This is all of the paperwork and documentation that comes with the AppleCAT. Information such as how to hook up and diagnose computers is provided (in color).

Hello everyone I don't know if most of you have heard of the Apple C.A.T. Diagnostic Tool, it was issued form Apple in the mid to late 80's and was used to diagnose and fix computers such as the Macintosh Portable, 128k, 512k(e), Plus, SE, SE/30, ii, iix, iicx, and iici (there may be more I am...

I think what you've added about that RAM is interesting I'll have to look and see if they hid anything underneath the boards as well.

128k has a fat Mac mod hence the wires going everywhere. The Plus and 512k are stock (oddly enough never seen a ceramic 68k CPU on a 512k).

Not my best work :ROFLMAO:

Yeah figured it was worth a shot, I'll only be using this for my Macs.

Here’s a very bad quality YouTube video I just uploaded, it’s still processing better formats so hence the bad quality now and excuse the background noise.

Same model as yours, want HDMI out of my apple ii plus so I got an AV to VGA adapter, I plan to use mostly Macs (I still need a DB15 TO VGA if anyone has one please PM me let’s work out a trade) here’s what I tried for my Apple ii and it didn’t work:

Extron arrived, got the HDMI variant doesnt like my component to VGA adapter apparently but hey of db15 works I’ll be happy.

It turned out to be $700+ don’t worry @retr01 we I’ve a new one coming up.

That's 2 we have from you already in the works, thank you!

Anyone need a spare but doesn't want to order 20,000 components?

Crazy news everyone, @splorp has sent me two oddly labeled TechStep ROMs. I assumed they were prototype ROMs maybe PVT or late development, well nope definitely early or middle of the road production you can see hand soldered components and bodge wires. I've included photos below and included...

It’s in the works😉

thank you @retr01

Funny I actually reflowed the EGRET twice and somehow that fixed it

Alright need some ideas from everyone

I also advise you take a look at the VGA mod to get a better resolution out of the board swap.

I think this is a cool idea look forward to PM

So here's my thoughts category ranks such as different levels in increments of 5 where you get a badges for helping others. This could be applied in both diagnosing issues, resolving issues, new creations of the community, etc. These are just a few ideas, what are your thoughts @retr01?
