Plotting Spock on the Tektronix 4014

[GrantMeStrength]

I saw the picture of Spock plotted on the new TEK: device and thought "that's something I want to do".

The spock.plt file can be downloaded as part of this repo: https://github.com/rricharz/make-tek-image

It works with the plot.com command that is included on the disk added to the library when you flash the firmware.

One problem: how do you get the spock.plt file onto your IMSAI? Here's how I did it, and I welcome an easier way:

1. Install the cpmtools suite (details: http://www.moria.de/~michael/cpmtools/) on a Mac I used brew install cpmtools
2. Download a floppy disk image from the Library (drag an unmounted disk to the little download arrow)
3. Duplicate the disk image, use cpmrm to remove files and copy the spock.plt file to it.
4. Realize the spock.plt is TOO LARGE to fit onto a floppy so instead, use the 4Mb Hard Drive image file (you are using that, mounted as I: right? It's really convenient.)
5. Edit the boot.config from SYS to comment out the hard drive image (if you are using it) and then restart the IMSAI to unmount it, and then download the image (drag it from the Library to the little download arrow).
6. Add the spock.plt file using cpmcp -f4mb-hd <location of the disk image .hdd> <location of the spock.plt file> 0:spock.plt
7. Check it's been added with cpmls <location of the disk image>
8. Drag the HDD file back into the IMSAI Library, edit boot.config to mount the hard drive image, reboot the IMSAI.
9. Now the file is on I: and you can use plot.com to draw it. Have a cup of tea as it renders. Maybe two!

I used Xmodem (XM) via Teraterm (Win10) straight on to the hard disk. You can also create your own images. - see the 'show and tell' on the menu bar. If you are on linux then ...................................................!!!!!!!!!!!!

You have a serial link between the IMSAI and your computer? Or does this work over Wifi?

[villaromba]

I use the USB connection from Imsai to PC (not via the GUI) . This then shows up on Teraterm . This is as per the Manual : Serial UART over USB. The ESP32-PICO-KIT supports serial communications from UART0 over USB. It uses a Silicon Labs CP210x USB to UART bridge
1/ connect the ESPP32-PICO-KIT to a PC using a suitable USB cable
2/ start a terminal emulator on the PC set for 115200 baud 8N1 connected to the serial device your OS identifies the ESP32-PICO-KIT on
Windows will be a COMx: port

I have my port set to 9600 baud as XM seems more reliable (in my case) at a lower speed.

RE: Step 6.

There is also a format in cpmtools called z80pack-hd and this is the one @udo-munk recommends on his site for Z80PACK
The two defs. are different so I'd use z80pack-hd just to be sure.
