ah yes

If you're learning about PowerPC and wondering where the "Books" (1, 2, 3s, 3e) are: They're in the Power ISA specs. A rough timeline:

- 1990: IBM introduces the POWER Architecture
- 1993: The AIM Alliance (Apple, IBM, Motorola) introduces PowerPC (aka. AIM PowerPC). Apple and IBM build computers based on these shared chip designs
- ~2007: IBM and Motorola (now known as Freescale) get back together to introduce the Power ISA spec, 2.xx, which unifies what they've each been doing separately.

Power ISA 2.xx consists of multiple "books":

- Book I: the User Instruction Set Architecture, i.e. what userspace programs can rely on
- Book II: the Virtual Environment Architecture, which details memory access characteristics, caching, etc.
- Book III: the Operating Environment Architecture — but there are actually two of it:
- Book III-S: OEA for Servers, continuing IBM's tradition, including LPARs
- Book III-E: OEA for Embedded, after Fsl's tradition

Power ISA 3.0 unified Book III

IBM and Motorola/Freescale/NXP seemingly never managed to keep their cooperations alive, so you had AIM which developed PowerPC "1", Power.org which developed Power ISA 2.xx, and the OpenPOWER foundation, which developed Power ISA 3.xx, but by then NXP had moved on to ARM64, it seems.

@domi @famfo microNLNet goes brrr

@famfo the hot new data structure in *checks date* 1955

@a1ba a linux distro that runs on a single architecture, is that even a real distro?

@starstorm_x1 @prahou the trick is to get used hardware from the trash

@dillo i should repeat that on my PowerPC desktop (128 MiB RAM, 400 MHz CPU clock)

beware

@dalias a bit of a different issue, but it reminds me that the rust 'libc' crate it still stuck on musl 1.1, i.e. before the big y2038 proofing

@qsx @inthehands Java is compiled to an instruction stream designed for the abstract Java Virtual Machine and interpreted by the alternate instruction decode frontend of ARM926EJ-S and ARM1176JZ-S CPUs

weird* machines all the way up and down

(* in the colloquial sense of "weird", and sometimes in the academic sense of "weird machine")

@q66 @domi @lanodan ugh, err.. @famfo and i are probably going to get one soon, there might be a few majnframes available for hauling (in europe)

@kaia looking forward to the Venice-Salzburg channel

@dalias model cars— the remote-controlled kind?
