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
