Does anyone know of a cheap 22V10 programmer ?
or maybe a Atmel ATFxxxx programmer ?

With G540 I have programmed 22V10, 20V8 and 16V8.

I assume "direct I/O" is just writing to the output register
and reading the input register.
Is the problem that it can't be made to work, or that it is horribly
slow? (I'd expect USB writes to take about 1 ms.)

The range with pre-installed parallel ports is small, but at least
Lenevo have plenty. The range of motherboards with parallel port
headers is large - it's just not connected to the back of the PC. Then
there are lots of cheaply available parallel port cards you can use on a
modern PC. And of course it's not hard to get hold of an old PC
second-hand.
It's a non-existent problem.
And most software that uses the parallel port will run on FreeDOS (if
it's DOS based), or Win2000 or earlier - which is easy to install
without any sort of activations to cause complications (now that XP is
hard to get as a new license).
VMWare can let a virtual machine use the host machine's parallel port
directly (I don't believe Virtual Box works with parallel ports,
unfortunately).

would have a parallel port and do the job, so it's not a completely
