 ---------------
 The best build options for Mini vMac are: `-br 37 -m Classic -lt -speed z -as 0 -chr 0`. Note that this requires the new (as of mid-2020) version of Mini vMac, with Rob Mitchelmore's clever LocalTalk-over-UDP tunneling.
 
-The xo-rom-enable-netboot.py script can edit xo.rom (Macintosh Classic) to force-enable the netBOOT driver (essentially by editing PRAM). (It requires you to build vasm with a quick `make CPU=m68k SYNTAX=std`.) This enables quick iteration:
-
-	cp xo.rom edit.rom && ./xo-rom-enable-netboot.py edit.rom&& Mini\ vMac\ Classic.app/Co*/Ma*/* edit.rom
-
-Running NetBoot.py simultaneously now shows the netBOOT driver sending DDP packets.
-
-(Some progress that I didn't bother writing about)
-
-It works! (Albeit with a heavily patched Classic ROM.)
+Run `make testchain` to boot an emulated Classic from a Python server.
