Now that I have better equipment and some trace repair experience under my belt, I think I'm going to tackle getting this accelerator working again. The consensus a year ago was there's a continuity break somewhere (probably due to leaky cap damage) that's keeping it from seeing a couple of the...

I'm here...got a bit distracted from this though. I liked the structure of these "study groups" though...made me find the time.

Most useful? I guess the print that I "use" the most is the little hook for my headphones that clips onto the edge of my desk.

In related news, my GGLabs SCSI card arrived today, and I had GS/OS booting off a BlueSCSI within 20 minutes :)

@jokker and I went back and forth with a few debug BlueSCSI firmwares he made me trying to figure out what this card is doing. In the process, I discovered that I actually own two of these CMS cards. Both of them were exhibiting the same behavior with the BlueSCSI with all other variables...

Tried a different, known-working BlueSCSI...same behavior. Just ordered the GGLabs SCSI card since it's known to work and term-power will be convenient (y)

Anyone know if 3.5" WOZ support is planned?

You'll probably like this little guy then...CP/M card for an Apple IIc :) Looking forward to trying it out when I get around to restoring my IIc's.

Ya, Eric suggested I make a 32MB ProDOS image with CiderPress...tried that and no change. It has been awhile since I used this BlueSCSI, and I don't have a mac handy that it would be easy to test it with. I tried updating it to the v1.1-20220917 firmware, but that didn't change anything. It...

So I've been trying to get this card working with an external DB25 BlueSCSI in my IIgs and I'm stuck. Keep in mind, I've never used SCSI on an Apple II before. I found the manual for the card here...

Quadra 660av...chassis under the logic board is completely rusted through, and the PDS-to-NuBus adapter was destroyed.

Any news on part 3? :)

Good enough for me.

My 0173-A board does not have the //e connectors (keyboard, etc) installed: Neither does this one: https://www.myoldcomputers.com/museum/computers/appleiigs_woz.htm Here's one with the //e connectors installed, same bodge stuff on the back, and it's a 0173-B...

I see...bodges were done before the board ever left the factory...ROM01 upgrade would have come later. But in a nutshell, the presence of the bodges (and possibly the 'A' board revision?) suggests it started life as a ROM0 board? That would then suggest that I have a "real" Woz machine instead...

Hah, I was about to post asking "what are these bodges on the back of my IIgs board" when I saw this. I just found that my board has identical modifications: https://tinkerdifferent.com/threads/is-this-iigs-board-a-rom0-that-was-upgraded.2043/

I've had a IIgs "Woz" edition for awhile, and I finally took it apart to recap and retrobrite. It's always reported ROM1 when booting, so I kind of assumed that someone had just put the Woz top on a non-Woz machine. However, when I got it apart, I noticed a few things: The logic board is the...

I don't. I just have the power workstation and a few of their accelerators.

Oh snap, I started to remove the drive's PSU to recap it (why not?)...maybe I shouldn't turn this thing back on :LOL:

Anyone have experience using SCSI hard drives with an Apple II? I have yet to ever use a hard drive of any kind with any of my Apple II's, so I have no clue where to start with that, but I found this CMS SCSI card in one of my IIgs's: I also have this CMS model SD30U external SCSI drive...
