You're right, sorry; corrected my post!

From APIN-OFFICE.TEXT:

--- Code: ---{constants used to check the value returned by the Mach_Info call
(the I/O board part of the record)}

IOlisa       = 0;    { Old I/O board (lisa) w/Twiggys }
IOpepsi      = 1;    { New I/O board (pepsi) w/Sonys and Widget }
IOlisaLite   = 2;    { Old I/O board (lisa) w/Sonys }
IOpepsiLite  = 3;    { New I/O board (pepsi) w/Sonys, no Widget }

--- End code ---

And there we have it. I didn't know a Widgetless 2/10 was called a PespiLite. Better than Diet Pepsi I suppose?

Reconnected with Ron this weekend.
Here is a talk where he talks about AppleNet
https://www.youtube.com/watch?v=pFxNwUhL3Wg

AppleNet is between 27:15 to 29:35 if anyone's in a hurry, but he goes on to talk about LocalTalk and continues from there through the G5 and beyond. Thanks for the link!

Here's another tidbit I saw in source-PROFILE.TEXT

(*Drive types*)
T_Profile = 0;
T_Seagate = 1;
T_Widget  = 2;

if (discsize <= 9728) or (discsize > 30000)
then drivetype:= T_Profile (* set drivetype to profile *)
else
if drivetype <> 0 then
begin (*widget*)
  remap_interleave := false;
  drivetype:=T_Widget;
  rvrs_hdr:=20; (*headers are at end of sector*)
end
else
begin (*Seagate*)
  drivetype:=T_Seagate;(*10mb seagate*)

(I cut some lines out of this code). So if the disk is exactly 5mb, or over 15mb use the Profile driver. If it's a Widget use that driver, otherwise use the 10MB Seagate (10mb profile??) driver.
