Actually, mine was maroon, although the slipcase was gray; and as for "Not yet a classic," the pub. date was of course 1984. You'd be welcome to mine if I still had it, but I don't....think....

NOOOOOOOOOOOOOOOOOOOOOOOOOOOO!!!!! Stupidity Strikes Again!

by dseagrav＠bsdserver.tek-star.net

While moving the 11/34 to a more lighted area, I broke the power switch off the back. Now it doesn't power on. I need a WHOLE NEW POWER SUPPLY! Damn! I hate myself sometimes! That was a Stupid, Stupid, Stupid Mistake!

I used to work for DEC and DEC didn't sell ALPHA they sold the fab unit that does alpha. It's cheaper to have some other silicon foundry make the part to your spec. WD, intersil, AMD and Harris have over then years made parts for DEC that were designed by or for DEC. DEC plans to keep cranking the Alpha for bet your business systems than PCs have fallen short for. In the mean time I'm running a few old VAXen to remind me how much better an OS VMS (OK, OpenVMS) is. Allison

Needed: rom for Model 100

by transit＠primenet.com

Hi folks. I picked up a Tandy Model 100 laptop computer from a local thrift store a few days ago, for about $9. So far so good, but it doesn't have any ROM's in it (both sockets on the bottom of the machine are empty) When I switch it on, then off , the "Low Battery" light flickers, but that's all (the LCD stays blank) So, are these ROMS (which I think I need) something I can still order from Tandy (without paying an arm and a leg)? Thanks in advance (Oh, and I saw, but didn't buy, an Amiga Joyboard . . .) ------------------------------------------------------------------------------- Charles P.

> I just passed on the optical mouse and some keyboards for the Sun's. Passing on the optical mice or keyboards (type 3 or 4) is no great shakes. However... Passing on Sun optical mouse pads for type 3 or 4 mice is a crime punishable by death. They are unique _two_ color pads (the horizontal stripes are a different color from the verticle ones) that Sun does not make anymore (contrary to Sun Direct's sales people, the pads they sell are for the normal type 5 mice). In short, the things are getting quite rare. > I will > be going back next Saturday to pick up some other things I will see if they > still have them.

I remember when I wouldn't take a 286. I needed POWER. Like a SERVER. How 'bout a 486??? THAT WOULD LAST UNTIL THE 21st CENTURTY TOO!!! IT COULD RUN WINDOWS 3.1 with NO RAM ERRORS!!! And then when upgrading to Windows 95, I remember the guy there specifaclly falling down laughing, resulting in purchasing 16MB of RAM (Then at $10 a MB), to add to the 12 I had, along with a 486 DX/2 processor. I doubt that the 432 would actually take it. But I think that Intel aimed it at the wrong market. The Digital Alpha (Recently aquired by Intel, with it's RISC... yes, RISC technology) has had some success, with 600 MHz of power in a single chip and x86 "translation software" written by Digital. Also, there is a version of Windows NT 4.0 made ONLY for Alpha's, so the translation software is not used there. Microsoft writes programs like Internet Explorer for Alphas, but they're usually "a month late". Intel might have just bought it to stamp it out, but my guess is they're aiming to do something with the RISC market, they could be attempting to lower the Alpha's power down to H/PC levels and then WINDOWS CE. Maybe they'll take the 300 MHz version, that was avaible in 1995. If Apple can get 150 Mhz into a handheld, why can't Intel? But back to classics. Would the 432 be capible today if it were given a second chance? One last thing. I remember something about a huge warehouse filled with classics. Has anyone heard since? Ciao, Tim D. Hotze

Help Identifying RAM Chips

by allisonp＠world.std.com

<Wrong. For a while (in the early 90's) I subscribed to a magazine called <Defense Electronics. The military had things like 50ns RAM available then <They are way ahead in many areas; they can afford to (or used to be able to <anyway) throw money at things, and they often got first dibs. fast parts... keep this in mind: Good, fast, cheap, pick any two. In 1982 NEC and Intel sold 1kx4 (2149), 4kx1(2147) and 16kx1(2167) these were static mos parts that were anywhere from 35ns to a slow 70ns. They were widely available and about 7-9x the cost of the 4116 16kx1 dram. The problem was that '83 brought 64kx1 parts that were as cheap as the 4116, faster than the 4116 but were about 270ns-Tcy/200ns-Tcas. When your building a system the 4164 (8 of them) used roughly 240ma. the same memory using the super fast 2167 (32of them) would eat a whopping 2.16 Amps! Speed costs! It would also produce more heat. In late '83 I built a system using a 8088/8mhz with 256k of 2167s besides being amazingly fast. However 128 of those 2167s tended to heat up the place and their cost was $768 compared to $128 for the fairly new 4164 and the $96 for the very new 41256. Also using the newest 256k part would fit 4mb of ram where 256k of static parts fit and still use less than half the power. By 1990 32kx8 static rams were in the sub 30ns region. Drams were fairly fast for page mode but their requirement to have the address stuffed in in two pieces will add time to the ability to access in exchange for power savings, pins and packing density. Dram was never as fast but usually their density was the win. For the current generation of 200mhz and faster systems cache is barely able to keep up. look at the cost of 16mb of dram compared to 512k of fast cache ram. Allison
