Here are several questions I've been sitting on for a while. As
background information, I have a 512K (upgraded from 128K a la Dr. Dobbs)
Mac with the "ROM-Disk" upgrade (an "Enhanced" 512k?).

- Does anyone on the net have a Levco SCSI port installed on an
  "Enhanced" 512K Mac? Does it require the purchase of a "Monster Mac"
  board first? Is it REALLY the same as the Mac+ SCSI port?

- About "Monster Mac" boards - do they use plain old 256Kx1 DRAMs in
  16 pin DIPs? I'd like to be able to get a meg from them now and
  upgrade to 2meg later.

- Where can I get documentation on the built-in debugger in the new ROMs?
  I get a window when I press interrupt, but no response to ANYTHING
  I type in.

- What resources in the 3.1.1 system file can I safely remove with
  RESEDIT? Since 3.1.1 worked on my 512K Mac BEFORE I got the new
  ROMs, I assume that there MUST be stuff that is duplicated in the
  system file, and I'd like to reclaim the space.

Thanks in advance and all that - please mail responses to:
