Hi folks, does anyone have a specification of the frontpanel colors used by DEC? I need information (RGB or CMYK value or pantone name...) about the dark green used on PDP12 and LAB-8/e frontpanels. I need the correct color for a restauration project. If anyone has further information, or the ability to check his frontpanel colors against a color chart... Would be very good. Best wishes, Philipp :-)

free: Tektronix Microlab I with complete docs

by cluno＠gmx.de

Hi Kurt, I contact you in regard to the Tektronix Microlab I. Do you still have it? If it's gone, do you know to whom? Is there any documentation available? I'm asking this, because I don't have any manual about it and need it for repair of Tek 7854. Please get in contact with me. Best regards, Christian Lehnert ----------------------------------------------- People, I recently bought a Tektronix Microlab I on eBay. It was sold as is, and in fact does not work. If anybody wants to take a stab at fixing it, you can have it. It is some kind of combination trainer/emulator. It has RS-232 and audio in/out to be used by the monitor program for loading programs into RAM. It looks like a microprocessor trainer: hex keypad, LED display, buttons for stepping through and starting and stopping the program. It can support a variety of different processors via personality cards. The card that is in there is for the TI TMS9900. Good luck finding other personality cards. They definitely were produced. When it is powered up, it shows different things on the LED and never responds to user input. I have made no effort at further diagnosis. Who knows, it might just be a power supply problem (linear, I think). It comes with complete documentation on microfiche including schematics. If somebody is interested in fixing it, it's free. -kurt -- Der GMX SmartSurfer hilft bis zu 70% Ihrer Onlinekosten zu sparen! Ideal f?r Modem und ISDN: http://www.gmx.net/de/go/smartsurfer

Relatively Early Computer Generated Art (1963)

by Apergy＠aol.com

Hello, This is my first post. Several months ago, I purchased a limited edition (12/50) photographic print of computer generated sine waves that was executed by Efriam Arazi in 1963. Arazi is considered to be a pioneer in leading edge computer graphics. I believe that the work was created by Arazi at MIT. Might anyone within or without the CCTALK community shed further light onto this work? Thank you, Randy In a message dated 10/23/2008 1:07:33 P.M.

I can't figure out how you define "monitor". Nor can I. It's clear (I hope) that the thing I use on my workbench with a raster-scanned CRT and a composite video input is a 'monitor' by any normal defintiion. It's equally clear to me that the DEC VT100 is not a monitor, it's a terminal (although it contains a monitor). But there are plenty of grey areas between them. > > Is it a raster-scan CRT?

That would be the definition I would assume you're using. If so, then the SAGE displays fit: those are direct view tubes that can display both vectors and characte rs, and the character display is a Charactron. Esactly. -tony ------------------------------ Message: 2 Date: Wed, 22 Oct 2008 20:38:39 +0100 (BST) From: ard at p850ug1.demon.co.uk (Tony Duell) Subject: Re: CRT displays [was: computer graphics in the 1950s] To: cctalk at classiccmp.org Message-ID: <m1KsjXX-000J12C at p850ug1> Content-Type: text/plain > > >vector representation and *that* is sent to the monitor.

That matches my impression as well. There is a DDCMP implementation in there as well. I wonder if the TLK and LSN programs are compatible with the ones on RSX. Someone asked about compatibility between phase III and phase IV, which Paul Koenig answered. I have another question, though. As I've read it, phase III nodes can talk with phase II nodes, just as phase IV can talk with phase III. But can phase IV talk with phase II? Since DECNET/8 is phase II, this is somewhat interesting... I doubt I'll have time to look more into this any time soon, but unless someone else manage to get this working I definitely will try it sooner or later. Could anyone put up the files for convenient access with ftp?

Well...one without deflection plates is rather difficult to use as a vector display, but that's a matter of complicated and unconventional driving electronics more than a matter of possibility proper. (Or, I suppose, one could use electrostatic deflection with the deflection plates outside the vacuum envelope, but that gets interesting in other ways.) But, that aside, if you want to use that narrow a definition of CRT, then no, characters are never sent to any CRT, Charactron or not; it's all voltage levels. I suppose you could view the voltage levels sent to a Charactron's pre-mask deflection electrodes as an encoding of a character; this point of view has some justice to it, since you could equally well say that a serial line doesn't carry characters, just voltage waveforms - but in that case you can view the relevant inputs to any CRT that's displaying a character as an encoding of that character, so it's really a question of which point of view is most useful. But I think we already got an explanation upthread that basically said it depended on software's view of it, making it more a question of design intent than anything else, since either "graphics" or "character" can be pressed into service as the other.... /~\ The ASCII Mouse \ / Ribbon Campaign X Against HTML mouse at rodents-montreal.org / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B ------------------------------ Message: 6 Date: Wed, 22 Oct 2008 20:25:45 -0400 From: Steve Robertson <steerex at ccvn.com> Subject: FS: How To Design Build & Program Your Own Working Computer System To: cctech at classiccmp.org Message-ID: <1224721545.17212.5.camel at bart> Content-Type: text/plain Thinning my collection of collectible books.

