Ah, I was misinformed. That's good to know. Thanks! I found where I got the (incorrect) bit of info about the FDHD ROMs: http://vintagemacworld.com/drives.html All of the other references about using the drive pointed to System 6. I guess it was perhaps because once users got into the...

They journey/challenge has only begun. :b&w: I had already found the Apple PC 5.25 Drive and Apple Scanner (with manuals) before this project started but I assume there will be much more to add and plan for as people offer suggestions. I didn't expect the proper name to be that important...

Ah, that is a very good idea and there is a System 6 driver for it. Anyone have one of these? :wink: Correct. You are correct. The PC Compatibility Drive hardware and the Apple Scanner gave me the idea since neither of them are very happy in a System 7+ world. From what I understand the...

Well, I was hoping that there were more uses for the card. After all, those DSP chips weren't designed for Photoshop, companies just wrote the code to make Photoshop filters use them. I was also hoping there were more uses for the chips in the AV Macs. I do realize that with any specialty...

I hope to make my Mac II an 'ultimate System 6' box. Since System 7+ is so common I would like to focus on finding hardware and software that did not run well or at all with System 7. I know that the Apple Scanner (first version) and PC Compatibility Drive and Card are good places to start...

Hmm. I know that Apple made a QuickDraw accelerator that was a PCI card with no outputs. Was that what that card was? I wish the chips on these cards could be used for the same purpose. :)

Now that would awesome! So adding DSP cards (as long as they use the same type of chip) to a 840AV will add a speed boost? So the apps that are 'DSP aware' are Photoshop (see question below) and Picture Press. Does anyone know of others? I always wondered if anything actually used the DSPs in...

What can be done with a NUBUS DSP card besides speeding up Photoshop? Anything? I've heard that they will speed up JPEG operations. Are there any other operations they can be utilized in?

Indeed. I am aware of the diminishing returns when it comes to cache although I was a little surprised at how diminished it was. :) Then again in the Norton benchmark the actual app is small and I suspect that much of the test code fit in the 256K cache and that going to 512K didn't show...

Are these numbers reversed? I have both of these modules and it looks like the opposite is the case. Ah! Is there a tool that is more reliable (Guage Pro?)? In that case I did see a very small difference in the Norton benchmark but I was surprised at how slight it was. I kindof figured it...

Short version: My PowerMac 6500/275 sees 256K of L2 Cache although a 512K module is installed. Long version: I acquired my PowerMac 6500 some years ago and it has been an awesome machine. Although it is a 275 MHz version it only had a 256K cache module. I'm not sure why, but I wasn't the...

Since Apple used clear USB & power cables on all of the iMac/PowerMac "colored" machines I am sure you have all run into cables where the plastic/rubber turned dark from something in its prior home. How can these cables be cleaned? Or if they turn brown from something in the environment is...

Okay, research suggests it is the GeForce 4Ti 4600 AGP. It just sucks that ADC won't be supported. Apple and their stupid proprietary adapters. > :(

Hi all, What is the fastest OS 9 compatible graphics card that will work in a Sawtooth G4 (AGP 2x)? Thanks

Hi all. I have an LC that has a damaged plastic case. Can it be reliably repaired with superglue? Is there a better way to repair it? Thanks!

Yeah; thanks. I found this site a bit ago and was originally looking for the 'cross-reference' between Apples catalog number (M4849LL/A) and the actual part number on the chip. I finally discovered that it was 820-0754-A. If anyone rummaging through their parts drawer stumbles on one of these...

I suspect the only way to find this out is going to be to try it and see what happens?

Indeed. The 5260 uses a SIMM. :)

Correction: 32K chips

I did discover that the module I thought was a ROM-only was actually a cache module for a different PowerMac. I made the mistake because the cache chips from some Macs are the same size and pin number as the ROM chips on this Mac. I was looking up the specs on each of the chips and found that...
