Are you saying if X value is in mem address Y then the driver will not work with the card? I'm not up to speed on how you would check this, not used the memory monitor on the II or IIgs. Any chance you could write how to check this down, step by step?
Quick update, the SCSI gender changers just arrived, and I put a ZuluSCSI 1.1 into use, as a replacement for the BlueSCSIv2 external model I have been using until now. Luckily they can use the same images, so I used a previous GSOS 6.0.4 image to boot into, and.... no change, same complaint...
I have a ZuluSCSI, but it uses a 50 pin internal SCSI connector. I DO now have an adapter that goes from 25pin external to 50 pin internal. Only issue is, that adapters 25pin is female, and it needs to be male to connect to the A2SCSI card. I have some gender changers ordered from Amazon. Those...
I'm agree, there may be some kind of mis-configuration between my card and the GGLabs design. I have a feeling it could be the ROM, maybe it has been incorrectly written with the original Apple SCSI ROM. The GGLabs product page states it has altered the original ROM slightly to remove its ID...
I'm beginning to think there is some ROM issue with my card. I was wondering if you happen to have an EPROM reader/writer? If so, would it be possible to read the data from your working cards ROM and post it here? What also would really help is a decent, well lit, 4k photo of the chip side of a...
OK I have tried to walk this walk. To do it...
I got a 5.0.4 GSOS boot disk, and removed some fonts and drivers from it to make space.
Then I installed the GGLabs (patched) SCSI drivers onto that floppy.
Then I copied Advanced Disk Tools from its 2nd Utils disk onto the boot disk, using...
Well, I've tried using the stock SCSI drivers, in various version of GSOS AND also the drivers directly linked to on their product page. Which is
https://gglabs.us/sites/gglabs.us/files/a2scsi_drv.zip
And the same outcome, GSOS cannot use the supplied drivers with the card. I have reached out to...
Yes, sadly, I cant get to that position yet. Right now, I can ONLY boot from a single ProDos partition on my BlueSCSI drive, even if it has more they wont mount. And ANY other drives I have on the SD card DO NOT appear on the desktop. The Advanced Disk Tools App refuses to touch even the boot...
Hey, so yeah, I did try installing the GSOS SCSI drivers using the ALL option and no dice. I also tried installing GSOS fresh, and then ONLY installing the drivers that GGLabs list on the product page. Same result, its as if the card has a fault on it, which for some bizarre reason just will NOT...
Hey, thanks for the feedback. Yes, the firmware is updated, well its using 8th December 2024, which I believe is the last non experimental version.
An update on the issue, and yes, its certainly VOODOO
I found 3x .hda images on the BlueSCSI site, one is a basic install of GSOS 6.0.1, one is a...
This is a re-post from Apple Fritter forums, as this is a pretty specific problem, I thought it best to spread my net wider...
Hey, I am relatively new to the Apple IIgs, and in my enthusiasm to get it up to the level of an Amiga 2000, I decided to buy a SCSI card, and ideally install GSOS to a...
Here is a video of the issue in action...
https://www.dropbox.com/scl/fi/g3nk14f9u4dyofvu25a9h/Demo_Vertical_Lines_Issue.mov?rlkey=ktmla4154844nw3cg8ddzeje5&e=1&st=b5gvfrlf&dl=0
It shows the vertical line in most of the display modes. Hope this helps diagnose the issue!
Yes, I'm sure, I have an apple RGB monitor, came with it, same issue, though it does look nicer. The rough scaling in the video is because of a VGA adapter + VGA to HMDI adapter needed to record the video.
Hey, I have a LC475 and it has issue with its display. Predominantly it has vertical lines visible.
See this video here,

Where, not only can the lines be seen on the Mac desktop and windows, but also in Apple IIe graphics (IIe Card)...
Thanks for sharing, yep those look great. I found it interesting that my Mac to VGA to VGA/HDMI adapter worked for the Apple II mode. Its not VGA right? But still it came through, and made the video possible. My biggest problem now, is fixing me LC475's display. I managed to tweak my chaptures...
VERY interesting, I had assumed something more locked down was being used. Otherwise, why limit yourself to JUST those particular colours and also the repetition of black/white, with the high bit set. TBH I was not that disapointed by the colour choice, rather JUST the repitition of black/white...
