I have a 2006 MacBook 1,1 that originally came with OS X 10.4. I'd like to install the original OS on it, however I don't have any of the original CDs.
I've *acquired* (ahem) an ISO of 10.4.5 from archive.org (https://archive.org/search?query=os+x+tiger+intel+10.4.6) and naively dd'ed it to a USB stick. (making sure I got the intel version)
It starts booting but then displays the circle with a diagonal line through it symbol and doesn't go any further.
So, how would I go about restoring this computer to its original OS? It's currently running 10.6.8, and there's no recovery partition on the disk.
If our softwares were optimized, and if the web wasn't bloated, we could have dirt cheap computers. People already do a lot with RPi Pico.
I think the biggest problem is web. With an RP2040 you can do #gopher, #gemini, #email, #paint and #wordprocessing to say the least. A computer based on this could be very useful for schools. I am being tempted to do a startup or try getting a grant.
Has anyone seen a modification like this in a #Sega #MegaCD? What is it supposed to do? My MegaCD is not working I want to know what this is before I remove it and if I may want to restore it once my MegaCD is running again. #retrogaming #retrocomputing #repair #RetroMod

One of the allures of #retro is the sense of disconnect. Removing distractions by using technology that predates the Internet — the Web, at least.
But you didn't have the entire game catalog of who knows how many systems readily available back then. You had just a few games and you focused on those.
Today, those other games out there just waiting to be played are itself a powerful distraction. It's hard to stay focused, but great when it happens.
I don't really understand this 1980s computer magazine cover #retrocomputing #retrogaming
I try to get you a Forth from as far, far away as I can possibly get.

Maybe I get a French Forth on the Thomson TO7 next year. See also

Today on #floppy disk failures, a sector so close to a physical disk defect that I get different data with every read.
This one is a is manufacturing defect of the surface and a c64 that put a sector just on overlapping on the defect

I just ran across this fantastic article that I think really captures the spirit and joy of early home computing, although I came along just a little too late to have experienced it:
I was introduced to this in a post by @scruss on https://retrocomputingforum.com, at https://retrocomputingforum.com/t/remarkable-10-line-basic-programs-chess-basic-interpreter-many-more/4922/3?u=elb in a super interesting thread started by @EdS on the 2025 BASIC 10-liners competition, https://gkanold.wixsite.com/homeputerium/copy-of-games-list-2024.
#retrocomputing is alive and remains fascinating!

After what feels like 2000 years I have finally got myself an egg whisk style keycap puller so I can replace the left arrow key on my C64C with the proper one thanks to @mike. I assume the left arrow key it had is from an Aldi C64 as it has the same style as the breadbin keyboard on my other C64. Not sure how it got on my C64C originally, maybe someone at the Commodore factory wasn't paying attention
