I've got an old P70 (IBM MCA luggable w/ plasma display) with a '386DX20
that I'm playing around with. Does anyone know if there's a drop-in
replacement for the '386DX? I'm pretty constrained space-wise, no room for
an interposer and barely room for a heatsink should one prove necessary.
I'm not aiming for a fire-breathing monster, just more geek points when I
boot AIX-PS/2 and Solaris-mca 2.6 on it.
Thanks!

God, now I'm envious. I've wanted AIX-PS/2 since I knew it existed, but
hadn't heard of Solaris-mca. Is that regular Solaris for i386, or is it a
special version?

Take a look around at http://www.ps-2.org/home/site/axis for answers...

Errr, good question! I'll have to check here in a few minutes, after the
kids are in bed.

PGA. I was pretty sure it was, but the more I thought about it the less
certain I became... :/ I think I'm going to solder a socket in under the
oscillator too. I'm not sure how much slack there is in the planar, but the
box's already been butchered, so I don't feel like I'm damaging an
irreplacable machine by 3733+3 0v3rc!0ck3r mods. On second look, maybe I
won't. It looks like about a day of disassembly to pull the planar!

Bob,
Had to ask. I had somewhere a 386 to 486 upgrade around but it's
plcc.
Thought I could help

Thnaks for the effort. I'm afraid it's going to have to be a pin-compatable
drop-in-- there simply isn't room for anything else.

To my knowledge most of the 486SLC chips work with
386 MCA. I don't have a P70 so I can't say for sure.
IBM 486DLC2
IBM Blue Lightning ?
Kingston 486/SX Now! 25Mhz
Cyrix 486Drx2 (AKA DRUsup2)
TI486SLC
Evergreen?
You might check the comp.sys.ibm.ps2.hardware
archive on google for the P70.
In my archived files I have some info I could send you if
you wish.

These are true 486's and therefore require 486 sockets. To use them in a
386 board, you need a giant proprietary interposer. Fine when you have
plenty of room, like in a Mod 80 tower, but not so good in the P70.
Kingston 486/SX Now! 25Mhz
Not familiar.
Cyrix 486Drx2 (AKA DRUsup2)
Works just fine.
TI486SLC
Evergreen?
I think these might be too big.

TI made a series of high powered 386's. They were supposed to upgrade
your computer to 486 capabilities. They were better than the Cyrix
chips, although, I don't recall why.... cache I think.

Sure. It's the Cyrix 486DRx^2. A 486 that runs in a 386 socket. You can
find one around if you look hard enough. They are explicitly supported in
the P70, but I don't know if they have a cache enabler that will work
under AIX/2.
