My first program
I found the tape containing the program I mentioned in my last post! Yay! 
Unfortunately I can’t find a Vic-20 tape drive that works. Boo! 
So far I have tried three tape units - one has a busted connector (loose wires) which I should be able to fix when I can find my soldering iron. The second did work for a moment, but now the motor doesn’t work. The third unit has the wrong connector for the Vic - I think it is a Plus 4/C-16 connector.
Time to dive into the back room again and hunt for a working tape drive - I know I’ve got another three or four units at least. Somewhere…
Update:
I found a working tape drive but it appears that the start of the tape is corrupt. I can load stuff saved after the initial loader, but it appears that I wrote a boot-loader which then loaded the letterhead and/or SpeedScript. Maybe I have a copy on floppy somewhere… :-/
