Thanks. I've got a similar brain to yours. I've been trying to use Fusion 360 and going through the tutorial videos. I got a little way further. The main problem is that there's a limit of 10 projects for the free version. The Bambu slicer is based upon the Prusa one, but with a better interface and...

Phew! At last.

After a slight hiatus yesterday due to Christmas Day I'm back looking at 3D CAD software for the 3D printing. What do other people use? I imagine that the ST case recreation would need something highly capable and reasonably easy to use. I'm just finding all the packages I've tried so far "get ...

The thing is that the original PET was designed as an HP scientific instrument control computer competitor, the idea being that you would link everything via the serial bus in a similar way to the IEEE bus HP used, so you wouldn't need slots. The TRS-80 Model 1 was a cost-reduced "home" co...

Given that in the early home brew computer era machines were generally a backplane with cards it's not surprising that the Apple II had multiple ones.

*grumble*

Maybe the trace is broken, but it's not obvious.

In other news.... I've fitted the crystal oscillator in place of the broken clock circuit on the OPD floppy interface board and I'm now getting a good clock. I await the ROM image now. IMG_3505.jpeg I've also managed to create a 3D model and print it. After breaking FreeCAD after placing only two pr...

You too @rubber_jonnie !

Well, holding the ALU's reset pin low does nothing at all. The bus activity is the same, so I think that the technical term is, it's knackered.
