Could be refresh related, try a CRT monitor if you have one.

You can go crazy with RAM 16x 16MB SIMMs is 256MB, I even had a max out Daystar PPC card with another 128MB but generally 64MB is more than enough.

I have a battery bombed IIvx I snagged to put a Quadra 650 motherboard into. Found the Quadra board at a recycler ages ago and the IIvx was offered for shipping because it was toast (back in 2015). Time flies. I would try to save it since the IIvx isn't exactly that common and that board...

Max is 2MB VRAM, the very high end NUBUS cards were 3-6MB I think. Built in video on a Quadra is plenty fast but color depth gets limited because of VRAM. https://everymac.com/systems/apple/mac_quadra/specs/mac_quadra_950.html "The onboard video can support 512x384 at 24-bit and 640x480...

I have a Daystar 68040/40 that was modded by somebody to do over 50Mhz, but it does have a fan on the heatsink.

Nice. It's been a long time since I have had a massive computer haul like in the good old days, just some things here and there.

I could never sell my 950's too cool and too many useful Nubus slots. The front panel is the only bare unpainted plastics on the machine so it will yellow sometimes. Did you get keys with it? 30 pin SIMMs are probably going to be harder to find then the good old days but even with 16 x 1MB...

I used to burn a bunch of CDs when I first got into 68K and early PPC macs, but I prefer original media for installs so I collected quite a few of them.

BASIC testing means remove what isn't needed to boot and use 1 good RAM stick.

Apple had the numbers of sold machines to entice developers plus the software team to help them if needed while Commodore had neither with the Amiga. Let's be honest the top seller was probably the A500 which is nothing more than a game machine (no networking or hard drive nor VGA video). Once...

Generally, I would recommend you wipe the drive and format it when attached to the third party IDE/SATA card instead of just using a drive from another machine. Also 6 PCI slot machines are picky on which set of slots you use for storage (because of the bandwidth used). Back when OSX didn't...

First RAM stick isn't clicked in.

The original Wallstreet also came with the crappy 800x600 DS screen as an option. The major difference is the originals had the 66/83mhz FSB and the later needed PC100 RAM, the second generation was just 66FSB.

Hopefully some of the main chips didn't get destroyed or lose too many legs.

9600 slots seemed pretty deep and tight to me for the thick CPU to sag in any way. I would be looking for weak PRAM batteries, marginal power supplies, or general capacitor issues that come with age. Old computers, Cars, stereo systems etc. all seem to age badly if not fired up every so often.
