A Z80-based computer with 16k RAM, builtin BASIC and 72x78 block graphics, developed by Swedish companies Dataindustrier and Luxor, back in 1978. Easily the most popular computer in Swedish homes and schools at that time.
I added 16k memory, developed several games (yes, with 72x78 graphics), and some development tools (HJÄLPARE) that were spread through the Swedish community ABC-klubben, in an early open-source movement. Eventually me and a couple of friends developed a 240x240 pixel graphics extension that we tried to sell, without success.
Very good learning project!

Can someone comment on data throughput as a function of frequency. Do lower frequencies limit tower data rates?
There is more bandwidth available at the higher frequencies. More bandwidth allows for higher capacity.
