I am selling my 7300.  It has the following features:

	* AT&T 7300 UNIX PC
		- Motorola 68010 processor
		- green monitor
		- keyboard
		- mouse (doesn't completely work - see below)
		- on board 1200 bps modem
		- parallel printer port
		- built-in serial port
		- EIA serial port card (two ports, for a total of three)
		- standard low-density floppy drive		
		- 67 (80) Megabyte hard disk drive (Seagate ST4096)
		- 1 Megabyte total memory
		- 2 3B1 power supplies
		- 3B1 bump-top case

	* 7300 motherboard w/512k RAM.  I don't know what version of
	  the motherboard it is, but it doesn't have the annoying
	  daughter card, anyway.  The real time clock battery is dead.
	  I usually keep the system running 24 hours a day, powering
	  down only for thunderstorms and such, so it seemed less of a
	  pain to re-set the time at each infrequent boot than to
	  actually replace the battery.

	* The monitor had the infamous C411 capacitor go bad.  This
	  has been replaced, and the guy who replaced it also made
	  some adjustments to the monitor.  The picture looks great
	  now, better than it ever looked before!

	* 512K memory expansion card.

	* Two port serial card.

	* The ST-4096 disk drive is mounted inside the case.  I
	  replaced the original 7300 power supply with a 3B1 power
	  supply, and replaced the original slant case with the 3B1
	  bump-top case so the drive would fit inside.  However, the
	  hard drive drew too much power (I got loads of HD ERR's in
	  in the log file), so I have a second 3B1 power supply
	  mounted externally in a makeshift box that feeds power in to
	  the hard disk only.  One of the two original internal fans
	  has been moved out to this box also.

	* The ST4096 disk is 1024 cyls, 9 heads.  As the system
	  stands, it can only access 8 heads.  About 8 Megs more of
	  hard disk space could be gained by installing the P5.1
	  modification (instructions available on the net) allowing
	  access to the 9th head.

	* The mouse has stopped tracking vertically.  For all I know,
	  it could just be dirty as I hardly ever used the mouse with
	  this system and thus didn't care much about making it work
	  again. 

	* The system runs fine as it stands.  With 1 meg of memory,
	  the system does swap occasionally with one user, but I don't
	  find it unbearable.  If the purchaser wishes to increase the
	  memory size, there are two or three options (putting 2M on
	  the motherboard, changing the 512K card to 2M; I think you
	  could also populate the EIA card with 1.5M).  I am running
	  the 3.51m kernel with no problems.

I am selling this system because I find that I just don't use it.  I
have left it unplugged since two or three thunderstorms ago.  The
system is here in the Minneapolis area; if you want to check it out
(or have a friend check it out) give me a call.

Asking price is $400 + shipping.  If you think that's too high, let's
talk about it.  I can include the original slant case top if you want
it.  If you hurry, I'll even throw in an old 8 pin dot matrix printer
(Legend 1080) and cable if you want it :-).
