Yes, but those were 386DX 25, not 386sx, the sx had a 16 bit bus.

Sequent never did 386SX, they did 386DX

I'm running a PicoBSD firewall on a 386DX with 8MB.  (Well, maybe it's
just a screening router...).  Mind you, it's pBSD off 3.4-STABLE, not
off -CURRENT.  But I'm planning to see whether I can do it with
-CURRENT so I can get IPv6 in there too.  (I'm not using any HD at the
moment, but I may have to steal a bit of space of MSW3.11.)

Are you using -pipe?  That drastically increases memory requirements.

Certainly sounds interesting.

Back a couple of years a friend (electronics guru) and I wanted to do some
PP'ing for a little astronomy project. It never eventuated but we were thinking
of a tying the 6 odd 486's together directly via a pci to pci circuit. We wanted
SPEED though so we tossed around the idea of direct pc/pc communication via SIMM
sockets.  Idea being, chunk of ram for local processing, starting on a SIMM
boundary a circuit (running at cpu bus speed) to communicate with the other
pc's.

All highly unlikely, but logic didn't enter into it back then :)

I tried on a 486dx66, 8mb 100mb swap (I forgot to take my medication 
that day).. At some stage I got the slient reboot aswell.  So now world
builds are happily crunching away on the p90 32mb which was sitting right
next to it :)The p90 is actually in a NX (Neptune) chipset board, so
once I source a 2nd p90 I'll be trying dual cpu builds :)

Turns out that 12MB + 30MB of swap isn't enough to build world.  I ran
out of swap and the machine rebooted (at least that's what I think

'torture test' is an understatement.
