- Doing it old school! My latest acquisition for the #Amiga 500 with Kickstart 1.3: A GVP Impact A500-HD8+ with 2 MB. I replaced the broken HDD with a ZuluSCSI and am now copying Workbench 1.3 from floppy disks. Next, of course, I need to install Monkey Island (happy disk changing) 😅
- Today, I took care of the power supply of the #MysteryMachine. I unplugged all the cards, drives and the CRT and measured the 5V and 12V rails without load.Then I created some load with an old hard drive and let it run for 20 minutes – the PSU remained completely stable, absolutely rock solid. 👍
- I've made some progress exploring the #MysteryMachine. Using my Greaseweazel, I was able to create an image of the floppy disk I found in the machine's TEAC FD-55B. We were able to make the contents readable. It appears to be some kind of CP/M machine with Heckler & Koch's own MT4 file format.
- I have dumped the 2764 EPROM labelled ‘MOS 2.0 0.4/10’ with my TL866-II+. To be on the safe side, I did this three times and compared the results with HxD.
- Here are the photos of the Seagate ST-412 hard disk. It is interesting to note that it appears to have a type of daughterboard mounted on the drive electronics, with its own Z80 processor. I suspect that the daughterboard is the HDD controller.
- Over the last few days, I've had a little time to explore the #MysteryMachine further. It seems to be completely bus-based; even the PSU is a plug-in card. Obviously Z80-based. After some initial research, it could be a CP/M computer with an ECB bus. Does anyone recognise it?
- Today, I took care of the exterior appearance of the #mysterymachine and cleaned it thoroughly. Here are a few more pictures of the keyboard, the back and the bottom. I can see plug-in cards through the slots. Now I have to find the right screwdriver, because that's obviously not standard either.
- Today I rescued this gem from the rubbish bin. However, I'm not sure what kind of device it is. There is no model sticker or other clues. It obviously has a hard drive and a floppy disk drive, so I think it must be a PC rather than a terminal. Over the next few days, I'll take a closer look at it.
- Can't wait! CU there.😎

- The SwinSID nano in my recently repaired #C64 wasn't enough for me after all - so let's see what this thing can do #FPGASID - WOW! Stereo SID sound is blowing me away 🎧
- just fixed the last remaining issue of the blackscreen #C64 - 2 shorted PINs on the joystick port caused weird keyboard issues - this was a bit tricky to hunt down (btw the "bad" SID comes from the SwinSID nano - it's actually ok)
- Nice! Check out the new release from Linus Akesson #Chiptunes www.youtube.com/watch?v=Gds1...
