Re: Apple IIBF (IIGS Prototype?)

["Jplcsch" <jplcsch@wanadoo.fr>]

On  mine i've put an High Speed SCSI and a HD with 4 partitions under
Prodos. All is OK
It's impossible to use GS/OS because it's not a ROM1
My id for the proto is :
    VEGAS PVT
    S/N 36
    May 86
The contro Panel is OK and the boot perfect.
Pleasure to read you
