Real time video software for SGI computers

by mspproductions＠gmail.com

Hello all, I know that SGI machines are well know for high end 3D graphics that are not real time (Jurassic Park, Forrest Gump and the like. But was there ever any real time 2D/3D graphics programs for title generation to replace a stand alone Chyron unit for making opening/closing titles and lower 1/3 graphics? If so what system would be the best to use, I was thinking an O2 since it is small and has a low power consumption along with standard composite video output. Thanks, -- Matt Patoray Owner, MSP Productions KD8AMG

CDC 603 tape drives an dtCyber

by aswood＠t-online.de

The tape drives are from a 3000 system. I do have an original cdc 170 series console and it would be a big deal and a nice project to get the console and the tape drives connected to dtcyber, since I lost almost any hope to get a real cy17x or 18x. I'll be back home tomorrow and have a detailed look at the peripheral controller. Fortunately I do have a lot of spares. -- Andreas > Am 12.08.2016 um 15:59 schrieb Paul Koning <paulkoning at comcast.net>: > > >> On Aug 11, 2016, at 10:27 PM, aswood at t-online.de wrote: >> >> I do have two original CDC 603 tape drives with controller, but to be honest it would be quite a challenge to hook them to a modern system. > > 603?

Channel to PCI-e interfaces have been built (out of FPGAs) and hooked up to DtCyber. If it's some other type of channel, the same sort of answer would apply; none of those old channels are all that complex. > > paul > >

HP to acquire SGI

by cliendo＠gmail.com

I don't know about now, but SGI used to have a lot of Govt contracts and a lot of oil companies as customers. HP buying that also means they now have the ears of those customers when their solutions are old and they need to migrate to new equipment. I predict a lot of late model Irix equipment coming into the used market place.

5150/5151 Video Card??

by COURYHOUSE＠aol.com

sad when you think of all the cards that have been scrapped over the last 20 years for early PC Ed# In a message dated 8/14/2016 10:55:54 P.M.

For example, the "monochrome composite" is probably just luminance, blank and sync (VBS), whereas the "color composite" is the complete CVBS signal. I suspect that setting either of the two composite modes probably disables the output at the DE-9. It would be interesting to see what other combinations of switches produce something useful. Of course, this is all wild-hare speculation on my part, as I don't have anything like this card sitting in my hellbox. FWIW, Chuck

Front Panel - Update. - PDP=8/i and PDP-8/l - Bezels - PDP-11

by jnc＠mercury.lcs.mit.edu

> From: Rod Smallwood > Please register interest in ... PDP-11 panels It will depend on price - will they be the same as the PDP-8 panels (since they are so similar)? If so, can you remind us of the pricing, please? If not, any estimate? I assume you'll eventually be doing all of them (/35, /40, /45, /50, /55, /70 - both variants), but the order will depend on interest? Do you have a /20 panel scan/measurements, to do that one too? If there is any interest in /05-/10 panels, I have one and can scan it. I can't recall any other models with front panels? (Well, the /74, but IIRC there are none of those extant outside museums - although people might want some for simulators.) Noel

5150/5151 Video Card??

by cctalk＠ibm51xx.net

"should work fine u got rca and vga on that card might not be colour but it should work" Nope. Looks like a CGA card. It may also run in monochrome mode if you set the correct dip switches. The composite output can be used w a std TV set.

can anyone identify this terminal keyboard and pcb?

by COURYHOUSE＠aol.com

Well the frogs never were usable as a async ASCII terminal.. for some reason I think they were intended for IBM... The white later ones with detachable large keyboards definitely were for IBM and were used with a cluster terminal controller if memory is correct... if they were ASCII were sync not async? My memory escapes me at this point except for the fact none of us could use them and we call scrapped them! In a message dated 8/14/2016 3:36:00 P.M.

It was plus or minus 2. After using the monsters for an hour or so you had to go walk outside until your own vertical hold settled down. I imagine anyone who easily got seasick could never had used them at all. mcl

Hi Al - if they are itt courier was after my days of buying scrap there. I am looking for the old green terminals we used to call green frogs and would scap as fast as we ended up with them... now as a memento some of wish we had saved one of the old evil things... also looking for ITT asciiscope with the amber screen and the acoustic coupler on the top.

I bought the pcb, which has "C8080" on the sn label so I'm guessing it's Courier. Quite unusual with build-in modem. Will be dumping the eproms soon, hopefully some text strings in there. The seller ripped the terminals apart years ago for the 8080s and didn't rember the make/model, only that the case was two-tone. He got a pretty penny for the crappy probably dead Keytronic foil/foam keyboard ($80) Weird thing is it looks like a Lear-Sieger pcb design, with the Molex power connectors and the color/font of the markings on the silk-screen.

Yes Al, That is a green Frog! Cool! glad at least one still exists... I am in hopes there is still in one of existing in one the aux buildings here... I should display some Courier stuff. the later model was all while and had a detachable keyboard. We had a surplus electronics dealer would try to sell them to unsuspecting college students as terminals to be used with DEC system on campus... as I remember they were for use with IBM systems. ITT ASCIISCOPE was a good old self contained ASCII terminal and modem ALL UPPER CASE... in the early 80s sold them fast as we could get them... I liked UPPER CASE TERMINALS ---- QUICKER ---LESS WORK WHEN YOU DO NOT HAVE TO SHIFT! All the electronics scrappers and the few of us that dealt in computer stuff would go to the ITT sales... One of my best things was the palate loads of power cord that were new . I bid and got and sold to Bill Godbout... - ah the early 80s! I met Bill at a computer show in san Jose as I remember run by John Craig that had the 59 el Camino ( I think I have the name right? correct me!?)) I saved I think 100 figuring that was as many as we would need for awhile... Courier also had the contract to make the first McDonalds point of order terminals all of us scrapped lots of those too.... did anyone save one? You never know what was going to be at a Courier scrap sale... tools, pcbs terminals, cable on the wood reels... This was an interesting era and the early 80s I think I hauled lots of scrap... at the end of 79 started the business with 100 bucks and an empty van. sold surplus dg and dec stuff piecemeal and some interdata and what ever I could drag in.. Once I got the HP-2000 timeshare system that was the real game changer... it put us in the hp parts biz to support our own system and then 83? 84 became HP PC dealers still sold 2000 and 1000 stuff and designed boards for them.... got into the 3000 line ... I suspect the board you have Al , if courier, with the plug in modem, was surplused after I was going to sales... all I ever got there were the while IBM ones and the green frogs.... the ASCIISCOPEs that were floating around town may have come surplus into the market but just slightly before i was going to auctions there or they were just some off lease stuff from some of the lease companies that floated into consumer circle and we would end up buying one every once in a while In a message dated 8/14/2016 2:45:35 P.M.
