I had an SE/30! It was a big upgrade from my Mac Plus, even with the external floppy drive, because I could finally compile Pascal code without having to swap discs. All of this was a HUGE upgrade from my //e with only one drive where I had to swap floppies for Apple Pascal constantly.
The SE/30 was a seriously useful computer and a ridiculously fun machine to use every day.
I had a Mac Plus and found a card that would clip-on to the 68000 and takeover the system at boot time. It had a fast 68020 and 68882 math coprocessor on it. It also came with a fan to get the extra heat out of the box. Ran great. Good times.
