We desperately need help on the following topics, related to a Systime 1000
running RSTS 4.0A ( for those outside the UK unfamiliar with Systime they
are an English company, who among other things, have for some years OEM'd DEC
products - the 1000 is a PDP11 box).

The machine was rescued by us from the great machine room in the sky when
a comercial site was scrapping it, we now have it up and running but have
very little documentation. In particular information on the following would
be most appreciated.

	- Extended memory paging in this machine.
		we are at present running on the minimal 32Kword configuration
		, we have extra memory cards but the test program XMEMC claims
		it cannot find the 'extended paging register' and claims to
		be looking for it at an address which the DEC hardware handbooks
		for the unibus claim is reserved for the AD01 ADC.
		I cannot find any reference in any DEC documentation to an
		extended paging register, only the memory management registers.
		the address it claims to be looking for this register at is
		776772.

	- Systime serial cards.
		we also have a four channel serial card which would like to
		add, but cannot find any documentation about switch settings
		etc. This is a Systime card and as far as I can see is totally
		different from any DEC cards.
		The systime part number is 30-0120

	- Disk drives.
		we have a pair of Ampex front loading 12Meg cartridge drives
		again no documentation.

	- System software.
		The system packs we actually aquired with the machine, were
		simply the sites working system packs, with everything but
		the utilities they actually used deleted. We certainly don't
		have distribution packs. copies of programs like MACRO11 and
		LINK which are standard distribution, certainly with later
		versions of RSTS, were not on our system packs.

(DEC, RSTS, MACRO11, Ampex and Systime are probably all trademarks.)

Thanks in advance ...
