Merit CRT250 and CRT260 hardware
Driver by Mariusz Wojcieszek
CRT 250 (basic components, also used by CRT260)
Main CPU: Z80B
Sound: Yamaha YM2149F (or compatible)
Video: 2 Yamaha V9938 (MSX2 video chip!)
Other: 2 Z80APIO (I/O and interrupt controllers)
1 8255 (I/O)
CRT 260 additional components:
- Microtouch touch screen controller (SMT-3)
- PC16550 UART (for communication with touch screen controller)
- DS1204 Electronic Key (for protection)
- DS1232 Reset and Watchdog
- MAX232 (for MegaLink)
One of the following Dallas Nonvolatile SRAM chips:

- DS1230Y 256K Non-volitile SRAM (Mega Touch 6)
- DS1644 32K NVRAM + RTC (Tournament sets)

Custom Program Versions (from Super Megatouch IV manual):
PROGRAM# Program Version Program Differences
---------------------------------------------------------------------------------------------
9255-41-01 Standard Version Includes all Options, no Restrictions
9255-41-02 Minnesota Version Excludes Casino Games
9255-41-06 California Version Excludes Poker Double-up feature & No Free Game in Solitaire
9255-41-07 New Jersey Version Includes 2-Coin Limit with Lockout Coil
9255-41-50 Bi-Lingual ENG/GER Same as Standard Version, Without Word/Casino Games
9255-41-57 Internation Version Same as Standard Version, Without Word Games
9255-41-60 Bi-Lingual ENG/FRE Same as Standard Version, Without Word/Casino Games
9255-41-62 No Free Credit Same as Standard Version, With No Free Credit
9255-41-70 Australia Version Same as Standard Version with Special Question Set
9255-41-71 South Africa Ver. Same as Standard Version with Special Question Set
Notes/ToDo:
- offset for top V9938 layer is hardcoded, probably should be taken from V9938 setup
- blinking on Meagtouch title screen is probably incorrect
- clean up V9938 interrupt implementation
- finish inputs, dsw, outputs (lamps)
- problem with registering touches on the bottom of the screen (currently hacked to work)
- megat5: has jmp $0000 in the initialization code causing infinite loop, is rom bad?
