Sinclair QL and Amstrad CPC464

These are two really cool machines that are also part of the collection but have not tried them yet.
Sinclair QL was Sinclair's new concept machine that was very advanced at the time. It had 68008 CPU, which was internally 32-bit and externally 8-bit. Motorola 68000 family was very popular for mini systems and had a very powerful instruction set. QL came with BASIC and I believe some built in applications. Its kernel supported multi-tasking. Very cool concept and piece of technology at the time. However, from what I heard the first version of ROM was buggy and there are delays in actual release. It also had infamous microdrive tape system that was not very reliable. Soon, Atari ST and Amiga computers dominated MC 68000 arena. On higer pricing there was Machintosh 128K and 512K. So QL never really made it. One peculiar detail is that the guy who started Linux movement and made Linux (Linus Torvalds) had one of these.
Amstrad CPC464 with built-in tape was a very nice Z80 based system. Amstrad was famous for their integrated and inexpensive systems (hi-fi, audio, computers). They eventually bought Sinclair and they were making late Spectrum versions. CPC464 (there were also versions with built-in 3" floppy, CPC664 and CPC6128) was one of the fastest Z80 8-bit systems. It also had a very nice Locomotive BASIC that was really fast. I remember running some benchmark programs writen in BASIC on my neighbouor's CPC464 and my brothers IBM PC XT clone (4.77MHz 8088) and CPC464 was faster. Also had nice graphics and Amstrad was offering decent monochrome and color monitors. Though, it was a very nice system it also showed little bit late. It was a popular system, but soon people had cheap 16/32 bit systems from Atari and Commodore (ST and Amiga).
