aaaaaand this right here is why I need to get myself a hot air station
I don't have one. I used a hot air gun, the kind you use for stripping paint. It's crude, but it works. The chips fall off when heat is applied.aaaaaand this right here is why I need to get myself a hot air station
Do you mean the decoupling caps? I was reading about how they reduce interference or something like that. They need to be installed if they are missing: I tried using one of my newly made up 1400 modules without adding them in and the computer crashed with an address error on the Welcome to Mac OS screen. That problem went away once I added in the caps.What should we know about the SMD caps if attempting this mod?
I googled this and there is a range of acceptable values, it seems like around 0.1uf would work OK.What values are they? It would be useful to know now in case I'd want to do this mod in the future.
Just looked at my Apple 8MB RAM card, and its caps are labelled A5 — 0.1uf.What values are they? It would be useful to know now in case I'd want to do this mod in the future.
Yeah, assuming they’re not too big. The ones on my donor board fit my 520 module, but not my 1400. Might be good to have some spares on hand just in case.ah, the RAM board has them to transfer. Good to know, thanks.
Yeah, that's what I was told once by SiliconInsider when I inquired about it. So for now, the method of swapping chips from donor modules seems to be the most feasible option at the moment.How easy would it be to make up a PCB for a 32MB PowerBook 500 series RAM card at somewhere like PCB Way? Because I was thinking about making some more of these that I could potentially sell…
Edit: Oh - it’s the connector that’s the problem, isn’t it. (As in I’ve heard they’re unobtainium)
I think I see a PowerPC upgrade card as well…this 32MB RAM card from Techworks was purchased back in the mid 90's at or around the time I bought the PB520
You could always get a second hand SE/30 to restore, as I’ve been doing. It’s my favourite machine.i don't remember upgrading the processor, but lifting the lid a little wider reveals "XPC603" so I think you are right! wow. I totally forgot. however, when I go to control panels "power macintosh card" or "601 processor upgrade" I get the message "doesn't work with this macintosh". what tools should I load to see/leverage the ppc card? btw, thanks for noticing this. 20 or so years ago I made a "Sophie's choice" between my pb520 and SE/30 and kept the PB520 because it took up less space and was newer, more powerful and expandable with color and all of the ports. This last couple of years since I got into vintage computing I've been kicking myself for getting rid of the SE/30 (and still am), but now I feel a little better.
got a 512KE, Plus and ClassicII running. Been mostly focused lately on modifying RaSCSI to connect my and a buddy's old macs together over the internet. Am always on the lookout for an SE/30.You could always get a second hand SE/30 to restore, as I’ve been doing. It’s my favourite machine.
I’m not sure there are any drivers needed to activate the PPC card, but other members may be able to advise better. It’s a cacheless card, so performance will be roughly on par with a PB 5300.
Ok you have enough compact macs. You’re finegot a 512KE, Plus and ClassicII running. Been mostly focused lately on modifying RaSCSI to connect my and a buddy's old macs together over the internet. Am always on the lookout for an SE/30.
hahahah. yeah. I'm not hurting and have plenty of 30-40yr old projects to keep me busy. am enjoying learning about appletalk and mac networking
