GeckOS 2.1 released

I had to do some digging into our archives to see if we ever covered GeckOS before, but apparently we haven't - and that's a shame. GeckOS is a pre-emptive multitasking operating system for the Commodore 64 and the PET, and should be easily portable to other 6502-based machines, and offers multithreading, TCP/IP networking, and more. Version 2.1 has just been released, and it adds a ton of new features and bugfixes.
