Systems Archive, Part 1 Sun Sparc LX

Posted in Uncategorized on 21/03/2010 by Undersys

I’ve been meaning to do this for a while…

I’ve got a lot of older hardware. I want to get images of them and details of them before they stop working or parts are hard to find/ repair.

I am going to start off with the first computer i personally owned, and I still like it.
It’s the Sun Sparc LX. I picked up mine with an external HDD and CD-Rom. Also came with a 21″ CRT(1600 x 1280)
The LX comes with a 50mhz 32bit Micro Sparc, an on-board CG6 and audio,Ethernet(10baseT),ISDN,AUI.
You can net boot them over AUI or Ethernet 10baseT, they can even run disk-less as a X server.
Supports up to 96mb of ram, mine has 64mb.
The LX also supports a “vsimm” its add-on video memory to support higher resolutions, mine came with a 1mb vsimm.
The LX also had two Sbus slots running at 25mhz.
Included in the top half of the case was a 50pin SCSI HDD and a floppy drive.
Given the age of the LX(Aug 1993) it really did shit all over any of the PC machines of its time.
I had mine running Solaris(2.5.1) then later on made the move to NetBSD. Linux was far to immature to run stable on the early sparcs.

You can download a service manual for the Sun Sparc LX Service Manual.
You can find images of the whole system on my flicker.

Here is a nice image of it busted open
