> mvII diag cust >DON'T ERASE THIS ONE ! Why not? The customer diagnostics are completely worthless. If one tries to use them to format a RD-series disk on a RQDX3, the best possible outcome is that an already formatted disk will remain formatted. A more likely outcome is that an already formatted disk will get zorched! Tim.

Monitor repair

by roblwill＠usaor.net

I have the same monitor. Don't have the same problem, though. It may be just the picture tube warming up, which would explain why the chill spray doesn't do anything. Although 10 minutes seems like an awfully long time for tube warm-up. Mine gets to full size, and warmed up in about 15 seconds. It's from 1992 (or93). I have noticed, however, that since I got it, the picture is slowly shrinking. When new, I could adjust both horizontal and vertical, when maxed out, would be past the edges of the screen. Now, when I max out the horiz. control, I can only get it to about 1/2 - 3/4" from each side of the screen. The vertical can still go off the screen. Other than that, there are no problems (no pincushion, distortion etc). The monitor is very low hours. It was used probably about 3-4 hours a week, if that, until about 4 months ago. Now it's used about 3-4 hours a day. The problem started, however, when being used 3-4 hrs. a week.
