Interesting!

I've got a 2/50 with 2MB RAM :) An IBM hard disc in my SS10 has more RAM
than that!

I *think* the Sun 2 boot PROM only supported QIC11 tapes for booting.
Most (all?) Sun 3 tape drives were natively QIC24.

I net boot from a 3/260. Aside - if anyone in the UK has a 2/50 SCSI
card/memory expansion I'd be interested :)

Well the Sun hardware FAQ quotes the 3/50 at 1.5MIPS - that's a 68020 at
15.7MHz. So Sun 2s with 10MHz 68010 (16bit data bus instead of 32bit) will
be ~0.5MIPS at a guess :)

That's a *loaded* Sun 2!
