Hey Guys,

So I started messing it with again last night with the new memory map and I think I have some broken traces on the VFB-1000 pcb, so I need to take it back out and trace all the sockets that I replaced, I have confirmed that the ram on the ZPU-1000 and BSC-1000 are good, so that is a plus.

If battery damaged it could be lacking the power to power up the ram.

And yeah, wrong address space :)

Hey Guys,

I'm bound and determined to get my Berzerk working again. Currently I
have it working to the point that the game will boot however the game
will freeze randomly. List of things I have done:

New sockets on the ZPU-1000 with new EPROMs and Z80 processor New ram
sockets on the VFB-1000 and I have 4164 ram and 4116 ram that I'm
looking into putting onto the VFB-1000.

The BSC-1000 color board is fine, and the cleanest board I have on
the machine.

When I go to do the short ram check on my Berzerk board set, the
0-7FF fails, however the second one, 1000-17FF if I remember passes
correctly.
If anyone knows any tips or tricks with using the Fluke 9010a with a
Berzerk board set I would appreciate it.

Thanks
Grant
