One of my friends had an Armstrad, it was marketed by Schneider (local electronics manufacturer) and called Schneider CPC over here. It was a nice machine that had a faster CPU, more colours, builtin tape or disk drive and a much better BASIC and assembler/machine code implementation than the C64 (and was even cheaper) but sadly it came without hardware support for scrolling and sprites which made it difficult for game developers to use its otherwise good features to the fullest. While static pictures or scenes with not a lot of animation looked better on Armstrad than on C64 due to its larger colour palette (27 on the Armstrad, 16 on the Commie), scrolling of moving objects usually was quite jerky which often had an impact on gameplay.
However, it also had a number of decent games that I really loved to play with my buddy. One of them was Bomb Jack, the Armstrad version was closer to the arcade original than the crappy C64 conv and also much faster.
Later on Armstrad released updated versions of the CPC with hardware scrolling and sprites, more colours and extra RAM but they came too late to be successful. These machines shared the fate of the C128 which also went the way of the Dodo not too long after its release. The new Armstrad versions and the C128 were meant to prolong the live of the 8bit home computer scene but came out only a year or two before Atari and Commodore also released the first 16bit micros so most customers went for the latter and only very few software houses could be bothered to create new games and apps for extended 8bit computers that were more or less doomed right from the start.
Anyone remember the Sinclair QL? I was fascinated by it when it came out but thankfully I didn't buy one (it was unaffordable for me anyway). It was the machine that helped to ruin Sinclair, later on they got sold to Armstrad and that was that...
...and there were even more obscure micro computers back in the day like the BBC Micro by Acorn, Bull Micral 30, Tandy Altair, Matell's Aquarius, Dragon 32, Jupiter ACE, Sinclair ZX-80/81, the quite horrible Oric-1, Microbee, Coleco Adam, etc. Some of them were quite successful, hobbyists were looking for an affordable home computer since the late 70s and jumped on every opportunity they got. Many of these micros came in kit form which helped to keep prices at a minimum.
