    Radius Rocket 32-bit addressing issue on a Macintosh IIX

    The March 1993 Rocket compatibility guide says it was tested with Connectix MODE32 1.02 and 1.2 and requires RadiusWare 1.3 or later.

    ROM Fiend: A DeclROM, Extended DeclROM, and System ROM parser

    As a tree? Sadly no. You can copy individual property values, or the data sections they point to and export that way. That and highlighting spans in the hex are really features Hex Fiend is lacking.

    Testers Needed: Modified ROM for LC475/Q605

    Neat! From the overclocking thread there is likely a major bottleneck on ethernet timing, at least on some Quadra's. They seem to hang forever while booting the OS when pushed too fast, hopefully just due to insufficient waits and not bus instability. Unfortunately while there's a driver baked...

    Testers Needed: Modified ROM for LC475/Q605

    It should be totally independent from RAM speed as far as I know. I set it to the fastest with a caymac rom and had no issues. I never did benchmark it though (is there a good toolbox routine benchmark?)

    Testers Needed: Modified ROM for LC475/Q605

    You should also apply the rom speed mod if you haven’t. The default setting is very conservative and will slow ROM operations. The ROM SIMMs can all do better.

    MacTuner 2.1.5 on 68k?

    Yeah, you need 40 to really fly. Whereby fly I mean "play MP3s even though the rest of the computer is nearly frozen". If you set it to low quality in the preferences it should handle a 56kbps stream though.

    Superdisk repair?

    I wonder what the dry disk is made of, I imagine it's a pretty common mild abrasive that could be done by hand with the drive open. Mine died awhile back too but I suspect it's an alignment problem. Nonetheless I'm also interested in giving cleaning a try if anyone figures it out.

    The one keyboard to rule them all

    This is like a sad mashup of a IIgs and Sinclair QL but I’ll throw it out there as another keycap option: https://a.co/d/csR0cKk

    Sonic MediaNet drivers

    I have discovered....so very many interesting things! I'm going to do a full writeup highlighting the fascinating parts of this card and it's ecosystem, but in case I don't get to that for awhile, here's a link to a hidden subsection of my site with setup instructions in case anyone else comes...

    Testers Needed: Modified ROM for LC475/Q605

    Since the 475 ROM has (mostly) Q650 compatibility, I can give this a go as well. Do you have any examples of problems without resetting PRAM? I'm curious if some funky behavior I've had in the past matches.

    Skipping the Startup Memory Test

    Interestingly the PPC upgrade cards for Quadras also have this option in their card control panel, even in 7.1.2. I wonder if it controls the same nvram settings.

    Picked up a few macs, don't know where to start

    Definitely worth a dump, though the final LC ROM has a date on it of 9/24/90 and these were made after, so there's a good chance it has the final ROM on it and they're just pre-release burns. Dumping it from a booted OS should be fine, you don't need a ROM programmer. If the checksum is...

    Picked up a few macs, don't know where to start

    Some of those SGI machines are really strange about nvram as well. My O2 will not boot if the battery has died as it's unable to detect scrambled nvram and wipe it. Not sure if the Indy is the same, but if it is, there's a "recovery" jumper on the board which you'll need to set or it won't even...

    The one keyboard to rule them all

    I like the third picture that clearly illustrates "these do not work on older Keychron keyboards" a lesson I have also learned the hard way.

    $5 is....significantly more reasonable. I really yearn for the chiclets though.

    Link? I've got a set of these for low profiles which are IIgs-like, but they're kinda expensive for the quality: https://knob.design/keyset

    Sonic MediaNet drivers

    I determined I just needed the latest version of ShrinkWrap (3.x) to unpack the 5.2.1 image. Fortunately it contains MediaNet 1.6.1! I'll give it a go and make another post if there's anything interesting with this card.
