the much later turbo2
Actually, that particular Turbo2 (the z1065) isn't that much later. They came out in 89 and ran until late 1990 when they were replaced by the Glider.
The 1065 and more basic 1055 sold so well in back-stock (there were a few exclusives around at this time too, which also sold well) that Lux brought back this style as the even more basic 1070 which ran until 1995. Towards the end of it's run, it was an absolute bargain - £49.99 with the toolkit.
Hold onto that one, Michael, the z1065 is getting rare these days. The 1055's seem to crop up more often and even then, they're yellowed to buggery! For some reason, the 1055 and 1065 always yellowed heavily compared with the 1070 which didn't discolour at all.
Alex, the 561 has come up great! Good job!
