Bunch of improvements in the device, memory and MMU handling. Re-worked the NEAT 286 chipset (ported from VARCem). Re-worked the ATI 28800 a bit, added Sierra SC1502x ramdac to VGA Wonder XL (Compaq) since it supports such. Top 384K memory handling improvements (256K top memory too) Added MCA version of MPU-401 (not tested much, however). Re-worked the SCAT 286 chipset.
