Re: Osborne 1 DD Upgrade

Hi John,

Basically, it's just a add-on board upgrade. That and the upgraded
system disks. Took me about 10 minutes to do the physical addition.
Software after that didn't take much longer. Boot with a DD disk and
sysgen a new boot disk.

If you're looking for a board, I have a couple of extra.

Hi All,
Does anyone know what the DD upgrade consists of?. Looking the the technical
manual it looks like the controller is DD capable and the /DDEN input signal
is connected to UC16 (PIA) although it is jumpered to GND (SD mode).

Thanks in advance
