Still using AMON on the 2SIOJP.
The SD switch is in the closed position (0). If I open it, the monitor won't boot at all.
My 2SIOJP came with the 4K EPROM so I have RAM set to end at EF00. I set that with the ROM switches on FDC+ board set to EF00 with the ROM disabled and the RAM enabled and set to start at 0000.
I was playing around with some to the DIP settings and now things seems to be working better. Here is how I have the 2SIOJP set (using O for open and C for closed)
- Code: Select all
8 7 6 5 4 3 2 1
SW2 O O C C C O C C
SW3 O C C O O O O O
Maybe there was a dirty dip switch causing me some trouble.
And the FDC+ set like this (using D for towards bottom of board and U for towards top of board):
- Code: Select all
8 7 6 5 4 3 2 1
RAM D D D D D D D D
ROM D U U U D D D D
I'd like to try booting CP/M from the serial server. Any suggestions on how I should set things?
