brackets aren’t really the best way to figure this out, is it? makes a lot of assumptions about human preferences that probably don’t actually hold. something like ELO might be better.
The AM-100/L we used at work until about 1988 did not have any memory protection. It was a pain in the rear trying to develop on it while it was being used in production, as you could easily lock up the entire machine and shut everybody down for five minutes while it rebooted. But our current ERP system is still derived from a Windows port of a DOS port of the original system I built in Pascal on that AM.
We've still got the old machine sitting in a dusty storage room. Last time I tried to fire it up, which was probably more than twenty years ago, it wouldn't boot due to bad RAM. I called the company to see if I could get any documentation on it, as ours was long gone, but they told me they had no interest in helping.
They didn't (not for AMOS at least, the UNIMOS capable machines had an external MMU).
"AMOS is also a strict real-memory operating system, which is to say there's no MMU, and programs were expected to be fully position-independent and run wherever the monitor ended up loading them. This makes it fast, but also makes it possible for jobs to stomp on other jobs, and it was not uncommon for busy systems to crash on a regular basis."
68451 or a custom SUN-like (SRAM, kind of like a PDP11) MMU, there was a guy who went around Silicon Valley in the mid 80s designing SUN-like MMUs for companies, they were all different, and some were broken (couldn't protect user space from kernel space).
68000s however had a problem: they couldn't return correctly from a page (MMU) fault (68010s fixed that) for a pre-VM (pre BSD or SVR2) UNIX world - however you could get around this with a few smarts
yeah, that's rather a pain though and it effectively leaves one 68k frozen while the other services the page fault - it means you can't run another user process while the page is being read in (because it too might cause a page fault)
Because people keep buying their generic hardware, and random youtubers keep recommending their stuff.
How about we just stop buying anything logitech. What other peripheral company has squandered their resources as much as they have, completely refusing to innovate?
all the insane and/or speculative projects that i never did because they would require heavy lift but with vague outcomes are now in progress. it's glorious.
If all you needed to do was vector math, a dedicated vector processor with eight cores that are capable of running as fast as the extremely wide bus could feed them with data is the way to do it. You couldn't buy anything close to it's capabilities (for that specific task) for the money.
I remember the course we used them in being hard as hell, and the professor didn't really have any projects prepared that would really push the system.
From what I understand (may be wrong) this is exactly the reason that they stopped allowing Linux installs on PS3s.
People were buying them just for this purpose. However, the consoles were sold at a discount because Sony expected users to buy games, controllers, etc. If someone bought a PS3 alone, without anything else then Sony lost money.
So you don't dispute the thesis that the hypothetical general-purpose machine described in the comment would have needed to have been been better than the PS2?
this is just slop
