classichasclass··on First methane-powered sea spiders found crawling on the ocean floor
Freaky, except they're only a few millimetres in size and considered harmless to humans.

It would be hard for a spider of medically significant size to suck down their exoskeleton like that.

There were extensions that got around this, though. iTunes for the classic Mac OS (and I'm pretty sure SoundJam before it) could continue to play music with a menu open, for example.

That sounds like Rhapsody/Mac OS X Server (which would have been Platinum). And it is, indeed, quite snappy. I have it on a Wallstreet G3 and it runs very well.
classichasclass··on How the Final Cartridge III Freezer Works
I liked the interface of the FC3, but I always seemed to have trouble with it on NTSC systems, likely the fastloader. I ended up using ICEPIC or Super Snapshot most of the time instead.

I'm sympathetic to that, and it would make a modern reconstruction easier to create, but it's also nice to see the the rubber stamps and the other ephemera to get an idea of how the process worked. Plus, quite possibly the files in their original form no longer exist.
classichasclass··on Amiga 4000T: The Best Amiga in the World
The later non-Commodore A4000Ts in TFA, however, are much better systems IMHO than the original Commodore-badged one and far easier to get. I've got one here too, with a QuikPak '060, Picasso IV RTG and Ethernet, and it runs very well in AmigaOS 3.9.

classichasclass··on Omnimax
I spent a great deal of time at Reuben H. Fleet as a kid growing up in San Diego, playing in the science museum and watching whatever Omnimax movie was on. Didn't matter what it was, they were almost always great eye candy. Even saw, later, a Pink Floyd-themed laser light show projected on the dome. Never failed to impress.

But a multisession disc with this technique should be possible, using a data track and then the rest as "picture audio."
classichasclass··on Polish engineer creates postage stamp-sized 1980s Atari computer
I wonder a bit about the changes in architecture. New 6502 instructions are one thing, but the alterations to the memory bus to cut down on (what I assume is) ANTIC DMA might lead to programs subtly unable to run on real hardware because the timing differs.
classichasclass··on Of course the Apple Network Server can be hacked into running Doom
(author) The ANS 500 I have and that this was developed on was purchased by the University I used to work for to serve as the bookstore inventory management system. The vendor refused to support it anymore after Apple cancelled the line, but it was purchased retail, minus Apple's academic discount, of course. The University had no particular relationship with Apple otherwise.

Apple did use ANSes for many years after they were discontinued. Austin had a group of Shiners still in service for internal use as late as 2005.

The ANS does have "big computer" I/O options but it's still descended from the Power Mac 9500, which is its closest relative. Harpoon AIX has a lot of changes to support the different hardware.

classichasclass··on Of course the Apple Network Server can be hacked into running Doom
Not especially similar, aside from the bus and CPU. IBM hardware of that era was straight-up PReP and later straight-up CHRP, but Apple never adopted either for Old World Macs, and even New World Macs are an incompatible mix of the two.
classichasclass··on U.S. drops COVID vaccine recommendations for healthy children, pregnant women
The policy was released prior to VRBPAC or ACIP meeting, and no input from either. This has an obvious impact on annual formulation, but FDA staff were unable to answer questions from the panel on it ( https://apnews.com/article/fda-vaccines-covid-boosters-kenne... ).

So what did it calculate?

It's a Z80 in a cartridge and was capable of booting CP/M 2.2. But don't get too excited: the 1541 was still the 1541, so it could only run software that had been copied to a GCR disk (no directly reading MFM floppies).

CP/M Plus on the 128 was much more useful because the 1571 could read MFM disks, though it was hobbled by its architecture and ran slower than it should have.

Actually, the hardware bug was in the VIC-20's 6522 VIA; the CIA 6526 shift register fixes the bug. The (chief) problem on the 64 was the VIC-II stealing processor cycles.
classichasclass··on For $595, you get what nobody else can give you for twice the price (1982) [pdf]
Yes, for two reasons. The VIC-20 used 6522 VIAs as I/O chips, and these had a notorious bug in their shift registers requiring a bitbanged IEC serial I/O routine instead. This wasn't a big deal on a system with 5K of RAM, but it was a real problem on the 64. The 64 has 6526 CIAs for I/O, where faster IEC serial communications should have been possible, but the wiring got screwed up during board design and VIC-II DMA ("badlines") caused timing interruptions at inconvenient times, which demanded slowing it down even more. (A remnant of this is UI- and UI+ to speed up and slow down loading when used with the VIC-20, but that only works on the 64 if the screen is off.)

Commodore tried to solve this twice. The first time was for the Plus/4 series with TCBM drives which connected through the expansion port. The only drive of this type was the 1551, which was very fast, but only worked with the Plus/4 family. Commodore was going to design a TCBM interface for the 64 as well, but it wasn't really necessary as pretty much everyone had a fastloader by then. The 128 has a fixed serial bus and burst mode when combined with the 1571 disk drive, which is also very fast and doesn't require using the expansion port, but by then it was 1985 and the 8-bits were on their way out.

The 1571 is way better than the 1541, IME. It's faster with the 128, it's 100% compatible, it's more reliable and less prone to alignment problems, and it can also read MFM formats. But Bob worked on the 1541, so he loves it. :)

I don't know anything about the Ace of Aces pictured, but it's definitely not the Artech/Accolade one. $595 was the 1982 introductory price for the C64, so this pamphlet almost certainly dates from then.

And Atari, though this is acknowledged in the matrix.

Bob Russell once observed the 1541 was the best computer Commodore ever made.

There was a specific reason with the TI: Tramiel was still smarting over how they screwed him with calculator chips. Meanwhile, their home computer unit was suffering millions of dollars in losses due to greedy mismanagement and the VIC-20 was driving the 99/4A into the ground as a practical loss leader. As far as Tramiel was concerned, even acknowledging the 99/4A's existence was too good for them.

Payback, as they say, is a b*tch.

It's a fair cop against the II+ but there are other things in the comparison which are mildly hinky. I find their characterization of POKEY a little unfair, even though I think SID is superior, and the CP/M option on the C64 was nearly useless because the 1541 didn't read MFM formats. (Much more useful on the C128, but you needed a 1571 disk drive, and by 1985 CP/M was on its way out.) The keyboard criteria are also somewhat of an Apples-to-Commodores comparison, so to speak. Still, it's hard-hitting ad copy and it was Tramiel's Commodore -- he was determined to win, by golly.

After the Tomy Tutor, we started with a C64 and then later a C128. Both were in regular use pretty much through high school.

VAX power really did make big leaps from from generation to generation. The 11/750 they started with got about 0.65 VUPs and the VAXstation 3200 they ended with topped out at 2.8, over four times faster. The VAXstation 3100 M76 here, about 18 months later, makes another big jump to 7.6.
