<div><p>The 1E uses the SBus as it's main system bus, and uses the S4-VME

memory.</p><p>In regards to the connector, the P2 connector is the second
(lower) connector on the VME backplane, the unused outer row of
pins on the P2 connector is used as the memory interface on the
1E. So the cable would be installed behind the backplane (like you
would a paddleboard), while the pinout on the 1E's P2 is provided
on the 1E manual, I don't have a copy of the 1E memory manual to
find the pinout of the P2 connector on that (or the registers for
the memory controller on board the memory expansion card). So to
expand the 1E you will need a 1E memory card, and the correct
backplane cable to connect them.</p><p>As for mapping generic memory cards, that will be quite tricky,
while you can use the /dev/vmea32d32 interface to talk to it, to
use it as memory would require modifying the OS and OpenBoot to
add the correct ranges to the 'available' attribute. However it
won't be cacheable and will hurt performance.</p><p>If any one has a copy of the 1E Memory board user manual that
would be helpful.</p><p>So if you want to expand the memory on a 1E, you will have to
find a memory board and create the special cable, I can only
assume that it's a straight through cable, but besides from that I
don't know the details.</p><p>Cheers,<br>

Sadly they are all I have…I was working on the theory that
owners of the 3/E would have upgraded to the 4/E without

<div>Much like the 3/260 to 4/260 upgrade I did back in the
day. Remove old cpu board insert new COU board, install
fresh OS and keep using all the memory boards etc.<br>

Maybe there is incompatibility between 3E and 1E

folks<br>
<br>
Looking for some
suggestions/guidance or help.<br>
<br>
I am Looking to add 2x 4Mb Sun 3/E
memory boards to the SPARCEngine 1E.<br>
<br>
I do note that these are memory
boards from the Sun3/E but am of the
understanding that they will work.<br>
<br>
Reading through the SPARCEngine
manual I have added the jumpers to
my schroff Backplane to bridge slot
2 as this is empty - the sbus video
card occupies the slot.<br>
<br>
Configuration is<br>
Slot1: SPARCEngine<br>
Slot2: jumpered and empty<br>
Slot3: 4Mb memory bord jumpered for
4-8MB<br>
Slot4: 4Mb memory bord jumpered for
8-12Mb.<br>
<br>
Now on post I don’t see the extra
8mb.<br>
<br>
Anyone got any ideas ? I read
something about telling the nvram
about the VME cards but not familiar
with that process or how to do so.<br>
<br>
Thanks in advance <br>
<br>
Richard <br>
