hp9k3xx.c: preliminary driver for HP9000 300 Series (aka HP9000/3xx)
|
||||
|
||||
Currently supporting:
|
||||
|
||||
320:
|
||||
MC68020 CPU @ 16.67 MHz
|
||||
HP custom MMU
|
||||
MC68881 FPU
|
||||
|
||||
330:
|
||||
MC68020 CPU @ 16.67 MHz
|
||||
MC68851 MMU
|
||||
MC68881 FPU
|
||||
|
||||
All models have an MC6840 PIT on IRQ6 clocked at 250 kHz.
