The rebirth of a simple 42 microcode assembler after 30 plus years.

Show all headers | View raw

Hello all,

Some months ago David May published some documentation describing the Inmos 16-bit simple 42 prototype Transputer (documents are located here: http://www.cs.bris.ac.uk/~dave/transputer.html).

Included in the data was the instruction microcode (or vbc) for the simple 42. It was a complete listing (well as best as I could work out at the time).

Anyway, I thought it would be fun to write a simple 42 microcode assembler (otherwise known as 'vbc reader' to ex-Inmos employees) and see if I could assemble the simple 42 microcode available on Dave's website.

Now available on my website (see link below) is a simple 42 microcode assembler tool (win32 console application) which can generate a ROM output file (in C header style) using the simple 42 vbc microcode. Have fun!
