CRT 256: addon board for CRT 250, stores question roms (aka Memory Expansion board)
CRT 258: addon board for CRT 250, contains UART and Microtouch touch screen controller
CRT 260 same basic components as CRT 250 with these 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:
- DS1225Y 64K Non-volitile SRAM (Mega Touch 4)
- DS1230Y 256K Non-volitile SRAM (Mega Touch 6)
- DS1644 32K NVRAM + RTC (Tournament sets)

xx = game/version code:
20 - Megatouch 3
30 - Megatouch 3 Tournament
40 - Megatouch 4
41 - Megatouch Super 4
50 - Megatouch 4 Tournament
51 - Megatouch Super 4 Tournament
60 - Megatouch 5
70 - Megatouch 5 Tournament
80 - Megatouch 6
Not all regional versions are available for each Megatouch series
For Megatouch 4, set 9255-40-62 is Croatia
For Megatouch Super 4, set 9255-41-62 is No Free Credit
Notes/ToDo:
- offset for top V9938 layer is hardcoded, probably should be taken from V9938 setup
- blinking on Megatouch 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)
- megat5a: has jmp $0000 in the initialization code causing infinite loop, rom U38 is dumped at half size / bad dump
- for pbst30 only roms were found, it appears that two roms with graphics data were missing, using pitbossm roms for now

Pit Boss Megastar - Merit Industries Inc. 1994
Runs on standard Merit CRT-250 PCB with the following additions:
CRT-256 Memory Expansion board
CRT-254 Module (to connect the DS1204 to main board via connector J2)
CRT-243 Video Billboard board (Optional) with optional Video Billboard Keyboard
From the "PIT BOSS MEGASTAR CHIP SET UPGRADE KIT" Program No. 9243-XX PM8938 Owner's Manual:
This kit updates the Superstar 30 program (9233-xx) to the Megastar program. The new EPROM set consists of 3
EPROMS: 9243-xx-xx U9, U11, U15. EPROMs U10, U12 and U13 are unchanged and do not need to be replaced in a
field upgrade. U14 will be removed as it is no longer used.
Custom Program Versions:
Program # Description Differences
9243-00-01 Standard Megastar Includes all Options / No Restrictions
9243-00-06 California Megastar Excludes Free Play Feature
9243-00-07 New Jersey Megastar Excludes Set Trivia and includes 4-coin limit with lockout coil
