Fw: essay on bus structure

by jwest＠classiccmp.org

I was contacted by a student who is writing an essay on computer bus structure, comparing intel PCI bus to PDP-11 unibus. I'm certainly not qualified to give detailed information on this... so I'm passing it on here. If anyone cares to take a stab at this, you can contact her at: cqfranks at yahoo.com Caroline Jay West

Better indexing on bitsavers

by aek＠bitsavers.org

>> Doesn't this sort of imply that PDF is the wrong choice of format for >> jobs like these? PDF is terrible way to package the documents. >It's just better than any other practical method ;-) >So many talk about ASCII being the only "right way", as Al can attest to >time and accuracy makes image oriented PDF's the way to go. I'm pragmatic. I have hundreds of thousands (probably millions now..) of pages of paper. I wanted easy access to all of it. Eric also had a lot of stuff that I didn't have. The machines I use are Macs and Linux boxes. There are PDF viewers for both of those platforms that had page indexing. The level of PDF used is the minimum to support wrapping collections of scans together with very simple metadata (the page number). That's all of PDF that I use. The overhead is minimal, it can be read across most computers currently in use, and if it's working with the right sort of browsers will only transfer the page being viewed instead of the whole document. If something different comes around, the PDF spec is public, and by using such a small subset it should be simple to translate. I've never found much use for the fancier scripting stuff in tumble. It takes long enough to just do the minimal post-processing of the scans that I do now to think about writing a script for each document to do any sort of fancier indexing.

Free 8088 Zenith laptop

by classiccmp＠vintage-computer.com

Absolutely free (you pay the shipping): I have a Zenith Data Systems ZWL-184-97. It looks a lot like a SuperSport but it isn't. . . see http://www.obsoletecomputermuseum.org/zenith_l/ for a look at one in much better shape then this. Mine is yellowed and has a crack on the front left but it does work! It has an internal 3.5" floppy as well as a 20 MB HD. Given enough time (it's SLOW) it will boot to the HD which has WordPerfect and DOS 5.0 installed. The machine comes with a battery pack (dead) and a power brick as well as a spare 3.5" drive. All yours for absolutely nothing if you come pick it up in San Jose or for the cost of shipping if you want it anywhere else. It's gone by the end of the weekend, one way or the other. . . -- Erik Klein www.vintage-computer.com www.vintage-computer.com/vcforum The Vintage Computer Forum

Wanted: Rubber drive wheel for HP 9144 tape drive

by infomagic＠mail.localisp.com

Look up a company called "Star-Glo", at 2 Carlton Ave., E. Rutherford, NJ. I pass their building often, but I don't have a phone # or email. I'd think a web search would locate them. They fabricate dozens of compounds, and rubber seals and gaskets for everything from glass jars to submarine hatches. They also fabricate such parts as the rods in printers that have the molded-on rubber (or whatever) rollers. Good luck! -John ________________________________________________________________ Sent via the WebMail system at mail.localisp.com

Classic DEC picture from "American Used Computer

by aek＠bitsavers.org

"photo is scanned in from the October 1982 issue of National Geographic magazine" Unfortunately, the classiccmp links no longer match what Google thinks they should be. (Jay???) Here is what is in Google's cache: From: David Forbes <> To: Tom Jennings <tomj at wps.com> Subject: Re: Would you buy a used PDP-8 from this man? Date: 14 Jan 2004 13:37:17 -0700 Tom, This photo is scanned in from the October 1982 issue of National Geographic magazine, which I just found at the thrift store. It has an article about The Chip, and another about Silicon Valley. Humorous reading. The guy with the bowtie is Sonny Monosson of American Used Computer in Boston MA. I remember you saying that you used to go there now and then in your youth. I remember getting their ads in the late seventies, when I was using PDP-11s in high school and college. I would drool over the possibility of getting an obsolete 11 for home use, but the shipping was so expensive back then. I imagine the power bill would be something to behold also. All I remember about the Heathkit LSI-11 I used at Optical Sciences is that it was slower, instruction for instruction, than the Z-80 I also used.
