Hello,
I will get a brown C64 today, which will complete my set of 4xcores, 4x6581 and 4x8580.
I will use the optimized PSU set-up, and some things are not yet clear for me:
- the 7805 are dropped because the PSU provides stable 5V
- there is a 7809 to stabilize the 9VAC output, and combined with the 5VAC output, it provides 5VDC and 14VDC
- the "Optimized PSU" document don't mention the MBHP_SID 78xx : do I need to put one 78xx by MBHP_SID, or can I use one 7809 for the 8580, then link the power to the three others, and the same for the 7812, or is it better to have all MBHP_SID their own 78xx to avoid ground loops?
Kind regards,
Xavier.
