Jaguar Blaster (was Re: Ancient 8086/80286 unixes?)

The only mention I've ever seen anywhere of a Jaguar Blaster card is here: http://justclaws.atari.org/altatari/dxnews.htm Read some of the other items, and you'll soon get the idea that the stories aren't exactly true. Actually, there was a Jaguar-on-a-PCI-card project called JagPC that was at least announced by Sigma Designs. I don't think a prototype ever existed, but I could be wrong. Jaguars were pretty good 2D pixel-pushers, and would have made a respectable graphics card for the time period. -Jeff jba at sdf.lonestar.org SDF Public Access UNIX System - http://sdf.lonestar.org

Spanish speaker for spanish radio interview?

by sellam＠vintagetech.com

Does anyone speak fluent Spanish? If so, there's a spanish-language radio station in Florida that wants to do a 7 minute interview about vintage computers today at 2:15PM (Eastern). Contact me ASAP if you'd like to do this and you speak Spanish. -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org [ Old computing resources for business || Buy/Sell/Trade Vintage Computers ] [ and academia at www.VintageTech.com || at http://marketplace.vintage.org ]

PS/2 webserver

by lproven＠gmail.com

Merely curious. Does anyone know of any IBM PS/2 machines - the proper Microchannel ones - hosting websites today? I know of a number of very old Macs doing so, including a Mac Plus with a website on floppy, machines running System 6 and AU/X. I've even visited a website hosted on a Commodore 64, I seem to recall. But never a PS/2 one. -- Liam Proven ? Profile: http://www.linkedin.com/in/liamproven Email: lproven at cix.co.uk ?

8-bitters and multi-whatever

Also, some of the PC local net software could use the parallel and ethernet ports as well as RS-232 and bridge among them for a peer-peer net, or a client-server model using an external hub. Now there's a question, whether Interserver can handle multiple Interlink clients (one at a time of course); anybody ever try it? mike

Nova 4 has been claimed

The Nova 4 that I posted about needing a new home has been claimed. Thanks! I'm sure you'll hear some stories from the new owner in a couple weeks. -- David Griffith dgriffi at cs.csubak.edu A: Because it fouls the order in which people normally read text.

Wang 300 Calc --> 0/1 power labels

There's a less often used way of avoiding this problem.

[SPAM(date)] Re: What's the difference between an ARM1 and ARM2?

by stevew＠ka6s.com

Tony Duell asked about the difference between the two processors - here is what I found after a little google work; Steve The stuff below was brazenly copied from: http://www.everything2.com/index.pl?node=ARM2 "As soon as the ARM1 project was completed, work began on its successor, the ARM2, which later in 1985 became the first commercially available RISC processor. This processor was intended to correct some problems noted with the first design, and was aimed specifically for use in the Acorn Archimedes series of personal computers. While the ARM1 was a success as far as it went, there were some performance problems which needed to be fixed before it could be realistically used in the Archimedes. One of the key problems was a lack of hardware multiply support. This led to a software routine being used to do multiplication, using shifts and adds, which was "horribly slow", according to Steve Furber. This was fixed in the ARM2, by adding two instructions: MUL (multiply) and MLA (multiply with accumulate). These allowed the ARM2 to be realistically used for mathematical calculation, and very simple digital signal processing, in particular generating synthesised sound. Another issue which still affects most ARM processors even today is the lack of floating point hardware. Acorn decided to address this problem by adding hardware co-processor support to the ARM2, and at a later date intended to ship an optional floating point accelerator. Ultimately, the ARM2 FPA was never produced, despite demand from the Acorn user community: the first hardware FP came as an option with the ARM3 powered A5000, and around the same time a third party ARM3 and FPA upgrade was marketed by Simtec for all Archimedes computers. Finally, the design team noted that banking only registers R10 to R15 in fast interrupt mode was slightly over-frugal, and added R8 and R9 to that list. This increased performance of the very common FIQ by lowering memory accesses to stack registers. The ARM2 was manufactured at a slightly smaller fabrication size than the ARM1, 2.5?m as opposed to 3.5?m, had just over 25,000 transistors, and ran at 8MHz."

Computer rescue

Very, very nice haul. Whatever the expense was, it sure looks like you got your money's worth. Is this system going to be on display somewhere during VCMX timeframe? I don't know if it is going to live in the warehouse where it was deposited by the truck, but it sure would be fun to have a closeup view of the system, blinking lights preferred! ;-) Or, not, even. Congrats on saving a great collection! - Jared
