I'm pleased to announce a new device for the Macintosh community. This is the result of almost a year of work during the big pandemic.
This work was inspired by @cheesestraws Joystick thread, @Kai Robinson tinkering the SE ADB Chip, and the Space Gray Magic Mouse 2 which does...
I needed this to be done for a R&D project, so in case it's useful for someone else, I'm posting my notes here
The PB5xx series have two 16 pins connector for the keyboard. They are standard 1mm pitch 16 pins ribbon connectors.
Here is a picture of the PCB below the metallic shield...
I've been asked to post this here on IRC so there it is. A lot of PSUs from this era are bad quality and difficult to repair (if possible at all). One of the worsts is the Astec AA15830 (Apple P/ 699-0392)
One of the solution is to use the excellent adapter board by @blusnowkitty and...
One item on my todo list was to benchmark Apple NuBus A/ROSE Ethernet card. A/ROSE is a small Operating System that that runs on some NuBus cards. A/ROSE NuBus cards have their on 68k CPU (usually a 68000 @ 10 MHz) that should offload the main CPU on a Mac II.
This is a little bit of a blog post, if this is more suited to "The Lounge", please let me know.
This is the story of my longest running Macintosh (nicknamed Pulse), which is still running 24/7 after 17 years.
A while ago, circa 2002-2003, an apple reseller gave me a dead G3/233...
Noticed a few month ago that the 53C80 SCSI Chip is in life production by Zilog, available new :
Mouser link : https://www.mouser.fr/ProductDetail/692-Z53C8003VSG/
COVID helping, I bough a broken MacSnap SCSI on eBay and started to reverse it. I though it will be cool to gave a...
Just picked a couple of Radius Pivots for a few bucks. Model 0194. From my memory, they need a specific video card. Found one on eBay, waiting for it.
First issue : no cable in sight for both screens. Anyone got the pinout ? Would a straight DB9 cable work ?
Second issue : none of...
This is a quick guide on how I upgraded the PSU on my Performa 6200. This guide applies to all macs which share the same case (Quadra/LC/Performa 630, Performa/PowerMac 62XX/63XX)
PowerSupplys inside this case are an afterthought. They are badly designed and the first...
The PPC card on my Quadra 650 isn't detected anymore, neither by the PPC601 Control Panel or TattleTech.
I tried in a Quadra 800 and no luck either.
The regulator get hot (40-50°C by hand), and the CPU get a little colder, so there is power going through it.
The thermal paste is bad...
Was busy cleaning some NuBus cards and noticed something weird on this card. I'm amazed it's there, as usually you will find something more a 68HC05 or 68HC11 performance wise, so it has to do some "heavy" processing.
Pictures attached for reference
What it is for ? Something...
Hello everyone :)
Long story short, I got a 8100 a while back, which had some sort of PSU fault which resulted in a dead motherboard (burned area of 4 cm^2 + tons of smoke :O ). Salvaged some parts of it, included one HPV card (820-0509-A). I want to use this card into my...
