Old Mac OS.... Help PLS!

by yaksaken＠hkstar.com

Hi there.... Recently, I just got an old Mac IIci, which has 40M HDD & 8M RAM. After all, I added the RAM to 32M, and also want to change the stupid 40M SCSI HDD to a larger one.... But the problem is, I just can't find a diskette version of Mac OS 7.5.x for it... What can I do...?? If anyone has the old Mac OS, would you all pls make a copy for me?? I will pay the shipping and diskette cost..... (Coz, I don't think if I can get a new copy from APPLE.. :( ) Yours, Ken Yaksa

Curious George Goes to Micro Center

by maxeskin＠hotmail.com

An anecodote: Today, two teachers from my school went to Micro Center to get some stuff fixed, and took me with them. This was the first time I have ever been in a tech service room. There was one tech, a woman in her 40's, multitasking. She was only able to fix our printer, which wouldn't formfeed due to a gob of glue. She "solved" the other two problems with updates from Apple's site. Anyway, while she was busy with us, a guy walked in with a Mac Plus mouse. She told him that the only thing that could be done is to order a new one, if they're still in stock. One the bright side, she didn't sell him a DB-9 Intellimouse but I think the only reason a mouse should be replace is if the case is smashed or it just sucks (Zenix?). How do you expect classics to survive in active use if they're thrown away without an attemp at fixing them? By the way, what's the difference between DB and DE connectors? ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com

Comments, anyone?? > Well, I'd give computer credit to Babage's machine, ca. 1896, IIRC. He is, > after all the one who coined the phrase "computer." Babbage died 1871 :) The Analytical Machine was never build and had never worked. Even the 1991 'replica' of the National Museum of Science and Technology in London was only build after his plans _and_ additions 'known' at this time. A neat (english) description of the Z1 and Z3 could be found at http://www.zib.de/prospekt/zuse/zusez1z3.html (Hard code documentation) or http://bang.lanl.gov/video/sunedu/computer/z1z4.html (soft :) The first programable general purpose computer is for shure the Z1. And the first electronic computer is the Z3 since the Z1 was just mechanical. Also both are the first binary floating point computers (Babage used decimal wheels). Servus H. P.S.: The first calculatin machine might be the one of Wilhelm Schickard from 1623. -- Ich denke, also bin ich, also gut HRK

AFAIK, none were sold, and they (it) cost a lot. :-) But they probably didn't track the cost accurately, since the machine was continually being extended - it (i.e. the physical hardware, not just the design) was used as a basis for the next couple of Manchester machines (including the mark 1, I think).

Is it straight, helical, worm or hypoid? Or an eliptical gear even? But yes, a gear is easy to rconstruct from its wreckage. Some cams and levers, though, have quite tight tolerance spikes and notches which it is quite difficult to get right from seeing the bent/broken ones. > Fixing one of these mechanical computers, however, is completely different > from the familiar digital ones.

In the former, problems manifest themselves in the outputs > giving out-of-spec or erroneous results (except with a catasprophic > failure!). Bearing in mind Tony's, Sam's and others' comments on intermittent faults and the like, yes, up to a point. Video is not the only exception, though - other things (e.g. disk drives) can suffer similarly. And finally, remember digital mechanical computers do exist - I have a Facit mechanical calculator with some quite sophisticated algorithms (optimised multiplication, non-restoring division) done digitally, entirely with mechanical parts. (The only electrical bits are a motor and a switch.) Philip.

That's a free added option that's built into many kinds of electronic equipment! It's called the TPD (tm). A.k.a., the "Technician Proximity Detector". There's a ton of them installed out there.

BTW, disgruntled French factory weavers who realized the threat of automated Jacquard looms to their skilled jobs were known to throw their wooden shoes, sabots, into the mechanical workings in order to express their displeasure at being replaced by a machine. Hence the the coining of a new word - sabotage.
