Need help with installing PDP-8 4k Disk Monitor

by michael.99.thompson＠gmail.com

For some reason the misbehaving TC01 controller on the PDP-8/I at the RICM decide work yesterday. Possibly due to the low temperature in the RICM warehouse. We took advantage of the situation and formatted and tested five DECtapes. Following the procedure in Appendix-A of the 4k Disk System Monitor System Disk System manual, we ran the DEC-D8-SBAF-PB 4k Disk System Monitor System Disk System Builder. We told it that the 8/I system does not have any disks or a high-speed paper tape reader. The System Builder wrote the Monitor, Loader, Command Decoder, Directory, and Storage Allocation Block Maps to the DECtape. We were able to enter the DECtape bootstrap program and boot the 4k monitor. The next installation step is to add programs to the DECtape. We continued with the procedure in Appendix-A.4. When the console displayed an ^ we entered a CTRL-P and then told the terminal emulator to send DEC-D8-PDAD-PB Disk System PIP-DF32 tape image. After sending about 1,500 characters the 8/I started echoing the characters from the tape image on the console and the command processor tried to use the input as commands. Somehow, after receiving 1,500 characters the 4k monitor switched from paper tape input mode to command mode. I am not sure if this configuration can be duplicated on one of the emulators. If someone could try the monitor installation and subsequent loading of programs from a real "Teletype" it would be interesting to see if it works. If it does work, then maybe we need to add the reader control circuitry to the 20mA/RS-232 converter that we are using to connect a PC to the PDP-8/I. Any advice would be appreciated. -- Michael Thompson

Help identifying ICs?

by snhirsch＠gmail.com

I have a sizeable number of Intersil 0.3" 14-pin DIP ICs (plastic package) with a part number "3-200-5" and a 1978 date code. Google turns up about 500 hits - all of them those obnoxious Chinese sites none of who have the chip or any data about them. How do folks work around all the "we find you chip fast, enter RFQ here" web sites? Steve --

cleaning up after the move.

by ba600＠ncf.ca

It's been a long while since my last post, and I should have cleaned up before moving rather than after. But I have a pile of monitors and external SCSI boxes that I'm not interest in keeping. Is there any interest or should these go to the recyclers. Apple monitors these came with the 2e all the way upto the LC's I think I only need to keep one or two so there are several spares Also older CGA and VGA monitors a few older terminals a pair of IBM PC 500 servers and 3 AS/400 9404s -- Collector of vintage computers http://www.ncf.ca/~ba600

VCF Archives Fund Raiser Sale

by sellam＠vintagetech.com

Dear CC Talkers and VCF Fans: The Vintage Computer Festival is currently securing funding for operations and storage of the VCF Archives for the next 6 months. As such, the VCF is conducting a limited sale of select items of the VCF Archives. As the VCF Archives pretty much contains everything, and due to current time restraints, the sale will be held as such: contact me (Sellam) with a wish list, and I'll indicate which of your requested items I could offer with a description and offer price. We can haggle out a deal from there. As my funding needs surpass my ability to deal with many small transactions, I am necessarily limiting the sales to items of a value of at least $250. This does not mean I will attempt to jack up the prices, but I would prefer to make single transactions that have a value of $250 or more. I apologize for the unorthodox nature of this sale but I am in an unorthodox situation and this is the surest way I know to raise the funds necessary to secure the archives. Please e-mail me with your wish lists directly. Thanks! -- Sellam Ismail VintageTech ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintagetech.com Whatsoever a man soweth, that shall he also reap...The truth is always simple.

VintageAppleNMore Etsy Store

by slandon110＠gmail.com

What drew me to it was the .20 cent listing fees.. They only take a 3.5 percent cut of your final value. Pictures are free and you can list as much as you want. The listings last 3 months too which makes it even better. Feel free to chime in your thoughts on my pricing. Im listing a ton of vintage apple.

Opus ISA SparcCard

by paulyandy＠yahoo.com

Bernd, Greetings! I have a mysterious ISA card and after researching, I found an old post from 2007 which contained a conversation you were having regarding an Opus ISA SparcCard.? I'm curious if this is what I currently have. Do you happen to know of any online information about getting this working?? I was going to recycle it but it seems a shame if it is a bit of history and of unique functionality. Any help is most appreciated and thank you! Paul Anderson

Apple 1 and Altair set new records at auction

by lsprung＠optonline.net

Greetings everyone, I just wanted to bring the following 2 items to the lists attention. I'm surprised I've seen no discussion about the record setting prices from the recent Auction Team Breker sale last week where an Apple I sold for about $640,000 and an Altair 8800 reached $16,000. WOW! Does anyone have any insights to these? Do you think these prices were due to auction excitement or new global interest in the value of collectible computers? http://acn.liveauctioneers.com/index.php/auctions/auction-results/8714-apple -1-computer-sells-for-640000-at-auction-team-breker

SIMH images to Zip Disks

by fraveydank＠gmail.com

I have a bootable 100MB RSX-11M image in SIMH that I'd like to blast onto a Zip disk and boot through my CQD-220. I'm running a build on SIMH that's essentially identical to my machine, so it should be straightforward, but when I try to boot my disk, I get a "not bootable" response from the ROM (the activity light on the Zip drive does flash momentarily, so I know something is going on, but it doesn't look like it's taking enough time to actually seek anything (and when I boot through the bootstrap provided by the CQD-220 ROM, I get a HALT at 000002, which tells me it's probably getting all zeroes). I know at least some of you boot your -11s off of Zip disks, probably with similar cards. What am I missing? As far as I can tell, the SIMH disk image format is a headerless binary blob, but it doesn't look like I'm getting to the point where that even matters yet. - Dave

by jgessling＠yahoo.com

I wonder if that was originally from Tri-Valley Growers.? a very large agricultural Co-op based in Modesto (nearby) that went bankrupt in 1999.? They were heavy VAX and later alpha users and would show up fairly regularly at BAYVAX meetings back in the day.? Not sure about the graphics thing though, can't remember them talking about that, but it's been a while.? Just for fun I googled for "tri valley growers vax" and was surprised to see how many people out there have that on their resumes.? Pretty fertile ground for computer people as well as fruit.

I like to run an older Cisco multibus router with my old computers, just to keep it all 'vintage' and I'd like to find a spare router if anyone has one. Any of the older Cisco 'multibus' AGS routers would be of interest. I'm in the UK, but would pay for postage from overseas. Thanks.

P112 kit for latecomers

by dgriffi＠cs.csubak.edu

I'm now ready to take orders for P112 kits from people who didn't get onboard the Kickstarter project. For a complete kit (board and all parts that solder or plug into it), the cost is $200 to addresses inside the US -- $215 outside the US. If you want one (or more) please email me with your Paypal address so I can make up a proper invoice. Alternatively, I will accept check and money orders. If you want Terry Gulczynski to build and test the kit for you let me know and I'll get that set up. If you're outside the US and want this service, you can pay the inside-the-US price. I'll ship the kit to Terry. He'll charge you for his services and ship you your board. If you want to order a GIDE board at the same time, he can do that too for you. He'll also sell you the GIDE board by itself if you want to build it all yourself. -- David Griffith dgriffi at cs.csubak.edu A: Because it fouls the order in which people normally read text. Q: Why is top-posting such a bad thing? A: Top-posting. Q: What is the most annoying thing in e-mail?
