  1. If you send me one, I could print you a set made of TPU at a reasonable cost. PM me if interested.
  2. Probably. I don't know of any replacements offhand, but Mouser is a good place to start.
  3. Measure the resistance. It's not worth risking the audio circuit over a questionable speaker.
  4. It's not exactly a fair comparison. Macs couldn't paint the entire screen with 320x200 like PCs could. Slow Macs had to either play in a tiny 320x240 window or use pixel doubling, which still had a cost. Unlike pixel doubling, the every-other-row rendering in Duke Nukem 3D actually reduced video bandwidth, speeding up the game significantly. On the other hand, 640x480 meant when Macs got Command & Conquer, four times the battlefield area was visible, making it a far better experience.
  5. Why not run native 68K Doom?
  6. I posted an album of a MacSD installation in a Classic. Like Byte Knight's setup, it uses an SD card extender and RGB LED.

    Classic + MacSD build

    Restoring a Classic with retrobrite, logic and analog board recap, custom air intake and discreet MacSD upgrade. The face and cover of the Classic were brightened with 40V peroxide solution and sunlight. A custom, 3D-printed air box mounts a larger Noctua Redux 80mm fan. Fan RPM is reduced by a string of four 1N4007 diodes. For easy SD card access without removing the Mac's cover, a slot extender is mounted to the analog board, near the picture controls. The first step is cutting an H pattern in the sheet metal with a rotary tool. I bent the ta
  8. Sounds like it needs 512 byte sectors.
  9. Looks good! That's a very smooth retrobrite job.
  10. I had the same hard lockup running HyperCard from that image on my Centris 610 with System 7.5.5. There were no SCSI faults. I used the Centris to copy the contents of that CD image to a 2GB HDD image. I then switched the boot drive in macsd.ini to Realitystorm's 6.0.8 image, put the card in my Classic and the stack ran fine. It appears to be a software issue.
  11. Good to know you've received it.
  12. You are mostly correct. I would not say an LED uses 20mA, but that it tolerates that current. It emits light with far less current, but as you've mentioned, a 1989 LED is less efficient than what is available today. The LED code was overhauled for v0.8.0. Maximum external LED drive is 3.3v through a 220 Ohm resistor at 9.7% duty cycle.
  13. This is not "SCSI2SD for dummies". If features I add to this product conflict with what you think it is or should be, you are mistaken. Most of my customers already had a SCSI to SD solution. I've sold to non-Mac users and will continue to. Don't concern yourself with it. That discussion is best led by people who have actually used the device, or at least bothered to read the documentation before speculating. I'll let you know about a vendor account.
  14. It has crossed my mind. The problem of incorrectly entering filenames, etc remains. I'll add more to the documentation about partitions. For now, here's an example: [2:hdd] ; Map SCSI ID 2 to MBR partition 4 partition=4
  15. Hi Steve. I've been using your 7.5.5 and 6.0.8 images, and they work well. Thanks for putting them together, they are very useful. I have not tried your floppyEMU images. A full drive on the SCSI side is stored as a file on the FAT32 partition on the card, or as an entire raw primary partition on the card. The CD emulation supports cooked images (.iso/.toast/.cdr/etc) and raw .bin images with a CUE or TOC index.
