Looking for a copy of MicroPDP-11 Systems Maintenance Guide

by sander.reiche＠gmail.com

Hi all, Regarding the above topic from November this year, I was wondering if the mentioned guide (EK-MIC11-SG-001) was indeed uploaded to bitsavers eventually? If so, where can I find it? regards, Sander Reiche -- ~ UNIX is basically a simple operating system, ? ? ? ? ? ?but you have to be a genius to understand its simplicity. ~ dmr

HP 1000 software collection

by aek＠bitsavers.org

J David Bryan organized the contents of the tapes that I've read over the past ten years. The software is available for non-commercial use under an agreement between CHM and HP. A huge thank you to Mr. Bryan for doing this, since I haven't had the time to organize it. There are over 75,000 files, around 2gb. It should be finished uploading later tonight. http://bitsavers.org/bits/HP/HP_1000_software_collection

MTS should work on a 4331. >From the MTS Wikipedia article (http://en.wikipedia.org/wiki/Michigan_Terminal_System#Hardware_used): In theory MTS will run on the IBM S/360-67, any of the IBM S/370 series, and its successors. MTS has been run on the following computers in production, benchmarking, or trial configurations: ? IBM: S/360-67, S/370-148, S/370-168, 3033U, 4341, 4361, 4381, 3081D, 3081GX, 3083B, 3090-200, 3090-400, 3090-600, and ES/9000-720 ? Amdahl: 470V/6, 470V/7, 470V/8, 5860, 5870, 5990 ? Hitachi: NAS 9060 ? Various S/370 emulators All of the information that follows is included in the tar.gz archives available at Bitsavers.org. 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).

Scanned versions of the Caranahan and Wilkes book and a number of others related to the Michigan Terminal System (MTS) are already available online in the Hathi Trust Digital Library: http://babel.hathitrust.org/cgi/mb?a=listis;c=1889583521 A more limited set of PDF documents that doesn't include the Caranahan and Wilkes book is available from U-M's Deep Blue digital archive and the PDF Archive at Bitsavers: http://deepblue.lib.umich.edu/handle/2027.42/79570 http://www.bitsavers.org/pdf/univOfMichigan/ The MTS PDFs in Deep Blue and at Bitsavers tend to be of a higher quality since they aren't scans of physical books. -Jeff

Sometimes you just have to cut a trace or two and/or add a jumper or two; for example here's how to convert a standard SIMM for use in an HP LJ: www.keycruncher.com/blog/2003/12/14/making-standard-simm-s-work-memory-upgr… I did the same sort of mod to use standard SIMMs to expand memory in my Toshiba T3100e.

Anyone heard from/of Curt@atarimuseum.com?

He and I were engaged in an email exchange that suddenly stopped, and I hope nothing unpleasant has befallen him. Thanks -- Ian
