Socrates Educational Video System
Support now cartridges as selectable roms.

Thanks Lord Nightmare !

Justin: what version? Aaron says it's fine on his MSVC (I think he uses either '05 or '08).

2008 Express Edition

This also breaks Bondwell 12/14.

Maybe the nec765.c can be fixed, so both systems have no booting conflicts ?

All the change to nec765.c should do is make the Recalibrate command actually take the time it is supposed to before completion. There was one other change I've made since, that makes Recalibrate take time to perform when it is already at track 0, again, simply because the PCW does not like it finishing immediately.

Ok, from taking a quick look at the Bondwell 12/14 boot process, it looks to me as though it actually ought to wait for the Recalibrate/Seek function to end before it goes and does Sense Interrupt Status.

So, I've added code to set the execution mode bit of the main status register during a seek or recalibrate function, and moved the nec765_idle() call from nec765_seek_setup() to nec765_seek_complete(), as nec765_idle() clears the execution mode bit.

If this makes sense to everyone, I'll go and commit it to SVN. I have no software for the Bondwell, so I can't test it any further than it complaining after wanting a system disk. The PCW driver still works with this change, and I also quickly tested the CPC and X68000 drivers, just in case, which also seem to still work.

I've commited the small change I made to the upd765. I can confirm that Bondwell 12/14 will boot CP/M now, without breaking the PCW. Seems like a rather slow system however, although it would to be a similar speed in 0.133 also. Funky speech program on the disk, though.

I am not able to load a snapshot. Not sure, i make some mistake.

Snapshot loading is not working in those drivers.
