- Yes, the hp300/hp300 directory on net-2 should give you a running start.
- Much of what is ifdef'ed under "hp300" or labeled as "hp300 code" is really
- generic 68k stuff (sorry about that!) The pmap module and assorted VM
- related goo should work on a 68030 and, in theory, it would work on a
- 68020/68551 combo (though it was never tested). 4.4alpha also has support
- for the 68040. The pmap code was oriented toward the lowest-common-denominator
- HP MMU which means that many features of the 030/040 MMU are not used.
-
- Of course, this is the easy part, doing device drivers is where you are
- going to spend most of your time...

- 68040 based hp300s are currently the main development machines at CSRG.
