FPGA Amiga 1000 mode may be needed..

At gregdonner.org/workbench/wb_10.html I found that there is a pre v1.0 Kickstart that is required for some very early demos:

# Mark Knibbs also noted that years ago a catalog disk was received from an American company called "Chiron Conceptions Public Domain." Listed in this catalog were some very early Amiga demos, used when the Amiga was launched in 1985. They require a pre-1.0 Kickstart, version 27.3, to work. Below is the listing from the PD catalog:

VERSION 27.5 DEMO DISKS

CC-001 --VERSION 27.5 KICKSTART

Pre-release version of the Amiga Kickstart. Needed for some disks.
(Note: Will not work on the Amiga 500 or 2000)

(Mark Knibbs - banana(a)websSPAMSUCKShuttle.chKILLSPAM)

Thus to run these demos (and other early software) this early kickstart is needed which in turn require full Amiga 1000 FPGA implementation.

Or, alternately, an Amiga 1000 ;P
