Downgrading the G4

I could no longer take the pure performance of my G4 PowerMac, so when I saw this old ATI card in　the Junk section of the local Hard-Off for 100円, I had to pick it up.

Before the down-grade, I was running a hacked Nvidia GeForce, which replaced the original ATI (that I still have). 

Firstly I was surprised that the card actually works. I guess I (or it) was lucky that it was only in the Junk bin without protection for long.

Test-setup:

• MacOS 10.4.11 (Tiger)
• Cinebench 2003
• GeekBench3

Results

Geekbench results where identical, since it doesn't test GPU in that version.

Cinebench, impact was high:

 But hey, I don't keep that thing around for performance computing.

As a bonus, my MacOS 9.2 partition is now usable again. I could not for the love of god get it to work with the Geforce.

So finally I can enjoy errors like this again :-)

I came across this random computer. It didn't (and still doesn't) work, but I thought I take it apart to figure out what it might be.

 

I suspected it might be some sort of XT clone, and indeed, inside is a M80C86 from OKI. Isn't "M"for "military"? Looking at things, this looks like a clone of a Tandy laptop (which itself was a clone of the IBM).

I took this baby apart, because the floppy drives where kind of stuck - they would not take disks. And also I wanted to check for any bios batteries to remove.

Yeah - greetings from 昭和６２年, that thing has been removed.

It came with 2 expansion cards

I was able to get the floppies going, but looking at the age of this thing, it probably wants DD disks, which I currently do not have. Speaking of the floppies, they are not standard - some weird thing going on with the eject button being in the middle.

Also - check out this keyboard. I like that there are even extra Y/N keys - amazing.

The keyboards lower keys where all stuck, but pulling them out and giving them a few days rest seems to have fixed them. The machine is also incredibly clean, seems like it was never really used. Not sure what to do with it though. Unfortunately it does not have a monitor out and even though the display (barely) works, it's not really great for doing anything with.
