MicroVAX I update

by witchy＠binarydinosaurs.co.uk

Hi folks, Gave my 'new' MV I a good going over this afternoon and apart from the fact it has a pair of M7135s (MV I Datapath according to Megan's field guide) and came with a sodding great big (and heavy) Tek 4109 screen/keyboard/tablet/pointer there's nothing too exciting in there: M7551 & M8067 memory boards M7957 DZV11 mux M8639 RQDX2 to run the RD52 and RX50. This means there's still a couple of slots to add in a DEQNA should I want to get it on the network. It'll have acclimatised by tomorrow so can anyone give me the pinouts of the PSU so I can check voltages before I run the whole lot up? I'll trudge through the snow to dig out my MVII techref just in case they're in there, but if anyone knows off the top of their head that'd be great :) -- Adrian/Witchy www.binarydinosaurs.co.uk - possibly the UK's biggest online computer museum www.snakebiteandblack.co.uk - ex-monthly gothic shenanigans :o(

oddball televideo problem

by jwest＠classiccmp.org

I have a system that does an "autobaud" when you hit return to log in. If I hook up a VT220, it works at 7/1/E, 8/1/N, 7/1/O, etc. etc. no problem. If I hookup a Televideo 950, hitting return gets no response at all. This is NOT a DTE vs. DCE problem, because the televideo does work with the same system on a different type of serial port. I was thinking something might be brain damaged with parity generation/checking on this terminal. Is this a known issue of TV950's? About the only way I can find out whats going on is to dig out my datascope and see the start data & stop bits between the two when hitting return and see what is different. Any thoughts?

Emulators of Classic Computers

By age 11 wrote my own OS for a Soviet PDP-11 clone. But then I'm Soviet, so that should explain it. We Soviets are obviously superior. :-))))))))))))) My girlfriend is 18, but she is very mature for her age. And I have absolutely no fear about letting her around my classic computers since she has the highest respect for my work. We are both pagans and these computers support our pagan work. For her to screw up the computers would be equivalent to betraying her Goddess Herself. I will teach her how to use my operating system (a classic version of VAX UNIX, other people in my group run other classics OSes too), she'll have a terminal on her desk in our command room just like I do, and the policy of no pee seas with Weendoze being allowed in the house will be entirely reasonable and acceptable to her because it's the enemy's operating system. Other people on this list keep whining about their wives conflicting with their classic computing, but I will have a female partner using these great systems together with me in our pagan work, which has brought us together in the first place.

Young generation of ClassicCmp (was Re: Emulators of Classic Computers)

My gf is a witch (1st degree priestess, working on 2nd degree) and will also have a lot of "unusual" stuff to teach to our future children. They will be really fortunate to have a two-parent thoroughly pagan family. The way pagans raise their children is VERY different from the common American Judeo-Xtian way. A few months ago the Coast to Coast AM radio talk show featured two girls who were reading ancient Sanskrit and seriously getting into its teachings at ages 2 and 4. MS P.S. Anyone here a regular Coast to Coast listener? You may have heard me on the air, as I have called in a few times. Hoping to be a C2C guest some day.

New Computer Museum in Austin

by jrkeys＠concentric.net

Earlier this week I was told that Dell (Mr. Dell not the company) had purchased a very large old warehouse and was going to turn it into a vintage computer museum of his own. I was also told that he had sent out a team to locate old hardware and stuff for him. Anyone in the Austin area know about this?

physical tape drive emulation? ts-11?

by brad＠heeltoe.com

This may seem silly, but it occured to me this morning (musing about how to boot an old 11/34) that I could use a device which would pretend to be an actual tape drive. There are lots of tape images out there (on the web) in the form of big disk files. It would be nice to be able to turn one of my pc's into a "virtual tape drive" by plugging a cable from the pc into a TS11 controller... Has anyone ever seen such a device? seems like it would not be that hard to build (he said, never having looked at the interface between a physical tape drive and a controller like a TS11). I hope to find an old RL01/2 drive around the Boston area (anyone?) but even when I do it seems bootstrapping will be an issue. Even if I grab one of those Dilog controllers which talk SCSI I'll need some way to load up the drives initially. It's just that those 9-track drives are *really heavy* :-) any comments appreciated! -brad

Emulators of Classic Computers

by aek＠spies.com

even if we save the raw files, how will we view them in 50 (or even 5) years? -- The short answer: You won't -- The reason will be no one will have preserved the data describing the file formats, since it is "proprietary" And you won't be able to simulate the systems, because the data needed to simulate it is proprietary also. -- Two example systems I can think of right now: Schematics or chip designs done on products by Daisy Systems (dead, dead, dead) or Mechanical and electrical CAD designs done on Calcomp electronic drafting systems based on the Xerox D-machine.

Emulators of Classic Computers

by palazzol＠comcast.net

Hello, I just wanted to take a chance to plug MESS: http://www.mess.org/ It is an open-source, multi-system emulator for old computers and game consoles, based on the MAME codebase. If someone is interested in writing an emulator of an old system, this is one way to go. There is definitely a learning curve, but there are preexisting modules for many microprocessors. If anyone is interested in exploring this, feel free to contact me directly. Thanks, -Frank
