Hey Al,
I haven't looked at the MAME stuff but if it uses an NEC 765 then it
probably won't be the same. The signal list is quite a bit different, e.g.
only 5 non-contiguous address bits are used. Real weird.
I'll take a look all the same.

Have you looked at the displaywriter MAME driver?
The floppy uses an NEC 7
Also I should note that I live in NYC, so if anyone around these parts has
a working Displaywriter I am willing to drive a bit and bring my portable

On to the next challenges.
