Apple Floppy Drives (was: More Apple Pimpers)

Especially if the batteries in the calculator are dead ;) (BTW, my 14-year old son has three slide rules and was quite interested in the giant one up on the wall in a hall at his high school.) -----Original Message----- From: One Without Reason [mailto:vance@ikickass.org] Sent: Thursday, November 08, 2001 2:41 PM To: Classic Computers Mailing List Subject: Re: Apple Floppy Drives (was: More Apple Pimpers) > > Good point!

I can do a lot of things faster on a slide rule than an electronic calculator. Peace... Sridhar

The most words I heared about the 8" drives are like: "Reformat > them at least once a year, or you will loose your data." The Eagles more so than the 8" drives. I've used a few of the 8" drives on larger Suns but didn't have great luck. Good performance though, especially on the Xylogics 7053 and 753 controllers. > I know.

Not to forget that incredible sound! :-) Oh yes! I used a few NEC D2352H drives. Those were sweet! -Dave -- Dave McGuire St. Petersburg, FL

> Adam was made in God's own image, not that of a monkey. My only dispute with Adam and Eve (and if anyone wants to have a theological debate with me, that is fine, but lets do it civilly and OFF LIST, as I can wage arguments for and against the existence of god)... My dispute is, according to the King James bible (I am specifying a version, as there are many, but the King James is the one that seems to have been adopted by the mass of Christianity), God made Adam. Then God made Eve. Then Adam and Eve had two sons, one killed the other and then was banished to a far away land. Now the obvious problem is, where did the rest of humanity come from... the obvious answer, Adam and Eve had additional children that just weren't documented. I don't have a problem with that. What I have a problem with is, Cain returns to Adam and Eve... with a wife and children. But if Adam, Eve, and Cain were the ONLY people on Earth when Cain was sent to a far away land... where did he find a wife to have children with? And of course, God can be "proved" and "disproved" (there is actually no one proof one way or the other that has stood up to all tests as far as I have found) with no interaction with the bible, which was written by man, and thus prone to man's interpretation and man's errors in omission, or embellishments, so the whole story of Adam and Eve has no ultimate bearing on the existence or lack there of of God, and in fact, can safely be disregarded as "folk lore" without damaging the underlying belief structure of God. And that is all I will say on this on list (sorry, but theology debates can get very heated very fast and aren't usually a good topic for open public debate... although they can be a very interesting philosophy topic when rationally discussed in a small open minded civil group.) -chris <http://www.mythtech.net>

I plan on following the sale to see what he does get. One of the things I noticed about the sale is that the seller is in Ketchikan Alaska. This is about one of the most expensive places in the US to ship out of. It could be prohibitive in cost to ship an entire Lisa. Most of the parts could be shipped priority mail however, at a fixed cost. >From reading the sellers feedback and reviewing his shipping charges I suspect his handling charges are a significant part of the additional charges. The more pieces he sells the better off he is. I also notice his regular business is concrete and scaffolding. His eBay sales are a sideline. Paxton Astoria, OR

New article on Vintage Computer Festival website

by vcf＠vintage.org

I just posted the paper I gave at an archaeology conference in Vienna, Austria, earlier this week. It's titled, "The Valley of Lost Data: Excavating Hard Drives and Floppy Disks" and was written with Christine Finn, author of _Artifacts: An Archaeologist's Year in Silicon Valley_ (http://www.artifactsthebook.com). You can find it here: http://www.vintage.org/cgi-bin/content.pl?id=004 Abstract: This paper explores some ideas concerning computers as repositories in the sense of archaeological sites containing data - objects, bodies and so on. The authors, who are both involved in computer history (one an archaeologist and writer on the subject, the other a leading collector and curator of vintage computers in the US) will consider the ways in which material in a computer may be accessed in the manner of evidence extracted >from sites in a more orthodox archaeological situation. The paper will look at the type of data stored, the hardware and software implicated, and the ways in which it can be retrieved. They will discuss issues concerning the ethical retrieval of such data and the time-frame involved in the transformation of material to a state of inaccessibility.

I have complete AT&T 6300+ computer with ATT Unix System 5/Release 2 (?) I believe. It has all the user manuals, and software disks. There are a bunch of them. I would trade or sell this system if you're interested. I'm in Seattle. E.

Apple Floppy Drives (was: More Apple Pimpers)

by ajp166＠bellatlantic.net

General comment, Most 8" systems were expected be and behaved reliably and have at least 250k of space. Most 5.25" systems could be reliable but, often weren't. I'll restrict comments to 5.25" for the later reason. Most of the complaints I've had with disk systems be they Apple or not were often in this order. 1- Drives (SA400 was pure garbage!!!) 2- horribly botched controllers (TRS-80 without mods) 3- software such as disk drivers that would hang if no media or errors 4- floppy drives/controlers that would "bite" the media on power up or down. meaning it would write trash due to no write locks. 5- not enough space The apple-II was plagued with #1 and somewhat with #3 depending on OS and definately #4. Space was a problem for many users(#5) Trash-80 was 1 through 5 example. NS* mostly #4 had to be watched if the drives were seperately powered and earlier units were SA400 (#1 problem). The SD controller while bullet proof was space poor at 90k per drive (#5). CCS used 8" disks and reliable controller. It was however prone to #4. Many S100 system that used 8" drives and the better 5.25 drives fell in this realm of reliability though most with 5.25 were pretty cramped until 360k(DD) or 720->780k(QD aka two sided DD) formats were common. Of the most reliable my AmproLB+, Kaypro 4/84 with Advent turborom,NS* (both SD and DD) and most of the post 1981 systems in the commercial systems space. My expectations of reliable were set by minicomputers long before micros I'd worked with where if the disk didn't work it was something I did wrong. Of all, my opinion is that floppies were ok but the first real improvement was the 3.5" drives(720k and 1.44m generation) with the power fail logic on board. They offered good storage, small size, lower power, good reliability and quieter than the whole lot. Allison
