Here is what I use: For mild/moderate cleaning Simple Green works great. For heavy yellowing I use Purple Power which removes a lot of, but not all, of the yellowing (careful this can discolor metal). I use both with the Black and Decker Versa Pac rotary scrub brush with the soft brush attachment, if the case is removable, in the sink or driveway with a hose. Simple Green diluted 1:1 with water with a rag and Q-tips for cleaning the keyboard and parts of the computer near elecrical components that can't be hosed down or put in the sink as in step one. Goo-Be-Gone for spot cleaning of residue from stickers etcetera. Meguiar's Protectant as a last step.

Grandfather system RTE6/VM?

by holger.veit＠ais.fhg.de

I am working for some time now to get RTE-6/VM to run on simh. Note that this software is meanwhile available for free from HP, see image Z00701 RTE_6 Z007 RTE-6 RELEASE 6.2 FROM HP in Interex RTE/CSL archive 4030 at http://www.interex.org/tech/csl/RTE/submits4030.html (last contribution in list) What I need is a 1:1 disk dump of a bootable RTE-6/VM system (should be LU 2) to further debug the simulator. This might be produced by dumping the raw disk image into a HP1000 record (FMGR) file and then transferring this file via kermit to another host. This might result in a file that still has the common HP record separators in it, but I can remove such markup. A so-called grandfather system might be useful, but a working RTE where the above upgrade may by installed is probably usable as well. Anyone to help me with this? Thanks in advance Holger

ebay question

by jwest＠classiccmp.org

I have a couple questions about ebay/paypal, and figured some folks on the list here might know the "straight scoop". 1) If some seller sets up an auction as private (yet it still shows up on the listings) - the deal is that no one can see who bid on it, or who is currently the high bidder. In this set up, how can I be sure the seller isn't bidding on his own auction to drive up the price? He's taunting me I bet demmit! heh 2) Hypothetically, say I sell an item on Ebay for... oh... $2500.00. The guy could pay me via paypal, or he could send me a cashiers check. Does Paypal report transactions to the IRS? Or more importantly, if I sell items on ebay all year... do I have to track all that and report to IRS? Never really thought of it cause it probably isn't much money anyways. But I am curious if ebay and/or paypal reports to the IRS. Jay West --- [This E-mail scanned for viruses by Declude Virus]

Then I get three because I understood it, and can think of processors that do it -- and a few more because I've not only got some (MIPS R4600, R5K and R10K) but I know how to tell them what the best guess is (they have forms of branch instruction that can be tagged in assembler as "likely" or "not likely", to modify the internal branch prediction mechanism). The Pentium can do speculative execution as well, and one version even did a fetch of both branches, but only a pre-fetch, not execution. -- Pete Peter Turnbull Network Manager University of York

I would imagine the IBM 360/91 also did this. Steve Wilson (Burroughs Alum)

TRON...

by bpope＠wordstock.com

I just saw TRON again last night... Very cool movie IMHO. In the beginning of the movie it looks like Flynn is using an Apple computer to hack into ENCOM. There is also a scene where the heros are running through a huge room filled with mainframes. Does anyone know if these were real mainframes and if so, what kind are they? Cheers, Bryan Pope

Seriously old computers: Radio Research Instrument Co.

by wmaddox＠pacbell.net

While scouring the web for leads on classic computers, I came across a VERY interesing listing of items for sale, to wit: MINUTEMAN DIGITAL COMPUTER. General purpose synchronous, serial, digital computer originally used to solve inertial guidance problems. Mag disc memory 2688 words of 27 bits each. Clock speed 345.6K/sec. Pwr: 28V DC, and 115V, 3 Ph, 400 Hz. Mfr: Autonetics. DATA PROCESSOR. Includes tape reader, punch, and display. Mfr: Control Data 8090. DIGITAL COMPUTER. Cabinet mounted with memory core, and operating panel. Pwr: 115V, 60 Hz. Mfr: Digital Equipment. PDP-5. What I wanted was the PDP-5. I called these guys up, identified myself as a vintage PC collector, and and spoke to a gentleman named Doyle. Unfortunately, the PDP-5 has been sold. I inquired about the 8090, but Doyle didn't know immediately whether they still had it, and I wasn't prepared to make a serious offer for it. The 8090 is a variant or derivative of the CDC 160A, but that is all I know about it. Anyhow, here is the info for anyone who is interested: Radio Research Instrument Co., Inc. 584 N. Main St. Waterbury, CT 06704 USA Tel: 203-753-5840 Fax: 203-754-2567 http://www.radioresearch.thomasregister.com Look under "Test Equipment/Computers". Their primary line of business is secondary-market sales and service of military-grade radar equipment. Some of the stuff listed on their website is wild, and I'm sure you've got to have the approval of a few federal agencies to buy it... --Bill
