  1. Those Adtron SCSI-to-CF adapters used an AMD Am186 combined with an off the shelf NCR SCSI chip, some RAM, and a ROM. Basically a x86 PC with SCSI acting as a bridge for the IDE device. It was common to do that before FPGAs became cheap/fast enough to do the job.
  2. It was convenient during the time it was released. I used them quite a bit back in the day. Your choices at the time were: -Serial port connection to the camera. It usually involved a garbage piece of software to transfer the pictures and where did I put that silly cable again? -An expensive card reader connected to a SCSI port or parallel port. Most people didn't have SCSI and parallel port drivers were always wonky. -A fake floppy that you slipped the memory card into and popped into your computer. It usually just worked and you dragged and dropped your images. It would be a few years until USB card readers and cameras that supported USB mass storage would show up (my camera from 2001 was one of the first to have direct connect USB mass storage support).
  3. The Vibra 16 should have OPL3 FM sound onboard. DOS software should detect it at 388h (standard Adlib hardware port for OPL2/3).

    Shiva EtherGate Internet Manager

    Shiva and Cayman later created incompatible standards to tunnel Appletalk over TCP/IP (think VPN for AppleTalk networks). The latest revision of the FastPath software supports the unified TunnelTalk standard intended to interoperate tunnels between FastPath and GatorBoxes, but I don't think Cayman ever got around to implementing it.

    Potential: Promise Ultra 133 to Sonnet Tempo

    If you don't mind sacrificing a Promise card and can get a dump of the Sonnet Mac ROM, you can try cross-flashing it with the PC tool.

    Potential: Promise Ultra 133 to Sonnet Tempo

    The Mac versions usually have a larger EEPROM on them to hold the OpenFirmware ROM, otherwise the rest of the hardware is the same. You can actually pop the Sonnet card into a PC and the Windows driver will recognize the card as a Promise Ultra 133 and use it. You just can't boot off of it or use it in DOS due to not having a PC ROM on it.
  7. The reason newer ATX power supplies have less capacity on the 5V line is that CPU power has long since moved to using voltage regulation from a 12V source. Back in the 68k days, CPUs were still being run directly off the 5V rail.

    FUN CHALLENGE: 2006 iMac in 2019

    Thats...... kinda sad. I still have a Dell Inspiron e1405 laptop that gets used still with a similar CPU. I joked that it wasn't much slower than some new laptops..... turns out I was somewhat right!

    Connecting Apple IIgs to PowerBook 1400c

    If the IIgs is running GS/OS, you can setup an AppleTalk network between the two with just a serial cable. Otherwise you need terminal software to communicate between the two.

    RAM required for DOS card

    It should take the same RAM as the 6100 does. Any 72-pin FPM 70ns SIMM should work. 16MB modules definitely work, don't know if 32 or 64MB modules will.
  11. The ImageWriter LQ emulation in GSport is completely modular. All you'd have to do is write a port monitoring deamon for Linux and pipe the emulator's output to CUPS and run it on something like a RPi.

    Modern printer on old Mac?

    As long as the HP JetDirect server in the printer supports AppleTalk, you can print from ancient Macs and Apple IIgs machines using the LaserWriter driver.

    Modern printer on old Mac?

    Modern inkjets will not support Postscript or PCL at all. The only way around it is using something like a RPi or VM running netatalk + CUPS/Ghostscript to "create" a Postscript printer queue on the network that classic Macs can see. The printer server will convert the Postscript to whatever the printer wants. The Mac itself would need to have Ethernet or a Localtalk bridge.
  14. A few notes. There is no guarantee that the serial port emulation from the DOS card to Mac side will work at all, there may be timing issues with MIDI devices. SoftMPU only works with non-protected mode games since it uses the 486's MMU to port trap writes to an emulated MPU-401 and redirect them. Anything protected mode needs modification directly (very few games can be configured to use a MIDI device on a serial COM port).

    Netatalk SD Card Image?

    A2Server works fine with classic MacOS machines as well since the Apple IIgs and IIe Appletalk stacks are from the same era (AppleShare 3.0), A2Server also includes Samba so Windows machines can access the shares as well.
