I was on my way to college and walking through Smiths in Walsall taking a shortcut from the bus station and there sitting in a glass case in the middle if the shop was a ZX81. It really was a Waynes World kind of moment ' Oh yes it will be mine '.
https://www.youtube.com/watch?v=a7jJnwEeiU0I kinda had the same feeling about the VIC 20 in the window of Dixons in Birmingham as I travelled to work. In those days I think most that sat by me on the bus must have thought I was bonkers as I read pages and pages of machine code.
And the Amiga... I was transfixed by this full screen animation of a female eye just blinking at me in Lansdown Computers window in Bournemouth.
I guess when you're addicted you gotta have your fix. Still the same today. Probably too late to get help.... I have a GVP Turbo on the go in the next room on a 500 and I'm raring to go. As you do.
PS Here is my ZX81 with expansion and keyboard that I got from a Sinclair Exhibition in Edinburgh... That was a long journey from the Midlands I can tell you. But worth it.
