Early last November I bought about half of the stock Marshall claimed
they had available on-hand at the time (10 of 25 units available) (I
have 5 machines to repair and I wanted some spares so I could screw up! ;-).
The only trick with Marshall is that they have a minimum $100(USA)
order, so I also got a couple of 32MB SIMMs for the Multia too at the
outrageous price of $103.81(USA) for the pair (they were about $70(USA)
on the open market back then) -- but it was the only other thing
Marshall had that I needed and they had already gone up from $98 when I
got a quote from them a week earlier.
The part number I ordered was the TI SN74ABD623DW (there doesn't seem to
be a Marshall part number on the pick sticker, but I had ). They were
$1.52 each, if I can read my notes properly now.
Ordering them was quite easy -- I just phoned the local Marshall office
and gave them my credit card number. A big long box full of stuffing, a
small anti-static box with the two SIMMs, and a long static bag
containing a 20" chip carry tube with the 10 chips (that's 75% empty!)
arrived a few days later from California by FedEX (and with a $USA
charge on my credit card even though I telephoned a local office ;-).
Someday soon I'll get around to actually attempting the repair... maybe
sooner now that I'm looking forward to getting an AlphaPC 164 too and so
will need one as a kernel test machine. Too many machines -- not enough
