Speaking of Flight Sim. love Mysteries at the Museum but misuse of HP PROP

by COURYHOUSE＠aol.com

I love this Mysteries at the Museum show but sometimes some of the pros they use are a bit off! FACT checking props on Mysteries at the Museum! Why is link using a 200 A or B HP audio Oscillator! there he is at a work bench with this HP thing and a set of bellows allegedly 1929 era. I laughed my ass off..... Ed# >from history... The Origin of the Link Trainer. Today in aviation history, on April 14, 1929, Edwin A. Linkfiled his patent application for his first Link Trainer, and what of HP first product? the 200a and the special one for Disney? 1938 * Work begins * HP invents first product * Oscillators for Walt Disney ====================================================== ok.... there we go! just can't be near 1929.. now I am sure some time Link Had or his people used early HP stuff... but not in the time frame as presented in 29 or neat 29.

Gould 32/77

by jnc＠mercury.lcs.mit.edu

> From: Jon Elson > we got an 11/45 used and ran RSX-11M with about 4 users on it, it > worked VERY well About when I first got to MIT ('74), they were running the main introductory programming course for CS students (6.031, for those to whom that means something) on an 11/45; it had (IIRC) about 30+ Decwriters hooked up to it. It ran a home-rolled OS called 'Delphi' (written in Macro-11, I suspect); the course covered assembler, Algol (compiled, I think - but it may have been interpreted, I'd have to check) and LISP (interpreted). ISTR that the response time on the machine was usually pretty good. By a very odd chance, some years later I got that very machine in a trade, and it became the main time-sharing machine (running Unix V6) for our group (CSR) at LCS (545 Tech Sq). We beefed it up with an Able ENABLE and I think 1MB of memory, and IIRC the optional Able cache for the ENABLE, and it was _quite_ zippy - I think 'mips' returned about 3.0, about as fast as the DSSR 11/70 on the other side of the 5th floor at TS. Of course, it didn't have the mass storage I/O bandwidth of the /70, but we were very happy with it. > of course, when we moved up to a VAX, that was even better! Heh. Give me an 11/45 with an Able ENABLE any day! :-) Noel

TeleVideo progress

by isking＠uw.edu

Hi all, I've posted looking for help with a TeleVideo TPC-1, and I've heard a lot of crickets - apparently this isn't a commonly held machine. :-) But I've made progress with it, which I want to share. When I first got it, the display would light up and ask me to insert a floppy. Doing so would promptly douse the display. I figured, 'power supply', and recapped the entire thing - after the venture of figuring out how to open the case! I found a post in netnews that strongly suggested TeleVideo had suppressed information about opening the case to protect their service centers' business.... It's an odd combination of 'push there, pull there and be bold', but I got it open. Recapping was a success, and the machine attempts to boot from disk 0 - and tries, and tries, and.... I figured that drive 0, being the most used, might have issues, but wasn't looking forward to pulling out the drive cage and swapping them as a test. But then I noticed that drive 1's circuit board was visible, and I rejumpered it to be drive 0 - and success, the machine booted into CP/M! Sure, I could just leave it as a single-drive machine, or swap the two and pray - but this is a restoration. I've ordered an exact, tested/guaranteed working replacement from ePay, and I'm going to have everything working to spec before I snap this thing back together. Yes, I'm having fun. :-) -- Ian S.

Gaming on old systems (was Re: Twiggys [was: Re: ka... ching!])

I am actively seeking lists of favorite games on all platforms prior to 1995. Specifically, things that require Windows and a Pentium and newer are out of bounds. I'm attempting to breathe some excitement into a retro-gaming meetup I hold a few times a year at our hackerspace. I'm already bringing the hardware - to date, Commodore PET, Commodore 64, Apple II, Atari 2600, PDP-8 (emulated for now), and curses-based UNIX games, and would like to add more platforms. I'm especially interested in any favorites that run on dumb terminals (I have numerous ones to bring in, and have a VT220 already in the collection). Yes, I know a bunch of games that run on those platforms. I'm looking for other people's favorites because that is what will stimulate interest in the meetups. I already bring my own favorites, but learning what other people remember fondly - tapping into their nostalgia - will be a big help. In bounds are any machines from the 70s and 80s that a) are common enough to lay hands on or b) have a reasonable emulator on modern platforms. I will probably add DOS games to the list, but that's not the focus at first - 8-bit microcomputers and minicomputers are at the top of the list. Emulation via simh is acceptable but I'll try to dig up the original hardware where possible. If you've played anything in the past 3 years, I'd especially like to hear about it since that speaks to enjoyment and replayability. If you like it, someone here will probably like it too. Thanks for any and all suggestions! -ethan

Where are the cctech archives before November 2014 ?

by w.f.j.mueller＠retro11.de

Hi, I detected that links I had to previous postings where invalid. Looking at http://www.classiccmp.org/pipermail/cctech/ I see that the archives before November 2014 are lost. When I look into the WayBackMachine I see https://web.archive.org/web/20141025062159/http://www.classiccmp.org/piperm… https://web.archive.org/web/20150103042513/http://www.classiccmp.org/piperm… that between October 25th. 2014 and January 3rd, 2015 some incident happened which wiped out the archives before November 2014. How comes that the 'classical computing' lost it's memory ?? With best regards, Walter P.S.: It's a bit astonishing to me that a list like cctech, which is in some ways about history, has lost it's own history, and even doesn't seem to care about it.

Gould 32/77 (was: NWA auctions)

by jnc＠mercury.lcs.mit.edu

> From: Brad H > the 11/45 is from around the early 70s right? First released in '72, if memory serves. It was in production for a _long_ time, though - no later model really replaced it (if you wanted a mid-sized machine with a lot of crunch), unlike many of the other -11's (e.g. /05, /40, etc). Noel

Any Kryoflux, Discferret, Catweasel, or other floppy flux images wanted

by spacewar＠gmail.com

Would anyone care to donate floppy disk flux-transition images for use in development of utility software and for regression-testing the same? It would be much appreciated. Images from "normal" floppy formats (IBM FM and MFM, e.g., TRS-80, IBM PC, or almost anything using 177x/179x/279x or 765/8272 family controllers) and obscure formats (DEC RX02, Victor 9000) would be welcome. I'd especially like to get IBM 23FD "Minnow" disk images, but I'm not holding my breath for that. If you send me any images, a brief description of what they might contain and/or what system they're from would be helpful. I don't need to be able to do anything with the content; I just want to verify that I can extract the content from flux images into sector images. If you send me any images that you don't want made public, let me know. Thanks! Eric

IBM 6715 / actionwriter "daizy" typewriter "RS232" port ??

by gerardcjat＠free.fr

I know it is a long shoot ! The IBM 6715 / Actionwriter was one of the last daizy wheel typewriter made by IBM Germany. ( said to be made to last at least half century, German design ;-) ) It has "kind" of a RS232 port on the back, I was unable to find any information on this port which was intended to support two "extremely rare" !!! IBM options one beeing a REAL RS232 port, the other some kind of display of the two last line typed. I wonder if someone has even connected this typewriter to a computer. It would be fun to use it like a "modern" TTY but I think the problem is probably that this typewriter expect a "lot of" (??) proprietary commands to set type spacing, margins, baud rate etc .... Any advice ?? Any help ??
