Safe is totally in the hands of the user. Cyanide is used in gold plating and is quite safe assuming stupidity is not part of the equation (i.e. let's see what it tastes like.) Navel Jelly does a great job of disolving the rust, and that is what it was intended for. Before using though, I wire brush off the heavy rust deposits and use navel jelly sparingly as the next to final step ... the final step is cleaning :).

wang professional computer

by jwest＠classiccmp.org

Yup, the one someone pointed out on ebay is exactly the one that I got recently (except mine has dual floppies and a hard drive). Note that the auction on ebay does not include the monitor (and the Wang monitor is proprietary). So if anyone here does win that auction, I know where a monitor and cable can be obtained pretty cheap, but only for a short while. The local surplus guy tends to pitch things that don't sell after a while. Jay West

That depends on many things. An emulator for a PC might be a microprogrammed archetecture for a PDP-5 which is a sequential logic machine. With real logic you have to deal with mudane and annoying things like two registers accessing a single bus. From my point of view doing a classic in FLGA is convenient as your not tied ot a PC but it's still more of a software exercise than real random logic. >As someone on the list has mentioned, it's really the old peripherals that >are the interesting bit. That because you have to interact with the physical world. Often that requires much more than a bit of logic to fly. Allison

VCF Build-It-Yourself Workshops

by sellam＠vintagetech.com

Just a quick note to let everyone know of the workshops we've added to the VCF this year. These workshops feature vintage computing kits that you build yourself, guided by the people who designed the kits. So far we've announced workshops for the XGameStation Pico Edition run by its designer Andre' LaMothe, and a COSMAC Elf 2000 (as featured on the cover of Nuts & Volts last month) run by its designer Bob Armstrong. Very soon I'll be announcing a third workshop run by Vince Briel to build his new Replica-1. These workshops are an excellent way for people who have always been interested in hardware but never had a practical environment for experimenting to pick up some new skills from top notch engineers, and some nice new toys (that you build yourself!) in the process. To read about the workshops, go here: http://www.vintage.org/2006/main/workshop.php There is a registration button for each workshop on its respective page. Payment is via PayPal (from your account funds or credit card). The workshops are scheduled at different times so the really adventurous can go to all of them ;) Vince's Replica-1 workshop will be going up very soon. A full VCF update will be coming out this week, with the current speaker schedule and more information on the first Vintage Computer Film Festival. Remember, Woz will be there, along with a bevy of other early Apple employees and founders for our 30th anniversary celebration of the birth of Apple. I'd also like to see some more exhibits get registered :) E-mail me with any questions you might have. -- 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 ]

couple of things

by rtellason＠verizon.net

I saw some mention in here about old HDs and such -- if anybody's in need of the ribbon cables to hook those up with, either pin-type or edge-connectors I have a pile of them. I also saw mention of a "Spinwriter". If somebody's looking for one of these, I have one sitting in a storage unit, though I will need some money to change hands for the owner of said unit to allow for its removal... -- Member of the toughest, meanest, deadliest, most unrelenting -- and ablest -- form of life in this section of space, a critter that can be killed but can't be tamed. --Robert A.

TRS-80 Model 16 hard drive questions...

by derschjo＠msu.edu

I just acquired a TRS-80 Model 16. It came with an external hard drive; model 25-1025, labeled as a "Tandy 10 Meg Disk System". It's a considerably smaller unit than the usual TRS-80 hard drives I've seen -- it looks like it would normally hold a half-height 5.25" MFM drive. Unfortunately, the drive enclosure is empty. I'm not well-versed in the area of TRS-80 drives, so I have a few questions: - Is this drive actually compatible with a Model 16? The limited info I've found seems to hint that this was for a Tandy 2000 or 1000 system. - If it is compatible, what kind of drive goes in the enclosure, and where can I find the proper cable to connect it to the Model 16? (The enclosure has a 20 pin "Data" and a 34-pin "Control" connector on it, looks like a standard ST-506 configuration, while the Model 16 has a single 50-pin connector.) - If the drive isn't compatible, anyone have a compatible one for sale/trade? :) I'd like to try to get Xenix running, I have the installation floppies -- just need something to install it to. I actually work with a guy who ported the Xenix kernel to the Model 16 back in the day, I thought he'd get a kick out of seeing a running system again... Thanks, Josh

Strange modem...

by aliensrcooluk＠yahoo.co.uk

Hi all, Just had a box come today. Inside are around 32 discs from CU Amiga and Amiga Format. I plan to catalogue them along with my other Amiga CD32 stuff during this week (I have the week off). Also in the box is a 56K (Data/Fax/Voice) modem, manufacturer is unknown. It simply states on the front end... "56K V.90/K56 flex" ... with more data on the bottom of the kit: "FCC No.: H52PT-3020 Data: K56 Flex/ITU-T V.90 & ITU-T V.34 MNP 4/5 & V.42/ V.42 bis Fax: G3 14.4K/14.4K Send/Recieve Voice: Simultaneous Audio/Voice & Data; Full-duplex speakerphone mode Power: AC 9V/1A Made in Taiwan" On the front it has two sockets for a mic. and a speaker to be plugged in along with 9 lights for: RD TD CD OH AA HS DTR MR PW I think I know what most of them mean. On the back it has an on/off switch, a power socket, a parallel port style socket (I have necessary cable), line socket and phone socket. I assume the line socket plugs into the phone connection socket, but what's the phone connection for? To plug the phone/fax line in?? I also have Active: Netconnect CD's V2 & V3, so having software to go online shouldn't be a hassle - I just want to upload and download stuff from Aminet (site for storing various Amiga files, utilities, games, patches and more) Regards, Andrew B aliensrcooluk at yahoo.co.uk

QIC 80 drive needed

> he happened to drop that he had a A/UX tape that he could not read as his tape > drive had "gone goo" It turns out to be A/UX 1.1 (!) I really hope he didn't discover this by attempting to read the tape. If so, he now has goo on the tape, and it will be extremely difficult to recover. FWIW, I have an image of A/UX 1.0, made in the days when the only way to get a copy was to go over to Bubb Road with a disc and have the original A/UX group clone it for you.

Sipke de Wal, xgistor.ath.cx, and SC/MP emulators

by ajwills＠paradise.net.nz

Hi everyone, I have been looking for Sipke de Wal's SC/MP emulator and of course found the note about his death in 2004 (http://www.classiccmp.org/pipermail/cctalk/2004-May/041480.html). Looking at the fragments of his website still available in the internet archive and on Google, I see he had a lot of interesting pages and downloads many relating to old computers and processors. There are still many sites on the internet that link to his website that hasn't existed for 2 years now. It seems a pity that all that work has now disappeared when the storage requirements and bandwidth, to maintain such a site, are quite modest. I would be happy to host a copy of his site if it could be reconstructed. I've reconstructed his SC/MP webpage (but still don't have a copy of his emulator). So a number of questions: - Did anyone here download anything from his site that they've still got (webpages or files) ? - Does anyone have contact with his familiy ? - Did anyone know Sipke well enough to know whether he would approve of the resurection of his website? Any help appreciated. Tony.
