Title: Cant get back to OS after Formating
Post by: retro_collector on 17:38, 01 October 19
I just got my 6128 plus. I boot CPM +, then tell it to format drive B as System disk or data disk, when it is finished it says REMOVE BOTH DISKS PRESS ANY KEY TO CONTINUE,


No matter what key I press it just keeps saying [size=78%]REMOVE BOTH DISKS PRESS ANY KEY TO CONTINUE[/size]
[/size]
[/size][size=78%]Thanks for the help[/size]

Which Hardware Extension have you plugged in? Did you boot CPM from ROMs or DISC?

I have an external 3.5" drive with cable going from 6128 + Centronics to Floppy drive

Maybe the handling of the ready signal of the 3.5" external drive?

the cable has ABBA switch and head change for Gotek so I don't know how I can fix it

The ready signal has to be fixed by modifying a couple of bridges on the disk drive's pcb, as far as I remember.

You really should have correct Ready signals for CP/M+, SymbOS and FutureOS. Advanced software depends on that.  :)

Yup.  I found the mod. Also requires a 1k resistor :). I will do the mod and report back
