Looking for information about TEP FTI990, Eyring PDOS

by iamcamiel＠gmail.com

Hello everyone, Over the course of the past few days I've made a few repairs to a TEP FTI990, a TMS9900 based industrial microcomputer built on eurocards. I've now got it to the point where it boots and runs Eyring's PDOS operating system. I have a description and pictures of the system here: http://vaxbarn.com/index.php/collection/35-tms9900/69-tep-fti990, and an account of the repairs I did here: http://vaxbarn.com/index.php/collection/35-tms9900/70-tep-fti990-repair I have a copy of PDOS version 2.4C, as well as a PDOS programmer's reference manual. I am looking for additional materials: TEP and PDOS manuals, and floppies with additional programs. I'd like to get in touch with anyone who has some knowledge of these systems. Kind regards, Camiel Vanderhoeven

I'm up in Kamloops but even at the cost of gas (about $120 tghere and back) I'm tempted to go down and pick it up if it has not already happened. Failing that, There's a fantastic place at 304 Victoria drive that will accept the machine if you can't find a home for it. I can vet for them as their specialty is older machines. -John B. >IBM 5160 system >IBM 5151 monitor >IBM clicky keyboard. > >Dual floppy with hard drive, but the hard drive is erratic, perhaps a stiction issue. >Also some extra floppy drives and untested hard drives. > >Mentioned this last year, it's still available, but may soon end up in scrap if it's not taken.

help reading 9 track tape

by jecel＠merlintec.com

A student at the Physics Institute at the University of S?o Paulo (Brazil) reimplemented the Manchester DataFlow machine from the 1980s using modern FPGA technology. His goal is to evolve the project so it can be used for current applications. His advisor was at Manchester at the time of the project and brought a 9 track tape written on a PDP-11 which includes the Pascal sources for a compiler for the DataFlow machine. There is no equipment locally that can read the contents of this tape, but it would really help the student's project to have access to these sources. I imagine this stuff might be interesting for other people as well, so perhaps mailing the tape to someone on this list who can read it and put the content online would be the best option? -- Jecel

The XDT> is the eXecutive Debugging Tool and is similar to ODT. The X is a command to do a crash dump. There are not many MCR commands available in RSX11S, but one that you should try is TAL which if it was included in the system sysgen will display all the installed tasks and their status, ATL shows which tasks are active. RUN task name will execute a task that is installed. The most interesting thing that you might find in the system, if it was included is a task called RSDV1H which displays a live picture of the memory organization and system operation similar to RMD on a RSX11M or M+ system. RSX11S was designed to be a memory resident real-time priority driven multitasking system. It is booted from a disk but really doesn't have a file system unless it is included in the sysgen and then it only does block I/O type operations. Nonresident tasks can be loaded by a task loader if that capability is sysgened in. This all sounds pretty limiting and it is but still RSX11S can do a lot when needed. Over 30 years ago, I helped create a system that read data from 8 commodity exchanges & a news wire feed in various formats, then sent DECnet data packets to 10 PDP-11/23s running RSX11S. The 11/23s each had 20 VT100s hung off each one (using DLV11Js and DZV11s) with each commodity trader getting customized screens of data in real-time. The goal was to get data to the traders faster than any other commercial service. News headlines scrolled across the bottom of the VT100 and the trader could request specific stories which were stored in a RMS-11 Indexed file back on the main server which was an 11/44 run RSX11M. The RSX11S systems had no disk and were downloaded the OS over the leased data line running at 9600 baud (fast for the day). The 11/23s ran re-entrant Macro-11 code in 256 Kbytes of RAM (OS, programs, & DECnet). Best Regards, Mark

IBM PC XT free for pickup, Vancouver, BC area.

by hilpert＠cs.ubc.ca

IBM 5160 system IBM 5151 monitor IBM clicky keyboard. Dual floppy with hard drive, but the hard drive is erratic, perhaps a stiction issue. Also some extra floppy drives and untested hard drives. Mentioned this last year, it's still available, but may soon end up in scrap if it's not taken.

FS: DEC Rainbows, PRO 350s, VR201s, LK201s, etc.

by rjlorenzen＠q.com

I have decided to sell off my collection of the above on eBay. I need the money and space and don't want to move them. Just search for my user name, fortran00 (that's double-zero). I am starting with components and will move on to parts, complete systems, docs, software, etc. as I complete an inventory and testing. There are multiples of everything. Deals outside of eBay will be considered, but not for items actually up for auction, as this violates eBay rules. I have a larger discussion of what is available under the listing for Rainbow system units. Everything is tested before sale, but of course I can't guarantee future performance.

Looking for Eyring PDOS for TMS-9900

by iamcamiel＠gmail.com

If anyone happens to have a copy of the PDOS operating system for TMS-9900 systems, I'd like to know, and hopefully arrange some sort of transfer; I have a TMS-9900 system on eurocards, built by the german company TEP. It was not working when I got it, but I painstakingly debugged a bunch of problems out of it with my trusty logic analyzer. I've now got it up and running to the point where it tries to load the OS from a 5-1/4" floppy disk (79 tracks, 16 sectors, 256 bytes/sector). The BOOT EPROMs contain a bootloader for PDOS, and I have a PDOS manual, but not the operating system itself. PDOS was made by Eyring Research Institute, Inc. Thanks! Camiel Vanderhoeven
