Great, you're back! Hey, I found a pretty nasty bug in rompage c - it's
impossible to call _pushErrorHandlER and _popErrorHandleR in a system friendly
way, because you're using a call/ret to access them, and not a jp. This means
that the code in rompage c pushes a return address, then adds the error
handler and then returns, but when it returns the z80 fetches the return
address from inside the error handler stack frame! So currently I'm fetching
the real address from inside the call instruction, and jumping there instead.
And another thing, what's the point with the test code at the end of rompage c
(displays "Yeah Yeah this is cool")? As you probably know it doesn't work,
because for example _puts can't access that line of text!

Curious,
Linus
