Let's go an Amiga 2000 with ISA SBC 286, 386 and 486 boards inside :)

I've got the same card, it doesn't like living in my IIfx - even with 24bit addressing turned on. See here for options to "see" the 384K RAM - either using HIMEM.SYS or another variant of DR-DOS which uses EMM286: https://www.vogons.org/viewtopic.php?t=71533 A nuisance! But an overclocked...

I'd suspect a marginal PSU - check voltages with the ADC display running, also wake from sleep crashes were usually related to USB or third-party card issues - try pulling them and reintroduce one at a time.

Usually these failed from bad CPU transplant or cache

If anything like other DOS compatibility cards, the socket won't be that to take the 237pin Socket 5 POD CPU package - it's a line of pins wider than the standard 486 Socket 3 (169 pins).

That's a fairly long stretch there, it's not like it's some evil strain taking over our precious PowerBooks! It appears common under particular storage conditions, and countries, notably older machines originating from Japan. A similar phenomenon occurs with early PowerBook 100 displays - a...

It doesn't matter, they're all the same SCSI/IDE etc.

Lots of fun in that lot - you've covered 25+ years of x86 computing for $19 well spent :) I recently built up a Core2Duo 9600GT GPU PCIe based system as a Windows XP beast for a friend. Works great and I'm almost sad to hand it over.

https://forums.macrumors.com/threads/quicksilver-processors-compatible-with-gigabit-ethernet-g4.1183181/ You lose the second IDE connector, but not the CD-ROM drive if you want to set it off the slave connector off your first IDE connector, or look into an ATA/SATA PCI IDE card.

Hands up if you spent a good five minutes with your Google-fu skills to try to find it :D No $500 here.

So you haven’t tried wiping it off yet?

I'm trying to help to steer you in the right direction with the limited information you've provided. Good luck.

I admire your ambition! If I can understand what you want to do (transplant a single 7455 onto a stock Apple 7400 board?), unfortunately this isn't going to happen without significant electronic engineering, costs and time. A dual CPU on a Sawtooth is possible, but at diminishing returns...

Ideally go for the faster HPV PDS graphics card, the PDS AV card also has it's merits though if you want some input options. Both are pretty cheap. Dry thermal paste on a crappy little heatsink on the 7100 is like wrapping it a blanket as soon as you turn it on. The 601 CPU on the 7100 is...

Welcome, Sounds like you're looking for a processor desolder and swap - which is feasible on some aftermarket G4 upgrades, but less common on stock Apple CPU daughter cards owing to having slower cache that can't keep up with the newer CPU. I don't think you're going to get far using the stock...
