 |  Re: Who ported GEOS to plus/4?
In the '91 I have started to work inside the GEOS, (the result was the English version that you know), then I've gathered some (paper) documentation and other info.
First of all, I have to say that GEOS is one of the bestwritten package I've seen ever. It has a lot of genial ideas and these features are on +4 version too.
For example pictures are compressed in a GEOS-Style way, which algorytm is almost complex. The +4 version of welcome screen has embedded the M&T logo, then I suppose it was created by them. If it was only a "private" convertion by Oluf, he probably would not like to face further difficulties for nothing.
The colors managing is new on +4 version, being not present in C64 versions.
However a good level of compatibility was maintained, so that many utilities written for C64 version still work (apart the colors backgrounds).
Regarding the date, if I well remember the 01-01-90 was the default is one does not modify it.
