Z80 CPU board and Serial I/O board setup issue

["Mark G. Thomas" <Ma...@Misty.com>]

Hi,

My setup is as follows:

- Z80 CPU board version 2
- Serial I/O board version 2
- Compupro RAM-17 64K static RAM board
- Compupro S-100 motherboard

I burned the version 5.04 monitor into the lower half of a 27C64, 
and have P39 jumpered 1-2.

I see D5, D7, and D8 lit on the CPU board, and see data on 
the S100 data and I/O lines with a scope, but no LEDs at all 
lit on the Serial I/O card, and no activity on serial port A.

Questions:

- I have a Z8530, not a Z85C30. Does it matter?

- I used the MASTER.HEX file from Master (5.04).zip  I'd welcome
a full-sized HEX or BIN file with the code appropriately duplicated.
Will 5.04 work with this setup above?

- I didn't see K3 on the CPU board mentioned on the s100computers.com page, 
but 1-2 seems to be what's necessary for me to get D5 (ROM SEL) lit.

I can post jumpers info or pictures if that's the next step. It's definitely
a chicken-egg situation when starting from nothing.

Mark
