Was anyone else at Trenton this weekend?

by evan＠snarc.net

Just wondering who else might've fought the rain at the Trenton Computer Festival this weekend. >From our regional club, there was: John Allain, Bob Applegate, Bill Degnan, Bob Grieb, Herb Johnson, Andy Meyer, Bryan Pope, Jim Scheef, and myself. A few random people visited our club booth and said they used to be here on classiccmp, but I didn't get names. Best score of the flea market: Bill Degnan obtained a PDP-11.

New GTTY - A Glass TTY + Load paper tape for a PDP-8/E/F/M/A - now WITH "PACING"

by lbickley＠bickleywest.com

Want a program to act as a "Glass" TTY for your PDP-8x - with paper tape file upload and capture capabilities? Free? You can download if via anonymous FTP >from "bickleywest.com" or using your browser via "ftp://bickleywest.com". The new version of "GTTY" contains pacing, so that slow PDP-8 programs can read from the "paper tape reader" without issues. Included: The hardware changes you'll need to make on your console async. board to get "pacing" functionality. To make it work you'll need a serial cable from your PDP-8/x TTY console (EIA RS-232 mode) to the serial port of a DOS capable PC. GTTY has been tested with DOS 6.22 and a DOS Window in Windows 98se and Windows XT. A copy of the file "gtty.txt" which describes it's capabilities and limitations is below. ---------------------------------------------------------- GTTY - A Glass TTY + Load paper tape software into a PDP-8 Version 0.91, 4/24/2006 ---------------------------------------------------------- Lyle Bickley, Bickley Consulting West Inc. Note: Changes from release 0.8 include: 1) Ability to "pace" using hardware CTS based on Reader Run. Helpful in dealing with slow software reads from "paper tape" by FOCAL, etc. 2) New function to allow escaping from a "hung" load from CTS drop (Reader Run off). Useful when the BIN loader halts on completion of a load - and there is still "paper tape" trailer in a file. 3) Now supports up to 38400 baud. 4) There is a new function key and a new parameter (see below) Acknowledgemets --------------- This software was inspired by K. McQuiggin's "RIM Client, Version 0.2" (July, 1998), AKA "send.c": http://highgate.comm.sfu.ca/pdp8/software/send.c The hardware modifications recommended below are directly or indirectly >from Aaron Nabil's site: http://pdp-8.org/flow.html. Also helpful are Douglas Jones "Notes" on the KL8E and KL8JA asynchronous Interfaces: http://www.cs.uiowa.edu/~jones/pdp8/hard8e/kl8e.html http://www.cs.uiowa.edu/~jones/pdp8/hard8e/kl8ja.html Software - "Glass TTY - GTTY" ----------------------------- I decided to write a complete "Glass" TTY that could be used as a console, paper tape "reader" and "punch" for my PDP-8/F. I also wanted it to be capable of "pacing", so it could be functional with programs such as FOCAL and multi-segement tapes. Starting up, it is a full duplex glass TTY - and sends the characters you type to the PDP-8 and displays the characters received from the PDP-8 on the screen/monitor. Hitting the "F2" key - it asks you for a PT (paper tape) filename - lets you specify whether you want it to strip "garbage" characters from the tape before uploading it to the PDP8. After the upload, it automatically switches back to "glass" TTY mode. If GTTY get's "hung" while uploading (typically the BIN loader halting after complition of a load with trailer remaining in the "reader") hit F3. This will escape the pacing wait from CTS dropping (RDR RUN off). Hitting the "F4" key asks for the name of a "Capture" file. After entering a filename and hitting "Enter", all data received from the PDP-8 will be captured to the file. Note that the display is turned off - as typically the data to be "captured" is a binary punch file. Hitting the "F5" key closes the capture file and GTTY switches back to "glass" TTY mode. The other two active function keys are "F1" - Help, and "F6" - Exit. Notes: 1. No function keys get passed to the PDP-8 (even those that are not "progamatically active". 2. Filenames are limited to DOS's 8.3 filename format. 3. The GTTY startup parameters (upper or lower case) are: -P port [COM port=1,2,3 or 4] Default "1" -B baud [Baud rate=110,300,600,1200,2400,4800,9600 or 19200] Default "9600" -S stop bits [Number of stop bits=1 or 2] Default "1" -N No CTS hardware (Turns of pacing for those who haven't made the appropriate hardware changes to their KL8E or KL8-JA boards.) -H help 4. I'm a *NIX buff and haven't written DOS code for years, but I wrote GTTY as a DOS program because I know there are a lot of collectors that use "imagedisk", "Teledisk", "PUTR", etc. which only operate on DOS - and many folks who don't have *NIX systems. I've successfully tested GTTY on DOS 6.22, Windows 98 SE in a DOS window, and Windows XT [Home Edition] in a DOS window. 5. I'm including the source code, for anyone who would like to "hack" the program, add feature, etc. My only request is that if you release it back to the community that you change it's name, and maintain my copyright notice in the code and startup. Note that it is totally "free" when used for non-commercial use. Please contact me at lbickley at bickleywest.com for commercial use. 6. I wrote GTTY in "C" - and wanted to use a freely available DOS compiler and libraries. I selected Dave Dunfield's "Micro-C". Dave's compiler and libraries let you get close enough to the "metal" to make a program such as GTTY responsive and effective - easily handling communications, screen and keyboard control simultaneously. His compiler can be downloaded from: www.dunfield.com, either "free" or if you want all the examples and library source (I did) for the modest cost of $25. 7. I've successfully uploaded virtually every paper tape diagnostic available for my system (and it's I/O). In addition, I've uploaded FOCAL and other software without error at 9600 baud. I've tried it using both the M8550-YA and the M8655 "TTY" console boards with equal success. 8. I've tested GTTY with 38400 baud and slow reading - and pacing works! 9. The keyboard backspace and delete keys both generate a TTY rubout (Octal 377) character. NEW Section - Hardware changes to implement "Pacing" ---------------------------------------------------- When running programs like the RIM or BIN loaders, the PDP-8/E is easily able to "keep up" reading a paper tape file from GTTY. However, some programs as FOCAL, read the paper tape reader slowly. Without hardware modifications, GTTY will attempt to "cram" characters to the PDP-8 when it isn't capable of reading them - hence missed data. To fix this problem, your M8550 or M8655 TTY console board needs to be modified. The modification essentially ties RTS/DTR (CTS after a full handshake null modem) to the Reader Run flip flop on the console board. GTTY is able to sense CTS and wait until Reader Run is set (CTS O.K.) before sending a character to the PDP-8. The hardware changes for the KL8-JA are written up nicely by Aaron Nabil at his website: http://pdp-8.org/flow.html. I suggest that you use the "UNTESTED BUT SHOULD WORK" procedure described after steps 1-5. I've tested it - and it works perfectly. The big advantage of this procedure is that current loop remains functional. I also wanted GTTY to work with the older KL8E async controller (M8650). It turns out that the hardware modifications are much easier on the older board! On E32 (MC1488) remove the solder from pins 4 and 5. Gently bend the pins away >from the board so they no longer make contact. Solder both pins 4 and 5 to a jumper wire. Connect the other end of the jumper to E48 (7474 - Rdr Run) pin 9. That's it! The older board works great with both current and EIA modes without any other changes. Have fun! Cheers, Lyle -- Lyle Bickley Bickley Consulting West Inc.

