Got my Zeta SBC v1.1 running at 2Mhz!

Hi, I finally got around to getting something built!  One of my friends is a hardware hacker so I went over to his house and we built up the Zeta SBC v1.1 board I've had forever.  My friend did all the soldering though, so it probably doesn't count for me building something, so next I'll do all the soldering on the v1.2 board I have laying around.

We got it working with an old Z80 chip he had laying around, some strange white one, not the usual black color.  Says "Zilog Z80 CPU, DALLAS, 7623" on it.  I looked it up and it runs at 2.5Mhz, so we used a 2Mhz crystal to test it out.  See the photos in the link below. Works fine, we were able to boot from rom and run microsoft basic etc.

Next we need to update the firmware, since I bought the chips from Sergey 2 years ago, and I read that the firmware has been improved since then.  And get a faster cpu so I can use floppy drives.  And get a ParPortProp board.
