[Vm-dev] VM porting help: ioShowDisplay always called with empty (all 0's) buffer

This particular question could be answered by the documentation found on
https://isqueak.org/ioForceDisplayUpdate or

However I discovered that isqueak.org was down due to a PHP change. So I
decided as one of the owners of that site to pull it back into my main
server infrastructure and update the software to more current versions,
along with supporting HTTPS.

I looked at turning user registration on, but in testing that feature
within no less than 5 minutes a spam bot registered and started creating
garbage pages!

Thus if anyone wants a user id/password please contact me directly.
