Mike you are right os 3.9 is actually a hack/patch fest lmao. Thats why they called them Hack and patch instead of Haage and partner.
No, not really. While it is certainly true that 3.9 included many utlities that came from Aminet, it is also true that 3.9 did not contain patches. The typical Aminet patch has been developed by ignoring system specs or without enough knowledge of the insides of AOS, and is hacked into the system, 3.9 improvements were made from the 3.1 and 3.5 Os sources. Nothing had to be patched - the software was reviewed, improved and corrected. 3.9 math libraries is such a case, the workbench was created this way, so did the FFS.
It is not a new model to buy third party software and include it in the Os. AREXX was such a case (except that CBM never paid for it, shame on them!), AmigaBasic is such a case, the NanoEmacs is, BRU is... So, don't look down on 3.9 because the added software did not come from CBM. It could not. CBM was dead - for the better.
