Here's some more technical info on the various boxes.

I've always loved collecting brochures on some of the more esoteric products available for Macintosh computers back in the day. In the early 90's I saw an ad about adding 8 slots to a Compact Macintosh and I wanted to find out more immediately and sent away for the brochure. The company was...

Hi - I've a Macintosh LC and a Performa 475 which I know share some common components. There was no sign of life when I switched the LC on so I thought it might be an issue with the power supply. The Performa 475 is working fine so I opened both up and moved the good power supply from the 475...

I remember being shocked at the size of the Orion board when it arrived from MacLine and wondered how on earth I was going to fit both it and the original logic board back into the SE with memory fitted to both boards adding even more height! This was decades before any forums or youtube videos...

From memory it looks almost identical to the one shown in this thread with the velcro over one of the chips: https://68kmla.org/bb/index.php?threads/identify-this-board.1052/ I always thought the velcro fabric was just to prevent the board from touching some piece of metal inside the chasis as...

Back in late 80's MacPeak Systems were naming their accelerators and video adapters using some sort of futuristic 'star' theme with names like Orion and Galaxy. Did anyone ever own the Galaxy video board that plugs into the Orion accelerator in the SE and supported both single page and two page...

Great stuff - thanks! I read your notes and laughed especially the bit about the handmade cable! It's that cable that I think is causing my issue which is I occasionally get a green tinted display instead of beautiful 24 bit colour. I've confirmed it's not the monitor or the external cable as...

Thanks for the info which was really useful. I'd previously checked an Apple Service video for the Select 310 printer which was interesting to watch but it never mentioned anything about wipers needing replaced: Still it showed how to strip the machine if I want to clean the panels etc or...

Hi - I've an old Apple Laserwriter Select 310 from 1993 but new toner cartridges have not been manufactured for a long time. The printer was only ever used by me so has had very light usage over the years. I've confirmed it still works in terms of going through the motions of guiding the paper...

Did you ever figure out what the board side pinout is for the internal cable? I too have the same RasterOps 264 colorboard in my SE/30 and would like to make a modification. As far as I am aware this is the pinout for Mac DB-15 and VGA connectors: Signal Mac VGA Red video 2 1 Red ground 1...
