Someone here is selling Nexgen 586 CPU/Board sets. I was thinking of investing in one because I've never seen one before. Were there many made? Not classic I know, but maybe more obsolete than some 10 year old computers perhaps? Hans

Help: Identify DEC/Dilog Modules

It needs a special backplane. M7133 in slot 1, M7134 (MMU) slot 2, Slot 3 to 6 are modified for 22 bit memory. Slot 7 starts the regular UNIBUS IIRC. I have a few if you want me to check the DD #.

I just managed to get control of the machine while checking out a "Games" disk and I now have DOS 3.3 How can I transfer the Binary files (non basic) to my newly formatted disk. All it has is a HELLO basic program. (like INTBASIC and FPBASIC and D800 (?)) Thanks All.

Northstar Horizon

by edick＠idcomm.com

That's about the price range I remember too. OTOH, I used to get the Integrand box and, separately of course, the CCS CPU, CCS 64K DRAM board, and CCS FDC for about $980. Two of the Misubishi MB2894 (?) DSDD 8" drives cost $780, though, and the system still needed a dumb terminal. For that I normally used a Televideo 920, or, later, 910. Those also cost about $750 back then. It wasn't cheap, no matter how you turned it. With that combination, I was able to put out a computer system which had a decent display, decent performance, and generally acceptable storage for around $3k with a few bucks in my pocket if I shopped carefully. It was easier, of course, if the client already had some stuff, like a printer and a terminal.

Classic Computer Hardware & Software - Sealed Bid Auction

by bill_r＠inetnebr.com

I recently moved, and the living room of the old house is currently filled to the walls with stuff I regrettably can't bring along (go figure - 3 times the square footage plus a barn and a garage I didn't have before), so I'm hoping you guys will help me find new homes for it. To see pictures and descriptions, go to the following URL. It will take a few minutes because there are a number of items and the pictures are not small. http://incolor.inetnebr.com/bill_r/computer-sale.htm This will be conducted as a sealed-bid auction. High bidder takes the item. Bid by e-mailing your bid (minimum of $10 on each item, please) to bill_r(a)inetnebr.com (that's bill(underscore)r). Please include the item number, description, your bid amount, and your e-mail and snail-mail address and telephone number in each bid. Bids will be accepted through November 30th, 1999, although some items may close early if I receive what I feel is a reasonable offer and/or have not seen much interest in an item. In addition to the amount stated in the bid, the high bidder also agrees to pay actual packing and shipping costs, and insurance if desired, or to arrange to pick the item(s) up in Lincoln, Nebraska. Seller reserves the right to withdraw items from or add items to the auction at any time. Payment by cashier's check or money order will result in faster shipment. Payment by personal check will delay shipment until the check clears. All items are AS-IS, and no guarantee of any kind is made with regard to operability, suitability for application, safety, or completeness. Descriptions are as honest and accurate as possible; if you have specific questions about an item and are serious about placing a bid, please e-mail me at the above address and I'll try to provide additional information. This is all stuff I've collected over the years and no longer have room to keep - I'd rather not get rid of it, but at least I'd like to see it go to someone who will enjoy it and appreciate it. -Bill Richman (bill_r(a)inetnebr.com) http://incolor.inetnebr.com/bill_r - Home of the COSMAC Elf Microcomputer Simulator, Fun with Molten Metal, Orphaned Robots, and Technological Oddities.

Help with (Obsolete computers--a paper)

by dlw＠trailingedge.com

I've seen newspaper articles and such on this topic online but don't know if they're still out there or even where they were. Can any of you here help him out with some links or such? Respond directy to him at the address in the message. Thanks. ------- Forwarded Message Follows ------- From: GEngel039(a)aol.com Date sent: Tue, 2 Nov 1999 22:06:59 EST Subject: Re: Obsolete computers--a paper To: dlw(a)trailingedge.com Hi, thanks for responding! I am taking an introductory computer class, and need to do a two page paper and a 5 minute speech. We get to choose the subject. Basically, I am looking for brief information, such as environmental hazzards posed by discarded computers, perhaps an estimate of the number of computers being disposed of daily (monthly, yearly-basically I need one estimate to work with), what can be done with these "obsolete" computers to keep them from ending up in landfills (I noticed you were working with this), etc. I'm not looking for you to give me the information, I don't mind doing the research myself, as I find this an interesting topic. I just need maybe a few websites that may be able to help me. I appreciate any help you may be able to give me in steering me in the right direction. Thank you!

Northstar Horizon

by edick＠idcomm.com

The N* Horizon was a late entry in the S-100 market, and, though it was priced competitively with CROMEMCO and VECTOR GRAPHICS systems, it didn't come in at a lower price than component systems using boards purchased individually based on comparison-shopping for the best price/function tradeoff. As I mentioned previously, I used the SD Systems or CCS boards. Both of these CPU's included an on-board serial port which was used by the firmware as the console port. What's more, their FDC's handled both drive sizes, albeit in soft-sectored format only, straight out of the box. I don't remember the details of the comparison shopping ventures, but would not have used individually chosen boards or, in the case of CCS, board sets, if there were no price advantage. The CCS board set was always quite trouble-free, and the SD Systems memory boards were the only boards of theirs that ever gave me headaches, though that was seldom. The N* didn't work well with KONAN (SMD) or MSC HDC's either. I didn't investigate this full, however. It didn't work, well, on to the next one.

A sad day for DPT...

by bruce.a.lane＠boeing.com

Heck, a sad day for storage overall! Adaptec has swallowed up yet another customer-friendly SCSI adapter maker. See: http://news.cnet.com/news/0-1003-200-1425979.html?tag=st.ne.1002.thed.1003-2 00-1425979 While not directly related to classic computing, I know a lot of us use more modern systems for numerous duties, and I know I can't be the only one using DPT's 'legacy' products from the early 90's. Anyone care to wager what Adaptec will do to DPT's well-stocked FTP site, or their support of said legacy gear? Adaptec, from what I can see, is getting dangerously close to turning into the Micro$haft of the SCSI adapter world. (Kai, if you're reading this... I'm sorry. I know you work for MS, and I want you to know that I don't hold it against you in any way, but I think everyone on the list knows how I feel about Billy-boy and his Evil Empire). -=-=-=-=-=-=-=-=-=-=-=-=-=-=- NOTE: The views expressed are mine alone, and do NOT necessarily represent the views of the Boeing Company, its management or employees.
