Today, I finally had time to take care of the #MysteryMachine again. I removed the HDD and dumped it several times using David Gesswein's MFM emulator. The hard drive seems to be in perfect working order. Now I'm excited to see what data treasures await me there.

Idk what type of car this is, but I think I've seen e-bike tires thicker than these tires 😂

Today on Sea Island I saw a real #MysteryMachine, painted almost exactly like the Scooby-Doo van. The RL one had #ScoobyDoo on the left side.

Also seen: a man on tbe #SkyTrain wearing an #AnthonyBourdain T-shirt

Scrappy Doo was into some dark shit.

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. With the help of some very sophisticated guys, 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.

Here are the photos of the Seagate ST-412 hard disk of the #MysteryMachine. It is interesting to note that it appears to have a type of daughterboard mounted on the drive electronics, with its own Z80 processor. The data lines are then looped through and connected to the floppy controller card. 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's a system I've never seen before. 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 various plug-in cards through the ventilation slots. Now I have to find the right screwdriver, because that's obviously not standard either.
