Bad nicad for the CMOS, It's loosing a bit here or ther and checksumming. That forces a bios error. I had two like that, replaced the nicad and Viola!

CPU design at the gate level

by ajp166＠bellatlantic.net

From: John Allain <allain(a)panix.com> To: classiccmp(a)classiccmp.org <classiccmp(a)classiccmp.org> Date: Thursday, November 01, 2001 10:55 PM Subject: Re: CPU design at the gate level >>Not to mention relays->tubes->transistors->RTL->... > >Would Transistors enter in to the picture as RTL? RTL Resistor Transistor Logic. Think very simple, basic gate is the NOR, power hungry and SLOW. The basic two input NOR is two transistors and three resistors. I have a fair collection of RTL (914, 900, 923, MC7xx) from the '67ish time frame and have built DMMs and the like using them. Allison

EISA - was VLB SCSI?

by technos＠nerdland.org

Easy. Just replace the bios battery. Prolly a lithium button cell the size of a nickle in a holder near the BIOS, if I remember right.

*Free* stuff

by kdavis＠ndx.net

I have the following stuff available for free. But you got to come and get it. I'm in the SF Bay Area (Mnt View). The systems are known to work unless listed otherwise: DecWriter II BA23's BA400 Intergraph BA23's Nice BA23 style Qbus cases with cool lights and key PRO350 -w- P/OS Boots. Was VAX Console. Have Docs. ~30 5.25 SCSI Drives Take one or take them all. 7470A Plotter Small Dec Corp Cab Has 11/23 logo. Holds 3 BA23's or one BA213 Protracer BBJ -w- Postscript Cart Makes large printouts. Have manuals and extra supplies DecStation 5000/200 Pizza Box. Should have docs someplace also. VaxStation 3100's 2 non-working Pizza boxes. May be able to get one working from both. HP Apollo 700 Pizza Box and Monitor Sparc 1 Pizza Box and Monitor RX50 Compat Drives Got a box of these. They are non-dec but are compatable. They are 1/2 height, black, new in bags. One or two to a customer. Apple II+ More powerful than a Apple I. Kirk Davis (kdavis(a)ndx.net)

value of classic DEC machines?

by mhstein＠usa.net

Whoa! 50 bucks, and three years ago?!? Put it in the price guide! That means my copy of Ahl's MORE Basic Computer Games has got to be worth at least $100... I'm outta here & off to check into eBay, but before I go, 'cause I like you guys I'll offer it here first at $49.95; 84 (Count 'em!) FABULOUS games for your personal computer! Start haggling <g> Speaking of you guys, just curious: is this an all-male hobby? No members of the fairer sex here? And Ethan, ain't heard back from you; you want these AIM manuals or what? mike --------------Original Message------------- Date: Wed, 31 Oct 2001 22:26:44 -0800 (PST) From: Ethan Dicks <erd_6502(a)yahoo.com> Subject: Re: value of classic DEC machines? I heard that three years ago when I tried to haggle for a copy of David Ahl's BASIC Games book at the Dayton Hamvention. They guy said "I can get $50 for it..." I asked him if he could, what he was doing at Dayton and why didn't he just sell it on eBay in the first place. Needless to say, the negotiations did not proceed smoothly. ;-) - -ethan

Cable and connector source

by mcclure3＠home.com

I've received a couple SGI Personal Iris' (4D/25 and 4D/35) that I'm trying to resurrect. After some hunting, I've gotten that elusive keyboard and mouse for these guys, but no keyboard cables (the 2x PI's take DB9, the 3x's 6 pin mini din). I'm want to make cables, but haven't found a local source for the necessary parts. Does anybody have any suggestions for an online source? Thanks, Don McClure Bel Air, MD

CPU design at the gate level

by mhstein＠usa.net

Not to mention relays-> tubes (valves for tony)-> transistors -> RTL->... Oops, I see someone else remembers the 914; thanks, Peter. ------------Original Message--------------- DTL -> TTL -> LSI -> FPGA, the gates are the same, just the wires got smaller and the way one manipulates them changed.

Heh... depends on the mainframe. The CDC-6600, the world's first supercomputer, was for many years rated as having a mine-hour MTBF... turned out that was because a counter was oveflowing after 9 hours of ticking away, and only under one particular operating system (SCOPE). But even under the more-stable KRONOS operating system, the field engineers typically took it down for an hour each morning. Periodically, they would polish the platters on one of the disk drive units (in the early 90s, we used to kid about using Lemon Pledge to cure stiction, but they drives *really* did get polished), while smoking a cigarette. Ok, I'm drifting away from reliability, so I'd better cut & run. -dq