Compatibility is one phase up, so Phase III understands II, and IV understands III, but IV->II isn't supported. It's possible that someone did implement that; it wouldn't be all that difficult. But for example DECnet/E does not. I just checked... the message code for the Phase II init message is in the definitions file, but it isn't mentioned in the routing layer code so the state machine for handling that message is absent. paul PS. I noticed that the pdf/dec/DECnet directory on bitsavers.org has some Phase II and some Phase III docs (not clearly differentiated -- the 1978 docs are Phase II, the 1980 ones are Phase III). But there are no Phase IV docs there. I know they exist elsewhere; having those copied to bitsavers would be a good thing. ------------------------------ Message: 14 Date: Thu, 23 Oct 2008 11:26:51 -0400 From: "John Floren" <slawmaster at gmail.com> Subject: Re: OT:Humor What people think their stuff is worth To: "General Discussion: On-Topic and Off-Topic Posts" <cctalk at classiccmp.org> Message-ID: <7d3530220810230826s6935423eh419d888dfaa10f65 at mail.gmail.com> Content-Type: text/plain; charset=UTF-8 On Thu, Oct 23, 2008 at 10:17 AM, Zane H.

That matches my impression as well. There is a DDCMP implementation in there as well. I wonder if the TLK and LSN programs are compatible with the ones on RSX. Someone asked about compatibility between phase III and phase IV, which Paul Koenig answered. I have another question, though. As I've read it, phase III nodes can talk with phase II nodes, just as phase IV can talk with phase III. But can phase IV talk with phase II? Since DECNET/8 is phase II, this is somewhat interesting... I doubt I'll have time to look more into this any time soon, but unless someone else manage to get this working I definitely will try it sooner or later. Could anyone put up the files for convenient access with ftp? Johnny

New Hardware Available Soon! ... yet oddly ontopic!!!

by zmerch-cctalk＠30below.com

Yes, it's a shameless plug, but no it's not for my hardware. An individual by the name of Ken Pettit has designed a new piece of computer hardware called NADSBox - it's centered around simple portable file storage for the Tandy Model 100/102/200/NEC 820x (Kyocera-OEMmed) laptops that allows you to use an SD card to be used as a (dang big) floppy drive - and preserves the DOS file structure so you can easily transfer files from the SD card to your Winders/Mac (and I'll assume Linux, but it's not specifically mentioned) machine. Here's a press release on the unit: http://www.club100.org/nadsboxoverview.html And the user manual: http://www.club100.org/nadsboxusersguide_v10.pdf More info at: http://www.club100.org/ The inventor has several built and are slated for a 1 November 08 ship date, and if you [pre]order before 1 Jan 09, you'll get it for a cheaper price. Now... they're not cheap, at the preorder price of $150 & $10 worldwide shipping, but these things really are designed for the customer - they come with a 512Meg SD card with a built-in USB port so if you don't have a media reader, you won't have to buy one! Lo & Behold, tho - if that's not big enough, the NADSBox will support 16G SD cards! See the webpage mentioned above for more information on this *very* interesting piece of hardware for the Model 'T' laptops! Oh, and no, I'm not dead... yet anyway. My current employment situation is working on changing that in short order... but at least I'm employed. Laterz!

Tru64 5.1 ISO

by alexandre.laguejacques＠gmail.com

Hello all, Does anyone here have a copy of Tru64 5.1? I need to get the last version that supported the Turbochannel architecture (i.e. DEC 3000 AXP and friends) and 5.1A and 5.1B have dropped it if I understand correctly. I'd take care of the licencing of course... I just need an ISO or something. Thanks! - Alex

RTS-8

by chd_1＠nktelco.net

Anybody here have direct experience with RTS-8? I have a PDP-8/e, some digital and analog I/O cards and have toyed with the idea of trying to get RTS-8 running to control something (not sure what exactly). I think DECnet for the PDP-8 requires RTS-8 too. -chuck
