Interesting - I haven't seen that issue before. Do you have less than 4MB of RAM? I should add a warning to my website as well.

3.5 might be a bit new, 3.2 is probably more period. But don't worry (I realise it isn't generally trivial to throw software on old machines). I'll leave you in peace to play Prince of Persia on your SE :)

That's interesting that it was such a small difference. I don't have a 68881 to compare, but old publicity materials claim double the speed or there about if I remember correctly. 12% is... a lot less! I guess it makes more sense. Silly question, but since you have System 7.x installed, could...

I realised after my post that System Info doesn't actually work in System 6, doh! Anyway, pretty serious speed increases. The graphics must be amazing. Do you have a PGA 68882 in anything? They should be a direct swap for the 68881, but give you a good bump to the FPU performance. It would be...

I don't know a huge amount about the SuperMac cards - they look pretty cool. I'd be interested to see some benchmarks if you get a chance (<cough>Norton System Info</cough>). Regarding this thread and other projects - when you're working on your own or in a small team on something like this it...

You don't even need a new oscillator. I really need to write the method up more carefully, but for what it is worth : https://68kmla.org/bb/index.php?threads/new-awesome-and-easy-way-to-bump-a-wombat-to-40mhz.46941/ In short - a blob of solder will get a 33MHz Q650 to run at 40MHz, and if you...

Excellent, thank you! I'll update the page. I'd like to get a 4400 some time, just because of their weird-ness. I keep being tempted by bare boards on eBay. :)

341-0741 is a ROM not a Cache. The machine will boot with just a ROM installed, but it wont boot with just an L2 Cache installed. They both have the same connector and you can actually swap their positions, although if you look at the silkscreen, one slot says Cache and the other says ROM.

I've only messed with the Stuffit InstallerMaker installer. I haven't looked at the VISE one.

I just restarted in 7.6.1 and ran the exact same install process and the application didn't install (just the help file). So I grabbed the Appearance Extension (I was too lazy to grab the Control Panel, it isn't needed), and it still didn't install... In conclusion, it seems likely it is...

Well, I just tried installing it in 68k QEMU (a Quadra 800 running 8.1) and it just installed I think. There is what I got (attached).

I had a quick look at InstallerMaker files and I think... By default, the files are compressed using the StuffIt format. They're stored in the data fork Based on this, I tried copying the data fork from an installer of my own into a new file formatted as a .sit, just on the off chance...

Personally I wouldn't got past 8.6 for my only boot. 9.x is less stable on beige macs than it is on iMacs and other later macs, plus it takes forever to boot... and uses loads of RAM... 9.2.2 needs hacks to install on a beige mac, 9.1 is the maximum that just installs. I'd just install 8.1 or...

It will go all the way to 9.1, or 9.2.2 with a bit of messing. You struggle to get OSX on them because they have low maximum RAM limits. I said 8.1 because it is the next "good" OS on from 7.6.1. Plus it's memory requirements are pretty similar to 7.6.1 and so without finding out how much RAM...

If you just update it to Mac OS 8.1 it will be fine again. The cheapest way to get ethernet is a PCI ethernet card. There are some common cheap models that work in old macs, for example, ones based around the RTL8139 or RTL8169S chip. The mac drivers can be found here ...

Ah, now that is an issue I know. The issue is that the filesystem changed a little between System 6 and System 7 - your System 6 is trying to rebuild the structure of the filesystem on the disk formatted for newer OSes, but the disk is locked, so it is failing. For CDs this was an issue with...

It isn't a period issue, this is a BlueSCSI thing. Effectively it is presenting something as a locked disk that isn't a disk, so the OS is seeing something incorrectly formatted, that it can't correct. You can force things to not mount... but this absolutely needs to be sorted from the SD card...

Sounds like there is a/are file/s on the card that it is trying to recognise as an image. Check the log file to see what files it is trying to mount as disk images. If that isn't possible for some reason (I don't have a bluescsi) remove any files you have added other than the disk images you...

That issue is entirely to do with the disk image, not PRAM. PRAM only holds info on which device to boot related to this. I recommend starting from a stock bootable image and working from there. It just sounds like the image is mounting locked for some reason, but that is a bit of a weird...

Yes, confirmed that you need to install 32bit QuickDraw. Little brochure for the card (and its alternative that is identical except that it ships with 1MB pre-soldered). Yours is the 4.8, but upgraded to the 8.24 due to the VRAM SIMMs.
