    Some weeks ago, I pulled out my Heathkit H19 monitor to connect to my H8, 
and the H19 promptly blew a fuse (and other nasty things). I finally got the 
last parts in today to fix it, and the H8 is up and running CP/M 2.2.04 from a 
Z87 dual-drive unit.


    The H8 only has two boards installed: the H17 hard-sectored floppy 
controller, and a Z80 board from a recent Norberto Collado design. The Z80 
board has 64KB of RAM, two serial ports and a real-time clock. Here's the 


    Norberto also has a new storage controller design, to replace the H37 
(soft-sector), H17 (hard-sector) and H67 (hard drive) controllers, plus a USB 
interface. I have the PCBs, and am waiting for some final testing before 
ordering parts.
