More fun with Freed Z80

[Steven Hirsch <snhirsch@gmail.com>]

All,

I received my 512k SRAM chips yesterday and upgraded the board.   It now 
provides a 391k on-board ramdisk when the RAMDISK.DVR is genned into the system.

I can also confirm that my ProPartition utility and driver works fine. I was 
able to create a quick 4MB partition on my CFFA and am using that as the A: 
disk currently (you cannot boot directly from the hard disk with this driver. 
That will have to wait until I can blow the dust off the modified PCPI 
operating system that boots from ProDOS).

I have the USB interface and 20Mhz. crystal already.  The 20Mhz. Z80 and PLDs 
should be here Monday.
