@koronkebitch Hm, I'm not sure if I want to be reminded of all that aspect oriented stuff from my phd again .

@koronkebitch There's an old book about storage media on my desk and one of the authors is Anton Stepper .

Ordem e Progresso!

@behindtheconsole Regarding the MX300, a few people on the VzEkC forum might have an MX300, at least there were some discussions in 2022. I hope I'm not simply proposing things you already tried...

@behindtheconsole I think I have a Multibus CPU and ethernet board from either an MX300 or MX500 with NS32532 CPU here. No idea if these still work and I don't have the rest of the machine, but I would certainly donate the boards for your effort.

I would expect that there is an interface card required on the MX300 side, too – do you have that one?

I guess you know Udo Möllers NS32k web page already? http://cpu-ns32k.net/

@behindtheconsole Whow, this looks like a very complex AMD bitslice-based design. It seems to have 32 MB of RAM, quite a lot for 1989!

A paper about the machine can be found at https://dl.acm.org/doi/pdf/10.1145/74925.74947

By coincidence, my former boss Peter Marwedel and his students at Uni Dortmund designed an ASIC implementation of the Warren Prolog virtual machine in 1989/90. I have two of the surviving chips and made some die shots, unfortunately most of the documentation was lost.

@CyReVolt Yeah, I'll definitely try to open it tomorrow. There are no visible screws, so I expect this to be a bit fiddly...

@CyReVolt No, it's still in one piece. The USB C port takes 12V, the included car charger with USB-C plug warns against charging your phone with it. So I'm rather careful here, this might be some very special hackery :).

@streetartutopia Somehow this reminds me of this even more horrible picture…

@CyReVolt Hm, that thing doesn’t seem to have a USB-A port, only USB-C for power, audio out, camera in and micro SD…

@mxk Yes, the official description is "iMars 11,26 Zoll Bluetooth MP5 Player [...] with Carplay, WiFi, FM transmitter, and GPS". It has a 1920 x 720 widescreen.

I bought it for the hacking value, of course – this might be the basis for a nice RISC-V based Cyberdeck. If it turns out to be useful as it is, I might buy another one for my 25 year old A2...

New 33€ widescreen RISC-V machine has arrived (with an F133 Allwinner D1-based single core RV64 SoC and 1 GB of RAM)...

Let's see if we can fix the ACSI DMA interrupt problems in the Hatari Atari ST emulator...

@CyReVolt Are you going?

@BR24 Und keiner kommt vorbei, um bei mir was zu waschen...

@derSammler Nice… my two 255 Alphas still need repairs, I hope it’s also just some caps that need to be exchanged…

@russ Here in Germany, we start late (mid October, but then we have a summer semester running from April to July), so this would work for us. Luckily I'm on my sabbatical in the winter (and my OS Engineering course runs in the summer anyways)...

@brainwagon Same here, but I would love to also have one of the original sets published by AT&T...

@mjturner @stiefkind @internetarchive And the heise/eMedia bookstore had all the good stuff...

@haupz @mntmn Ah, nope, it must have something to do with chocolate bars.

Remember the 1980's TV spots for Milky Way? "Er schwimmt sogar in Milch"
