The second batch of 10 bus expanders arrived. I have 5 units already compromised on Spain, so it left another 5 bus expanders and 5 M-Slots to sell.

This second batch has some modifications proposed by Zozo:

-A 9 pin header to put pull-ups to the Z80 Data bus.

-A point on every slot to feed +9v or ground on 33A/B pins for classic extension boards.

I also have put a little hole on every corner just in case the PCB needs to be screwed into a box.

The price is still the same, 15 Euro the bus expander and 10 Euro the M-Slot (+postage). Due to the long distances, better I will provide the units mounted and tested.

Somebody asked me on August about a Bus expander, but I don't remember who was.

I still have some mounted units of both the bus Expanders and the M-Slot, ready to send.

More batches will be ordered on demand.

If it stays, I would, however, I'll take the set (both units).
I do not have time to do it myself.

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.

Today I have received the SIL to EDGE cards and I have mounted some of them:

21902-0

It will connect to the rear of the Bus expander as this:

21904-1

It has all the Enterprise Expansion Bus signals. The cost of the adapter is 2 Euro+postage.

Yes, the Microteam is very versatile, complete and has its own 7805 regulator. Only its big size is a problem.

With the EDGE terminal it also can be easily connected horizontally at the rear of the Bus expander.

This is the final aspect of the fixed M-slot:

22300-0


22302-1


22304-2


It has some errors, but soon I will order a batch.
