    Macintosh 68060 Redux

    That depends on the machine ID as well. Q800 memory timings are even tighter than Q650 as it's tuned for 70ns memory, using the same ROM. (IIRC, if you load an LC475 ROM you get the Q800 timings for both, oddly enough).

    Macintosh 68060 Redux

    Hmmm, good point about later ROMs. Besides the novelty of PiStorm from an engineering perspective, it's not been interesting enough for me to tinker with one in an 030+ so I've never tried to fit one. Given it doesn't drop-into the socket, I bet no one else has either. The Mac being a real...

    Macintosh 68060 Redux

    Even on Amiga I believe PiStorm tracks the program counter to see when the system is running ROM regions that are timing sensitive and slows operation. To my knowledge that's never really been fully worked out on Macs, and unlike Amiga which only has a handful (relatively) of active ROMs due to...

    Macintosh 68060 Redux

    Theoretically the resources can be re-ordered without too much difficulty if someone puts in the effort to write a tool to adjust the various list pointers. It’s certainly doable without too much pain. If so I suspect enough resources could be dropped by sacrificing II-series support. There’s...

    Double socket stack making me laugh. The bottom is just a riser?

    Is anyone successfully emulating a Lisa?

    Run `git apply` in the repo, paste the patch, and press ctrl-d. This is assuming you're on macOS (you can also patch this way on Linux, but the patch here only fixes compatibility for macOS).

    Identify SE/30 video card

    The file is an overdump, or the card only maps the first 2k into memory. It can be parsed if you truncate the file to the first 2048 bytes. It supports 1024x770 at 1-bit.

    What is the technical reason why DDP AppleTalk doesn't work with WiFi?

    It just magically started working for me at some point, I was surprised too. I haven't tried everything but I can browse the network to discover devices and mount AFP over DDP.

    Ubiquiti APs + OpenWRT ethernet router working great here.

    Performance: AsanteFAST versus Farallon EtherFast?

    Today I was doing some research and noticed in a picture the Farallon uses a full duplex chip and I was curious to learn more! So then I found my own thread here...oops. Anyway, they do share pinouts, so I suspect it's a drop in replacement: LAN91C100...

    SuperMac PDQ, Spectrum 8, 24, Thunder ROMs

    I suppose this is good a thread as any: I was poking around the Radius listings on eBay today and realized something curious. The ThunderColor 30/1600 and Thunder IV run the same chipset: Radius 298-0001-01 Radius 298-0002-01 Radius 298-0010-01 The ThunderColor has an extra NEC chip that looks...

    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.
