BBC Micro to Desktop Cable

Although Eazylink2 has primarily been designed to be used with the Z88, it supports the 'built-in' Imp/Exp protocol that the Z88 uses. BBC Link also used this protocol which means in theory, file transfers should be possible between the BBC Micro and the Desktop without a Z88 being in sight.

 

See Z88 BBC Link for more details

Note
titleThis has not been proved yet

The BBC Micro to Desktop connection will only work with Imp/Exp. All the other modes described in this document only apply to the Z88. USB to Serial Adapters should work but as yet none of this has been proven. The author does not have a BBC Micro, so feedback would be appreciated.

Z88 to PC Cable with Serial USB Adapter

There are two types of PC to Z88 Cables available that can be used on all the Desktop computer  platforms.

  1. Z88 9 way male to 9 way female (Later PC Standard)
  2. Z88 9 way male to 25 way female (IBM PC standard)

...

Warning
titleWARNING - This is not a standard cable

Please DO NOT be tempted to rush out and get a standard 9 way male to female cable. They WILL NOT WORK. There are two reasons for this.

  1. The Z88 connector end has no screws in them. If they are there, they will prevent the plug from being inserted into the Z88.
  2. The wiring of the pins is different to the standard connections as the Z88 came out before the standard for the 9 way connection was established.

The correct cable (still sealed in a bag from Cambridge Computers) is available from Rakewell Ltd.

...

If you use the Z88 9 way male to 25 way female cable, you will need to use a 25 to 9 way adapter to use the 9 pin plug on the modern Desktops or USB Adapters.. Please ensure that all the 9 way pins are connected. Some adapters only connect 3 of the pins, sometimes the only way to tell is to buy one and test the connections with a meter before use.
