- a2video: Fix IIgs monochrome confusion (#15157): C021 MONOCOLOR does not affect HGR, it converts all video output to grayscale, but only when using composite video; C029 NEWVIDEO bit5 is documented as only affecting DHGR, but it also affects HGR when C05E 7M timing is active. Improve more video timing (#15247): Emulate softswitch-specific delays; delay visible effects of various video softswitches, matching hardware; some transitions show glitches on hardware; these are not emulated, so timing is approximate; improve read_floatingbus(); replace four implementations with a cleaned-up shared one; remove dependency on m_maincpu->total_cycles() so video scanner rate remains constant around CPU clock changes; fix off-by-one bugs with incorrect addresses during HBL; remove hard-coded two cycle compensation for softswitch delays; latch C02B LANGSEL during vpos wrap; also fix Zip Chip on 50Hz apple2e machines; fix off-by-one wrapping hpos.

- mb87030: Several bugfixes and a massive speedup: DREQ was not always dropping at the end of a SCSI transaction. This was causing data to get blasted to DMA before the chip was set up in some cases; the transfer counter could underflow when SCMD_TERM_MODE was in use; SCMD_RST_OUT wasn't actually resetting anything; several delays were checked against the datasheet and found to be off by an order of magnitude. This was making SCSI-1 perform like floppy disks; mpc2000xl and mpc3000 now have fully working SCSI. Both machines can format a disk, save and load data, and read CD-ROMs error-free. Previously they were struggling to even select a SCSI target, let alone send commands; additional testing: partitioned and formatted a hard disk on x68000 and I was able to load and run utilities from HDD on fz20m [R. Belmont].
