Same! I had the Spectrum +2A model, which had a bunch of issues running older software. The OCP Art Package didn't work at all, so I ended up writing a really awful drawing program in BASIC. Figured out how to poll the mouse, detect button presses etc. I drew a toolbar on the left of the screen depicting squares, circles etc. If the mouse button was pressed within one of those, the drawing mode was changed. That would let me draw the objects on screen. That was also where I learned what sin and cos "really" did. Never got the bucket fill to work 'properly' - didn't know if BASIC 'gosub' supported recursion, and I can't even remember if I tried.
