…without doing anything fun.

The 6840 emulator seems to work with everything I’ve thrown at it, but when there is a need for an extra timer to run the external clock source, things tend to slow down quite a bit. Still, better that than it not actually working, and I may be able to squeeze a little more performance out if I really had to.

To try to make my life easier later, I’ve put together a rather quick and dirty skeleton structure for triac banks (connectors for external circuitry or solenoids), so each driver can now drive 32 (4×8 banks). This is just so that different games can configure them to their own ends (payslides or hoppers), rather than having to have different PIA handlers. My next trick will be to try to probe why the serial link is still stuck in a loop, and to attempt to add the discrete sound circuit (help!). Admittedly this will be yet another CPU hit, but seeing as it only triggers when something’s wrong, it shouldn’t be all that bad. If inspiration strikes me, than the lamping will be fixed up too, but I do think that I have the inputs sorted.
