Is it possible to implement a system connection on an ATM? — ZXNet «hardware.zx»

From Evgeny Muchkin To All 13 December 2006

Hello, SfS Of course it is possible, and even necessary! How to do this is described in detail in Spectrum Expert 2 - http://trd.speccy.cz/press/sp_exper/SP_EXP2.ZIP In general, it is not necessary to assemble the ZXBUS expander circuit to begin with, but how get from any Speccy all the ZXBUS bus signals described there.

Hello, All Is it possible to implement a system connector on ATM? If yes, by what standard? better? I mean a connector with a full bus of address, data, control signals etc. Not everything can be connected normally as input/output ports.

Hello, SfS Of course ZX-BUS. A pair of rulers according to the Scorpio-KAI standard.

Which system connector do you recommend? They seem to be on several specs. By the way. I sincerely hope that the ATM-3 will still have a system connector implemented directly on the board. Or not ?
