 Posted: Fri Oct 03, 2014 2:23 am Post subject: Tektronix 4010(4014) graphic terminal (emulator) library |
 |
|
Tektronix 4010 (4014) is a computer graphics terminal of an old time.
Catalog: Tektronix 4010 Computer Display Terminal
Terminal emulator software "Tera Term" has a TEK4010 (4014) terminal emulation function.
BASCOM makes a graph draw to a personal computer using this function.
It connects by "RS-232C" or "USB-serial conversion" using UART of AVR.
Since the Arduino board carries "USB-serial conversion", the addition of an option is unnecessary.
AVR obtains the display screen of high resolution, and acquires the capability to print(Hard copy) it with a printer!
Computer screen  Hard copy 
1.Download and install the latest version of "Tera Term" from "SourceForge.jp".
2.[Setup] -> [Serial port] -> "Serial port setup" dialog box．Set the baud rate.
3.[Setup] -> [Terminal] -> "Terminal setup" dialog box. Enable the "Auto switch (VT<->TEK)".
4.[Control] -> [Open TEK] -> Opens the TEK window.
[Setup] -> [Font] -> "Font" dialog box. Font size is changed into any value. (Example: Size 16)
5.[Setup] -> [Window] -> "Window setup" dialog box. The color of "Text" and "Background" is changeable.
6.[VT-window] -> Return to the "VT-window".
[Setup] -> [Save setup] -> "Save setup" dialog box. Save the settings.

Hello O-Family,
great nostalgic application 
It was nice to read the brochure. $3500 for a terminal, wow !
Your lib is a good example for a serial based display.
Because of the emulator it is simple to try.
Thanks for sharing.

The above was corresponds to 4010 (4014) of monochrome display.
"Tera Term" also corresponds to 410x of color display.
Therefore, I added the "Tekcolor" command for specifying the drawing color.
Computer screen 
1.Download and install the latest version of "Tera Term" from "SourceForge.jp".
2.[Setup] -> [Serial port] -> "Serial port setup" dialog box．Set the baud rate.
3.[Setup] -> [Terminal] -> "Terminal setup" dialog box. Enable the "Auto switch (VT<->TEK)".
4.[Control] -> [Open TEK] -> Opens the TEK window.
[Setup] -> [Font] -> "Font" dialog box. Font size is changed into any value. (Example: Size 16)
5.[Setup] -> [Window] -> "Window setup" dialog box. Enable the "Color emulation".
Background color, you can change by "Reverse" button.
6.[VT-window] -> Return to the "VT-window".
[Setup] -> [Save setup] -> "Save setup" dialog box. Save the settings.

| Wow! That brought back memories. When I was quite a bit younger I bought a 4010 terminal surplus for about $20 or $30 USD. I think I had to fix up the power supply to get it to work. Anyway, these were fun to watch since they work kind of like an oscilloscope with persistence. I remember writing a 4010 driver for a program I wrote. I was able to output 2D graphs and such. Anyway, thanks for sharing this. |

This post reminded me that I have one of these old but faschinating A0-plotters from HP (the 7580 model) standing in a corner of the lab.
I remember that the price tag was USD15000 at the time (1985) so it still stand there. It is working but of no use.
Some day I will Power it up again and use it for something I yet have not figured out...
I wonder if some bascom-guy have written a driver for it? It is designed for HPGL so most commands are "standard" HPGL graphic commands.
Wathing this machine in full action is a true pleasure.

Thank you O-Family for this lib. I was searching the web for a Tek4010 emulator and was surprised to end up here on the MCS forum. I didn't know that my favorite terminal program (tera term) had tek4010 emulation built in. I used one of these terminals way back in 1978 and 79 so for nostalgia I want to use this to display something. I've spent the last few days writing a rudimentary chart program that uses you lib. I've included a zip file with my demo and two Tek4010 user manuals. The demo shows how to get different fonts and how Gin mode can be used to display a cross-hair for user input.
I had to change one line of code in your lib file to get it to compile for AVRX processors:
At line 26 of the lib file:
'Comment out ---> ;*BASIC: Printbin _temptx 'Send to USART. *** REMOVED, WILL NOT COMPILE WITH MY COM CONFIG.
'Replace with --> *BASIC: Print #1, chr(_temptx); 'Send to USART. *** SAME THING USING PRINT.
I'm running at 38400 baud but with a few tricks it will plot at the fastest baud tera term will run at (921600 baud). If anyone is interested in plotting faster I'll share how I did that.
Also there is a beautiful Tek4010 emulator for Raspberry Pi. I had a Pi Zero laying around so I tried it and it works fine. That emulator simulates the 4010 in a much more realistic way.
Thanks again
Dave |
