The language disk is just an old-fashioned Basic, in this case First Basic. I’m not sure I’ll be able to go into much depth with this one when it’s been decades and I don’t particularly want to learn a shit basic! As you can see, I did what I needed to do.
This was what we had instead of Microsoft Office. A text editor which could do bold, italic and underline, but no different fonts. A spreadsheet that I haven’t yet managed to figure out how to do a formula on. A calendar which as far as I can tell just lets you type some text in each date box.
Music maker is a surprisingly charming little tool to create music using either the sound chip or a connected MIDI device. It can handle rather more than you might expect and while I don’t remember playing with it much as a kid I can imagine it helped a few people into the world of music. The biggest headaches I found were mostly in the drum editor where you can’t have any polyphony and clicking one cell tends to trigger other cells.
