@Setok@attractive.space GEOS for the C64 and Apple II was a GUI for 1 MHz 6502 machines back in the day – without slop coding... Apple's IIgs had an even more advanced GUI using a 65816 CPU running at 2.8 MHz.

@flexion@oldbytes.space Was it really sold? I had the impression it was mostly a gift for "good customers" (which we weren't at my university back then, we mostly had Sun and DEC hardware)...
There's a new PDP11 extension card for Apple II computers based on the J-11 and a Tang Nano FPGA board. Whow.

I would usually not post news about royalty as I couldn’t care less. However, in the two years I lived in Norway, I had the impression that King Harald was loved by the Norwegians and was one of the few down to earth royals. I remember an old photo showing him riding the Oslo subway with ski. All the trouble with the son (from a previous marriage) of his daughter-in-law seemed to be a strange disruption there.
King Harald passed away this morning at the age of 89. RIP.

@bigmike@ruhr.social Not exactly what you want, but it should be possible to run the Einstein Newton emulator on recent phones with acceptable performance. I could imagine that it’s feasible to also run it on a minimal Linux kernel + userland configuration.
https://github.com/pguyot/einstein
The NewtonOS source code was never published (and hasn’t leaked as far as I know), so a direct port is currently not possible without putting a lot of effort into decompiling the code.
Unternehmer Nikolas Stihl (bekannt durch Motorsägen) fordert die Abschaffung der 35-Stunden-Woche [1].
Sein ererbtes Unternehmen hat ja schon Erfahrung mit kostengünstigen Arbeitskräften: "Ab 1941 stoßen Zwangsarbeitende dazu, darunter Kriegsgefangene. Insgesamt sind es bis 1945 100 Männer und Frauen aus dem westlichen und östlichen Europa, davon etwa die Hälfte aus der Sowjetunion." [2]
Wie unsensibel kann mal als Unternehmer noch sein?

Replying to
@CyReVolt@mastodon.social That would make sense, but instruction decoding seems to use a PLA in the RISC-I instead of a net of combinational logic gates (see p. 6 of [1]). Using redundant opcode encodings would then not result in a reduction of chips space, I think.

I think I have some other PCBs on my list that I wanted (though I have too many hardware projects lined up already...), so it might be a good time to send another order to JLCPCB... but that has to wait until my vacation is over (in early September), JLCPCB is simply too fast...

@CyReVolt@mastodon.social NTNU had about 4,000 applications for 600 places each year (over all programmes in CS/CE) when I was working there, so they definitely had to filter. They can certainly still fill all seats right now, but you no longer need to be absolute top-notch to get in.
Admission requirements for the five-year integrated Computer Engineering degree programme at NTNU in Trondheim are being lowered for the fourth year in a row. Apparently, the uncertainty due to the AI craze is dampening young people's interest in the CE programme.

I never heard about this when I used an ST as my main computer – but then I got a Sun 3/60 in 1992, so the ST was not that interesting any longer...

@david_chisnall@infosec.exchange @shac@ioc.exchange Now that's an interesting discussion – do you see compartmentalisation within a monolithic kernel as an alternative to building (more efficient) multi-server, microkernel-based systems or do you rather think of it as an orthogonal approach?
Replying to
@hanshuebner@mastodon.social I think @brouhaha@mastodon.social had the right idea.
The SystemVerilog source file included mentions a "DCJ11 TangNano interface by nanja.info [...] PSRAM interface module [...] 4MB RAM" in ram.sv.
The top.sv module is connected to:
DAL<21:0>, BS<1:0>, AIO<3:0> (J11 side, data/addresses multiplexed)
and
Apple II Data D<7:0>, Apple II /IOSEL, Apple II R/W
plus the PSRAM.
There also seems to be peripheral emulation (or addr. decoding) for a DLART and a PC11.
Now where do I find a J11 module? 😀

@LangerJan@chaos.social Ein Kawai MR270 aus den (vermutlich) späten 90ern. Ist ziemlich sicher mit Silberlack oder einem Stück Draht fixbar, vorher muss es aber noch komplett entrostet werden. Die Schaltpläne und Serviceunterlagen hat Kawai mir freundlicherweise zugeschickt.
I'm investigating the original Berkeley RISC-I CPU out of historical interest and wonder why some instructions use more than one opcode (e.g. LDHI uses 16 opcodes 0x70...0x7F). I can't see why this is necessary – is this an optimization or am I missing something here?
Details seems to be provided in Corcoran, G.T., "Using ISPS to Specify the RISC I Architecture and Implementation," Master's Report, UCB (Dec. 1980), but I can't find this online.
