An earlier prototype has much the same chips, but no big ARM logo.

I think VLSI were the first ARM licensee - there could be an ARM in there, and given the label, I think there must be. Perhaps needed to setup the board for the PPC to boot.

From Twitter comes a few clues:

Apple not the designer for these, Daystar.

A "real" PowerMac 6100 of the same era has no VLSI chips at all.

Similar era 68K Macs have lots of VLSI chips but nothing marked ARM.

Any vintage Apple buffs that can explain the ARM logo on this Macintosh Processor Upgrade Card (PowerPC 601 PowerMac, circa 1994)? I know Apple & VLSI were seed investors in ARM. Do old PowerPC chipsets have an embedded management core?

Very accessible technical description of Signal's new remote attestable contact discovery service

It's really good research (and glad they also explain it to a non-BT-internals-savvy audeince.) Although blending multiple CVEs on different platforms into one trendy name seems pretty cheesy to me.

For technical details of "BlueBorne" Bluetooth vulnerabilities, skip the cyber-waffle on the "exploit homepage" and get their (really clearly written) paper as a PDF:

Wish digital book publishing would become a bit more like music publishing. Seems easier these days to buy lots of music from the artist or a small label.

For ebooks increasingly the only sellers seem Amazon/Google scale. Not to mention the DRM.

I wish more chip datasheets did this: Equivalent circuits for each pin in the pin description table.
