    Testers Needed: Modified ROM for LC475/Q605

    I see the post on the 68K forum, I was asking (likely poorly worded) the same thing as @zigzagjoe. Just change one variable at a time for a comparison. Using the v092 ROM, with everything else the same, and the CPU at the default 25MHz, changing the RAM timings from 80ns to 60ns shows this...

    Testers Needed: Modified ROM for LC475/Q605

    Very Interesting! Am I interpreting correctly, the improvement shown in the graphs is both going from 25MHz to 40MHz and enabling 60ns RAM access? If so, it would be awesome to see the difference without the overclock and just with the overclock.

    System Software for Color Classic and Color Classic II

    "System Enabler 403" for the 520 and 550 will work. I believe the Color Classic II logic board is basically the same as the one used in the 550. These sites seems to confirm that: https://powercc.org/mystic/ https://lowendmac.com/1993/mac-colour-classic-ii/ Half the fun is figuring this stuff...

    System Software for Color Classic and Color Classic II

    A plain 7.1 install will work on Macs that came out before it was released but you need machine specific "Enablers" in your System Folder for later Macs. Some good info on this (and Enabler downloads) here...

    BlueSCSI firmware update issue

    I've seen this half way through copying error with my Windows 11 Pro bench PC and in all cases the update was actually successful. I'd suggest turning off debug and looking at your log.txt again to confirm the firmware it is booting with.

    SuperMac Marketing Tool Kit Vol. 1

    Just posted to Macintosh Garden: https://macintoshgarden.org/apps/supermac-marketing-tool-kit-vol-1 Looks like some neat stuff although you need period (1991) compatible versions of Pagemaker, Persuasion, etc. to open some of the contents.

    BlueSCSI v2 Pico - Low cost, open hardware, fast SCSI device!

    I had an unassembled BlueSCSI v2 PowerBook / 2.5 Inch SCSI 2022.11b kit that I finally got around to building (it's going to go in a PowerBook 165c I'm fixing up). I put in a Pico W in anticipation of using the DanaPORT WiFi feature and also did the "wake from sleep fix" for older BlueSCSI...

    File Sharing through BlueSCSI

    'Ethernet' vs. 'Alternate Ethernet' is not your problem here, the name is different just because the Ethernet driver is different. You mention on all 3 machines you are using Open Transport and that "TCP/IP" control panel is set to 'Ethernet' for the Power Mac 6500, an LC475 and 'Alternate...

    BlueSCSI v2 Pico - Low cost, open hardware, fast SCSI device!

    I was trying to figure out a drive for my newly acquired Power Computing PowerCenter Pro, which happens to have shipped with a Ultra/20Mb SCSI Adaptec 2930 SCSI PCI card... Looks like I need to pick up another BlueSCSI! I have a Sonnet ATA66 PCI card in my PM 7300 sporting a PATA SSD but...

    Card Retainer Baffle - PM 7600 / G3 - photo request

    FYI - I also have a 7200 chassis and its Card Retainer Baffle looks to be identical to my 7300. I think that covers the pre-G3 desktops that used that general form factor, so I'm guessing that means the 7200, 7500, 7600, 7300 (in chronological order) used the same style. It seems when they got...
