- As a NeXT employee once pointed out, given the choice of adding
- cost by:
-
- 1) Adding special purpose hardware dedicated to a given task or
- 2) Throwing in a few more processors on a multiprocessing system
-
- Which would you choose? Have you tried using the Hayes ISDN
- connector while running ScorePlayer? Special purpose hardware is
- always a stopgap measure until the CPU can catch up and subsume
- the tasks.

- Unfortunately the Amiga graphics and sound hardware is looking a
- little long in the tooth these days. It certainly reaped an
- advantage for a while, but it VERY difficult to keep special
- purpose hardware up to spec with the latest and greatest general
- purpose. I'd rather see NeXT put in sockets for a few more CPUs
- and let ME decide what they'll be doing!
