As per the GS/OS source, the following ROM detection is done to determine if an "old" (not High Speed) Apple SCSI card is installed. It then checks code in the I/O select space at $Cn00 thru $Cn57 where n = slot number. It points to bank $00 then checks $C8XX for $02 (this is a check for the...

Make sure both the modified "SCSI.Manager" and "SCSIHD.Driver" files are in the "DRIVERS" folder of the System Folder on your startup disk.

Do not install the driver. You should be able to partition and access a drive from GS/OS without it. I suspect that the ROM on the card differs from what the patched driver has in it. Its one of the pitfalls of modifying a design.

I haven't played with the HFS driver in Linux, but I would have thought they would have figured out resource fork handling. Pretty straight forward to present them to the OS as "._" files I'd think.

FWIW, here is the original end user manual for the card: https://mirrors.apple2.org.za/ftp.apple.asimov.net/documentation/hardware/storage/disks/AppleIISCSICard.pdf Apple's description for setting the SCSI ID is pretty terrible. They call it "priority" and say nothing about it needing the ID to...

I don't know what GGLabs changed on the card that required a change in the driver. Apple's cards are pretty straight forward, they expect drives to be partitioned with a valid Apple Partition Map. I would try the following: -Install the SCSI card in Slot 7. -Set a blank (zeroed out) 40MB image...

The "Wings" A/V card supports an external TV tuner adapter. ATI sold it as an option for their cards (ATI XClaimTV) and connects via the S-Video input with extra pins. I have one of these boxes as it came with my XClaimVR 128 card. The manual clearly states that the Beige G3 is supported...

As this is right up their alley, you may want to post about this over on the SHMUPS hardware forum: https://shmups.system11.org/viewforum.php?f=6

Case closed, move on.

That full size crystal with the bent legs IS the original part shipped with the card. I was able to push my card to 12Mhz. Anything above that was a crap shoot, but I haven't upgraded the power supply yet.

6.25Mhz points to an earlier card I think. The GAL set installed is a good indication as well (more rev A parts = earlier card). A better date would be the ROM revision if you had the original 8k cache card. The 32k cache upgrade was offered separate and usually came with v1.8. What GALs is RE...

You should be able to lever is out slowly with a pick or hook style tool. At least that is what I did on my card, but I think mine has a more traditional style PLCC socket with slots on the sides for the extractor tools. I would be prepared to replace the whole socket though because the...

None of this is a surprise. Tons of "green screen" applications are in use today. I use a TN3270 session daily at work along with many other IBM CICS applications that were, ahem, "upgraded" to a web interface. A well designed 3270 or 5250 terminal application is WAY easier to work when than a...

Surprised Apple didn't have a Twinax solution as that was the most common way to connect 5250 terminals at the time. Today all this stuff is obsolete with the advent of TN5250 gateways so not surprised this stuff got tossed. The client performance quoted is pretty terrible. These are block...
