RE: Re: [ql-users] Is there a Qdoctor in the house?
What I did on the I/O cards that passed through me was remove the metal locating strip, and file the cutouts which screwed onto the D plugs so that the card sat lower onto the board sockets. I loosened the nuts and found enough play in the metal strip to be able to slide it a couple of millimetres which was all it needed; however the remaining problem is the card doesn't sit close enough to the slots in the back panel to be able to screw it down without pulling on it to line it up with the screw hole. When I do that I can see the tension lifting the mainboard. That is probably because the stand-off at the far end of the mainboard isn't high enough. For the time being I've left the card unscrewed so it can find its own position. It is clamped in place by the overlapping head of the screw holding the blank plate covering the slot below. It's all back in the case now and was running lastnight for a couple of hours without problems. I'll have to make sure I'm very careful when I try connecting a printer to the parallel port!

It seems the mainboard is not perpendicular to the case back panel. It is close enough to enable the lug on the card's metal plate to locate precisely in its slot, but the gap increases towards the top edge. I have a cunning plan (actually plan A and plan B :) for dealing with this.

Re: [ql-users] Is there a Qdoctor in the house?
the carpet building up the voltage. I've been trying to think of a way to charge a battery off her, a kind of homemade cat-powered UPS... Hmmm. A neighbour of mine, here in Houston, TX, has built his own unique (for a home-made dwelling system) power system. Three 4' x 8' solar powered steam generators (tanks with water and black metal panels in them to absorb solar energy and heat the water they lay in) with plumbing to a pump connected to a generator, which feeds through diodes into a power controller and storage. He does need to use a few kwh of electricity in winter (in TX that's two months) and generates surplus power in summer, even after running the air conditioning of the house. OK, speak to Bill Cable over there on this subject...I think he's even used QLs in his eco-friendly setup. -- Dilwyn Jones [EMAIL PROTECTED] http://www.soft.net.uk/dj/index.html
RE: Re: [ql-users] Is there a Qdoctor in the house?
Last night I removed the Q40 completely from its case and set it all up on the table. It ran all evening (about 3.5 hours) with not a flicker of interference on the monitor. Not even when I picked up the mainboard, or prodded (gently) the video RAM chips. This suggests that when the mainboard is mounted in the case, with the I/O card screwed onto the back panel, the geometry of the case is putting the board under sufficient strain to move one or more chip pins in their sockets enough to break connection. There were no metal objects trapped between the mainboard solder side and case. Looks like a new box might be the solution. Ian.

[ql-users] Is there a Qdoctor in the house?
It was not a good weekend for my Q40. The problem is with the video. The machine boots and appears to be working because you can still see the picture on the monitor, but superimposed on it are shimmering horizontal lines that wander up and down the screen. Sometimes, if I switch off, wait a minute or two, then switch back on the picture will be stable but this is shortlived - the 'interference' soon comes back again. I've done as many basic checks as I can (I'm suspecting the problem is caused by dirty/damaged contacts somewhere) - the monitor works OK on a PC, the header plug connecting to the video pins on the mainboard is not loose (though not particularly tight either) and none of the pins are bent. I checked the seating of the I/O card, the contacts on the card are clean. Looking into the slots, all the contacts appear correctly aligned. I suppose there is the possibility of tiny breaks in any of the tracks on the board, but the only stress the board has had was when the I/O card was originally plugged in, and the machine has been working fine for a long time. I'm lost as to what to try next, and lost without my Q40. I started playing with FreeBSD and even did some housework - so that shows how lost I am! regards, Ian.

The sockets are staggered, and the pins are bent close to the edge of the chip and appear to have been stretched about as far as they'll go to reach the sockets.

RE: Re: [ql-users] Is there a Qdoctor in the house?
That sounds pretty horrible to me :o( I repeat This is _exactly_ how the chips are designed. They have the same pin layout as the GC/SGC memory chips, but are longer. Not horrible in the slightest (8-)# It's a chip package I've never encountered before; I accept the pin layout is as designed. I just got the impression they had been re-shaped to fit the sockets because the socket diameter is so large that they could not have been positioned any closer together (they look like individual single-pin sockets, but now I know it is a standard layout, they are probably all joined together in that shape). No, they are not horrible, they are exquisite (perhaps they are even available in a range of pretty colours) ;O) :) Phew, I'm glad the Q40 is at home - it would probably refuse to ever work again if it knew we were using words like 'horrible' in reference to it! I'll take out all the video RAM chips and reseat them. Quick question on a related matter while I'm here: How can I make an ATX PSU supply power to the Q40 with its normal mainboard connector disconnected, i.e. not receiving its wakeup signal?

Ciao A contact cleaning pen might solve the problem a lot faster (There are some that have a tip small enough to fit into a RAM socket) I was thinking of the simm, which has non-gold connectors. A rubber is OK for that. I hadn't realised until Q40 that simms used two connectors for each signal - sort of accepting the connections were dodgy. -- QBBS (QL fido BBS 2:252/67) +44(0)1442-828255 tony@surname,demon.co.uk http://www.firshman.demon.co.uk Voice: +44(0)1442-828254 Fax: +44(0)1442-828255 TF Services, 29 Longfield Road, TRING, Herts, HP23 4DG
