Awesome! I love my SCSI2SDs (I think I have around 8 of them). Any chance this might make shipping to Canada less expensive? I’m guessing not as orders are still probably fulfilled from the US but that would be great as I had started ordering them to my hotel when on vacation to the us to save on shipping.
I would start buzzing out all the memory lines per the schematic. If there is good continuity, there are a few chips related to memory that are generic and are cheap enough it’s worthwhile to just replace them. Of course that’s assuming the memory cards are good. I fixed my Classic that was only showing 512k ram that way (search here for Classic 512k ram or something similar)
@lisa2 It looks like that part is discontinued and out of stock. Would 4120R-601-250/201L be a suitable alternative?
Okay - so I might have spoken too soon. I recapped and cleaned my board today. I do not have a PRAM battery so first question is - will the IIsi start without one? I get no chime. Second question - what PSU Voltages should I be seeing? I have the following on the ten pins as I have the machine turned upside down with it "powered up".
3 ground pins
(1) 4.66 VDC
(1) 3.69 VDC
(1) -12.17 VDC
(3) 4.97 VDC
(1) 12.18 VDC
The 4.66 and 3.69 pins seem off. Any thoughts here?
