OK, I populated only Bank A with the 16MB SIMMs - nothing in Bank B - and the test is running now!! Its still going but its no longer hung. I am running the system outside the case - I need to see if these SIMMs will physically fit while in Bank A with the logic board back in the chassis they...

Are there instructions somewhere? The "Apple Memory Guide" I found doesn't mention 16MB SIMMs at all - page 4 is about the SE/30: http://www.applerepairmanuals.com/the_manuals_are_in_here/Apple_Memory_Guide.pdf I mostly don't want to move things around too much out of fear of breaking the...

So, I am curious about testing my RAM. I've had a couple programs hang/crash (says "error 1" - which google says is check memory) and just wanted to make sure it wasn't the RAM I purchased. So I downloaded ISO from link you provided. I'm running the RAM test but it hangs the system...

I thought this was interesting. I enabled 32-bit addressing in System 7.1.1 "Memory" Control panel. Later, I booted BlueSCSI from an SD card with System 6.0.8 and I received this message: If I click "24-bit" then I can start System 6.0.8 - but when I go back to 7.1.1, then 32-bit addressing...

Plus its at the lower end of the price spectrum if you're in the USA :) Another feature that was important to me was the board thickness - which you raised in your video. I wanted to minimize chances of issues. I used my digital calipers and the GW4402B is actually a few hundredths of a...

Thanks for this explanation. Now I understand why 6.0.8 shows the amount of free memory it does. This also explained my issue with System 7.1. I have the 32-bit clean replacement ROM installed, but the Memory Control Panel had 32-Bit Addressing set to OFF. Once I turned it ON, now I see...

Yes, I watched your excellent video and picked Garrett's Workshop GW4402B replacement ROM SIMM. Its great having both System 6 and System 7 ROM disks available via a DIP switch - at first I had some 2MB SIMMs installed where the 16MB are - and the system wouldn't boot into System 7, but it...

Yes, I have 4x256KB in Bank A.

So, I installed the Qty four 16MB SIMMs in Bank B and everything is fine. I'm am curious about trying different arrangements - but I want to minimize flexing the plastic tabs on the SIMM slots, so I'm not going to move anything around. One interesting thing is how the amounts of free/used...

Thank you! I stumbled across this and am using your preconfigured version with a BlueSCSI w/Daynaport emulation as a general telnet client - it has the best vt100 emulation I've found for connecting to linux machines on my local network. From there I can run links2 (www), IRC clients (irssi)...

Is there a good stress test / memory checker I should run on my 65MB setup? I just wanted to confirm its good before I go and button up the enclosure. Right now I am bench testing the system with an ATX extension cable.

In the thread above, at least with a stock ROM, user JDW could only boot with the 16MB in bank B and something else in bank A. He tried reverse and it wouldn't boot, so thats why I didn't consider Option 3. Putting the 16MB in Bank B also has the advantage of more physical space - the 16MB...

I acquired an SE/30 with only 1MB of RAM - four Apple branded 256KB SIMMs in bank A. I purchased four 16MB SIMMs from OWC. I have a Garrett’s Workshop GW4402B replacement ROM SIMM for 32-bit clean support. My question is, do I: Leave the 1MB in Bank A, install 64MB in Bank B, for a total...

Does anyone know the pinout of the 15-pin ISA edge connector ? I've searched online and can't find anything. I thought it would make for good test points - I am troubleshooting an SE/30. So far I've figured out pins 8 and 9 are +5V and pins 10 and 11 are ground but thats it. Didn't find...
