Pin 33 definitely appears to be tied to something in @mizerable 's photo. Must be power plane.

These may help? To me, looks like it's to the power plane, on the chips it's "v88"

Well, pin 33 on all four chips is definitely tied to a thicker trace and via as is typically used for ground or power plane connections. Visual doesn't tell us which one it is tied to, but given that the 29F800 on 7100 DIMM works, it must be tied to Power.

I wonder why? The ROM chips have a Byte# pin? The ROM chips use 33 as a another power pin? Apple left the option to put programmable chips on those modules?

Still installing Debian, pretty sure it crashed cuz I only have 196mb ram for now, switched to deb 8 and it recognized everything including network!

Here's the ANS running marathon on Mac OS, runs solid actually.

Are you doing that on the internal video, or a video card? What resolutions and colour depths are you getting?
Yeah, via the internal GPU.

I think 256 colors, at 480p not exactly sure. Ran p fine.

I have ordered a rage 128, should come soon, will let y'all know if it works.

Debian was able to see my ati GPU from my xserve, but didn't display anything, then again install still hasn't finished (slow. Needs more ram than 196mb)

It likely would have been BYTE# on any ROM in that form factor, since they would be following the JEDEC standard.

Debian 8 on the ANS!

I do believe, unless anyone else has done this that I'm the first person to run a modern OS on this thing.

It's, slow...but imma push on regardless!
