I just pulled a big mechanical AT-style out of storage - an with a 5 pin mini din plug.

Its a beast, with 24 programmable keys.

8/ I put the tape recorder back together enough for it be safe until I got a proper workspace cleared off, and on a whim tried a tape in it. It's working again, but now it's got a sort of buzzy, noisy sound to it. It's a pretty simple design, and whoever assembled the thing did so in such a messy way that I wonder if I should just replace/resolder everything.

(sort of) (maybe?)

7/ I'm not seeing anything obviously wrong. I sort of expected to open this up and see that a cap had popped or was leaking (the yellow crust on a couple of the caps is dead adhesive from some decades old tape I peeled off) or something else that'd be a giveaway. Guess it's time to get out the multimeter.

6/ Four easily accessible phillips screws and you're right there at the audio i/o board, belts and speaker. What a convenient, simple design! From the sounds of the screws coming loose, I thought I must be the first to open the shell since it left manufacturing, but there appear to be bodges on the audio circuitry and witness marks on the screws that secure it to the cassette player mechanism.

3/ The recording seems relatively clean, so my first thought was that this was recorded from a computer directly - perhaps something like one of the old Atari 8-bit machines, that would play an audio recording while reading the program data? I am pretty sure though that I heard a chair scoot on the second third loop of the song. So now I'm curious if anyone recognizes the tune?

2/ After 5 mins or so I started using the Fast Forward to jump around and see if there was anything recorded, with no hints of anything. So I let it spool up all the way around the other reel, and tried the other side. There was an abrupt sort of noise preceding a recording of a simple song being played on repeat, which to me sounds like maybe MIDI music.

1/Got a cassette tape recorder from the thrift store today. I didn't notice until I got it home it had a cassette in it, entirely spooled to side B. After I pulled the batteries out (labeled 'Best if installed by Jan 1997') I plugged in a figure-8 cable and hit play. Surprisingly, the tape reels started spinning and the speaker output the kind of quiet white noise you'd expect from a blank tape.

I ended up staying up way past my bedtime fixing old macs. This is a 512 @billgoats rescued from an arctic landfill and mailed to me a couple decades ago. After fixing up its floppy drives, It died shortly after taking this photo, probably bad solder joints on the analog board. One of Linotypes that it shares a room with is dead from similar ailments.
