Progress bar shows maybe 10% done after 4.5 hours? Mouse cursor doesn't move (why I thought the system was hung), the status message continues to be updated every 2.5 minutes or so. So I really think it would take more than 2 days to complete the Long Test on an SE/30 with 65MB of RAM. I've...

I no longer think its hung doing the "Long" memory test. The mouse cursor changes to a beachball and I cannot move it. However, the Status message "Now testing RAM at address $##### actually does update at intervals just under every 2 minutes. Only the first two digits increment so it seems...

Now the gremlin I am trying to track down is that MacTest Pro short and extended tests PASS in 64MB or 65MB configurations (with 1MB in bank B) but the "Long Test" hangs immediately in either configuration. "Long Test" also hangs immediately with 7.5.3 rev 2 and Stock ROM and MODE32 installed...

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...
