The Sega Development System [Version 2.0] [Accolade] [1991-02-21]

This one is a bit more interesting as it was made prior to the Sega vs Accolade court case about the whole reverse engineering thing for boot code.
Also has some handwritten notes in pencil (didn't scan very well...) that can be seen on some pages.
Oh how I love trial and error, seems to be the way they worked some of this out too.
Enjoy the read! Anyone who see anything cool amongst these pages, please leave a comment!

Haven't looked yet, but the notes sound good! It's possible that greyscale got rid of them, but it should be OK. Anything of particular note that doesn't show up in the scan that's in the original?

Thanks!

 

Not that I could see, if you feel the need for me to redo any, just let me know and I'll give them a good rescan.
Greyscale seemed to be the sweet spot for scanning, black-only-mode completely obliterated anything not text and colour made the file sizes blow out massively.
Pencil is greyscale anyway, it should be good - have a peek! I haven't really read through it myself yet either though!

 

You had some of the PCBs on their own as well didn't you? I was gobsmacked when I saw that!

 

This one is indeed very interesting since it is basically coming from reverse-engineering notes from Accolade engineers so it includes undocumented bits compared to the official documentation that we already know.

Thanks a lot for all these scans by the way, this is very informative work !

 

No worries and yes I find it fascinating how Accolade did what they did.
If you spot anything way past cool in there do give us a heads up! :smile-new:

 

Thank you for sharing!

 

I bring you peace and love! :topsy_turvy: and manuals! :biggrin-new:
