I bought what turned out to be a matched pair of extremely basic Farallon AAUI adapters, unlabelled with any kind of model number either inside or out, off eBay a year or two back (maybe they just wanted rid of them so gave me two for one?), and was dismayed that I could not get them to work...

This sounds like a great idea in theory, but I'm a tad unclear on one detail: How can you strip out ALL the 68k code from a 7.x system and still have it work? I was under the impression that there was still emulated 680x0 code scattered throughout until well into the OS 8.x days. Or do you only...

The one I unfortunately killed during recapping had the 4 EPROMs. The one I bought to replace it has the 4 regular ROMs. I didn’t have them side by side, but as far as I can tell the boards are otherwise identical, mystery ROM size jumper and all.

Ouch. Network Gremlins are among the most pernicious and hard to exorcise, at least in my experience. It might be worth starting a new thread for help with that. There are a few things you can try, though with regards to the specific issue you mention, I think the vagaries of Windows file...

Huh. Being able to move software etc. around without needing to resort to SneakerNet is so useful that getting them connected (at least within the house, and to the Internet if possible) is one of the first things I do for any machine, new or old, that I own network hardware for. Given this...

I got started on an, in hindsight perhaps overly ambitious, card that would have sockets for both FPU and ROM expansion. (The two expansions are more or less completely orthogonal, only sharing physical space.) I got a bit bogged down in trying to choose a PROM technology. Flash would be best...

Ah, thanks for finding that! Interesting reading there.

I frequently get on sites like the Macintosh Garden from my Quadra 840AV using Netscape 4 (4.3.2, IIRC). It seems to work quite well if you don’t expect CSS, though it does get “broken pipe” errors if you try to follow an https link. (Not a surprise, it’s too old to have any encryption protocols...

Alas, nothing else I have will accept a PlainTalk mic. There must presumably be some way to test for voltage as I shout into it unplugged, but I don’t have any idea what it’s SUPPOSED to do there. Also, what voltage is it expecting on the supply contact?

I think it may actually have been a PRAM issue. For the past few weeks it’s been working perfectly, without my ever having had time to do anything to it. It probably helps that this board had next to no cap goo on it to begin with; the recapping was largely preëmptive maintenance. (By all...

As “investment” collectors’ items, IIgses are worth about $20, regardless of ROM revision. You can get five times that if you have a nice specimen and a buyer who actually wants to use it as a working machine. ROM 00 units appear never to count as “nice specimens” to an actual user on account of...

Hah! Got to find one first! Good trick if you can manage it. }:¬D

Sorry mate, the seller took it in partial trade. If another one turns up cheap I’ll point you at it though.

Good to know. Gives me options for my hunt for a PowerBook 5x0c model. Thanks!

And if it does work, does it then allow the machine to run at the higher speed? Seems like it maybe ought to, but it also seems like the logic board in the 520 might not be capable of 540 speeds. Depends how cheaply they made the things, really.

In addition to planning for an analogue board recap, I have purchased an already recapped logic board from one of our comrades here. I haven’t the patience to fix corroded traces on the board. Not very impressive of me, I know, but I want it working sooner rather than later so’s I can work on...

…Ah. Drat. That probably explains a lot. OK, I guess I know what my next working evening is going to involve.

As you may have seen in my post in the Compact Macs subforum, a friend helped me recap two Macs over the past few months. The Classic II was a dismal failure, but the 840AV seems to work… Sort of. It tends to freeze up when I tell it to shut down. That’s under a freshly installed OS 8.1. I’m...

The video is at least not jumpy or flickery, but you’re right, it shouldn’t be anywhere near that dim. UPDATE: I just tried it again and now there is no video at all (doesn’t even light up). Can hear the hard drive seeking to see if it is present, but that’s all it does, and still no chime...

Could be worse, at least I haven’t apparently destroyed anything yet. On closer inspection it turned out that 3-5 or so of the caps were only making contact on one side. See, it turns out that when you order polymer SMD caps, they have hardly any contact showing at the side, it’s almost entirely...
