I just spotted a Compaq portable 3 in a 1980 "flashback" scene of Psych. A useless observation, it had the expansion bay on the back. "Psych" High Top Fade Out (2009) Season 4 episode 7 There appeared to be something like a Commodore 64 driving a display on camera. the CP3 was not powered on. Not sure if anyone here had anything to do with a loan or elsewhere, or if the film company owned it. Jim

Can you read rx02 or rl02 disks ??

by system11＠bigpond.com

To all, Happy New Year and good luck in 2011. Being new to this site, I have some requests for help. Question 1. Anyone with a working pdp-11 with rx02, I have some diskettes I wish to recover data and programs from for use with Robert Supnik's pdp-11 emulator, can you make a disk image suitable for above to email me. I am happy to pay you to do this and return the floppies to me. Question 2. As above but 4x RL02 cartridges, but if you can get the images, you can keep the disks. If you have both rx02 and rl02 would save time and postage. For those fussy about copyrights I have valid licenses and full documentation for RT-11, TSX+ and S&H Cobol, but unfortunately no longer have a machine to read them. (Hindsight is marvellous) Thanks in anticipation, Royce Smith Southern Highlands, New South Wales Australia system11 at bigbond.com

Where to get VXT software?

by james＠slor.net

I have a DEC VXT 2000 that I would like to try out, but I don't have the software to host for it to load up the X environment across the network. Anyone know where I might still obtain the bits? Looks like the last version *may* have been v2.1g? Thanks! James

Wanted: X/PEX terminals

by legalize＠xmission.com

The recent discussion of VXT2000 reminded me of X/PEX terminals. I'm looking for X Window System terminals, particularly early NCD models before they switched to using PC keyboards. I have several NCD 19s, see right hand side of this photo: <http://manx.classiccmp.org/collections/cgm/sprawl4/dsc_0608.jpg> However, I don't have any of the color X terminals from NCD for that period. Also, I have *no* PEX terminals and this would be a very welcome addition to the collection of the computer graphics history museum. I have a number of small box type X terminals from NCD, Tektronix and IIRC even an HP branded one. They are from late in the X terminal marketplace where they all had become fairly identical: small rectangular boxes to which you attached a PS/2 keyboard and mouse and a VGA monitor. I can post a list of the exact inventory in the museum's collection if that will help avoid duplicates. -- "The Direct3D Graphics Pipeline" -- DirectX 9 version available for download <http://legalizeadulthood.wordpress.com/the-direct3d-graphics-pipeline/> Legalize Adulthood! <http://legalizeadulthood.wordpress.com>

Software wish list

by g-wright＠att.net

Hi, All I'm back at the grind trying to find a few old OS's The first is for my TEK DPO (WP 1210 Digital processing scope ) this is a 7704a scope with a P7001 Digital processor that connects to a DEC PDP 11/05 . It runs on TEK Basic (8" floppy or DEC tape}.. The official name is "TEK SPS Basic V02" There is also a system test disk. This uses a TEK 4010 Terminal for a display. The second is a Pertec Mini ?? coax system 4010 Don't know much about it other than it used coax to the dumb terminals instead of Serial.. (1/4 " Tape) The third is a OMS Zues 4 I beleive it ran cpm or mpm (5 1/4 disk) The forth is a Tek 4051. looking for the Tape images. The fifth is a Tek 4404 computer. Looking for the disks (5 1/4 floppy) I can handle most image files. Or would gladly pay for a Disk or tape. If I missed somewhere online, point me in the right direction Thanks, for reading this Jerry Jerry Wright JLC inc g-wright at att.net

Imaging a TK50 across the network

by sander.reiche＠gmail.com

Hi all, It is probably asked before, but I can't seem to find it in the archives. I have a MicroPDP up & running 2.11BSD but no spare TK50 tapes to make a backup of it, before I f*ck it all up :) I do have a lot of TK50s which weren't mine and they have data on it of which I do not know the status. They came with a MV3100 with VMS on it, which I am going to use eventually as well. So I'm not really willing to just scrap the data on those tapes. I'd like to make a backup-image of those across the LAN before I write anything else on it. How do you guys usually do it? # tcopy /dev/rmt0 to see what's on it # dd if=/dev/rmt0 bs=??? | rsh other_current_bsdmachine_with_lots_of_diskspace -l <user> dd of=vms_tape_file?.img bs=??? for every file on there? I didn't even know `dd' wouldn't cross EOF boundaries tbh (wasted my youth on C64s and Amigas :)). -- ~ UNIX is basically a simple operating system, ? ? ? ? ? ?but you have to be a genius to understand its simplicity. ~ dmr

CP/M: How to use old dischette?

by elazzerini＠interfree.it

Hi all, The reason why I'm interested in this topic is that I recently restored a Ferguson Bigboard I with its CP/M 60K. I'd like to try different programs that are contained in third parts diskettes, but they are of course in a different formats. I am using ANADISK to identify the format and sequence of sectors on disks and 22disk133 to try to read them correctly. Despite having read the definitions of the FCB manual on CP / M, I am finding difficulty in : 1) to determine the block size chosen for different disks; 2) Identify the value AL0 Unfortunately it seems that any further calculation is dependent on the size of the block that would seem a prior undetectable, and i'd need to try different values (starting from 1024,2048,4096 and 8192). Is it in this way? Some format i'd like to determinate: A xerox SWP diskette: SSDD 9,1024 sectors sequence 1,2,3,4,5,6,7,8,9 A MK-83 diskette: DSDD 8,1024 sectors sequence 1,4,7,2,5,8,3,6 Thanks for any helpful hint.

