Okay I think I'm starting to figure this out a bit. Beginning with basics, I cleaned up the contacts on all the SS50 pins. The system seems to power up more reliably now. Next, I poked around in the monitor to figure out exactly which addresses the modified MP-M board was dealing with. Since

It seems to me that one possible solution would be to whip up a PLL in a CPLD or FPGA to generate 12 sector timing from a 16 sector pack or vice versa. On Tue, Sep 6, 2016 at 8:58 AM, wrote: > I'd like to trade two media. > > > Am 06.09.2016 um 17:48 schrieb Noel Chiappa : > > > > So I have a f

Odd memory error in PDP-11/04
