Memory / Peripherals for Sharp PC-1600?

[Tinue]

I just wasted an entire afternoon, before I found this post.

Apparently loading code from a modern Mac to the Sharp PC-1600 simply does not work, except if one artificially waits after every line.

I then copied my small Java app onto a Raspberry Pi, and I could load a Basic program to the PC-1600 on the first try.

From PC-1600 to Mac works fine, on the other hand.
