I found files for my favorite DOS editor on an archive from my OS/2 machine, which replaced my DOS machine in about 1990. The editor was ETOOL, from Amerisoft. If anybody wants the files, I'm happy to send them. -rw-r--r-- 1 vsnyder staff 245248 Mar 8 1988 e/dos/etool.exe -rw-r--r-- 1 vsnyder staff 1024 Mar 8 1988 e/dos/etool.fig -rw-r--r-- 1 vsnyder staff 83968 Jul 9 1985 e/dos/etool.hlp I lost the manual decades ago.

PDP-11 Unix V7M-11 V1.0 under SIMH

by tony.nicholson＠computer.org

Recently Al Kossow made available a zip file containing a Micro/PDP-11 installation kit for Unix V7M-11 V1.0 on bitsavers as RX50 disk images. Tinkering away here in Covid lockdown, I've managed to get this running under SIMH pdp11 emulating an almost historically accurate PDP-11/23 plus. I've placed the SIMH initialisation file, a couple of RD51 disk images and an "installation recipe" for making these disks on GitHub at - https://github.com/agn453/V7M-11 While I mainly had exposure to later versions of Unix and Ultrix-11 on a PDP-11/70 as an undergraduate - this one surely brings back memories!

Terminal Emulator

by mmcgraw74＠gmail.com

I use both Realterm and Tera Term. Realterm does not emulate terminals - but is able to display ALL the ASCII characters including the Control Characters and even 8-bit characters. This has been invaluable to me working with my late 1970's Tektronix 4052 and 4054A computers, which made heavy use of ten of the ASCII control characters for quick formatting of BASIC PRINT commands without requiring multiple PRINT commands. Realterm also can capture the entire stream of ASCII characters to a file - which is invaluable in capturing all the characters from DC300 Tektronix program tape cartridges. I use the XON/XOFF feature with both my 4052 and 4054A to send and receive ASCII programs to the Tektronix computers at 9600 baud. Here is an example output of Realterm with printed control characters - as I am debugging my Arduino program to emulate the Tektronix 4924 GPIB tape drive: https://www.eevblog.com/forum/projects/tektronix-4924-tape-drive-emulator/m… I also use Tera Term - as it is able to emulate Tektronix graphics terminals, both the 4012/4014 vector graphics AND the 'newer' 4100 series color graphics terminals! My Tektronix 4041 GPIB controller computers (68000 based) had only a single line LED display, but supported Tektronix 4012/4014 if you had the optional Graphics ROM. I was able to port several of my 4050 graphics games to 4041 BASIC (Artillery, Lunar Lander, and my port of Adventure) using Tera Term on my Windows 10 PC as the terminal to display the graphics/text and for data input. I also recovered the 4041 EZ-TEST (GPIB interactive program development) tapes, which only supported the 4100 color terminals - and used Tera Term successfully to emulate those color terminals. Tera Term also supports XON/XOFF and file capture/restore, so I have been able to use it with my 4041 computer to replace the internal DC100 tape drive and load and restore programs from my Windows 10 PC. See example Tera Term vector graphics screenshots and color terminal screenshots in my 4041 thread on vcfed.org: https://www.vcfed.org/forum/forum/genres/other/76507-tektronix-4041-compute… Monty > Date: Fri, 1 Oct 2021 19:57:19 -0700 > From: Curious Marc <curiousmarc3 at gmail.com> > To: lee_courtney at acm.org, Lee Courtney <leec2124 at gmail.com>, "General > Discussion: On-Topic and Off-Topic Posts" <cctalk at classiccmp.org> > Subject: Re: Terminal Emulator > Message-ID: <50E6AD1D-F0D5-42CB-93A8-163B9945BB48 at gmail.com> > Content-Type: text/plain; charset=utf-8 > > I use Teraterm too.

MD5 list of bitsavers files

by a.carlini＠ntlworld.com

I'm trying to list out the document scans I have and work out which are already on bitsavers and which are not (and, indeed, a fair few of these are originally from bitsavers anyway). This is probably several thousand files total, so searching manx by hand is not an option! I see that manx lists the MD5 checksum for many files, at least it does for those from bitsavers. Is there a publicly available list of URL and MD5 checksum? This would make it relatively easy for me to cross check my files against the list and whittle down to a subset that I should make available. Alternatively, is the current manx database available anywhere? I know the code is on github, but I didn't see the data there. (I do have an SQL dump from 2010 when manx changed hands, but that's not recent enough to save much). I could try to do some parsing of bitsavers-filename => DEC-part-number and eliminate files that way, but that seems inexact at best. Or I could just download the DEC subset of files (spread across the mirrors) but that seems a bit antisocial. Antonio -- Antonio Carlini antonio at acarlini.com

Has anyone gotten the old SIMH VAX-11/730 emulator to boot?

