SCSI questions

by JRichardson＠softwright.co.uk

>> 1) Is the SCSI drive (a 170 MB Toshiba) toast? Can it be fixed? It *should* be OK; but it does depend on the drive. I've accidentally connected stuff up backwards once and no harm came of it. > >> 3) There's no separate SCSI setting under "drive type". Should I use "no >> drive", or set the parameters to something? I don't know about integrated controllers - depends on whether the controller has a BIOS to it or whether it's just dumb. Sounds like you've got a standard AT BIOS that supports IDE drives, in which case the SCSI controller's either completely dumb and you have to boot from an IDE drive, or (as with standard SCSI controllers) there's a seperate SCSI BIOS which needs some key-combination entered (such as CTRL-A on Adaptec cards) on boot up in order get into it and set up your SCSI devices. If you know who made the motherboard, you may be able to find info on the web somewhere... cheers Jules > >

Any collector will tell you that a lot depends on rareity. An item produced in the millions is less valuable than one produced in the thousands. Prototypes of popular machines will be very valuable. Machines that bombed in the market will be valuable. Accessories and documentation that disapears readilly will be valuable. Hm, how about masks of 386, 486, 586 chips.... from the manufacture process. Very rare and often beautiful. Most companies desroy them. Test runs of a product that didn't make it to market (anyone remember the Biin machine. I doubt there is a single example of that one left.) The Gold plated Cyrix Chips. Most will go to scrap for the gold content. Beauty has little value untill much later. Add art and design to your collectors criteria. Some of the speciallized gear to make systems work. Ethernet repeaters, thick cable, some of the first fiber optic gear, routersand other peripherals. Anything that helps popularize or develop new concepts and revolutionary equipment changes. Yes the iMac will be collectable because it is taking a lot of new people into the land of computerdom. It is a revolutionary device, the thought of unpacking it from the box, plugging it in and going to work is very attractive to new computer users. How many computers of today will survive when crashes become totally unacceptable. It will be 20 years though, before it gains value as a collectable. Any limited edition iMac that Apple may make will be collectable. This is going to be the first computer for millions of people. Follow important people in the field. Many of the computers Steven Jobs had a hand in are collectable. I bet there will be more. Paxton

Future Collectables - Mac, iMac & Atari comments

It was called the Macintosh. >> True, the Macintosh was a revolutionary concept and the 128K original is now a collectable. Many people bought Macs as their first computer. This generates popularity, time generates nostalgia. E-mail is pushing many computerphobic people into needing to use a computer. This is a new step in the revolution which is going to bring a great majority of people into the computer revolution. Apple & Jobs recognized the movement and, yes, used the trick again. This is generating huge sales for Apple and in 20 years down the road, nostalgia. Lets look at a simplistic history of the Mac collectables. The hottest of the predicessors is the Xerox Alto followed by the Xerox Stars the 8010 (limited production, very collectable) and 6085 (pretty, beginning to be a collectable). All of the Lisas are collectable as are any parts, documentation and software. The 128K original Mac is collectable as are parts, documentation, software and the original boxes. I suspect that early 512K Macs are growing in collectability. Right now Mac+s are a glut on the market. Early serial numbers, originals and limited editions will be valuable in the future. The production runs on the Mac + were huge. Untill the glut disappears prices will be depressed. Now is the time to buy parts machines. I doubt the Mac+ will ever be a great collectable, there are just too many of them. Many people will want one for nostalgia reasons only. Maybe in 50 years or so they will be valuable. I don't know the later Macs. Some I am sure are and will be collectables. The iMac will be a collectable because many will use it as their first computer. Most will move on to newer machines. Some of the originals wioll go ionto the closet when people upgrade. Most will go to the used market. When a new generation of power (64 bit machines) becomes availiable most imacs will go to scrap. This will be the bottom of the market. This will be the best time for the true collectors to buy parts, however most won't recognize it. As they become scarce they become collectable and prices rise. At this time most documentation and software is hard to find. Original boxes nonexistant. The machines that are buried in the closet start showing up on the collectors market. Top prices are obtained by having the origional boxes, documentation and software. Collectors pay a premium for this. This was exhibited in the record sale price of the recent Atari 1200XL on e-bay. This unit was the only totally complete system I have seen on ebay. Original boxes! If you look at the completed sales of Ataris most sales of 1200XLs are in the $30 to $100 range for complete systems without documentation, SW and boxes. Paxton

Ok you asked for it <grin> The Altair sales team was invited to give a demo of the then new 8800. They all showed up complete with a model 33 tty machine which was to read the paper tape for loading the Altair. The paper tape was loaded and the tty clanked along for about 4 to 5 minutes and finally stopped with the altair system loaded. They gave their dog and pony show and then asked for comments. From the back of the room my friend (the designer of the first digital group computer) said he would like to make a brief demo. He carried his equipment up front (under one arm ) and placed it on the table. The digital group system was loaded by means of an audio tape recorder. The loading time aprox 10 seconds. The computer then was able to run all of the basic routines written at that time. Well, the Altair guys were a bit unhappy. I know its shortcommings just like many of >> the other early machines.

