- So is the rest of SVR4... I know. I ported the signal component
- to a non-UNIX OS as part of our UNIX emulation library. Workable yes,
- do-able yes, painful to port YES. Mind you that USL is shifting to a object
- orientated design, with C++ as a possible systems language some point
- in the future ( from my ATT OS internals class ). Done as modules, the
- changes are clustered in a few routines, it's finding the locations to
- change that's difficult.

- Fine. Not any bigger problem than serial/video card or tape drive

- I agree, see previous postings. But we as a user communitee have more
- time and more incentive to try this chore than CBM does. I'd take a crack
- at it, but my skills are not in graphics, they're in process scheduling,
- tuning, security, utilities ... that kind of rot.
