Release 3

Added

• Simulation of an original PET2001

• Diagnostic dongles for the user port and keyboard to be used with the Diagnostic ROM/Clip.

• Simulation of the Commodore Diagnostic Clip (6502-DIAG-Clip.dig)

• User port connector

Changed

• There are now two mainboard files:

  • Mainboard-CBM3032.dig
  • Mainboard-PET2001-4.dig

  for the two simulated systems.

• Monitor.dig changed to

  • CRT-green.dig and
  • CRT-white.dig

• PETComponentsDigitalPlugin.jar upgraded to 1.0.1 (fixed errors in 6520 and 6522 simulations)

• README.md updated

Fixed

• 74LS165 circuit issue.

• Mainboard-CBM3032.dig: "Write Protect" ROM to prevent simulation crash when writing to ROM (e.g by CBM Diagnostic ROM)

Release 2

This release fixes the issue of randomly booting into TIM or BASIC. This can now be selected as required (default boot to BASIC)
Also a new PETComponentsDigitalPlugin.jar is included, which fixes errors in the 6522 Timer to make the cassette tape write work.

As a homage to the simulated system the CRT is changed from white-on-black (like the original PET) to the green-on-black of real PET2001N/CBM3000 CRTs.

Release 1

Simulation is working with some known minor bugs.
