- how many others have older 530 machines (ca. early 1991) that have many little patch
- wires on the scsi and ethernet device boards?
- one of the boards actually has a patch IC upside down on the board!!?
- (am i overly sensitive to think this is disgusting given what we paid for the machine?)
- would i be right to think these patches were applied by hand?
-
- i begin to wonder about these boards because that particular machine has not
- been right (either scsi or ethernet) since we bought it last year, although another 530
- and a 550 have been not too bad.
- the ROS levels on all our boards are fine, and the drivers were up to date last time
- i checked.
-
- i've also heard a rumour that there were problems with the power supply in early machines.
- (power supply problems, either internal or external, would be consistent with some of
- the effects we've seen.)
- my informant was told this by an IBM technician elsewhere, and
- some problems he was having that were similar to some of ours went away
- once they'd put the machine on an UPS.
-
- you might think i could just ring up IBM UK and get someone who knew about the hardware
- to see to it, but you'd be wrong.
-
- at this point, any old rumour or suspicion will suffice.
