This is one of the original Commodore Datasette drives I got with the 4032 long ago.
I love the plaited cables on these. I don't know if they were supplied like that, as I haven't seen any others like these. They appear to be three pieces of speaker cable plaited together.
Also unused for 20 years, all these needed was a general clean up, a new belt and a head clean and they worked fine.
The other was the same, just a different plug. The DYMO labels are original by the way.
The same design was used with early VIC20s, black and grey replaced by white and gold, and the addition of a tape counter (like the imperial Daleks in Remembrance of the Daleks, apart from the tape counter that is)
The white seems to sit better with the Pet, and the tape counter is useful. These also seem a lot more solid that the later 1530 Datassettes (or C2N, they seem to use the name interchangeably).
During the testing, I've been using a tape with space invaders on it. It is a good game, and has sound and reasonable graphics. But mainly because last time I was working on a Pet, I tried various methods to transfer from a PC to tape, and this was the only one that transferred successfully.
