Then they offered a reprint service for old issues/articles. Now it seems that they've stopped that entirely, removed the web-only articles, and outsourced the reprint service.

As you might guess, the answers are yes (and no), and see above. These two issues are primarily about the HP 9000 Series 500 family. The August 1983 issue is about the hardware and processor design and packaging, and the March 1984 issue is about the software. As Joe mentioned, the 9000 was originally conceived as a sort of follow-on to the 9845 high-performance BASIC workstation. Somewhere in there the marketeers got the idea that it should run this new UNIX thing too, and so the OS developers got the idea of this lower-layer OS called "SUN" (no relation to that other UNIX vendor) that provided basic multiprocessor and multiprogramming support: multiple processes, memory management, multiprocessor-safe synchronization primitives, stuff like that. They then implemented a single-user BASIC atop that, and a port of System III UNIX called HP-UX. And, well, it's really a fascinating approach to performance from the very late 1970s and early 1980s. That first issue is largely about the design of a high-performance 32-bit CISC microprocessor based on the then-current notions within HP: it's a 32-bit microcoded stack processor, just like a big classic HP3000. Speed meant power, and power meant heat, and they needed to do something about the heat. Ever pull the CPU or memory cards out and notice how heavy they are for their size? That's because the boards have a 1mm solid copper core. The ICs are not in packages, they sit in holes in the Teflon printed-circuit base and are epoxied directly to the copper core, which dissipates the heat that the ICs generate when running. Bond-out wires go directly to pads on the printed-circuit board. That's why there are protective covers on the boards, there's naked silicon and other fragile stuff underneath. Astronomical notions are what drive the code names: SUN: the OS FOCUS: the processor chip family MONOCLE: the boot loader ("puts the SUN into FOCUS") DAWN: the 9020 (520) CORONA: can't remember, was this the 9040 (540)? That (especially the "SUN" name of the OS) is why the "solar system" picture on the cover of the March 1984 issue. At the time of the August 1983 issue, the family wasn't called the "Series 500", it was just the "HP 9000" with models 20, 30, and 40 (9020, 9030, 9040). Somewhere between there and March 1984, the 98[123]6 and 9920 were renamed as the HP 9000 Series 200 family (2[123]6 and 220, respectively) and the models 20, 30, and 40 became the Series 520, 530, and 540. I think the Series 550 came after this. -Frank McConnell
