Datacorder
The tape/cassette reader/writer.
Slow and painfully, yet it makes a funny "Matrix like" sound on old 464...
Spanish Scene still produce games on this media...maybe the Nostalgia or pure masochism.
A problem encountered with this format lies when the software have to take control of the Datacorder (to stop or play...)
As no CD reader nor MP3 reader were designed on this purpose, you have to do it manually.
Also a problem lies when a software needs frequent Data reading/Writing.
Oddly, the 6128+ do not have Tape connection at all.
But as the Mainboard is the same one the 464+ and the 6128+ you can easily fix this if you cannibalize a 464+ to improve your 6128+.
Just pierce a hole in the plastic, put a Jack connector and use it for small games with any mp3 walkman.
More complex games or softwares should better use a Disk-like system.
