They're the same thing. The 4 is just a 2 with double sided disk drives.

There's later 2/83 ad 4/83 types with the CPU running at 5MHz rather than 2.5MHz.

I've been doing my homework. :-)

A Z80 running at 5Mhz is a thing of beauty 😁

Especially without the need for wait states due to screen access.

Anyway, this evening I've been getting on with some model railway stuff. I've been working on the first bit of station platform: foam board core with 3D printed walls and coping stones. Eventually the "asphalt" will be simulated using tile grout painted grey.


The coping stones aren't yet stuck down.

Let us know of your progress.

Of which one? The Kaypro or the model railway? :-)

The model railway for me.

Hehe. OK.

This is what it looked like when I'd (almost) finished laying the track last July.

Hi Stephen, Its Z8430AB1 I have, so sorry, can't help you on this occasion.

No problem. :-)

More model railway station platform building tonight.

Popped out to B&Q to get some charcoal coloured tile grout, which will become the asphalt, and then stuck the coping stones down.

Designed and printed some central concrete drains. Sprayed a number of them up so I can stick those down tomorrow night. I can then try out the grout.
