    Reverse-Engineered ROM sources for Mac 128K, 512K and Plus

    Got it, make sense. Tried to do something similar with Sonnet 4.6 (CC harness as well), it was stuck sometimes on some function calls. (My use case was trying to make it rename a ghidra disassembly output, I managed to have it off by giving it three different disassembly sources), otherwise the...

    Reverse-Engineered ROM sources for Mac 128K, 512K and Plus

    What model did you use ?

    LaserWriter IISC SCSI protocol reversed (for emulator implementation)

    Has anything used it ? I've got the impression it was always some sort of tech demo. By the way the feature has been merged into Snow, it will be available in the next version :)

    Help with srecord for splitting and joining ROMs

    How wide are the 1400cs ROMs ? We were assuming 8bit wide ROMs

    Macintosh Plus mouse button not registering clicks

    Hmmmm... The VIA cannot generate an interrupt on click and you checked the connectivity and the VIA so it isn't a VIA issue. Random idea: the mouse click is probably polled @ VSYNC. Do you have a pulse on pin 40 (CA1) ? Does the IRQ line kinda follow on pin 21 ? If yes follow the IRQ to TSG...

    LaserWriter IISC SCSI protocol reversed (for emulator implementation)

    Thank you! It was worth it. People are already working with it There is a Snow PR as well. Thanks! KB030514 is the one I remembered. Plenty of other info at this archive... like this driver was created for System 4.3. Might explain some of the spaghetti code

    LaserWriter IISC SCSI protocol reversed (for emulator implementation)

    Thank you, very much appreciated I've tested three of them for this work just to double there isn't any obvious differences: - LaserWriter IISC, (from a 6.0.5) - Personal LW SC 7.0.1, which is a standalone floppy - Personal LaserWriter SC, from 7.5.0 (actual version 7.0.1 as well) Starting...

    Phoenix: Open-Source NuBus FPGA Accelerator for 68040 Macs

    Repo is giving me a 404. Was that moved somewhere or is it GitHub aiming for 80% uptime ?

    LaserWriter IISC SCSI protocol reversed (for emulator implementation)

    Adding more info. Typical sequence A typical printing sequence will look like below. Here is a the driver printing a SimpleText file with the following content: INQUIRY [12 00 00 00 05 00] INQUIRY ⇾ DataIn [02 00 … FE 20 27 20 FF] INQUIRY [12 00 00 00 24 00] INQUIRY ⇾ DataIn [02 00 … FE 20 27...

    LaserWriter IISC SCSI protocol reversed (for emulator implementation)

    They did try at some point with the NT board, but it was by emulating the controller board. Both boards differs in significant ways (IISC being SCSI + "QuickDraw", NT being Serial + Postscript for a start), but will share unsorted hardware notes if needed. (I'm stuck at recreating the HAL...

    Rominator not working?

    Looks like you did a lot of testing. Do you have OG ROMs ?

    LaserWriter IISC SCSI protocol reversed (for emulator implementation)

    Hello everyone, Got sidetracked since a few month, ended up doing this... Decoded most of the LaserWriter IISC SCSI protocol and figured I should post it here, it's probably interesting for the Snow or PiSCSI team (poke @slipperygrey) I do have a complete Snow implementation as well, please...
