uBee512 Sanity Checking?

[ChickenMan]

Arr the ubee512 ver 6.0 for MAC was not produced by the original author of ubee512 and appears your missing the HDD entry in the roms.alias file -

#===============================================================================
# Microbee HDD boot ROM
#
# c45452cb2981223fda043b99d468cacd HD18.ROM
#
# This S60HDD18.ROM ROM is a 3rd party combination of the BN60 and HD18 boot
# ROMs with some changes to select the WD1002-5 or Coreboard WD2793
# controller using additional port located at 0x58.

HD18.ROM md5=c45452cb2981223fda043b99d468cacd
;S60HDD18.ROM md5=d25c81901b5a4cce79239ef6dfb1469b

But I suspect your --model=p128k --rom1=HD18.ROM is doing the same thing.
