That's good! You might want to set up your emulator as a Master 128, which will run in a better graphics mode.
The file
D.RPA1C which is also on the disc is a preamplifier for connecting a Chinese "red stylus" cartridge to a record player with an EL84 + selenium rectifier amplifier. The components are dispersed about the screen, but nothing is wired yet.
For a real treat, I'm just working on a BCP version of my "Pocket Particle Accelerator" right now ..... in case you found the "B9A21" footing and wondered what it was doing!

The BBC Micro User Guide and Advanced User Guide are definitely available online.

Oh, yes! And you can only fit enough source code into RAM at a time to assemble about 2KB of machine code. The main development work is now being done using the excellent
BeebAsm, which I can't praise highly enough; but I also came up with a way to "keep it real" by building all the code on a real Beeb. This is orders of magnitude slower than doing it all on the host side, though .....
