RC2014 ESP32Z80 V2 Emulator for TTGO VGA32

• Not Boot without a SDCard

• Booting with SDCard
  

• Showing the DiskSpace of the A: (A.dsk) Image-File

• Executing Wordstar 4.0

The Jr-cutDown-Version lacks the following Features of the original Emulator-Version:

• virtual GPIO-Support is missing
• Telnet-Support is missing
• SPIFFS-Support is missing
• Code-Fragments of TTGO T1/T2 are not included BUT SDCard-Support-Commands like sdfiles and sdcopy does work ;)

The original version of the ESP32-Z80-Emulator (without VGA32-Support)
from David Bottrill (david@bottrill.org) is available at
https://github.com/djbottrill/ESP32-Z80-Emulator

This VGA32-Port does use the FabGL-VGATextController with 16 Colors

• Notes / Problems at this time:
  • Breakpoint GPIO-Switches sw1(26) & sw2 (27) may be incorect or non free GPIOs
  • Config of Keyboard and Screen-Color via .ino because I had to use FabGL TextController instead the VGA16-Controller (got Problems to get the SDCard to init)
  • Does hang/freeze when exiting Wordstar 3.30 / 4.00 with the X-command
  • Does throw exception when starting Turbo Pascal v3.01A (after Error-Msg Question)
