....yes, maybe, I am not a hardware specialist but MB02+ connects of course to Z80 processor. The problem is that it has DMA chip. This chip must be close to Z80 bus in order to work OK. that is why we must have MB02+ connected directly on a bus, we cannot use cable
But MB02+ has a lot of additional features. It was designed more then 10 years ago, but it is still very good. It has:
RTC chip, parallel 8255 chip, kempston joystick port, IDE interface, 512KB SRAM backuped with battery, nmi button, FDD.
The price now is about 190 USD. And it looks like this (my old web page, in Czech, but you will see photos):

In Czech Republic, we mostly use original ZX Spectrums, mainly 128kb.
In case, somebody would be interested, I could try and get MB02+ for him.

Many thanks Antipod, but I am also short of time and if I want do something good on speccy, it will be my nmi menu, not this copy tool. This is my opinion at the moment, but who knows, the situation can change. Do you have some photos of your GUIs?

MB02 + too different from the ex-USSR designs, it is unnecessarily cumbersome. This prevents the promotion of MB02+ in the ex-USSR.
