A few more corrections:

						Everything I've seen so far

						the video clock divided by 2.

		Internally expandable to
		1MB with 256K chips, to
		4MB with 1MB chips
		both expansions use a
		memory daughter board;
		Memory map allows max of
		15 Meg

		The DMA port supports up to
		8 devices; this is also where
		the CD/ROM will plug in

		Custom timing control chips
		that allow cpu to run at 8MHZ,
		and to manage memory accesses
		so that video refresh and cpu
		memory supposedly never interfer

		Single or double sided drives
		available; single is 360K,
		double is 720K; with special
		cable standard 5.25" drives can
		be attached; disk storage format
		is IBM compatible

		Disks are data compatible.
		There are rumors of a software
		IBM emulator by the end of the
		year.

		Has been available worldwide
		for a few months; in the US
		for almost two months.  I've
		seen news reports that close
		to 50,000 have been sold so
		far worldwide.

		Some packages available now
		in US.  More are supposedly
		available in England according
		to news reports.
