- The SS10 combines audio and ethernet AUI onto a single connector,
- but a custom cable is needed to split out the AUI pins to a true
- 15-pin AUI connector. Sun sells an appropriate cable, but it does
- not come with the SS10 automatically. (Several people have posted
- about this not-well-documented subtlety, and how they got "burned"
- by it.) So take heed: if you need the AUI connector on an SS10,
- you *must* order the breakout cable explicitly.
-
- As machines get smaller and smaller, and the number of interfaces they must
- support gets larger and larger, it's looking more like the back of a
- computer should just have one massive DB-style connector with something like
- 1000-2000 pins. Customers could just order the appropriate "break-out" cable
- for the subset of interfaces they are actually interested in. A number of
- "standard" cables would be available to support standard configurations,
- say:
-
-
- Sun-2 (2 DB-25 serial, video, AUI, mouse, keyboard)
- SPARC-1/2 (2 DIN serial, video, AUI, SCSI, audio)
- ...
-
- There would be server break-out cables (no video), SCSI-only, or IPI-only
- versions for people with different tastes in storage technology, even mono
- versus color video.
-
- Computer vendors could offer break-out cable upgrade programs for those
- users whose interface needs change over time. (These babies won't be cheap.
- What do you do with a break-out cable that isn't fully depreciated? Stick it
- in a cabinet somewhere? Loan it to the local university until it's off the
- books?) If you couldn't make use of the ISDN capability on the SPARC-10
- right away, you could upgrade to it later, when you phone company gets its
- act together.
