- In the last "UNIX review" magazine (October, p.59) the "Central Data" advertizes
- scsiTerminal Servers. They write about solutions for Sun(s), HP(s), IBM RISC,
- 386/486 systems, but may be they can prepare something for the NeXT as well ?

- PS.
- The baud rates are up to 57.6K, prices reasonable. They will be at the
- Unix Expo, booth 120.
