Got another twinax card up and running. This time it was the IDEAcomm SE-5251 card running IDEAcomm mac.

Just wanted to tag you to make sure you see my update about software.

Big update for Twinax on the Mac. I reached out to the webmaster at tryas400 and he pointed me to this https://macintoshgarden.org/apps/apple-cdsn-computers-connectivity-demonstration-and-support-network-reference-cd It has the Andrew and IDEA software on the cd. Was able to successfully...

I found a reddit post from two years ago where someone had one new in box (the SE version at that), but when bitsavers asked him about it last year for archiving purposes there was no reply. I wish whoever he sold that boxed card to had archived, but I haven't found anything else out there on this.

You have a copy of the MacMidrange program? Any chance you could help me out with finding a copy? I have on its way a IDEAComm SE-5251 card and their 5250 software seems lost to time, so I wanted to see if that program might detect this card.

I've been somewhat out of the game for a little bit, and recently just started messing around with the vintage Macs again. Last night saw a listing on Facebook marketplace and picked them up this morning. The seller had pictures of them working, but so far nothing powers on for me. Caps are...

Checked a 520 and 550 I had and they are also installed backwards. I know that at least some of these are original drives on original sleds for the machines. Here’s a picture of what I mean, what looks like a release tab is at the front of the drive not the back.

I took apart another 575 this morning and it was using the 815-0446 REV C. The interesting thing I found was that this one was installed backwards compared to how it should be and it doesn't fit the machine if its installed in the correct direction. You have sent me on quite the goose chase haha

Scratch all that I just pulled the drive out of my 575 that I have handy and it has 815-0446 REV B in it. So I don't know when they switched parts compared to the service source but I am fairly certain this one is original from the machine.

Looks like that is a carrier for a power Mac. I think the part number you want is 922-0621from the service source manual for the 520, 550, and 575. Ive found some sites that listed both part numbers together when they were selling them, but OWC has the 922 part number and shows 4 in stock for...

Quite a while ago I pulled the board out of mine and just use the RCA inputs since I didn't really have use for the coax connection anyway and recapping isn't going to happen anytime soon. It will still work in the tv mode using the RCA without the tuner board in the system.

Ok so the printing says CSA (or could be C3A) 12.0MT then it looks like a symbol followed by a capital F. There is no printing on the other side. Here is a zoomed photo:

Here is a picture of the back if you needed it.

The software is a control panel called TV setup. This was another post where we were talking about the TV software: https://68kmla.org/bb/index.php?threads/macintosh-tv-tuner-software-drivers.4668/#post-52712 Here is a link to the software...

And that would be what you didn't want to see while opening it up.
