    Radius Rocket Compatibility

    I've got Sound Manager 3.0 with RocketShare on both OS and it seems to work fine. I've been repeatedly confused by that claim, in fact sound seems to work better, so I'm wondering if it got "fixed" somewhere along the way. As for video cards, I've been scratching my head on that one. RadiusWare...

    GemStart Drivers Various Versions

    Not sure why I never thought to check the wayback...here's the 1996 accelerator price list: At the end there: GemStart Universal v 7.1 68030 Accelerator Driver [N] • $35.00 • new • SOFTW-90346 So I assume they commissioned an update from the original author to sell...

    Connectix Compact Virtual releases other than 3.02, 3.0 RC4, and 2.04?

    Hand-in-hand with this, there's late versions of the GemStart accelerator driver here which claims to support most accelerators including the NewLife: https://68kmla.org/bb/index.php?threads/gemstart-drivers-various-versions.44624/post-555321

    Finding FiberTalk: DuPont's AppleTalk-over-Fiber Hardware

    Neat! 1,000 feet really isn't bad. Beats thinnet and 10Base-T, so it's not too shabby really, if your primary need is long runs (connecting campus buildings and such). Seems pretty niche, but it definitely would have found it's uses in large deployments. Never understood why I needed to be able...

    Macintosh IIci DIP32 ROM replacement issues (SST39SF010A)

    Yeah, though they are easier to source and easier to work with, the more modern chips are still out of production in many cases. I've had good luck with used parts from China, though. You could also consider OTP parts, which are just EPROMs without the window. Those tend to have a lot more...

    Macintosh IIci DIP32 ROM replacement issues (SST39SF010A)

    Oops. I posted a guide on replacing these and I didn't realize it needed to be Vcc, specifically...I need to correct that. If anyone notices any other errors here I'd appreciate it so this can be a better reference now that EPROMs are getting harder to source: https://eharmon.net/retro/eproms/...

    Merida System 33MHz...a Mac SE?

    - The Macintosh Do-It-Yourself Upgrade Book I imagine these are pretty rare, apparently they made a bunch of models for B&Ws but also LCs too. Neat!

    Radius Rocket card

    I had the same problem for awhile. Sadly I can't remember exactly how I fixed it but it involved discarding the guest disk a few times and disabling some extensions on the host. I think it's some extension conflict with the AppleTalk magic the Rocket does to bridge disks.

    Q840av gets a make over

    For some reason it never occurred to me a pico PSU can avoid the power supply connector compatibility issues between boards and cases. Obvious in hindsight, and handy!

    Has anyone been able to install MacOS 8.6 or 9.2.2 on a Mac II or Quadra with a PowerPC upgrade card?

    Huh, I'm aware of third party patches that add pre-G3 support for PCI Macs, but I think it always requires hacks.

    NeXTStation Clock Doubler!

    Oooh very nice! My friend has a non-turbo slab I've been wanting to fix up for them... The multiplexor detail is pretty interesting, I wonder how unique that was in 040 designs overall.

    Has anyone been able to install MacOS 8.6 or 9.2.2 on a Mac II or Quadra with a PowerPC upgrade card?

    I have 8.6 in a partition on my Quadra with a PowerPC card. Besides glacial boot times, it honestly doesn't run much worse than 8.1. To get it on there you have to jump through a bunch of hoops with the Sonnet Presto enabler. Not sure that was ever supported for a Iici though. I've read claims...

    Listing of ReMix Logic Board Projects?

    I've been maintaining a list of these (and others) I need to get around publishing. Here's the logic board ones I know of: 128k - https://github.com/RichCini/MacRedux Plus - MacPlus-Reloaded SE - https://github.com/kr239/Macintosh-SE-Reloaded - Logic Board - Macintosh SE Reloaded - Macintosh SE...

    Wombat (650, 800) board overclocking limitations

    I was reading through the 68040 designer's handbook tonight and figured I'd share the reference thermals for future overclockers. Motorola's reference heat sink is a Thermalloy 2338B: https://www.farnell.com/datasheets/94193.pdf It's designed around the E-Z Mount which never really gained...

    Greaseweasel not reading 800k disks?

    I found a Sony MPF920-1 with a June 2001 date in one of my spare PC cases. It seems popular for Greaseweazel and I can confirm that mine works wonderfully for Mac disks. So it seems even fairly late MPF920s work nicely.

    The Unitron 1024 Revealed! Can we emulate it?

    It definitely seems like a much stronger attempt to make it look like they "clean room" engineered the ROM since it has totally unique assets. I think that's also triggering the bug on 4.2+ (5.0+). It seems the "Welcome to Macintosh" screen interferes with their custom splash screen and refuses...
