RE: Speed of HP-49G Routine for Tektronix Vector Graphics Terminal
... in the meantime I have written my notes for my Tektronix emulation with the HP-49G example program. I have not yet tested the last Assembler version - the previous versions crashed in my setup, which ist more likely my fault than yours, Werner.

While I will use the terminal emulator with larger computers, like a 64 KByte CP/M system, it ma also be of interest to some of you. Just a simple 10$ ESP32 board is able to generate the VGA signal and handle keyboard and mouse at the same time.
It is also a very simple means to present graphics from the HP 4x calculator on a larger screen or video projector.
My notes can be downloaded here: TTGO-VGA32.pdf
