These are from somewhere in the NetBoot Mac OS 9.2.2 disk image. I'm not sure which file they came from. The Apple campus image is also somewhere in this disk image, but not the iguana flag. I realize this is a bit off-topic, but these discoveries have indeed stemmed from the PEX ROM. If a...

I found a better jpeg extractor and fed it my entire Mac ROM archive. Much to my surprise, here are the Quadra 660AV / 840AV hidden jpeg images :)

WEP gives you some protection, MAC address list gives you some more protection, but neither completely protects you. Using both of them is better than using only one. The reason the MAC address list is not safe is because there is an app for AirPort Extreme that allows you to change your MAC...

Another thing that you can do is to set up a MAC address list on your router. Every wireless adapter comes with a unique MAC address, and listing them in the router allows only those specific devices to connect. That will make it more complicated to hack and thus slightly improve your...

I'm thinking that you will need to make a script to do this unless StuffIt Deluxe has this feature built-in.

When you mention making an ISO of 9.2.2, what does this mean? Are you going to rip a bootable 9.2.2 installer CD to an ISO file? Making an ISO of a bootable 9.2.2 CD preserves the blessed system folder and CD disk driver I'm pretty sure. To my knowledge, you can not modify files on an ISO...

It appears to be a telephone cord, but it is wired differently. Using an actual telephone cord can wreck things I hear. I remember trying once as a kid because the original one was a bit stretched out, but the phone handset cord I had did not fit. To make matters more confusing, you can use...

The red circled ones are definitely bad. There is no visual indication to me that the ones circled in blue are bad, but as long as you are replacing some of the capacitors, you should consider replacing them all just in case the others are soon to follow. Capacitors can go bad and not give a...

secret about box images (see previous post)

MOTHERLOAD of JPEG easter eggs found in the 7200 / 7500 / 8500 / 9500 ROM! These are stored amongst the "secret about box" images. See the next post for those. (Max # of attachments is 5.)

OMG, there's one in the Power Mac G3 ROM too! :D Who knows how to access these normally?? This one is located at 0x2E6E80:2FC268 in the checksum = 0x78F57389 ROM.

How did PEX machines make it out of Apple? There seems to be a fair number of them out there. Were they actually released or given permission in some way or were they potentially stolen/leaked? Or something in between? It's one thing to poke around at things actually released form Apple but...

I figured it out! I didn't know where to find the end of the image data before, but after a little googling, I realized that they end with 0xFFD9. There happens to be an extra 0xFFD9 in the image data before the end and I think that could be what caught up the JPEG extraction program.

I found a JPEG header at address 0x2D14E0 by searching for "JFIF". I don't know much about JPEG so I used a program that finds and extracts JPEG images. The bottom half of the image is missing, maybe someone can tweak it and get the rest.

What in the world could this be? It sounds like it could have the same problem mine has. One thing I never tested was the power rail at the processor and ROM for voltage and noise. This is a very old machine and may have dried up caps or something. I never found any cap leakage on mine.

You make it sound like I was wrong when I clearly was not! How dare you!! :O -> > :( -> -> :scrambled: hahaha :lol: I have actually made that mistake once with some 7400 chips. I blindly chopped off a 4.5V adapter and wired it in, as the range is 4.5-5.5 for the ones I...

Could the lack of or incompatible MMU be responsible for 9.2.2 not running on Pre-G3 PowerMacs too? I would think that there was a fair bit of effort to get 9.2.2 running on, say, a 6100 sometime in the past. The 9.2.2 Finder works fine with a 9.1 system on these Macs so it should be...

Did anyone ever find a hack that would get 9.2.2 to work on older Power Macs and thus sheepshaver? This would be quite useful for use with sheepshaver considering the NetBoot9 disk image freely available from Apple that contains a 9.2.2 system folder. http://support.apple.com/kb/DL1192 I...

Coming in VERRRRY late to the discussion, I would like to add that using some power adapters with excessively high current ratings can damage equipment. Say that you pick up a really cool looking, medieval 5V, 10A power adapter and hook it up to a couple of 7400 series chips for a school...

I wonder if it's possible to chop away an 800 back panel and replace / integrate it with the 7200 back panel? I never knew the these machines had such similar shaped logic boards.
