"johnklos", _You can not make it work without the help of PLL chip in any way_! (PLL stands for Phase Locked Loop, check Google or Wiki how it works, in caseYou don't know.)In all…

Hi guys, Although we often mention Marc Schrier's page, we all should give a credit regarding this mod to that person from Japan, namely Hiromasa Yamaoka who was first to do suc…

Something else just occurred to me on the overheating possibility. Could it be the HD that's overheating and not the system? Tempest

The games will immediately crash again if I open them. But like I said it's not all the games, just certain ones. I'll crack 'er open and see if there's something loose inside or…

Ok yet another wrinkle. I had the Mac turned off for an hour or so while I did something else, came back, and now everything works. Shufflepuck, Fools Errand, Gunshy, they all wo…

Hmm... Just got an Illegal Instruction error in the control panel again. Could just the presence of a bad program in a folder cause the Mac to go wonky or does it have to be 'inst…

I may have spoke too soon. Booting from a System Disk I still get errors in games. Shuffle Puck Cafe crashes with an illegal Instruction error after the Broderbund Screen (might …

I've been using Stuffit Deluxe 3.0.7 under System 6.0.8 on my SE/30 for ages now, although I must admit I don't use it that much at all. I use Stuffit Expander 5.5 more frequently…

I think you're right. Oddly it did work under System 6, it just caused everything else to have errors. Where can I grab the latest 3.x.x version? I assume that they're freew…

You never know - companies are still buying them, so it's just a matter of time before some older product becomes "obsolete" and the chips work their way onto eBay. Or if a company…

Tempest, Bear in mind that version 4.01 was written during System 7's era. It wouldn't surprise me much that you may need to upgrade to 7 to fix the problem. Otherwise, try down…

On the other hand, if you can get your hands on a Freescale made m68040 Click to expand... Yeah, like that's gonna happen. They are like $250-$300 each in bulk according to Fre…

With the help of a friend I finally have my Mac plus up and running. It has 4MB, a 500MB external HD, an CD Drive (an Apple CD150), and is running System 6.0.8. At first everythi…

Thanks. I did the MC88920/88916 swap, and pull pin 9 high (?) or something like that.http://homepage.mac.com/schrier/q605_40.html on one machine but could never get video. But…

Would you still need a heat sink/fan if you were using an 040 that was actually rated for 40mhz? Click to expand... Yes. The 40 MHz part is made exactly the same as the 25 MHz …

What do the winners win? Click to expand... crap prizes. :lol: Click to expand... HEhehhehehe

At first I swapped resistors to go to 33MHz and afterwards I installed 40MHz oscillator, as per instructions on Marc Schrier's page. http://homepage.mac.com/schrier/q605_40.html'&a…

What do the winners win? Click to expand... crap prizes. :lol:

They win a Retro Challenge Mouse Pad, an original first-edition copy of 300 Baud Magazine, and... a CD of tunes made on the Apple II.

Would you still need a heat sink/fan if you were using an 040 that was actually rated for 40mhz? I have two of them installed in 33mhz machines that I want to kick up.

Hi trag, Yes, I've modified Q605, not LC475, althoug I've put a jumper on the MB after I went to 40 MHz, which changed its gestalt ID to LC475. At first I swapped resistors to go…

nb: 40MHz is not always stable though. A heatsink/fan for the 040 would be a good idea. Click to expand... I can confirm it - at 40 MHz heatsink is a must and you should use a…
