Newbrain Laptop
23/3/2010
Hi to all,
I am currently developing a z80 computer which i hope (when finished) to be a Newbrain AD. It will run most of the Newbrain's AD software. The final project will be portable using a LI-ION battery, so it will be like a laptop.

The CPLD programmer and my CPLD adapter are working ok so i can program and test the CPLDs.
For a low cost XILINX parallel Cable III See this: http://viewitem.eim.ebay.gr/Xilinx_Parallel_download_cable_III_support_JTAG/220579919598/item
Also i made a PCB for Z80 and one for the memory chips (I had to make two in order to avoid a two side PCB) and i am currently checking these two.
Next week i ll have to return to work so i ll have less time available so progress will be slower.
