Hmm, I have a pair of Mac SE's here, and was a bit surprised to find that one of them has signatures in the rear of the case, but the other one doesn't; does anyone know what dictated whether a machine had the signatures or not? (I was actually surprised to see signatures at all, I thought that went out with earlier models) Anyway, the one with signatures is a SE with a single 800K drive and 20HSC hard disk, last IC date I can see week 25 of 1988. There's also a sticker on the chassis saying July 30th 1988. The one without is a SE with dual 800K drives and a Quantum drive on a bracket (which was possibly added later), last IC date I can see being week 01 of 1988. In other words, what seems to be the later machine has them, and the earlier one doesn't. Possibly cases from different plants, where one had changed their tooling and one hadn't? Or maybe the "later" machine is actually an earlier build but has had a system board replacement (with the date sticker being the date of repair)? Curious, anyway... cheers Jules

Soviet line voltages

by derschjo＠gmail.com

I ended up with an Elektronika-85 (also known as the MS-0585)that was sold by a listmember a few weeks back. It's an uncanny clone of the Dec Pro 350/380 both inside and out. I'm just givingit a basic inspection at the moment and I'd like to test the power supply, I'm just unsure what voltages / frequencies it wants and there are no labels anywhere indicating what those might be. My research on the 'net indicates that it's likely to be 220/240V (in which case I'll need to get astep-up transformer), but I was wondering if anyone here had any first-hand experience with this sort of thing. Thanks as always, Josh

by LYNCHAJ＠YAHOO.COM

Hi!? There have been several requests for another round of the S-100 Bus Extender PCBs.? Since these are essential tools for any S-100 builder I think we should get some more.? We need 20 PCB pre-orders so I can make a manufacturing order. The S-100 Bus Extender board is ready for ?production?.? If you would like to get one or more of these very useful boards please do the new usual pre-order.? I will set aside your board so you get them as soon as they arrive. Here is a link to S100computers.com website with information on the updated S-100 Bus Extender board: http://www.s100computers.com/My%20System%20Pages/Extender%20Board/Extender%2 0Board.htm The PCBs will be $20 each as per the usual arrangement.? Shipping in the US is $3 for a single PCB and $2 for each additional PCB.? Shipping internationally is $10 for a single PCB and $3 for each additional PCB.? This is for the bare basics USPS first class postage with no tracking or insurance.? The builder assumes all risk of delivery as per usual arrangement. Please send a PayPal to LYNCHAJ at YAHOO.COM with the subject ?S-100 Bus Extender? and I will reserve your board(s).? Thanks and have a nice day! Andrew Lynch PS,? We are still doing another order for S-100 Buffered Prototyping board bus and have 6 boards in the queue.? If you would like one or more S-100 Buffered Prototyping boards please let me know.? The pre-order arrangements are identical to the others but please send them in a separate email so I can keep things straight on this end.

Hi! The S-100 80286 CPU PCBs have arrived and I have shipped all the pre-ordered boards.? The boards look great and the order has been a huge success!

cctalk Digest, Vol 122, Issue 20 - Re: Barrys collection - the free stuff

by johnwallace4＠yahoo.co.uk

One day I'll learn to type; till then I will just apologise from time to time for sending half composed messages (and using a rubbish email client). Sorry! > -- Vax 1000 BA-23 Note that it's possible (probable?) that this is an rtVAX 1000, with a KA620 CPU board, and possibly no mass storage in the BA23. The KA620 is closely related to the KA630 (MicroVAX II) with one small but significant difference. The rtVAX family (not to be confusbed with the ftVAX) were sold to run DEC's distributed realtime OS, VAXELN, which could be network booted (or boot from disk). Some rtVAXes had slightly cut down memory management relative to ordinary VAXes, a "feature" which meant they'd never run VMS. Some folk won't mind the distinction, others might. VAXELN is an interesting piece of software in its own right but doesn't seem to be in the VMS Hobbyist program. Regards John

Our county has an electronics recycling drop off in about 10 days. Some Sbus cards, maybe a CPU, maybe a graphics card or two (PCI). Is there anyone in the Northern New Jersey area that would want this stuff for free? Pretty close to NYC, too. -- David Strom -- David Strom dstrom at fastmail.net _______________________________________________ rescue list - http://www.sunhelp.org/mailman/listinfo/rescue

Hi folks, Just a quick note to remind you that DEC Legacy 2013 is next weekend in Sunny (well sometimes!) Windermere, UK. I've updated the website with some more details of the presentations. Registrations are up on last year and given the heritage of the attendees I think we are all set for a great weekend. More information on the website: http://wickensonline.co.uk/declegacy Regards, Mark. -- http://www.wickensonline.co.uk http://hecnet.eu http://declegacy.org.uk http://retrochallenge.net https://twitter.com/#!/%40urbancamo

[N8VEM-S100:1971] S-100 80286 CPU PCBs have arrived!

by monahan＠vitasoft.org

Hi All, I will do a detailed write-up on constructing/testing this board when mine arrives. For those wanting to get an early start, a reminder, be sure to use a mica insulator between the 5V regulator and the board (or as a last resort a pair of small washers) . You do not want the traces in that areaon the front of the board touching the heat sink/ground.
