the processor is an HD63C09EC, so normaly no oscillator build in
is SW3 correct, on "C"

Greetings cream51,
The jumpers look correct but the dip and rotary switches are not right.
The dip settings are the inverse of what they should be. switch 7 & 8 should be off (1) 1 to 6 should be on (0) to set the I/o address to 0xC000
The rotary switch should be set to 0 for Assist09 or 1 for Basic09.
Do you have any tools to help diagnose your problems? I find a logic probe indispensable for initial testing.
htht, Best regards, David.
Edit, this is my second attempt to reply. The first one never made it to the forum for some reason when I posted it.

Sorry, I somehow missed this message.

But, it looks like David has you covered. Thanks David!

I'll just add one more thing: The 'ROM WE' header should have a jumper. Normally you would have this in the 'RO' (Read Only) position. This provides a pull-up on the ROM program /write pin.
