When it comes to documenting the info needed for hacks, there's no such thing as off topic
in this forum!
This was my turf back in the day when we had individual moderators for forums, Peripherals was my first assignment from the "kids" when they invited me to join the mod squad and, for some unknown reason, my name popped up for the Hacks forum as well.
When dougg3 needed the ASC info in GttMFH2E
for his IIci ROM hack . . .
. . . it appeared on his virtual doorstop and he purchases GttMFH2E!
Nailing down what info is in which edition of these books is important. I'll assume that the first edition of AFHR
covered the 128, possibly the 512k.
I'll guess that the 2nd edition covered the Pre-ADB SCSI Macs, likely assuming that repeating the earlier info was redundant.
The first edition of GttMFH
was likely limited to the additional info for the ADB Platinum Plus along with the unprecedented expansion capabilities of the SE's PDS and '020, NuBus Mac II.
GttMf2E was likely added to cover the 68030 Machines and the Portable up thru the IIsi.
Same for "Designing Cards & Drivers for the MFH" editions 1 thru 3, which blatantly refers to "an understanding of the info in GttMFH2E.
I doubt Apple wasted much paper or effort on repetitive information.
BTW, I also have the 1998 LaserWriter - LaserWriter IINTX, LaserWriter Reference
. . .
. . . if anyone is interested in hacking these beasts.
One day the 68kMLA will have them ALL!!!!!!
