The later non-Commodore A4000Ts in TFA, however, are much better systems IMHO than the original Commodore-badged one and far easier to get. I've got one here too, with a QuikPak '060, Picasso IV RTG and Ethernet, and it runs very well in AmigaOS 3.9.

The only thing about the ESCOM and QuikPak Amiga 4000Ts that were not great were the floppy drives, which I’m told were modified PC floppy drives. They worked, but weren’t the most reliable either.

Modified to spin at half speed, that was the only way to make Amiga read HD floppies with its 9 year old never updated floppy controller.

Honestly, I’m amazed it took Commodore so long to properly support high density floppies. I’m pretty sure they stuck to the double density 880K GCR format right up to the 4000 series Amiga. Meanwhile, Atari was supporting high density media in some capacity as early as 1990 in their higher end systems.
