+
+ Tektronix 440x "AI Workstations"
+
+ skeleton by R. Belmont
+
+ Hardware overview:
+ * 68010 (4404) or 68020 (4405) with custom MMU
+ * Intelligent floppy subsystem with 6502 driving a uPD765 controller
+ * NS32081 FPU
+ * 6551 debug console AICA
+ * SN76496 PSG for sound
+ * MC146818 RTC
+ * MC68681 DUART / timer (3.6864 MHz clock) (serial channel A = keyboard, channel B = RS-232 port)
+ * AM9513 timer (source of timer IRQ)
+ * NCR5385 SCSI controller
+
+ Video is a 640x480 1bpp window on a 1024x1024 VRAM area; smooth panning around that area
+ is possible as is flat-out changing the scanout address.
+
+ IRQ levels:
+ 7 = Debug (NMI)
+ 6 = VBL
+ 5 = UART
+ 4 = Spare (exp slots)
+ 3 = SCSI
+ 2 = DMA
+ 1 = Timer
+ 0 = Unused
+
+ MMU info:
+ Map control register (location unk): bit 15 = VM enable, bits 10-8 = process ID
+
+ Map entries:
+ bit 15 = dirty
+ bit 14 = write enable
+ bit 13-11 = process ID
+ bits 10-0 = address bits 22-12 in the final address
