WHY? (Was: What's the point of USB keyboards+mice)

For my first PC/XT clone computer, I built my own case. I put the?floppies and power switch on the front and all of the ports on the side (the expansion cards ran from side-to side rather than front-to-back). Much easier to get to the cords that way and there were no wir es sticking out the front. Bob

A little humor from my school

by fraveydank＠gmail.com

Some of you will find this amusing, anyway. This is a verbatim quote >from our *current* graduate CS handbook: The department?s computing facilities include Sun and Silicon Graphics workstations, SGI Crimson and SPARC servers, and high performance graphics workstations (SGI Indigo2, Onyx Reality Engine2). The Office of Information Technology has over 400 workstations for general student use and several high-end machines including a Silicon Graphics Challenge XL 20 processor system. UMBC?s Imaging Research Center also provides high-end graphics support including production quality input/output devices and production software (Wavefront, Softimage, and Alias). While these are cool machines, I did see some of them at VCF East this past weekend. I'm pretty sure the school doesn't have them anymore. I guess weeding out old info isn't a top priority. :-) - Dave

WTB: Signetics 2650 Evaluation board PC1001

by pinball＠telus.net

Does anyone have one of these animals? I am trying to reproduce an old video game that was based on it and figured it might be easier with the Eval. board. Thanks, John Robertson Vancouver, BC, Canada

Need a PDP-8/I Bootable DECtape

by michael.99.thompson＠gmail.com

The RICM has the processor of their PDP-8/I functional after replacing or repairing 38 Flipchip modules and the core stack. We have lots of Dectapes that originally held data from a PDP-11, but nothing that is bootable on the 8/I. We tried the TC01 bootstrap with one of the PDP-11 tapes. It moves the tape to the first block and then gets a TIM (Timing Error), so the TC01 and the TU55 is at least partially alive. Can anyone supply a Dectape that would be bootable on this 4k machine, or tell us the procedure for making a bootable Dectape? http://www.ricomputermuseum.org/Home/equipment/pdp-8-i -- Michael Thompson

[NO REWARD WHATSOEVER] Looking for IBM, ANSI, and Sun doc

by microcode＠zoho.com

I figured I should ask now while everybody is in a helpful mood :-) Does anybody have scans of any or all of the following? IBM 01. MVS/ESA Component Diagnosis and Logic: EXCP Processor (LY28-1477) 02. LY28-1487 03. LY28-1488 04. LC28-1166-5 05. SA22-7085-0 System/370 Extended Architecture Principles of Operation 06. SA22-7085-1 System/370 Extended Architecture Principles of Operation 07. SA22-7200 System/370 Enterprise Systems Architecture Principles of Operation ANSI American National Standards Institute ANSI X3. 74-1987 (PL/I Subset G) Sun UltraSPARC-IIIi Programmer's Reference Manual which is referenced here: http://hg.genunix.org/onnv-gate.hg/file/48f2dbca79a2/usr/src/lib/libcpc/spa… and here: http://download.oracle.com/docs/cd/E19683-01/816-1681/6m83631lh/index.html although without any pointers or links. I have the U/S IIIi User's Manual but this does not seem to be the one the above doc is referencing. No reward except my gratitude and promise to search my archives for my pals in need! However Al is making it pretty tough to have anything unique! Many thanks to Al for running bitsavers and everybody for contributing. I hope archive.org sticks around long enough for us to scrounge whatever is left on Sun but it's getting thin. I haven't been able to get to the open firmware site on playground.sun.com and the official site is running a business on openfirmware and isn't exactly giving out doc. So much for open. Thank you.

There is a keyboard, a mouse, a trackball, and a Wacom Inkling all plugged in and active using USB. How do you do that with only two ports? I use the trackball and occasionally the tablet. Another user uses the mouse and the tablet. All without unplugging and plugging the various devices... ->CRC
