Most soft power Macs don't require batteries to power up successfully, exceptions for the 6-slot Mac II models. The only hard-power Macs that require batteries to start up are the '040 and PPC-based models. Even then these will power up but they won't boot; you need to do a jumpstart (either quickly flick the power switch off and on or press the reset button a couple times) to get the CUDA chip to work properly and allow it to boot. With the introduction of the '040 the LC PDS was decoupled from the processor: it now runs off of an emulated 16MHz '030 bus provided by the new PrimeTime IC (which also provided the same '030 bus to the Comm Slot). This was done because the '040 does not support the byte steering or dynamic bus sizing features of the '030, so they just emulated it to enable the continued use of your legacy peripherals. The same thing is true of the PPC models w/LC PDS except they're also running an '040 emulator to talk to the '030 emulator; this allowed them to use up their old stock of chips and for you to continue using your old LC PDS or Comm Slot cards (except the Apple IIe card, which required 24bit addressing that the later '040 and PPC models don't support).

@@minty_Joe that memory check is for later PPC macs, as far as im aware classics macs dont allow that as the memory test is performed on boot up by the ROM itself. you can however patch a 68k mac rom to remove that check (and you need to disable rom checksum check too). the lc575 can accomodate a 64pin rom socket that would allow for a custom ROM to be installed and used should one want to go that route. however getting those sockets is very difficult as you would need to source a NOS part as no one makes them anymore

The long wait time on boot for the LC575 board is due to the ram test. Imagine having 132Mb Ram ;-) - The PCI-like slot is the communications slot and supported mainly modems and network cards. The CPU can be safely overclocked to 33mhz. The Q605 and LC475 share a similar mainboard design and can be overclocked the same way. You may encounter some sound problems depending on the mainboard (maybe due to age or revision?). The perfect companion for this machine is the Apple IIe PDS card. When paired with an ethernet communications card (comm slot), you have the perfect all-in-one 68k/Apple IIe machine. There may be some problems when using the Apple IIe card together with the comm-.slot card. I had no problems though. I didn't even need to do the 512pixel screen mod. My LC575 board just worked (i did no overclocking since the machine is fast enough). I would recommend the 640 resolution mod. It helps with newer games and programs that need a minimum of 640x480.

Some Mac II's (and maybe others) need a working battery as the power supply doesn't have a standby rail, so for the soft power to work the power supply needs some juice from the battery on the MB to initially power the relay that connects the mains to the PS. Basically they took an AT-like PS design and shoehorned in soft switching. I think that's why it was suggested

Adrian you can overclock the lc575, you need to change the oscillator and lift a pin on the clock gen chip check out this page for instructions.. fwiw most macs ever 601 ppc based ones can be clock upgraded to run faster using the same basic mod as ive linked here: web.archive.org/web/20040723063623/gabezing.sytes.net/lc575-40mhz-e.html as for the delay with the screen turning on that is because the mac is doing a RAM test on power up, the more ram installed on those classic macs the longer it takes. for sound issues its likely the sound amp on the analogue board (or parts relating to it such as bad caps etc) its a common issue on these color classics. you might also want to reconsider the screen res and actually do the the hi-res mod to use 640x480 as with the LC575 board, CPU clock upgrade and the addition of the FPU variant you installed this is a very capable 68040 mac but most software from that era of CPU macs won't run on anything less the 64x480 . its an easy mod to the analogue board and you really won't regret doing it. the trinitron crt is actually dot pitch wise quite capable of the higher res. the main reason it has the 'weird' default res is due to the fact that these macs were often paired with the Apple II PDS card for running apple II software on it and sold as an upgrade path from apple II's to schools if you need any further info let me know

That brown header next to the PDS slot is a COMM I slot. They had internal modems/FAX modems and early Ethernet cards available for these machines and the back plate had a knockout for the phone/RJ jack. There was also a COMM II slot that was faster but the key was different so you couldn't install in the other COMM version. If you went with the extreme TAKKY 6400/6500 CC upgrade you could go with COMM II. This slot was probably not faster. Some PDS video capture cards (Video Spigot) would instead use the knockout for the video input jack so you'd have to nix the modem or mod the back cover I'm guessing to have both(?).

Once yo have a functioning one it should be able to trace where the Audio is not passed through, Somewhere the signal must be leading to a dead end, Mind you the signal could also be shorted to ground somewhere. If that is a dead end, check to ensure the Audio controller chip is receiving the right low or high signal "enable/disable" "AKA Mute/Unmute" or set Jack to Mic in or Speaker out AKA "input or output" so on and so forth..