Tandata TD1100 dialer

by ard＠p850ug1.demon.co.uk

It took me a lot of work to discover this information, and I am not sure why it's so cryptic. But anyway... Some time ago I mentioned I had a Tandata TD1100 viewdata set on the bench. At power-on you get a dialing menu, the numbers for which are clearly stored in the battery-backed RAM. Dialing a number from the menu was easy (<menu number>#, for example 2#). But I could not find out how to stroe numbers in the menu, everything I tried got 'Please Try Again'. I am not suprised I didn't find the right sequesnce by trial and error. It is clearly designed to be impossible to get by accident. I fianlly found it by readign otu the firmware ROM (it is socketed, but I can assure you that desolderign a 24 pin DIL chip would have been trivial compared to the rest of it), writing a quick-and-dirty disassmbler for 6502 code (soemthing that took me most of yesterday (Newtonsday) afternoon [1]), and then going through the lisitng. [1] This would ahev been a lot easier if the 6502 data sheet I'd been workign from handn't been written by a boatie. There's a nice 16*16 table of the nmemonics, the rows and columns being numbered from 0-F. It turns out that the _rows_ are the most significant nybble, in other words you read it across, not down. The lables indicating this are in tiny type in one corner, and I missed them. So I had to move my table of mnemonics aroudn a bit. ARGH! My first guess, which turned out to be correct, is that it would use CMP instructions to identify wheter a typed character was 'acceptable' or not. So I searched the listing for these, and found a sequence of CMPs which seemed to do the right thing. I then spent some time figuring out what that routine does, and I finally got the sequence to load a number into the dialer menu. It is : Turn on 'program mode' with the switch on the back first and type : <menu position>*****<Number to dial># For exxaple 2*****123456# will store 123456 into the second position of the menu. Note that it's 5 '*'s. No fewer (or you get an error), no more (or you get spaces at the start of the number in the menu. If you do not turn on program mode, the entry is ignroed -- no error message. -tony

The D6.0 documentation has also been combined in a single PDF that is available on the MTS Archive at: http://archive.michigan-terminal-system.org/documentation/documents/MTSD6Do… Among other things the file D6.0-MTS-DOC.txt from April 1987 (a year prior to the release of D6.0) says: MTS is currently being run on the following computing systems: Amdahl 5860, 5870, 470V/8, IBM 3090-400 (with vector facility), 3081G, 3081D, 3033N, and 4361. In addition MTS has been tested on or was used for production on the following machines: Amdahl 470V/6, 470V/7, 5890, IBM 3033U, 370/148, 370/168, 370/158, 4341, and NAS 9060, and XL. The same file goes on to say: Machine Requirements MTS requires an IBM 370 compatible machine (including the 30xx machines) with at least two megabytes of memory and the following features: Floating Point Universal Instruction Set CPU-timer and Clock-Comparator Translation with 1M segments and 4K pages Conditional-Swapping PSW-Key-Handling Channel Indirect Addressing on all channels Clear I/O on all channels It will make use of the following features if they are available: Extended precision floating point Vector facility Direct control (limited use) Branch and Save Fast release on channels Invalidate Page Table Entry Common Segment Facility Other features are not used, unless user programs make use of them. The MTS file system normally uses IBM 3330 and/or 3350 compatible disks in any combination although it also supports older types of disks. MTS also provides support for the Xerox 9700 page printer, the Autologic APS-5 phototypesetter, and for both IBM and ANSI standard magnetic tape labeling/blocking and the normal IBM unit record equipment. >From D6.0-NEWSYS.txt: 1. The starter system requires a minimum of one 3270 terminal, one 3380 disk drive, and one 9-track tape drive. >From the D6.0-NOTES.txt: MTS can run under the 370 and 370-XA architectures. Under 370-XA, each task is limited to an address space of sixteen megabytes, but all real storage on the machine will be used to support virtual storage. MTS does not (yet) run run under IBM's ESA-370 architecture. MTS provides Named Address spaces, a facility similar to IBM's Discontiguous Saved Segment support under VM, to allow tasks to share preloaded programs and data. A program may be loaded into a Named Address Space (or NAS) at system IPL-time and then added to or deleted from a task's virtual storage as needed. MTS will use expanded storage as a high-speed cache to minimize I/O to DASDI. The cache is store-through; all writes go immediately to disk. However, disk reads will be satisfied from the cache if possible, thereby cutting down the number of real disk I operations required. Changed DASDI [in D6.0] to use "Read Device Characteristics" command to determine the size of the disk being formated. This gives us support for any disk supporting this command including: 3380s (Ds and Es have been tested; Js and Ks should work but have never been tested) CMS minidisks (untested) The old FBA disk support has been rejuvenated. MTS now supports internal 9370 disks (9335s have been tested; we have not tested 9332 support).
