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

by maxeskin＠hotmail.com

But since most working implementations of an 8088 (the only one I have the databook for) require additional ICs, I'm wondering if it could truly be called a single-chip CPU. I mean, this thing needs chips for the clock line (8284, this says). It needs more chips for accessing RAM, and it needs RAM. Why do you say it's single chip? I think the only way to determine if it's a microprocessor is to look in the company's literature. If they call it an arithmetic logic unit, it's not a microprocessor. >failed to produce a working single-chip CPU before Intel. > >TI had a design, but it didn't prove to be manufacturable. > >Even if not everyone here agrees that being on a single chip is a necessary >condition for something to be called a microprocessor, to the best of my >knowledge no one disagrees with the claim that Intel as the first to make >a single-chip CPU. > >Eric > ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com

dishwasher + mainboards

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)

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.

Just gotta be sure you pull the board before the rinse cycle :-). Then it's usually best to rinse it with distilled water. -- -Jason (roblwill(a)usaor.net) ICQ#-1730318
