Just acquired a NeXT 68040 cube computer. It's way cool, but the responsiveness
is unimpressive - I'd call it pokey.
All 16 RAM slots are full for 16MB, but sixteen 4MB RAM sticks may help the
speed.
It has an internal HD, as well as the magneto-optical drive.

Does this interest anyone?
About 16 inches by 22 inches, looks to be in good shape.

I think many people would be interested. With an appropriate adapter,

Yes, there does appear to be a name for them: the 163 connector.

Once again, there's no legitimate explanation for this sort of nonsense,
