Hi,
i have seen there is some progress on the WD 2010 (= WD 1010) controller.
The NGEN skeleton invokes "harddriv.h" and "wd2010.h" since recently.
http://git.redump.net/mame/commit/?id=29faa4ce8395ec222914c818b4e22117c8d196e6Is this controller usable?
As soon as interrupts come into play, i am stuck. An IRQ should occur whenever the sector buffer is ready.
No DMA transfers are used.Most drivers assume an ISA or XT architecture (-> P1_HDC; WD_XT), so there is no real reference to cling to.
Long story short: i can't make head or tail of the MCFG or _CB statements necessary.
Attached is an unofficial version of the Rainbow-100 driver, complete with LK201 keyboard workaround and two digit (floppy) track display for anyone interested.
STATUS: few booters start (DOS 3, UCSD Pascal and DIAG DISKs), hard disk sector transfers do not complete - see above - and floppy writes are flaky (Z80 timing or Z80 <-> 8088 arbitration).
Improvements are welcome ;-)https://dl.dropboxusercontent.com/u/37819653/BANNISTER/_March_2015_.7z--- REFERENCES* EK-RB100-TM_001_Rainbow_Technical_Manual_Addendum_for_PC100-A_PC100-B_and_Rainbow_100+_Dec84.pdf
