is it specific to the (unavailable) ECS P5TX-LA BIOS?
- p5txla: Rage VGA chip sets up screen with 8x1, making MAME unresponsive.
Needs x86 VGA legacy map bridge to fix.
- pf2012: cannot be coined in (lockout read? ISA irq? sound CPU comms?)
Enters into gameplay if set to free play;
- pf2012: verify ISA irq 7 source (particularly ACK, PORT_IMPULSE(1) won't work),
pinpoint coin counters output and verify tc0510nio write 4 EEPROM style write
on coin insertion;
- pf2012: Should show bootscreen when Voodoo fbiInit0 bit 0 is off (vga_pass), cfr. GH #11343;
- pf2012: boots in service mode the first time around, needs default EEPROM set;
- pf2012: service mode RTC item always initializes to 0 for hour count;
