I didn't run the thing through the dry cycle either. Use strong, cool air to blow the water away. I always use compressed air from a supply for pneumatic tools.

Together with the energy cost for your dishwasher this tripples the value of the C64 board :) Gruss H. -- Ich denke, also bin ich, also gut HRK

dishwasher + mainboards

by allisonp＠world.std.com

ckaiser(a)oa.ptloma.edu hath spoke: < Good think you didn't run it through the dry cycle, or chips like the PL < might short out (very sensitive to heat). The dry cycle is ok if the temperature is under 180f, too hot and it can over heat parts. I prefer the oven at 160-180f as it's drier and a bit faster. A blast of compressed air is also good for getting water out from under parts to hasten drying. The PALS while temperature sensitive and no more so than any of the LSI on the board. < Are you sure the soap wouldn't have hurt the solder or board traces, < though? Your kidding? Soap will not hurt the solder or the boards. How do you think assembled boards are cleaned commercially? Allison

Anyway, in addition to being collectors items in their own right, they have the same basic mechanical and electrical components as the DECMates. Word I'm getting is they'll go for cheap to anyone looking to keep them alive or in need of parts, at or just over scrap value. Also up for grabs will be at least one major PDP-11 system. I'll keep the list posted with the latest news including when and how to order your own PC-Clone and DECMate repair kit. dmr David M. Razler david.razler(a)worldnet.att.net

Picture up (RE: Microsci HAVAC)

by CLASSICCMP＠trailing-edge.com

I agree - the door doesn't look anything at all like a Disk II. >BTW: I used to have a Disk II, and the heads were positioned by a stepper >motor, and didn't have any "spiral-grooved disc" anywhere in the entire >unit. I've had several dozen Disk II's, and they all had stepper motors with spiral grooved disks. Many, many drives were based around the SA390 and 400 mechanics, and some of them look quite dissimilar from the outside despite the fact that their internal mechanics are very similar. Kai - you mention on your web page that when you turn the machine on you go into a boot ROM monitor. What are the prompts like? Any copyright notices? Menus? Any "obvious" commands? Tim.

Items FS or trade

by rhblake＠bigfoot.com

Since I shut down the at home/on site business here and went to work as an ISS/CSS at a local corporation I need to do some cleaning out of excess here. I have many, many machines from 8088 through 80386DX that I can make a reasonable deal with someone on (not as cheap as an unknown condition thrift shop sale though) for mostly main units (you add the KB and monitor in may cases) but I have a few setups that are complete such as a 5150 PC that does have a 5151 monitor and original keyboard. PS/2's out the bung hole, Dells and AT&T's, etc. Many will have to be dug through when someone inquires about the condition and what it includes but 99% are in great condition other than minor wear and tear. I'm always looking for odds and ends for my machines here such as drives, cards, modems, etc as well as electronics test equipment for my bench. If you have something to trade rather than cash (which is my favorite, as is many other's) then let me know and we can go from there. Please email me direct so this isn't a problem with the list. I hate putting this on here but the people on this list seem to appreciate good sturdy hardware and see the actual value and use for it rather than seeing a pile of scrap with gold retrieval possibilities.

Marketing (was Re: Columbus analogy (Was: Corrections to trivia

by maxeskin＠hotmail.com

The thing is, people bought their earlier products when IBM won in its battle with NCR. When IBM began to make computers, it was already well estblished in the business world. Do people mean a product with good ergonomics or with easy repairs in mind as marketing? That plays a role, though it has nothing to do with the quality of the product or its innovativeness. >> I would be very flattered that you attribute: >> * 40 years of corporate stability to marketing >> * extensive manufacturing capability to marketing >> * cash reserves to sustain development to marketing >> * vast R+D resources to marketing >> * world-class documentation to marketing >> * world-wide customer support to marketing >> * a simply immense infrastructure ... to marketing! > >Do you think they would have any of the above if nobody ever bought any of >their products? > >Sellam Alternate e-mail: dastar(a)siconic.com >------------------------------------------------------------------------------- >Ever onward. > > Coming in 1999: Vintage Computer Festival 3.0 > See http://www.vintage.org/vcf for details! > [Last web site update: 09/21/98] > > ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com

Fairchild Channel F units

by dcoward＠pressstart.com

Doug Spence <ds_spenc(a)alcor.concordia.ca> said: >Speaking of which... how common are the Channel Fs? I picked up several >cartridges for one some time ago, but I've never seen the actual unit. >I've only seen ads for them in old magazines. > I see one about every two years. I have 3, 2 of which are in boxes. And I've managed to collect all of the regular cartridges, except for #26, in the boxes with instructions. #19 is the hardest to find. http://www.best.com/~dcoward/museum/mvfair.htm There was a second system (System II) that I believe was produced by the company that bought the rights to Channel F from Fairchild. The big differences in the two systems was that the original had a dark plexiglas cover over the controller storage compartment and the controllers were hard wired into the unit. It was the first home video game system to use programmed cartridges, but I think the cool thing about the Channel F was it 4 axis controller. ========================================= Doug Coward Press Start Inc.
