    MDD G4: $70 a good price?

    The Firewire 800 models are mostly OS X only. The dual 867Mhz machines can run OS 9.2.2.
  2. I haven't looked, but the 040 PDS connector looks very similar to the connector used on the Amiga 3000/4000 CPU cards.... which are available.
  3. The Zorro II bus on the Amiga is pretty much a direct pinout of the 68000 (24-bit address bus) plus a bus arbitration chip called Buster to handle DMA. Zorro III upgraded this to 32-bits all around and expects a 68030 or 68040.
  4. It'll also pass thru any content coming from the VGA port to HDMI untouched with no upscaling (dumb ADC), it can also do 2x scaling on 480p sources (so 640x480 is outputting 1280x960). Handy if you have a TV or monitor without a VGA port. The bigger issue with 16:9 modes is Nubus era hardware generally doesn't have enough power to drive 1280x720 or 1920x1080 modes natively. Those that do generally don't have the resolution presets in their drivers.
  5. The Performa 600 had the creased CD bezel with a sticker under the slot with various logos for Photo CD, etc. Both the Performa 600 and IIvx that I had came with this style. Did the Quadra/Centris 650 come with a caddy loading drive, or were they all tray drives? Its possible they face lifted the caddy faceflate for the Q650 and somehow that plate landed up on a IIvx at a later date when a CD-ROM was added. PM7100s were universally caddy drive and manual inject floppy, but Quadra/Centris era was a mix between caddy/tray CD-ROMs and the auto/manual inject floppies. Then there is that mutant PM6100 I created with a caddy loading CD-ROM+plate from a Q610.

    Dual / Multi LC PDS slot

    I'm assuming the need to tap the $E IRQ is because the driver doesn't support anything else? The IIsi PDS does have other IRQ lines available (that is if they are electronically compatible with what the /SLOTIRQ.E pin in a LC outputs).

    Dual / Multi LC PDS slot

    I am not too familiar with NuBus, but if it uses memory mapped I/O, its likely the slot spaces are hard wired on the logic board (ID0 to 3 pins) eliminating the need for address decoders like ISA has (similar to how the Apple II's slots are mapped). PDSes aren't so restrictive, its likely you can add an address line decoder for additional "slots" besides $E. Also, some ethernet chips may require an interrupt request line. Others like the cs8900a can be run in polling mode, which has a performance hit.

    Dual / Multi LC PDS slot

    MicroMac had a multi-LC PDS adapter too. You can likely share interrupts similar to how two serial ports piggybacked on IRQ 3 or 4 on PCs. NICs generally don't use interrupts either. Looking at the pinout, there are additional SLOTIRQ D and C pins on the 32-bit LCIII version of the slot but none of these upgrades appear to have taken advantage of this. Overall its a fairly "dumb" slot since its supposed to be a mostly direct pinout from the CPU, similar to PC's ISA or Amiga's Zorro (although both of those also have DMA controllers).
  10. One may also want to consider the generic AdobePS printer driver for System 7 as well. It supports PPDs and even color printing out of the box.

    How to make GS/OS boot disks?

    ResEdit should be able to change the filetype/creator on the files. http://vintagemacmuseum.com/macintosh-type-and-creator-codes/

    Repair: AsanteTalk or MicroAsantePrint?

    See notes here about the AsanteTalk, these boxes are apparently pretty quirky: http://ivanx.com/a2server/a2server_lan.html Not nearly as bad as setting up a Fastpath 4 or 5 from scratch though!

    How to make GS/OS boot disks?

    Bernie 2.6 should be able to mount them, although like most programs in classic MacOS, you likely need to add the proper filetype/creator to the files.

    Trouble Installing GS/OS 6.0.1

    Your picture is a bit blurry, but I already see the problem. The Rev A AE GS-RAM card is NOT DMA compatible. Only the Rev E GS-RAM is fully DMA compatible as per the RamFAST installation manual (I know its not an Apple card manual, but these DMA problems apply to ALL cards). You'll forego 512k of extra RAM, but the Apple 1MB card is fully DMA compatible. Applied Engineering did some really funky designs on their cards to get those oddball amounts and they tend to break DMA. My GS-RAM Plus (6MB card) has similar compatibility problems. Its DMA safe for the first 4MB, but the card won't work in a ROM 3 machine without a GAL swapped out!

    Trouble Installing GS/OS 6.0.1

    Create partitions that are slightly smaller than 32MB. I know earlier RamFAST SCSI cards had weird bugs with partitions that were the max 32MB, don't know about the Apple ones.

    Orange Micro NuBus PC Card - Need Help

    The Cirrus Logic chip is the PCMCIA controller. Note that it is impossible to make a 100% Sound Blaster compatible PC Card since the standard lacks any sort of DMA pins.

    Orange Micro NuBus PC Card - Need Help

    The Micron DRAM chips directly below the WDC chip (the SVGA adapter) appear to be the VRAM.

    Classic Mac OS will survive Y2038 (and maybe longer)

    The UNIX epoch problem has already been a problem and solved in many systems. The end date for 30 year mortgages for instance......

    Newest conquest: Apple IIc

    Remember to check the ROM revision. type PRINT PEEK(64447) from a BASIC prompt. If its anything but "255" you can use a FloppyEmu in Smartport mode for storage. Revisions 3 and 4 have the memory expansion slot and the model number on the bottom of the case will be A2S4100 vs. A2S4000.

    Millenium bug after 20 years?

    Heh, Apple must have known the Lisa was doomed to fail. That machine's clock can't even be set past 1995.

    Insane SCSI to FW prices

    Just be very careful with those Toshiba XM series tray loaders. The motorized eject mechanism is very fragile and can induce rage when it breaks. http://www.vcfed.org/forum/showthread.php?40455-Toshiba-SCSI-CD-ROM-Drives The computer store I used to work at sold a bunch of machines with the IDE version of these drives, and within a year the vast majority were replaced since they refused to eject the tray.

    Insane SCSI to FW prices

    FWIW, Plextor SCSI drives can be jumpered to 512 or 2048 byte blocks. Regarding high prices of FW to SCSI bridges. They were a transition adapter that outlived its usefulness. Its not surprising that they didn't hang around long.... just enough until folks replaced their SCSI stuff with Firewire or USB and even than it was only really targeted at Mac users.

    How to make disks for a IIGS?

    At that point, I would just get ADTPro setup and create disks that way. Yes, it requires a serial cable, but the program makes everything SOOOO much easier then the Disk Copy floppy shuffle on an old Mac.

    How to make disks for a IIGS?

    A FloppyEmu is a good investment. This is coming from someone that has both a SCSI card in a IIgs and a CFFA3000.
  25. The Amazon reviews of the Radeon 9200 Mac Edition mention that the DVI port doesn't work on HDMI TVs back in 2006: https://www.amazon.com/ATI-Radeon-9200-Video-100-436011/dp/B0002F8MJY The oldest DVI equipped card I have is a 1999 Matrox Marvel G400-TV with the official DVI daughter card add-on. Granted its in a PC and not made by ATI, I should see if it works with HDMI TVs.