Can the 68040 mac boards be upgraded to 68060s with voltage regulator adapters? I know that Amiga people have been doing that with their 68040 accelerator cards. Interestingly, MacroSystem used 68040v chips in their DraCo and classic Casablanca video edit systems. The 68040v is the same voltage as the 68060, so it allowed them to provide easy upgrades to their "render accelerated" machines by swapping chips.

Guessing that extra slot is for a video capture card. You mentioned the PDS slot connects directly to the CPU bus, but this wouldn't have access to the video memory as that would connect to the video chip. Without direct access to the video memory, this would have to go through the CPU, which would be too slow for playing video, which is why a separate slot would be required that does have that direct access to the video memory. It may also have some analogue connections for video overlay. Anyway, good to see the machine up and running! I wish I could work on my LC575, but the plastics are just so brittle that more of it breaks every time I work on it.

I kind of wish there was a all-in-one style chassis for the Apple IIGS reusing a color Mac but the GS coming out almost 10 years prior and being discontinued a year before this even came out give or take would make that a no go. It'd be a bit of a pain wedging in the GS board and have space for all the expansion slots unless you gutted the area for the disc drive/hard disk. No way I would chop up an original chassis, I'd end up fabricating/machining a replica out of metal like I've done with a few Amigas and Apple IIc's. Ah well, I quite like the form factor of the GS anyway. My Woz edition I got as a kid second hand has been a permanent fixture in my room and then office/study ever since. Apple's use of basically velcro for the pieces is a bit interesting, definitely easier to service than double sided tape that's for sure.

I've actually serviced a Mac that wouldn't turn on because of a dead battery. The thing is I'm not an Apple technician and I certainly didn't have any documentation for the machine. This was way back before the internet became the place to look for these kinds of resources. Manufacturers still used fax to provide service documentation. I remember calling a service number to end up at a automated phone answering board. There you followed instructions going through a voice menu entering numbers as replies to questions. The first thing you did was request the service index. Then you entered your fax number and in a few minutes the fax spit out the index on a few pages worth of paper. Then you called the service number again but this time you requested the service documentation using the document numbers in the index. And again you would have to wait for the fax to slowly receive these pages. Now back to this Mac. I have no idea what model it was, but I remember that it only had a power button on the keyboard, and whacking that did absolutely nothing. As we were PC builders I didn't think it was worth the effort to look for more than just the basics on this Mac, but my colleague was a bit more curious about just how the machine worked. Long story short: He ended up finding a dead battery inside the keyboard. Replacing that, which required the keyboards to be disassembled and involved soldering, got the machine to work. Now I don't remember what kind of battery it was. It might have been a nicad cell that went bad over time, or it was just a simple alkaline cell, I have no idea. But it was actually mounted inside the keyboard and not in the computer. Also I remember thinking it was pretty weird that they battery wasn't accessible from the out side so it could be easily replaced when needed, but then the machine had worked for something like four or five years before the battery ran out. We also tested the power draw, and as I remember it the only time there actually was a load on it was when the power button was pressed. Another funny thing was when the same customer came back with a very old portable Mac that needed some attention. I can't remember the name or model number, but it was one of those early models that had a relatively large track ball in front of the keyboard. Again it was a battery problem, this time it was the real time clock that no longer kept the time. A quick battery swap and it was good to go again. However the funny part was that the OEM Apple used had put it's logo on the motherboard, which was something I hadn't seen in a Mac before this. I'm not 100% sure, but I think it was manufactured by Acer for Apple. But I am sure that it was a big and well known Asian company. I kind of doubt that Foxcon or who ever it is that makes the motherboards for Apple computers today get to stamp a large logo on the motherboards today.

I feel very sorry for any woman around when you are working on electronics. Could you please stop sodhering her. Covering anyone with sods is never a good idea

Awesome video, such a short time demoing the speed improved version. You teased the network card and I want to see it go online!!

Adrian is very open about wanting feedback both positive and negative on these videos, which I respect. I would wager he actually gains some satisfaction when people thumbs down his videos, because they are being honest with him about their feelings. I don't feel this way, but I'm positive some people do it whenever he twists off a capacitor!

amazing job! enjoyed this. btw the 475/605 board could definately be overclocked as I did it although 40mhz was unstable so i went with 33mhz. it was a case of re-arranging some resisters.

Maybe you could bust out the old oscilloscope and see the activity on the legs of the sound chip or hook a clip lead on the output leg and try to see if there's any sort of sound signal coming out.

AFAIR, in their official communications, Apple called the non-FPU 040 the 68LC040. Also, the Performa 475 had a jumper that you could solder (either add or move or remove) to overclock it. Maybe there's something similar here?
