Hey WS.. I had one of thouse too... and I had a Sharp ZX80..
I still have a box full of Tandy computers, Amigas, Ataris.. all the old clasics..
I also had the Origanal PONG console.. rember that ?
I rember my first 'home computer' after the sharp.. it was a Olivette 086 at 6Mhz.. I had it running at 16Mzh before it overheatered and locked up..
Also a fun thought I got my P2 to run at 1Mhz last week.. Yes thats One Mhz, underclocked.. just becouse its possable.. and was a jumper set board without the book..
Have fun all,
Your techno folfy
