New Boards On The Way

Finally, after being involved in non-electronic projects for a while, I’ve been able to finalise the new ZAViouR board v1.02 and the 7400 based I/O expansion board v1.00. Both have been sent to my favourite fabrication house, Hackvana and I await the acceptance e-mail.

Meanwhile, I’ve also started on an 8255 based I/O board, a Zilog Z80 PIO based I/O board and of course, the Backplane board. After the ZAViouR and 7400 I/O boards have been tested, I’ll get the backplane fabricated.






I’ve arranged the expansion connectors so that the backplane will replace the I/O board and the I/O board and up to three others may be plugged into the backplane. The backplane has now an optional daisy-chain connector so that more than one can be connected.

The I/O board and Backplane required a specially mirrored 40-pin IDC connector which I created as a custom component in Eagle. There is no difference in the physical connector, just how the connections are utilised on the PCBs.

Once tested, all the design files will be available on their own page which I will add to the site.
