Small progress from the Alfaskop project I do with Mattis Lind at Dalby Datormusem, it is the bootrom of the Alfaskop 4110 Display Unit (terminal) that tells us it wishes to boot the software over the SS3 bus. The SS3 bus is an SDLC link connected to the Alfaskop 4120 Flexible Disk Unit which also is connected to the Alfaskop 4101 Communication Processor over SS3. We plan to do the long haul over to the physical world to connect to both other Alfaskop devices as well as an emulated IBM mainframe, eg Hercules. Read more about the project here: Alfaskop emu

We are currently awaiting dumps of the operating system floppy disks for the 4120 from a museum in Denmark so we can continue to work towards boot of the terminal, both the emulated one below and the physical from the emulated 4120 via the 4101 (which also boots from the 4120). If anyone happens to sit on Alfaskop system 41 software or hardware or documents apart from what can already be found on bitsavers, let us know :-) PR for the infantil skeleton driver is coming up during the weekend.

AT&T had a similar system (6500), using their 'standard serial interface'
http://bitsavers.org/pdf/att/6500

I have one of the terminal controller nodes, no terminals and no software
and haven't found anyone who woud reply to offers to buy, even though
they list the parts on the web

They built a slightly different version that could talk IBM 3270 coax protocol

AFAIK, there are no known working examples of this system.
Memorex/Telex bought the entire product like from AT&T

I guess these kind of systems are the first to bite the dust due to the single point of failure nature of their design. We are even considering reconstructing loaders across the system to be able to boot the OS onto part we don't have access to, these are pretty well documented with schematics. With 900'000 systems sold just some 30 years ago one can only wish that some floppys are still around and will show up eventually. *fingers crossed* Unfortunately they were all installed at businesses with little reasons to store them after upgrade to PC:s or Mac:s of the office network I presume.

Thanks to the efforts of the absolute unit, Ash "Ninji" Wolf, on his standalone Psion 5-series emulator, as well as his assistance in porting over and improving his codebase in MAME, we now have the Psion 5mx showing its boot screen:

Apparently, patience is a virtue. Given enough time, it boots to the main menu, and is more or less working now that I've ported over the keyboard and touch support from Wind-Emu. Here's the requisite demo of the built-in Sketch application:

Just added a more LCD-esque palette, and fixed up the remaining keyboard scan codes.

After leaving it alone for months, I returned to the challenge of getting Windows NT booting on the MIPS Magnum 4000.

Managed to isolate the issue that was killing it, and it's now working well enough to boot, run, install software etc. Networking and EISA bus support are the next major milestones, but I'm pleased to finally report some progress.

The crossover you didn't know you needed: Mario and low-end Konami gambling hardware.
