			April.  Will connect to memory port initially,
			Mappiplexor later.
                           SYSTEM MEETING			2 Feb. 1976

Old Items

	Arms:		Both arms working!  Yellow arm was partly dismantled by
			an unknown someone.  There is evidence of possible
			sabotage using a piece of solder - TAG

	PDP-11 memory:  32k up.  More in a month or so - TAG

	Mappiplexor:	Artwork done, 3 weeks till PC cards manufactured.
			CHW will help wire. - JBR

	Librascope:	still down - TED, ELM

	Suppes Memory:	128k still up - ELM

	Monitor manual:	New manual just went to press - ME

	KL-10:		Presumably shipped January 30.  Power installation
			expected next week; delivery probable that week.
			XGP cable should be lengthened.

	Datamedias:	System mods to permit Datamedias and IMLACS to use E are
			being designed by ME.  Special characters will be typed
			on Datamedias in form ↑<mumble> and will be displayed
			as <bright mumble>.

	SAIL Manual:	Soon.  R. & A. Smith are bottleneck - LES

	IMLACS:		We have reaquired Dendral IMLAC (which we paid for in
			the first place), so we now have 2 broken (and 2 working).

	TV digitizer:	TED plans to slow down digitizer about 15%, giving
			slightly wider pixels.  No objections were expressed
			by Hand-eye users.

                           SYSTEM MEETING			2 March 1976

HARDWARE

	Arms:		Draft specification exists for new Gold Arm interface.
			Meeting needed to review.

	PDP-11 memory:  Slow progress; arm work has priority - TAG

	Mappiplexor:	Nearly all parts delivered.  Smoke test by end of
			March maybe - JBR.

	Librascope:	still down - TED, ELM.

	Suppes Memory:	no report (ELM).

	KL-10:		Letter from DEC says they will ship by March 27.
			They promise microcode package "very soon".
			Power is nearly in.  Air conditioning study needed →TED.

	Datamedias:	One here, rest expected by March 15, modems by end of
			month.  Home phone order being placed now.
			Possible add-on: extra ROM to give 256 character set,
			e.g. to include all of ours.  Possibility of getting
			additional SAIL keyboards from CMU.

 	IMLACS:		Former PDQ Imlac is apparently fixed;  will be installed
			in Phyllis Winkler's office in Polya, using new 1200 baud
			modem with dial-up line.  Library Imlac is broken.

	TV digitizer:	Slowed down a bit by TED;  seems to work reliably now.

	Surplus LPT:	We received a surplus line printer from Bell Labs.
			It is a close relative of ours, is twice as fast
			and not as old (but with burned-out clutches).
			TED will try to combine parts of the two to make
			a fast one with our character set.

	Ampex disk drive:  We have ordered an additional disk drive, using
			NSF Music money.  It will be a dual-port reconditioned
			unit.  Four additional disk packs also ordered.

	Humidifier:	Static electricity problems with hardware might be
			alleviated by humidifier for computer room.  JFR
			suggests that something suitable could be purchased
			from Sears in the $150 range.

OPERATIONS

	Malfunction handling:  REG complained about mishandling of LPT and
			XGP servicing and System malfunctions.  He or TED
			would like to be called about serious problems,
			whatever the hour.  "Reloads seldom fix parity errors."
			REG will review System and Spooler error messages
			to see that they express clearly what actions should be
			taken.

DOCUMENTATION

	Monitor manual:	New manual has been printed, should appear any moment.

	SAIL Manual:	Still awaiting Nancy Smith's Introduction - LES

	Font catalog:	Draft exists.  Font additions solicited.  Will go
			to press sometime around March 10 - LES

	Pub Manual:	We probably will break down and reprint it soon.
                           SYSTEM MEETING			4 April 1976

HARDWARE

	Arms:		Plans for new controller still as muddled as ever,
			but June deadline is still expected to be met.

	PDP-11 memory:  In limbo; cards back, ELM will take over.

	Mappiplexor:	Connector wiring & mods to devices are all that is left.

	Librascope:	Some bugs found; still down - ELM.

	Suppes Memory:	Remaining 128k await engineering changes.

	Datamedias:	Still only one here; no modems.

 	IMLACS:		Library IMLAC periodically down.
			Winkler IMLAC installation expected late April.

	Humidifier:	Decided to buy a cheap Sears unit.

	XGP:		Down last 4 days.  New fuser roller should appear
			tomorrow and hopefully will fix the problem.

	KL-10:		Arrived March 31, but we don't have a power plug of
			the right sex yet: expected April 7.
			Microcode and diagnostics software still not here.
			Need recommended spare parts list.
			Air conditioning study still needed →TED.

	MG-10 memory:	Running too hot; more fans to be installed - TED.

	Ampex disk:	Drive A intermittent.

	IBM channel:	JFR grumbled about channel lossage when transferring
			an odd number of words: last 4 bits of last word are
			zeroed.  Arguments for a replacement SA-10 channel
			were advanced.  It is possible that this particular
			problem could be fixed at time of Mappiplexor mods,
			though with more downtime needed.

	9-track tape:	JFR argued for aquisition of 9-track tape system.
			It is becoming increasingly difficult to find other
			installations with 7-track drives, let alone both
			7- and 9-track, as is needed to convert.

	Other possible buys:  New TTY scanner (e.g. 16 lines @ $6k from DEC),
			new swapping store, logic analizer ($4k).

	Task queue:	Temperature monitor installation (Heathkit).
			Merge BTL line printer and ours.
			Rebuild New Ampex memory interface.
			Build survivable clock.

SOFTWARE

	KL10 System:	Up by May? - REG

	E/Datamedias:	Another month to go - ME.

	File cruncher:	Being written by REM, up soon.  Typically reduces file
			sizes by 50%.  Also packs multiple small files in a
			larger one, thus saving disk space.

	MACLISP:	Its up: most efficient LISP compiler in captivity,
			has programmable reader and other features.
			See MACLSP.DM[UP,DOC] - RPG.

	New font editor: TVR is designing a font editor based on "outlines".
			Will produce fonts for use both by XGP and for microfilm
			output.  He will also make a XGP file → microfilm
			translator.

	Task queue:	Overall plan for integrating file system, crunching, and
			    archiving.
			File archiving to Datacomputer.
			Vectored gripes.
			Super-Pub.

DOCUMENTATION

	SAIL Manual:	Nancy Smith's Introduction exists, but it is immense
			and wordy.  We may print just the manual after all - LES.

	Font catalog:	A number of new fonts have been discovered and are being
			incorporated.  Should go to press this month - LES.

	Task queue:	We probably will break down and reprint the PUB manual soon.
