Well, real life came calling and I have to put MAME on hold for a while. Pushed most of my WIP tree to github (https://github.com/shattered/mame/commits/gitwip), key parts are not committable unfortunately.
What's in there:
- K1801VM2 core (= severely hacked T11 core). This chip has no MMU. - parts of chipset for this cpu (DEC DL11-compatible serial line unit, etc.) - new bus (DEC Q-bus with add-ons to support uknc.cpp) - new driver, ms1201.cpp (Electronika MS1201.02 single-board computer) - de-skeletonized uknc.cpp, sans sound and floppy - much improved DVK KCGD -- intelligent color graphics card, 800x480 px - qbus devices: -- DEC PC11 paper tape reader (no punch) -- DEC RX11 floppy controller with RX01 drive (HLE) -- virtual hard disk driver (not a real hardware device) -- DVK KGD -- dumb monochrome framebuffer, 400x286 px -- DVK KZD -- MFM harddisk controller (HLE, read-only) -- UKNC ROM carts -- UKNC IDE harddisk controller -- skeletons of MX: and MZ: floppy controllers
What works and what doesn't:
- ms1201: 5 of 6 tests in ROM pass (remaining test is for unimplemented printer port) - ms1201: boots and runs RT-11 SJ/FB monitors, XXDP+ small monitor - ms1201: passes DEC VKAA, VKAB tests but fails VKAH (VKAC is supposed to fail). Passes equivalent tests 791401, 791402 but fails 791403, 791404 - uknc: passes ROM tests but fails many standalone tests - both drivers run many games (text-only and graphical), see screeshots and videos earlier in the thread - there's no softlist but a long TODO list for all of the above
