KGMD, & IIRC several others distribution are those I did not use because of their size and I only had a 4MB 520STFM at that time.
Furthermore, at that time Window 3.0 and family was running and multitasking was all the rage. So that drive my need for it on Atari.
I was happy that those distributions came out because it was then that I started to manually install Mint without an installer.
Soon I found out that to get GEM multitasking was a very simple task.
1. copy MINTNP.PRG ( for no memory protection) to AUTO folder
2. Make a MINT folder on C: root and copy all the supporting XFS, XIF & XDD there.
reboot and BOOOOMMM..... and you have a multitasking GEM
. No rocket science, no installer needed.
Trick was to disable all PRG in AUTO and test which one needs to come before or after (or just chat at the BBS
at that time)
Later it became easier may as of v1.15 or may be later, because some bright idea geek came up with putting everything in a folder based on version number. With it just copy that folder from the distribution to the C:\MINT folder and of course that MINT.PRG to the AUTO.
So I do not understand why ppl need an installer for GEM multitasking. Till today I do the same and it works.
Sure AES is added now, networking needs extra files and parameters but that come later and easier once your base is there.
