I last left this machine in a state where it boots RISC OS 3.11 when using a bench power supply, but there was a weird video issue which meant I could only use an OSSC for the SCART to work.
Lawnmower service time today. This fan pushes out the wing as it gets faster which regulates the throttle/ fuel mixture. Really clever self design in the Briggs and Stratton. Wd40βd new oil and new fuel switch. All ready for next yearβ¦ 20 year old Β£50 mower never missed a beat.
