That's the first "toy architecture" I've seen that attempts to define a PCI-like plug-and-play scheme... and a set of device classes that are suspiciously reminiscent of USB. :-)

Yeah, it get details of both. Also, we did take a look to Amiga's autoconfig and Z80 and 8086 interrupt handling schemes.

The TR3200 itself is inspired on MIPS and ARC (a simplified SPARC cpu for using on computer architecture courses )
