I don't recall the excat values, but I got from a digital osciloscope, the following values: HSYNC: 28kHz VSYNC: 76Hz I have a mono monitor with HSYNC at 15kHz and VSYNC at 50Hz, which I was able to hack (!) in order to sync to the above values. I use a simple transistor buffer to convert from the ECL output to the 75OHM load of the monitor. I can give you further details on this if you want.

Supnik simulator for PDP11 mods (Was RE: PDP-11 emulator available)

by classiccmp＠mrynet.com

The recent interest for simulators/emulators on this list has prompted me to share publically the modifications I've made to the Supnik 2.3d simulator. It is available at: ftp://ftp.mrynet.com/pub/operatingsystems/simulators/sim2.3d+BB1.tar.gz Others who have already seen the modified work from me will have known this file as "sim2.3e.tar.gz." I've changed the distribution file name to prevent confusion with any official distribution that might perhaps follow from Mr. Supnik. There are regular (daily) minor changes to this as I clean it up and verify portability to other platforms. My interest in making modifications were for the same reason I've seen posted about the Supnik emulator: limited serial line support. Below is a summary of my work. Please email me any impressions, suggestions, requests and additional modifications. Kudos to Mr. Supnik for his extremely understandable and workable simulator. Cheers, -skots --------From the top-level README-------- From: Scott G. Taylor September 4, 1999. This is the Supnik Emulator for the Nova, IBM 1401 and DEC PDP 8, 11, and the 18b family PDPs 1, 4, 5, 7, 9 and 15. A directory exists for each of the models where an executable is created. (Except for the PDP 1, all the 18b CPUs are handled by the pdp18b executable coding). Current copyright information is contained in the file COPYRIGHT. The original copyright and documentation are contained in the file 'doc/simh_doc.txt'. Additions to the original Supnik 2.3d distribution: A utility program called `xtapeutil' has been added to the utils/ directory. This program allows you to interactively read and write tape images in the format used by the emulator. You can create tapes from individual files, or from "tape log" mapped images. The generated images have been tested extensively and found to work with all bootable tapes for RSX, RSTS and UNIX operating systems. It is also currently being reworked to aide in transferring real-tape data to simulator-format images, as well as handling labelled real- and simulated-tapes. Summary of modifications: The only modifications to the original source code are in the PDP-11 simulator version. With the exception of reorganisation of code into discrete directories for each simulated processor version, no other code has been modified. The only exception is a small modification to allow adjustment of the CLK timing in simulators which utilise a clock (in common/scp.c). Additionally, a structure of makefiles, compatible with BSD and GNU make, has been added to facilitate simulator builds. The PDP-11 code was modified in the following ways: o Addition of a 4-line DL-11 driver (pdp11_dl.c). o Removal of the stddev KL11 code. The console KL11 functionality has been assumed by the pdp11_dl.c DL11 code. The console line, however, can be reimplemented by defining -DUSEKL in the pdp11 Makefile. o Work-In-Progress on a 4/8-line DZ-11 driver. o A utility program, called 'netline' has been created to allow the simulated DL-11 serial lines to be accessible via TCP TELNET protocol. See README_pdp11 for more details. Building the simulators:

VT220's available in Kansas City

by mmcfadden＠cmh.edu

I have 3 VT220's with keyboards that are available. I'm not sure the keyboards are vintage VT220 but they are DEC. 2 VT220-AC white screen 1 VT220-BC green screen They are not in great shape they were manufactured in 1985-1986 and have been in use in our microbiology lab. They work!!! If you pay shipping and packing they are yours. If you are close we can work out other means. Mike mmcfadden(a)cmh.edu

Old plasma display

by stefan.boss＠gmx.net

Hello I have an old Matsushita plasma displays (from a Compaq PC I think). Do you have any information about this (or a similar) display... any datasheets about data communication or the power connector pins??? The display has the numbers MD400F640PD5 7.0.13 C:60963 I'm very glad if you could help me... yours sincerely, Stefan PS: I'm a student from Switzerland and I might be interessted to write a assembler-program with my microcontroller system (MC68HC11G5) for the display.

FT/S: Commodore 1902A monitor only

by mtapley＠swri.edu

All, A friend of mine is looking to dispose of a spare monitor he picked up. It is a commodore 1902A (sic?) monitor unit, appearance OK but operational condition unknown. He'd like to exchange it for hoary old software (preferably) or $5 + shipping costs. Contact him by email at: robklar(a)swri.edu. Thanks, - Mark

Even Bigger problem with VMS

by M.Malik＠roehampton.ac.uk

Hi, I have an old Vax 4100a/VMS 6.2 machine and have tried what was suggested here: http://www.heydon.org/kevan/mlists/classiccmp/1997- 07/msg00447.html The problem I have is that the system disk is full (probably due to log files) and I am unable to boot up because of this. It does not work even with minium boot, I just want to be able to boot to the system disk and to delete/purge some files to get the system back up again. Can anyone help? Thanks in advance. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Mubasher Malik Snr Systems Engineer C&IT (M.I.S Team) Roehampton Institute London Tel: 00 44 (0)208 392 3122 Fax: 00 44 (0)208 392 3182 e-mail: M.Malik(a)roehampton.ac.uk ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

It can go either way. The information itself is likely to be property of the US Gov if it, and the hardware to which it pertains, was developed under U.S. contract. Nonetheless, unless the manual was actually printed by the GOV it may be copyrighted by the developer of the manual. You have to look at the copyright declaration in the document. With hardware documentation which was freely and customarily given away, e.g. separately from the hardware itself, like the OEM manual for a floppy drive, it's unlikely the copyright can be claimed to be of any substantial value. The owner of the copyright can probably cause you to stop publishing, posting, and distributing it, but since it was never sold, violating the owner's copyright cannot be interpreted as substantial damage to the owner, hence no basis for judgment for damages exists. Another thing is that if you publish the information in a format different from that in which it was published, i.e. flowed around the embedded illustrations in a different way, though it damages the value by fouling up references to the figures, it makes your document not necessarily the one which was copyrighted to the owner. It just depends on how useful the resulting document is. I don't know how helpful it is to know these things, but it's always useful to remember that nothing's etched in concrete where courts, judges, and lawyers are involved. Everything's subject to interpretation. It's just hard to imagine a court awarding damages to the holder of a copyright on a document pertaining to, and only to, a specific piece of hardware, the owner of which is the one party to whom that information is of interest, since it was for his benefit that the information existed in the first place, and it was generated to support the sale of that hardware, which purpose was clearly fulfilled at some time in the past.

New finds and some h-11 help

by allisonp＠world.std.com

<> Will it boot into a monitor without the h-27 attached and is there a comm <> reference somewhere around? ODT, yes. Boot program no unless on the 9400YA. the LSI-11 cpu does not have boot program. I forget if the H27 Qbus card has a boot. Either way most PDP-11 boots are not that long to type in via ODT. <That depends entirely on your CPU/boot rom combo. My 11/23+ CPU (KDF11-AB <has an interactive boot program that lets me test stuff, dump the bus and <boot devices by name (DY0, DL1, etc.) The older ROMs for the 11/23+ aren' <as fancy - boot prompt (Y/N) and optionally the device mnemonic. No diags <no dialog. The 11/23+ was extended in that area, the 11/03, 11/2 and 11/23 (m8186) have no boots at all but, do have ODT. the 11/23 (m8189) series had three different rom sets with various boots that handled RX01/02, RL01/02, RK05 and Mop via serial plus other boot flavors and self tests.
