- I have a sun 2/50 that I would like to get working a again, (I know,
- a painful thought, but I can't stand to let it just sit there), but
- when I power it up it never gives me a display (or tries to boot).
- It appears halted in a power on test. Below I have described what
- the LED's on the back show. Does anyone have an old tech manual or
- just happen to remember what this pattern means?
-
- Power on (looking at the back)
- The LEDs chase from right to left (from 8 to 1)
- If I number the LEDs as follows: 1-2-3-4-5-6-7-8,
- LEDs 1 & 5 come on and then immediately switch to LEDs 1 & 6
- The machine now appears halted.
-
- Any help would be appreciated,
-
- -Dave