by ethan.dicks＠gmail.com

Hi, All, I'm fiddling with my 11/725 and as part of that, I'm prepping possible system images to deploy using the 10-year-old 11/730 emulator that's now part of SIMH. I'm trying to get the original (v3.8) version working because of the numerous changes to how simh 4.0 works now. I'm working from the sources on http://www.9track.net/simh/vax730/ They compiled just fine and the binary runs (on Linux, FWIW) but I've tried booting several different TU58 images and VMS device images and so far, they all tell me "file open error". Here's the current config with me trying to run the CRD tape/disk combo (trimmed just show mounted images on TD0 and RB1). sim> show conf VAX730 simulator configuration CPU, idle disabled, 2048KB, HALT to SIMH . . . TD, 2 units TD0, 262KB, attached to BE-T176I-DE.tu58, write enabled TD1, 262KB, not attached, write enabled . . . RB, address=FFFB86-FFFB87, vector=2A8, 4 units RB0, 64MW, not attached, write enabled, RB80 RB1, 5242KW, attached to CRDPACK-RL02.img, write enabled, RB02 RB2, 5242KW, not attached, write enabled, RB02 RB3, 5242KW, not attached, write enabled, RB02 If I have to, I can grab the source for the current version off of github, but having looked it over, it's essentially this same emulator (with commit dates of 9-10 years ago) plus some recent structural cleanup that's similar across all emulators. The functional parts are this same emulator. Thanks for any tips. -ethan

SCSI2SD in a DEC 3000/300 - T-ERR-SCSI A

by jjacocks＠mac.com

I?ve got a DEC 3000/300 system that has some SCSI drives with aging bearings installed. I?d like to be able to start to migrate some of my systems, like this, to flash media, of some kind, as even my large repository of SCSI disks is starting to dry up. Here is my SRM level info: DEC 3000 - M300 Digital Equipment Corporation VPP PAL V5.56-80800101/OSF PAL V1.45-80800201 - Built on 30-SEP-1996 09:18:31.84 As far as I have read, the SCSI2SD v6 2020 should be compatible with several varieties of DEC hardware, from the VAXen to the Alphas. However, I can?t seem to get anywhere useful with mine. I have the virtual disks configured as follows: >>> sh dev BOOTDEV ADDR DEVTYPE NUMBYTES RM/FX WP DEVNAM REV ------- ---- ------- -------- ----- -- ------ --- ESA0 08-00-2B-3F-4C-9A , TENBT DKA100 A/1/0 DISK 9.54GB FX RZ40 6.0 DKA300 A/3/0 DISK 9.54GB FX RZ40 6.0 DKA400 A/4/0 RODISK 305.01MB RM WP RRD45 6.0 All three disks are from the SCSI2SD. I have attempted to make the inquiry strings match the originals, as closely as possible. In the SCSI2SD utility, I have the following config: General page: all defaults, termination off (I have tried parity, scsi2 mode, and setting SCSI speed to sync, with no improvement) Device 1: enabled, ID 1, device Hard Drive, start sector 0, sector size 512, sector count 18636800, vendor ?DEC ", product ?RZ40 ?, revision ? 6.0?, serial number <random string> Device 2: enabled, ID 3, device Hard Drive, start sector 18636800, sector size 512, sector count 18636800, vendor ?DEC ", product ?RZ40 ?, revision ? 6.0?, serial number <random string + 1> Device 3: enabled, ID 4, device CDROM, start sector 37273600, sector size 2048, sector count 148933, vendor ?DEC ", product ?RRD45 ?, revision ? 6.0?, serial number <random string + 2> I?ve also tried booting from a virtual CDROM, only, with no luck there, either. In all cases, I get the following from SRM: >>> test scsi T-STS-SCSI A - Data Trans test ? T-ERR-SCSI A - Data Trans test - nondma/sync inq size miscompare T-ERR-SCSI A - id = 1 lun = 0 ? T-ERR-SCSI A - Data Trans test - nondma/sync inq size miscompare T-ERR-SCSI A - id = 3 lun = 0 ? T-ERR-SCSI A - Data Trans test - nondma/sync inq size miscompare T-ERR-SCSI A - id = 4 lun = 0 ?? 002 SCSI 0x0008 84 FAIL Does anyone have an idea what might be causing this? Has anyone tried a v6 SCSI2SD in a DEC 3000? Thanks! - Alex

ISO M100, M102, M633 flip chips for DEC TC08N controller

by derschjo＠gmail.com

Hey all -- I have a TC08 DECtape controller that I'd like to convert to a TC08N (the negibus version of the TC08). If I'm reading the documentation right, this involves swapping in a few flip chips -- M100 for the installed M101, M102 for M103, and M633 for M623. If anyone has any of these, please drop me a line. Curious also if anyone out there has done this conversion and can comment on whether my assessment is correct... Thanks! - Josh

I used ZOC, and loved it, when I was an OS/2 user decades ago. I?m glad to hear it?s still around. Adam

Anyone out there with a working Victor 9000 (US only)?

by cclist＠sydex.com

Got a small batch (8) of Victor 9000 floppies, MSDOS ca. 1985. I really don't want to write a decoder for such a small batch--I've got other things on the burner right now. Anyone want to take a crack at transferring the data? (Funds available). --Chuck
