    12" PC Compatibility Card in a Beige G3

    I never even tried to use it from the serial port on the PM4400. But if I did, I would have had to use my Sinclair QL to interact with Open Firmware :-D ! Curious, again, I don't remember OF being too slow on the keyboard. For me the experience was a lot like the Sun boot prompt. Maybe I'm a...

    12" PC Compatibility Card in a Beige G3

    Macs were quite popular in the Amulet Research group at Manchester Uni in the late 1990s. Steve Furber had a Duo 230 which he upgraded to a Duo 270c or 280c, but my supervisor, Doug Edwards bought a PowerMac 7200/75/16MB (or maybe 90) in late 1996, a bit before I bought my PM4400/160/32MB. So...

    cozyMIDI - new app that plays std midi files (68k)

    Apologies, I wasn't thinking of pushing for B&W G3 support, I was just excited at the possibility of hacking an actual serial modem port on my B&W G3. I'll try and stay on topic!

    cozyMIDI - new app that plays std midi files (68k)

    Aaaah. So, the internal modem architecture is: SCC(part of ASIC) ---> ActualTracesOnLogicBoard ----> InternalModemConnector ----> ModemIC ----> Modem Port I had thought it was something like: ASICParallelInterface ---> ActualTracesOnLogicBoard ---->InternalModemConnector ----> ModemIC ---->...

    cozyMIDI - new app that plays std midi files (68k)

    Does that mean the SCC on a B&W G3 is somehow accessible, maybe via some pads on the logic board? That is, I understand the earliest iMacs had some legacy internal peripherals and connectors and the B&W G3s still have ADB. Does that mean there's other legacy hardware on them?

    upgrading the ibook clamshell's L2 cache to 1MB

    Hi @obsolete ( @croissantking, @Phipli ) I'm hoping to get back to experimenting with desoldering SMTs, using a hot air gun. Knowing my level of expertise, I'm pretty likely to pop a TQFP - though I have a lot to practice on and apart from the Intel 80196 MCU I don't mind too much if it's part...

    cozyMIDI - new app that plays std midi files (68k)

    Sorry: preamble! Well done! Looks like you've done an amazing piece of work! I used to have an MT-32, which despite being pre-General MIDI I suppose is an obvious target if the patches are remapped. I also once had a Roland SC-D70, which I bought to go with my Tangerine iBook, but that's also...

    Getting started

    The Plus is about as empty as an SE so there's a reasonable amount of space. However, it doesn't have a fan, so you shouldn't cram too much in! SCSI is supported, but it has no built-in expansion slot, so the only way to expand it is to remove the CPU and mount a daughterboard with the CPU (or...

    Getting started

    OK, so your thread led me to have a look at what Vintage Macs were available on eBay. It's instructive, because as a whole working ones have definitely been getting quite a lot more expensive over the past few years. Picking an SE/30 as a starting point is understandable. It's legendary! But...

    BlueSCSI does not boot Mac SE

    @zefrenchtoon . So, Eric got me to build BlueSCSI from source. I had quite a bit of faff installing the arm-none-eabi gcc tools version 14.2, because homebrew wanted to install gcc 15 and BlueSCSI expects gcc 14. Homebrew also provided links to Arm's toolchain, but only links to 15.2 for macOS...

    PowerBook 540c - Did a thing (OS 8.6)

    So that means the 500 series is architecturally equivalent to a PowerBook 1400, because that's the same as a PB5300? Interesting.

    BlueSCSI does not boot Mac SE

    @zefrenchtoon : I had an answer from a developer. It seems like it's an RP2040 B0 silicon issue. https://github.com/BlueSCSI/BlueSCSI-v2/discussions/384 He's asked me to compile it myself, so I'll need to update the sdk and probably Gcc!

    BlueSCSI does not boot Mac SE

    It's a BlueSCSI v2 desktop that I intend to stick inside a standard SCSI enclosure, which I was doing to begin with. So, the intended chain of connections is: PowerBook1400 => Dock/SCSI adapter => Zip Drive SCSI cable (DB25 at either end) => SCSI Zip Drive => DB25 to Centronics SCSI cable =>...

    BlueSCSI does not boot Mac SE

    Hi @zefrenchtoon ! Thanks for the help thus far. I've looked at both of those issues. I changed my SD card to a 64GB one that matched the speed setting (10). I formatted it with the special formatting tool on my MacBook Air M2, which took ages as it was over a USB 2.0 multi-memory card adapter...

    Pseudo-Mac mini G3

    Oh yes, I practice puns on a daily basis. Mostly on my wife. And she's still with me, though I'm not sure if that says more about her ability to endure than my skill as a punmeister.
