I want to go to here; this is the future they stole from us.

Seems I don't quite understand how the Apple II GCR decoding works. I capture a sector of data, after demapping and un-xoring, the value at 0x55 makes no sense (highlighted in second image). It’s 0x20 which has a bit set in what I thought were unused bits. Checksum matches. After denibblizing the data looks ok, it's Track 17/Sector 0 of a DOS 3.3 catalog.

What am I doing wrong?

Mac users of Mastodon, I'm sure at least one of you has had this problem before and knows how to solve it. I have an ImageWriter II and an iBook G3 Snow (with Mac OS 9). How do I connect the printer to the Mac?

Hey Fediverse, hoping someone can help with this. I’m trying to re-home a #Macintosh Performa 550. It’s in pretty good shape, turns on, usable, mouse and keyboard included. Please boost if you think you might know someone interested. Tagging the #Apple #vintagecomputing here as well. I’m in the greater #Boston area but willing to ship if you can cover the cost.

Many moons ago, I owned an #HP #95LX. Now I finally own one again. 🙂 Probably way overpaid for it, but that stuff isn't getting cheaper anytime soon anyway.

🌕🧲 We're always excited when we can add another missing piece of technology to our collection – we already have ferrite core memory, but this is our first example of rope memory. 🤩 According to Wikipedia, this type of memory was used as read-only memory (ROM) and was a crucial component of the Apollo Guidance Computer (AGC) that landed on the Moon.
