  1. Is it possible to do larger than 4Gb disk images with the baremetal version? I assume the SD card would need to be formatted exFat for it to work? Whats the size limit on the standard install of RaSCSI?
  2. I got it working! My Pi Zero had the GPIO header already soldered on when I got it. And I had attached it to the top of the RaSCSI board per the Wiki assembly instructions. Well it was upside down. There are no pictures of assembled units anywhere so what might have seemed obvious to some wasnt to me. So I assembled my second board with the female header on the bottom of the RaSCSI and now it works as expected.
  3. This page says both 3.3v and 5v should be illuminated: https://github.com/akuker/RASCSI/wiki/Connecting-the-RaSCSI I tried it with Termination set to on and set to off (both switches). I tried it with the device powered before the Mac G3 was on and the mac would never boot. Also tried it after booting: SCSI cable connected and then power applied to device and the computer freezes until I remove power from RaSCSI. Should the 3.3v light be on when powered? I only see 5v illuminated connected to mac or not. I have another RaSCSI board I can put together and spare Pi-Zero. Might try it with t
  4. Greetings, I assembled and connected my RaSCSCI Fullspec v2.3 to a PI-Zero W and loaded up the 1.5 bare metal build and a sample disk image. When I connect power to the RaSCSI, only the 5V light turns on. Should the 3.3V light also turn on? It freezes the mac it is connected to externally when powered (Beige Mac G3). Any troubleshooting steps would be appreciated. Thanks!
  5. Update: I ordered the DRAM chips in my previous post. It turns out UM1 was NOT bad. After replacing all four "standard" ram chips on the IIgs mainboard the error still appeared and programs still would not boot without crashing. As I learned recently: those four chips are BANK 0. BANK 1 is the "Fast Ram" (UH13,UH14,UH15,UH16). After replacing the four chips in BANK 1 the system passed all tests and is working correctly now. I hope someone finds this information useful. Another Apple II saved from the landfill!
  6. Greetings, My brother picked up an Apple IIgs for me from the thrift store yesterday. I am getting an error: system bad: 02010400 when I run the self test by holding command+option during boot. From what I can determine, this is a ram error. I removed the add-in ram card for now and re-ran the test with the same result. Does this error show ram chip bank 01 is bad? If so, would this be the chip "UM1" on the mainboard? And last, are these the correct replacement chips: http://www.jameco.com/z/41464-10-Major-Brands-64KX4-100NS-HY53C464S-10-DIP-18-DRAM_41574.html Thanks!
  7. Yes I connected two different known good drives internally. An 80MB and 350MB. The drives are seen and will boot the system when I put them in an external SCSI enclosure and connect them. Is there a filter capacitor for the internal SCSI connector that may not be working?
  8. Hello all, I recently recapped an SE/30 motherboard. I cleaned the board with a toothbrush and soap and hot water, let it dry for a week or more and then replaced the capacitors. All the chips and traces look good on visual inspection. It boots and works fine, but the internal SCSI bus will not see a drive. I can connect an external SCSI drive and it can boot from the external but still not see the internal drive. I've tried a few different drives. Also, I suspected it may be power related so I replaced all the capacitors in the Sony power supply and recapped the analog board as well, no cha
  9. This is awesome. How is the SE so white?
