I recall (could be wrong) that this is a special "AT + 3.3v" power supply.
I had to hunt hard to find one for my Alpha PC64 motherboard. It cost more
than it was worth, considering the speed of the resulting box, but I'm a
sucker for vintage technology. FWIW, I found it at
http://www.computersurplusoutlet.com; ask if they still have the PS for the
I would also point out that the AXPpci33 is really, really slow (much slower
that the PC64, for example). Basicly I've found it to be on par with a to
mid-range '486. It can be slower, depending on your particular execution
profile, and very rarely faster. You'll hate X on it.
And as the previous poster pointed out, the required 72-pin ECC SIMMs are
shockingly expensive, and are needed in pairs. I recall they have to be
"single-sided" variety (12-chip) as well; e.g., not all SIMMs will work.
This rule apparently precudes using 32MB SIMMs, BTW (none of mine work,
anyway). You get 4MB, 16MB & 64MB options, although the odd-ball 12MB
Multia SIMMs might work. I suppose some 128MB would work as well, if you
could find them and were crazy enough to spend the money.
Were I you, and I really wanted an Alpha that slow, I'd look for a Multia,
which is nearly the same thing horsepower-wise without the ugly power supply
issues (and they come with X-compatable video, scsi, ethernet and usually
some usable memory). I find my Multia cute and nostalgic. Alternatively,
eBay always offers a number of compatable Alphas that are somewhat more
Best of luck!

I have one of those and I have yet to get it working. It
requires a power supply that I have never been able to find. Look at
the bootom right of the picture and you will see two rows for power
connections. One of them is for a normal AT power supply and the other
is for the PCI option bus, kind of a pre ATX power supply. You must
use 72pin parity ram which is dificult to find especially if you want
sizes larger that 16Mb.
