Emulex UC17/UC18 SCSI-Controller in PDP11/24

by GOOI＠oce.nl

Hello Andreas, you might try leave off the leading "17" of the address, thus enter @760334 1 <LF> but I am not 100% sure.

by swtpc6800＠comcast.net

There is a lot of 5 Addmaster paper tape readers (new in box) for sale on eBay. No bids yet, ends April 9th. Item number: 7505437498 I would buy one but I don't need five of them. These look like the ones Data I/O uses to use for the PROM programmers. Michael Holley

Registry for terminal DA responses?

by msokolov＠ivan.Harhan.ORG

Hello again, As I was working on my terminal application (people usually say "terminal emulator", but I avoid that term since I'm creating a new terminal rather than emulating one made by someone else), the following question came up: there is a control sequence called Device Attributes (DA) whose generic form CSI c requests that the terminal send another DA sequence back to the host to identify itself. Each DEC terminal, for example, has a unique DA response. This is what the ECMA 48 standard (equivalent of ISO 6429) says: 8.3.24 DA - DEVICE ATTRIBUTES Notation: (Ps) Representation: CSI Ps 06/03 Parameter default value: Ps = 0 With a parameter value not equal to 0, DA is used to identify the device which sends the DA. The parameter value is a device type identification code according to a register which is to be established. If the parameter value is 0, DA is used to request an identifying DA from a device. My question is: does anyone know if such a registry exists and where can one apply for a DA code assignment? TIA, MS

HP 2100S @ $5K?

by jwest＠classiccmp.org

HP 2100S on ebay... looks nice, but.... Seller lists it as "mint" and "may never have been used" - uh, no. Not even close to "mint/never been used". I'd grant it "good", maybe even "excellent"... but mint/never used? nah... The ad says it's fully functional. That suprises me... I hope they didn't run it for hours to test it what with the power supply filters visibly all turned to dust and sucking up inside the machine. Lastly.... $5K? Surely they aren't worth even half that - even if it was truly "mint". I'd put actual (non-Ebay) value at around $400 (maybe I'm biased, I have a few)... and I'd put Ebay closing prices for a 2100 anywhere >from $1500 to $2000 (actual values I've seen recently). But opening bid $5K? I just can't imagine that. The contents (memory, I/O cards) are unknown.... I predict that it won't get a single bid.... until the guy relists with a starting bid of around $1000. If I am wrong, then I really need to clean up and refurb a few 2100's and put them on ebay. Heck, if my wife sees a $5K close, she'll force me to. Jay

I still do this in my Kapro 4/84. In a pinch 1.44media will work fine if the media select hole (not write protect) is filled. Fortunatly I have a box of 720k media. Allison

Antikythera device on History Channel Ancient Discoveries program

by vcf＠siconic.com

Just saw a wonderful program on the Antikythera device on The History Channel. The program is called "Ancient Discoveries". The UK listings indicate the program will be aired there on June 17 and 18: http://www.thehistorychannel.co.uk/site/tv_guide/full_details/Ancient_histo… Oddly, I couldn't find it on the American History Channel pages but then I didn't search thoroughly. I checked Netflix but they don't seem to have the Antikythera episode available. -- 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 ]

Here is my web page on using 3.5 inch drives with SWTPC 6800 systems but the information is the same for all classic disk controllers.

VCF Midwest 1.0 Exhibitors needed!

by vcf＠siconic.com

There's still more than 6 weeks to go until VCF Midwest 1.0. That's plenty of time to put together an exhibit for the event. So far we only have 3 exhibitors, and Pat is started to get nervous. I told him that people usually wait until a few weeks before to submit their exhibit entries, and so in case you forgot, now is the time to submit your entry! We've already got a couple great speakers lined up (still updating the pages but you can see the first speaker's bio up now) and more to come. It's going to be an excellent event. So please run on over to your nearest web browser and fill in the exhibitor form here: http://www.vintage.org/2005/midwest/exhibit.php Don't wait until it's too late!

Nice computer museum in Sao Paulo, Brazil

by vcf＠siconic.com

If you're planning to go to South America anytime soon, here's a great computer museum to visit: www.museudocomputador.com.br I'm impressed! There is actually quite a bit of computer history activity in South America. There's another computer museum in Argentina as well: http://www.comsto.org/ The images are currently broken for some reason. However, this one has been around for years and was started by a kid who first contacted me several years ago and I've watched him grow the thing into a full blown organization based out of his university. I'm planning a South American nerd tour at some point. Maybe next year. I actually have relatives throughout South America so it'll be a dual purpose trip ;) -- 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 ]

by pat＠computer-refuge.org

So, one more part I need to get my DIY 11/34 functional, I need a DL11 for its console port. Since I aparenly was outbid on the one I was bidding on on ebay, I thought I might see if anyone on here has one available for a reasonable price.
