0.34b4 [Nicola Salmoria]

0.28 [Christopher Kirmse, Aaron Giles, Nicola Salmoria]


Artwork available


WIP:

- 0.153: Osso removed hardcoded DIAL increment/decrement for Discs of Tron.

- 0.145u7: Moved Sound Board prom 82s123.12d to midssio device set. Added 'Midway SSIO Sound Board' and 'Midway Squawk 'n' Talk Sound Board' sound to clone Discs of Tron (Environmental).

- 23rd October 2009: Mr. Do - Jcroach found another missing piece to the Discs of Tron puzzle, which gives the game that much more "oomph".

- 0.122u7: Changed M6802 CPU3 clock speed to 3579545 Hz in clone (Environmental).

- 0.122u6: Changed M6802 CPU3 clock speed to 894886 Hz and replaced TMS5220 with TMS5200 in clone (Environmental).

- 0.117u2: Aaron Giles fixed input in clone (Environmental).

- 29th April 2007: Mr. Do - Discs of Tron now has outer artwork, thanks to BYOAC (for the inner) and to Mark B. from Surfside Music and Collectibles (for the outer). Credit for vectoring both pieces to Jcroach.

- 0.109u2: Added prom ($20 - lamp sequencer) to clone Discs of Tron (Environmental).

- 0.106u10: Aaron Giles updated Discs of Tron to support the new artwork system.

- 0.100u3: Removed audio CPU roms in (Upright) and clone (Upright alternate). Only clone Discs of Tron (Environmental) used M6802/TMS5220 audio roms.

- 0.98u4: Removed M6802 CPU3 and TMS5220 speech in Discs of Tron (Upright) and clone (Upright alternate).

- 0.98u1: Fixed cpu3 roms addresses. Removed 3rd sound channel.

- 0.93: Added 3rd sound channel.

- 0.63: Added clone Discs of Tron (Upright alternate).

- 0.61: Changed visible area to 512x480 and palettesize from 32832 to 64 colors.

- 0.56: Removed 3rd coin slot.

- 18th August 2001: Nicola Salmoria adjusted the Discs of Tron driver for new artwork.

- 0.54: Fixed messed up backdrop in Discs of Tron. Changed visible area to 684x642.

- 0.53: Changed visible area to 640x600.

- 16th April 2001: Mathis Rosenhauer fixed another artwork system problem, and fixed Discs of Tron from crashing.

- 26th July 2000: Mark Jenison dumped Discs of Tron (Upright alternate).

- 0.37b3: Changed palettesize from 254 to 32832 colors.

- 28th November 1999: Zsolt Vasvari fixed dotron in 16bpp.

- 16th November 1999: Mathis Rosenhauer fixed Discs of Tron backdrop.

- 0.36b8: Nicola Salmoria change the mouse buttons to no longer aliases for joystick buttons, they are independently recognized. They are still considered "joystick" inputs though, so if you want to use them you have to redefine the controls in the Joystick menu. This is a minor annoyance that was needed to allow interfacing a Discs of Tron controller to the mouse port (spinner + up and down switches) while still using joystick buttons 1 and 2 for fire and deflect.

- 0.35b12: Changed M6802 CPU3 clock speed to 895000 Hz.

- 0.35b10: Changed M6802 CPU3 clock speed to 3580000 Hz.

- 0.34b8: Background light support in Discs of Tron [Mathis Rosenhauer].

- 0.34b4: Nicola Salmoria added Discs of Tron (Upright). Jim Thevenot fixed hang on level 7 of Discs of Tron. Preliminary backdrop support in Discs of Tron. The background image must be called ARTWORK/DOTRON.PNG [Mathis Rosenhauer, Brandon Kirkpatrick]. Changed 'Discs of Tron' to clone 'Discs of Tron (Environmental)'. Renamed (dotron) to (dotrone).

- 0.33b4: Nicola Salmoria fixed -ror and -rol with ORIENTATION_FLIP_X games (e.g. Discs of Tron).

- 0.30: Frank Palazzolo added TI TMS5220 speech emulator to MAME and Aaron Giles added the TMS5220 speech to Discs of Tron.

- 0.29: Known issues: The game stops when you reach the level where you can aim up and down.

- 0.28: Added 'Discs of Tron' (Bally Midway 1983). Speech is not emulated and the game stops when you reach the level where you can aim up and down. Christopher Kirmse, Aaron Giles and Brad Oliver provided a MCR I/II/III driver, supporting: Kick, Solar Fox, Tron, Two Tigers, Domino Man, Satan's Hollow, Wacko, Kozmik Kroozr, Journey, Tapper, Discs of Tron, Demolition Derby, Timber, Spy Hunter and Rampage. Control: Press F2 before initial screen to configure. Arrows = Move around, CTRL = Fire, Track = Aim, ALT = Deflect and A/Z = Vertical Aim. At this time, the game requires a trackball (-trak option). Known issues: Speech is not emulated.

- 15th March 1997: Malcor dumped Discs of Tron (Environmental).

- TRIVIA -

Discs of Tron was released in March 1983.

Also released as "Discs of Tron [Environmental model]".

Discs of Tron was originally designed to be a part of the original "Tron" coin-op, but was cut out at the end and set aside for refinement and release as a stand-alone coin-op in its own right.

Discs of Tron is inspired by the short sequence in the movie (Tron, 1982 Disney) where the character Flynn beats another trapped program and eventually 'derezzes' him, and when Tron is introduced, beating four 'computer players' very early in the movie.

David Bagenski holds the official record for this game with 418,200 points on June 28, 1986.

A Discs of Tron 'prototype' machine was shown at the 2003 classic arcade games show 'California Extreme' in San Jose, California.
