A little add-on has been designed by my friend Wilco. It is a clone of the Enterprise external connector that would be connected at the rear connector of the bus expander.
The components are only a narrow PCB and a male SIL 90 degrees connector, so it will be very cheap and easy to made.
It will allow to plug there your trusty EXDOS direct-connection interface, like the compact clone from Pear, the Microteam or the Spanish EXDOS clones.
Not for the original or Hungarian EXDOS(through Bridgeboard), logically, these can be plugged on one of the three slots(both as SIL or as EDGE, ask me more about this if you are interested).
The benefit is that you will be able to expand your Enterprise without losing the use of your old floppy interface.
It will take only a month to finish this adapter, the usual time from order the PCBs, to receive, mount and finish them.
From now on I will sell it in a bundle with the bus expander as a feature. I can also sell it separately to the users that already own the bus expander, almost all Hungarians, so better if I send only a pack of them to Zozo's.