Computer in Wyatt's room in "Weird Science"

by rcini＠email.msn.com

This afternoon, I watched the movie Weird Science for the thousandth time, and I have a question. Early in the movie, when Gary and Wyatt are first "building" Lisa, they are working at an all-black computer with two monitors (one is a green-screen and the other looks like a 19" color monitor). The system does not look familiar. Remembering the thread about the "War Games" computers, does anyone know: 1. Who made the computer on the desk? You can briefly see a logo on the front which looks like "TDK". 2. Which system(s) did they use to create the wire-frame graphics? The movie is (c) 1985 if that helps placing the technology. War Games is (c) 1983. Rich Cini/WUGNET - ClubWin!/CW7 - MCP Windows 95/Windows Networking - Collector of "classic" computers <========= reply separator ==========>

Early Desktop Calculator Directory on-line,

by aknight＠mindspring.com

Hello, I just completed one of the projects I've been working on for my calculator Web page and thought it would be of interest to some of you. I've published a directory of desktop calculators that were manufactured from 1964 through approximately 1975. There are nearly a thousand machines listed in the directory. Included in the directory is information such as manufacturer, model, display type, # of memories, and decimal setting. There is also a "notes" column where I list if a machine has other capabilities such as programmability or scientific functions. There were quite a few high-end programmable calculators made during this time, many of which were advertised as being more cost-effective than mini-computers of the timeframe. Examples would be the HPs, the Olivetti Programma series, Compucorp machines (also marketed by Monroe and Dietzgen), some Sharp machines, and a few others. The directory is linked from the "desktop calculators" section of my Web site. It was quite a lot of work to pull all this together, I hope some of you find it useful and enjoyable.

It has all the issues of the PPC Journal (including HP65 Notes, PPC Calculator Journal, and PPC Computer Journal). I haven't looked at all the issues yet but I'd guess that the PPC Computer Journal gives pretty good coverage to things like the HP75 and HP85 computers. For $20, it's a great deal. I think Jake said there's over 7000 pages of scanned material on this 2-CD ROM set. Regards, Alex Calculator History & Technology Archive Web Page http://aknight.home.mindspring.com/calc.htm

Good day, all... I picked up an Epson HX-20 this weekend (with a rather thick and complete technical reference (the HX-20 Answer store is now open...)) The odd thing is that it *doesn't* have a built in microcassette. It did however come with the a cassette interface cord ala ear/mic/aux for which the machine is jacked. All refs (including aforementioned tech ref) to this machine I've seen show the integrated microcassette... Any info? anybody? Mike: dogas(a)leading.net

Info on H-I Plotter

by rcini＠email.msn.com

Today, I picked-up a Houston Instruments DMP2 plotter. The plotter looks like a really old 8-1/2x11" X-Y plotter with manual pen selection and what I think is an RS232 interface (internally, it's hooked to an AY3-1014). Does anyone have any info on this beastie? Thanks. Rich Cini/WUGNET - ClubWin!/CW7 - MCP Windows 95/Windows Networking - Collector of "classic" computers <========= reply separator ==========>

HP Preservation Efforts

by rigdonj＠intellistar.net

Doug, Thanks for the info. I'd heard some rumors of some one cutting a CD ROM of HP docs but I didn't know who was doing it. Have you gotten the HP 110 stuff yet? I haven't. I E-mailed the guy and he said that he'd send the stuff to you but hasn't sent mine yet. OOPs! Forgget that. I just read your second message and I see you got the stuff. How does it look?

Short Intro

by hhacker＠gte.net

Kilobaud, when it first came out, provided the option to obtain a "Lifetime Subscription" which I recall cost $150.00US. Given that Kilobaud was so short lived, I do not think that those who purchased this subscription got their money's worth. Anybody recall things differently? William R.

"Softstrip" (Was: Kilobaud Magazine

< > As with all the others, it hung around for a year or so and then folde < > People just didn't like the concept I suppose, or maybe it just wasn' < > accurate enough (I don't know since I never actually used it). Neither, it was an attempt to distribute software. With floppies becomming more common and genrally dropping in price the floppy became the preferred mode. At the same time BBS systems were becomming common place enough to download software as well. In the larger view of technology it was a attempt to solve a problem that other solutions would displace. Other interum solutions included those thin records distributed by Interface Age that used the KC cassette interface standard. Allison

More or less there have been also 486SX with full working but disabled FPUs, since the 486SX was also used to deploy a lower price unit without touching the 'real' 486 price. > As for a Math CoPro for the 486, I'm not sure I ever saw a 487 chip, but I > always figured that they took the chips that didn't cut it as a normal > processor but had a good Math CoPro, and sold them as 487's. No, the 487 was just an 486DX with no modifications to the processor it self - just (AFAIR) one of the former unused pins now delivered a signal to disable the 486SX. So systems with 486SX and 487 just had two complete CPUs (And double power consumption :). > I've no idea if this is true, but it made sense to me, since why through > out a chip with a good processor, with you can just package it as a 486SX, > and sell it at reduced cost.

Gee - I had a 8087 in my first XT - I never used it beside some tests, but i HAD one - super power computer ! Yes, I wrote some programms to play with the ability to have two concurent processors running, but no real world app. And I still don't know for what a FPU is usefull - Anything can still be done in integer - you just have to think (sometimes a bit harder) about what you are about to do.

ePay revisited once more

>>The problem you're encountering isn't an error in math, it's an error in >>understanding. You're misunderstanding is common becayse Ebay words thier >>rules rather crappily. >>You are charged 5% of all sales up to $25 PLUS an additional 2.5% for $25 to $1000. >>So using the printer that sold for $41, you get charged 5% for the first >>$25 (1.25) then 2.5% for the additional $16 (.40) for a total of $1.65. >>I know, it's a weird system :) You may think that it is wierd for ePay, but it's not uncommon to United States citizens as a whole. That type of system, called a marginal rate scale, is used by the Internal Revenue Service (but called "tax brackets") for calculating your Income Tax. Yes, folks, ePay uses the same system as the US Government uses. The only difference is that the IRS marginal rate increases as the scale goes up; ePay's goes down.
