cbm8032 crashing at end of tape load...

From: didier derny <*didier_at_aida.org*> Date: Fri, 4 Nov 2016 21:46:20 +0100 Message-ID: <44ff10fc-9c90-c076-eb04-1d326df6cda9@aida.org> · didier_at_aida.org

now the cbm8032 is powered with 12v DC with 2 diodes added on the 
circuit to drop the 12v to about 10.8v  (9.3v on unregulated connector)
when I check the 6v  on the tape connector it is at about 6.05v seems 
correct

when I try to save a program everything looks ok
when I try to load a program seems ok to the ready but no cursor ?
any idea ?

I may have a clue... the cursor blinking seems irregular  I guess a 
problem with the irq ?
any idea how the irq is generated on the 8032 ?  6522 ?

thanks
