Hello All,
After completing my Zeta SBC, I've decided to contribute back to the group
by having PCBs made and building/testing the Zeta-to-ECB connection board
that Sergey was working on earlier in the year, but hasn't been tested yet.
This will allow Zeta builders to extend their systems onto the ECB bus and
take advantage of all the other N8VEM cards.
My plan is to build the 8-slot ECB Backplane, a Bus Monitor card, and a
Color VDU card. This will allow me to test the following configurations:
-Zeta on its own with serial terminal (currently running)
-Zeta w/ParPortPortProp
-Zeta w/ColorVDU for display/keyboard support
-Zeta w/ColorVDU for display/keyboard and ParPortProp for the SD Storage
After that I'll probably add a DiskIO V3 board which would allow me to test:
-Zeta w/ColorVDU for display/keyboard and DiskIO V3
I'd appreciate if everyone could take a look at these schematics and board
layout from Sergey and give any comments over the next few days. I'm still
coming up to speed on a lot of the electronics design aspects of this (as a
mechanical engineer I know just enough about this stuff to make me
dangerous - although I am trying hard to understand this board and the ECB
bus, and I think I have a good handle on the Z80 itself and the design of
the Zeta) so I don't think my own review will be very useful right now.
I am planning on having about 5 prototype boards made, so if someone else
has both a Zeta and an ECB system and wants to participate in the testing,
I'll make those boards available to the group when they arrive.
