Still have mine. And what I learned from it hasn't become obsolete yet. Those were the days of writing everything in assembly language, trying to cram your program into what now seems like a tiny amount of memory. I recall that memory was so tight that I'd use one byte to hold two different variables. Multi-tasking? Yep. We had vertical and horizontal blank interrupts that you could use. Magic times making that machine "sing"!
