Thanks so much for the advice. I was not aware that the risk persisted even after unplugging from power!

Dear Stapleton, I am humbled by the investment of time and thought that went into your response. I feel confident that your suggestions are sound and well advised... plus they just make perfect sense. But I take pause on the basis of your capacitor warning. I expect that I will just be...

Thanks for your reply, Brooklyn. I tried that to no avail. But I agree, and am inclined to believe this is something simple. The machine is brand new and everything inside is pristine... but it has sat for over 40 years, so anything can happen! Here are a couple inside pics...

Thanks for the reply. Troubleshooting further is probably above my pay grade. I have never had a Lisa before. I wish you luck with your projects(s)!! Here are a few pictures...

Thanks for asking! Before I posted my question, I scoured the archives for similar issues and saw a few people talking about the issue you have... perhaps you were one of them. However, I do not have that issue. When I plug this in, nothing happens UNTIL I hit the power button, at which time...

Dear members, I have been unable to find any discussions that address my issue specifically, so I am posting my own with fingers crossed. I have a Lisa 2/10 that powers on (fan noise and illuminated power switch), drive light comes on for a second, and I even have raster (stable non-scrolling...

Dear Members, really hoping I can fix this... Have a Q700 with a Colorsync 17 plugged into the Radius card and a M1212 Apple 14" trinitron is connected to onboard video... which I have upgraded to 2MB VRAM. Running 8.1, but have same issue on 7.5.5 and 7.1. Only resolution options...

I recently acquired this beautiful card and eagerly pressed it into my Quadra 700 running 8.1, but it won't display an image of any kind on any of the CRT Apple displays I have tried to connect to it. (14" Trinitron M1212, 16" Trinitron, or Applevision 750) I have inspected the card thoroughly...

Dear Quadra 700 owners. Maybe you could help me clear this up. Which are the correct covers for the expansion slots. (see photo) I see both advertised and they cannot both be correct! Thanks!

Very Interesting! Thanks for your information. :)

Thanks so much. Kind of disappointing news... I was/am not sophisticated enough to know about RAMDAC chips. I thought it would be a 24 bit card up to 1024 or even 1152. I paid $130... probably too much. I really wanted to drive at least 1024 on my M2494 Multiple Scan 17 Trinitron. I...

Hello Phipli, Thanks for your reply. I am humbled by the span of your knowledge, as you have weighed in on many of my questions. But I am confused by some conflicting info I am seeing. 1. in the thread (linked below) a card identical to the one I have is identified as a Pro 24X. 2. If it...

I just bought this card on eBay. (pictured) I was curious if anybody could tell me if it was a 24XK or a Pro 24XK? Also, what is the purpose of the jumper? Thanks so much!

Wow, thanks for taking the time. That's a beauty... and looks like the original, just without the little brackets. I will get one like that. I saw previous posts on this thread suggesting the heatsink might be unnecessary. But I am more comfortable with your suggestion. Thing feels hot to...

Thanks Phipli! I will do so. As a collector and somewhat of a purist, I would love to find the original... much like I would prefer finding the original speaker module rather than mocking up something. But in the meantime, you bet! I will get an Amazon 40mm heatsink and pull an 8ohm speaker...

Thanks for easing my mind on the impedance issue being in my favor, safety wise. Is polarity critical, should I mock up a speaker from another source?

My apologies... I was not clear on your earlier response re corner pins. Now I am with you.

If my stock Quadra 700 has no heatsink at all, should I even be too concerned about locating one? Thanks!

Oh, and here are clippings from a Quadra 700 take down video I found on Youtube. It shows just two wires going to that 3-terminal plug. Perhaps someone with a Quadra 700 could tell me which of the 3 board pins is not used. Please let me know if anyone has a Quadra 700 speaker they wish to...

I really appreciate everyones's input. I was about to buy a IIci speaker module on eBay, but I paused to research when I noticed a 2-pin plug in the photo... compared to a 3-pin connection on my Quadra 700 logic board. (logic board comparison photos attached). I was confused by this and...
