I had one of these computers back in 1984. I learned BASIC programming which set me up for what was to come. I owe my current level of computer and software literacy, especially with MS Excel, to the Pencil II computer. It did come with some very basic programmes and games, the BASIC programming for which, were so large, that the running speed was excruciatingly slow and they were virtually unusable.
I managed to write a few flying/bombing type games which ran a lot faster than those originally supplied. I also wrote a few display type programmes, one of which was for the local radio station. The Pencil II really was pretty good for that.
Where these cassette tapes are now, is anybody''s guess. Pleasant memories of a time when things were good.
