Welcome Andrew!

Whatever the motivation to come home to the QL, you have friends here

Hiya Techy!

So impressed with your assembly and execution of these great little devices, I'd love to purchase another 2 units for my remaining QLs - but only after others here have the opportunity to pick one up for themselves!

Ah yes, that's the thread I was remembering - thank you! I see now that the zip archive I uploaded only included the original plus a more readable version of Tony's original EQN file.
