Getting further with MCA emulation. The reference disk now boots and tries to start configuring adapters, gets confused pretty quickly and crashes.

When you have three buddies over and you just can't agree on a four player game in MAME...turn to VS. DualSystem!

Finally making some solid progress on the Whitechapel Computer Works MG-1. This rather unusual system is based on the NS32K family, and fortunately its extensive use of many of the MMU's features has allowed me to track down and fix a number of serious bugs. Getting to this point also required supporting the Am9516 DMA controller and adding at least a high-level emulation of the μPD7261A hard disk controller, both used by a number of other similar-vintage systems.

Apart from cleaning up and merging all of the work to date, the main remaining elements for this emulation are the floppy, keyboard, mouse and cursor (the latter may be a bit tricky). Hopefully a firmware dump for the keyboard will show up soon, but I'm about to begin working on an HLE until it does.
