Yes, yes, that is the correct way to fix it (I have done many myself)...
the "whack it" comment was a tongue in cheek remark, since at one point,
that was actually an apple authorized temporary fix (until you got tired
of it enough to bring it into a service shop and have the joint
resoldered... since back in that day, you were supposed to open your own
mac... although I ignored that starting with my 128k). At one point, I
even found a tech note about doing it, although, they refered to it as
"tapping forcefully".

The very oldest Macs didn't have SCSI ports... However, a company
called Dove had a board that plugged into the ROM slots, and into
which you then placed the ROMs, that provided a SCSI interface for
the Mac 512k/512ke. They also had a memory board that had the way
of interfacing to the main board... it had funny-looking sockets
that "clamped" down on top of the existing DRAMs and which provided
enough to bring a 128k Mac up to 512k or a 512k Mac up to 1MB. I
still have both boards...

Subject: Philbrick?
While cleaning up some garage space (yes, so a Car could
go in there) I came across a cache of some things I knew I
had and one thing I forgot.
A 2 tube module.from George A. Philbrick Researches Inc.
It's a GAP/R K2-W with "computor" tubes in it.
Before anybody vomits (as regards computor) could
somebody remind me who Philbrick was?
The name seems familliar. TIA

Tsk, tsk; I would have thought that the SCSI fans would have more appreciation for Commodore's IEEE488 GPIB implementation back in the 70's: less pain than some people on this list have had with SCSI, addressable daisy-chained peripherals, more expensive and less selection just like SCSI, and no problems with termination etc. :-). And they could (and indeed did) talk more or less directly to a lot of high-end lab equipment, especially HP's, although admittedly not quite at the 10Mbps rate of today...
That is indeed what it is, Joe; if you actually want to use it, the DIP switch selects the unit address (usually 4 for a printer) and (if I remember correctly) the CR/LF and all-caps options. Still have a couple in fact, as well as a 1450 serial version; used one for many years to let my 8032 talk to my Centronics 101.

It is slightly off topic, though I hadn't seen an eisa card for what
seems like a decade :)
In any case, I recently got a 2nd hand AlphaServer 1000A with no disks.
I put an EISA SCSI card I dug up in the machine, but its wanting me to
run the eisa configuration utility. After scouring the net, I found one
that would come up, but only if I burned it onto a CD. Now its
complaining that It can't find a configuration file for my system board.
Grrr. I suppose I'm glad EISA is dead, but...it would be nice if I
could get this silly SCSI card to work.
Any thoughts/hints/suggestions?

Does anyone know where I might find a Stand Alone Utility (SAU) disk for a
Wang VS5E? Or maybe some OS install disks, or a old hard disk from one? VS15
or VS25 would work also-same processor (CP5)

Once you get the dance steps down, and realize that you have to sacrifice
a lamb, not a chicken... the SCSI gods stop causing problems. :-)

Hey folks. It is likely that I will be driving an empty 24' truck to
the DC area from the Tampa, Florida area within the next week. It has
a lift gate. I would like to defray the cost of the truck
somewhat...If anyone needs anything hauled along the 75N->10E->95N
route, please contact me off-list.