Cosmetic replicas

by ggs＠shiresoft.com

Hi, I wanted to let you folks know that I'm getting pricing on having some cosmetic parts made up. Here's what I'm going for: * 11/20 front panel plexis. These will be the original colors and be an exact replica of the original 11/20 front panel plexi. It be identical in every way to the original (except that it will look *new*). * H960 header panel inserts. Right now I'm getting quotes for the blank magenta/red and the D|I|G|I|T|A|L PDP-11 inserts. However, I also expect to be able to have produced the yellow/brown and PDP-8E inserts as well. Note that these are *not* the plasic header panels but are the inserts that go in them. As soon as I have pricing I'll let y'all know. It should be in a couple of days. -- TTFN - Guy

1350A vs 1351A

by bobalan＠sbcglobal.net

<>No, I'm not sure. It's been a long time. However that's the resolutions given in the manual for the 1350 and in the HP 1980 and 1982 catalogs. Probably they are just rounding it off. The manual does mention the X=1022, Y=1023 max values for a plot absolute command.

VAX ADVENTURE, was Re: RL02 problem

by henk.gooijen＠oce.com

Ohh boy, if I can not use the HSC70, even if the CI board L0009 is installed in the VAX without the CI750 (which is a complete cabinets in its own), I think I will try to sell the HSC70 to get some money back spent on the transportation on the system ... I really don't have the space for yet an other cabinet :-( I downloaded DUNGEON, but I mean Zork. Are those two (almost) identical? I never saw Zork, just read about it in an article. I will check out DUNGEON and ADVENT in RT-11 is a couple of weeks. I will also take the time to read through the updated manual (I know, ...

anyone have a terminal server?

by dm561＠torfree.net

How about a single port terminal server or a PC running TS software connected to one of the ports of an RS232 PBX; that should give pretty well any connection option. Local computers, terminals & printers could talk to each other and also have access to the net. mike ----------------Original Message: Date: Mon, 24 Apr 2006 22:46:31 -0500 From: "Jay West" <jwest at classiccmp.org> Subject: Re: anyone have a terminal server?
