New find - Poor Man's Network - - for CP/M!

by r.stek＠snet.net

I just came across a piece of software I don't remember from 1987. It is called "Poor Man's Network: A Networking Package for CP/M Computers." It was put out by Anderson Techno-Products of Ottawa, Ontario. Judging from the manual, it appears to have been a one- or two-man operation (nothin' wrong with that - been there, done that). It uses standard serial or parallel ports and is based upon a very modified Christensen protocol to communicate with itself on the other computer (it only support two computers - after all, you couldn't afford more than two computers if you were really poor <g>). It's capabilities seem to have been to allow allow read and/or write access to files on the other computer (handy for those NorthStar hard-sector disk file transfers to and from 8" drives, for example), sharing drives on the other computer on a R/O basis, redirecting output to use the other computer's printer or plotter, sending one-line messages to the other computer, and the ability to send screen messages and data mesaages to the other computer and to receive data messages from the remote computer (simultaneous read and/or update a database using added BDOS calls). Sharing was on a drive basis only. It took up about 7-8k memory and worked with CP/M 2.2, ZRDOS or equivalent. Has anyone had any experience with this gem? Or even remember it? Were there others like it? By '87 I had become enmeshed in the IBM-Microsoft world, and don't remember this one at all! Bob Stek Saver of Lost Sols

Looking for Compute! Atari ST disks

by owad＠applefritter.com

I'm looking for the following Compute! disks for the Atari: Compute!'s Atari ST Disk December 1987 Volume 2 No. 6 Issue 8 Compute!'s Atari ST Disk February 1988 Volume 3 No. 1 Issue 9 All I'm really interested in is the contents, so I'd be quite happy with a copy. An .ST or .MSA file via email would be perfect. If anybody could help me out I'd appreciate it. Thanks, Tom Applefritter www.applefritter.com

I have LARGE amounts of disk space available, and decent bandwidth (2.3mbps, soon to be 5mbps hopefully)...I'd love to host this stuff. -Dave McGuire

TU-58 rollers and emulation (was Re: VAX 11/725)

by ajp166＠bellatlantic.net

From: Clint Wolff (VAX collector) <vaxman(a)qwest.net> >I've written one for DOS that needs some tweaking still... I'll cut >loose the source code if someone wants to fix it up. Basically, it >sometimes gets out of sync and you have to power down the 750 and >restart the PC to get it back working... You need to acknowledge that INIT from the host (750 or pdp11) can force the tu-58 back to initial status. on the real tu58 thats a break char and the resulting Framing Error from the Uart causes a TRAP interrupt (higest priority nonmaskable interrupt) on the 8085. A PC would have to sense a Framing Error (Character with no stop bit for at lest two character times) and force the code back to the starting point where RSP is restarted. I have prints and manuals plus some of the designers notes from by days as a Digit. Back when they were easy to find and a cheap way to put 512k of block oriented storage on a serial port of PDP-11 systems. I also have a few that used a parallel IO (used only for PDT11/130) that are otherwise identical. >THANKS Allison! I bought two from Keyways, Inc. for $40 + shipping... >For that price, I could have bought 20' of Tygon tubing... Live and >learn... For 40$ that should have been 80ft of tygon and at roughly .300 inches of it per roller that would be enough for a couple of Sagans of them. <one Sagan = billions and billions) I had it handy and it works *ok*. It's weakness is that it dents if the cart is left in place for long periods. It recovers if shape if the cart is removed but a more resilient material might be better. I used tygon as I had it at hand. A rubber hose material with the right dimensions would be a good choice. Also the dimater for the TU58 roller is non critical save for it works best if round. ;) The actual tape speed is controlled by the cpu and a PLL circuit and has a +-10% or more tolerence of roller diameter before there may be a tape speed problem at the ends of the tape.

Atari Portfolio

by jhellige＠earthlink.net

As of today, I'm the happy owner of an Atari Portfolio. Pretty neat little machine, with even a longer battery life than my Tandy 102. Due to it's small size, not as nice a keyboard though. Does anyone know where I can get additional 64k or 128k memory cards for it? It came with the parallel interface. Also, I've been told that the Portfolio is what was used by John Conner in 'Terminator 2' when he broke into the ATM and the Cyberdine vault...is this true? Jeff

Not to mention the fact that *really* early devices (multibus ethernet adapters come to mind, along with DEQNA's, and other stuff) that are AUI *only*. I've waited a *long* time for prices on AUI<->10bT tranceivers to fall to reasonable levels so I could easily hook up such beasts.

BSD/OS 1.1

by jhellige＠earthlink.net

We seem to have a bunch of Unix-types on here so I thought I'd pose a question. Today, I came across the following 5 HD disks from Berkeley Software Design Inc: - BSD/OS 1.1 Boot Disk 1, /boot and /bsd - BSD/OS 1.1 Boot Disk 2, Installation Utilities - BSD/OS 1.1 Kerberos, Kerberos Utilities - BSD/OS 1.1 Encryption, Encryption Utilities & Src - BSD/OS 1.1 EZ-Config, Configuration Tools What's missing from this set that would keep it from installing? Is there anything particularly interesting about it other than it appears to be the ancestor of the current Net/FreeBSD? Jeff

It's gotta have the cables though cause I can't seem to find them anywhere and they're useless without them. Also, I would be willing to help with pick-up if need be as I am only 1 hr away from philly. Just let me know. -Linc Fessenden

VaxServer 3100 and VT340 terminal

by ajp166＠bellatlantic.net

From: Compusync <hsappleton(a)sprintmail.com> >I humbly appreciate the response. For a novice(in a very conservative sense >of the word) user like myself, it will ultimately draw a couple other >have no experience in VAX/DEC or UNIX for that matter. I want to take care Is VMS install or Ultrix (possible NETBSD?)?? >1)can you help me identify the console port and/or second >serial port Look at back pannel, the symbols in the plastic should help. If it's a vaxserver there will be three 6pin connectors like a telephone plug only with an offset loging clip. While the connector is odd those ports are RS423 (very similar to RS232). The VT340 has matching connectors (2) and also the standard 25pin serial connector. The 25pin connector on the vaxserver is also RS232 but not console. It is a full handshaking serial port suitable for a modem. >2)Don't I need some kind of cable and what type For the serial its just called MMJ or deconnect. There is only one type and varies only in length (no null modem or other odd wired versions). >3)what is MMJ ports and port 0 also has an RS232 output VT340 terminal on the back. >My VaxServer is has the following ports: SCSI, Standard SCSI-II useable with many types of drives, tapes and some CDroms. >a 25-pin db Modem use usually works up to 19.2k maybe 38kb. > 3 rj-11 type Those are acutally MMJ (modified modular jack/plug).

Used with the right cable/connector it's 8 more serial ports. >My VT340 has the following ports: 2 RJ-11 type with left and right arrows; a >printer port; a keyboard port; a 25-pin dB port; and a 8-pin mini din port Ignore the 8pin mini-DIN as thats for optional mouse. The two RJ11 as you call them are the MMJ serial ports and port 0 is shared with the DB25. Which port is in use is selected by F4 (session select) and also the on screen configuration. NOTE: VT340 is a very nice DUAL session terminal. It allows two connection running at the same time independently or two sessions over one wire (under VMS or terminal server). I only have three VAXserver3100s (M10E versions) in the VAX herd (9 in all). I also have an assortment of terminals including a few VT320s, VT340, VT1200, VT125 and H19 (I built as a kit in 1978).
