No one mentioned the Amstrad CPC464 yet then.. a natural progression from the ZX80 81's..
Ahh yes Jet Set Willy and Tankbusters with vector graphics, Defender to name but a few.. those elusive infinite lives pokes.. and having to load data into screen memory before shifting it down in memory to address zero, just so you can put in your own little hacks :-)
Then the 8086 came out and all the fun went out of life..
And this is where some have ended their days..
