PAK68 Accelerator Schematics for all! :)

Kai · 21 April 2011, 11:30

Hey everyone - i thought as a first post - what better way to introduce myself, than to post up the full article on the original PAK-68 accelerator from C't Magazine (August 1987). I managed to contact the editor of Heise Online, and he mailed me out a mint condition back copy for free!

So, i scanned it in as hi-res, and voila - here you are!

There are no GAL/PAL's involved, just 74LS Glue Logic, and discrete components. This would also work with an SMT 68EC020 as well, i reckon.

Yes, it's in german - but all we need, are the schematics

Good job, thankyou very much.

A moderator will welcome you to EAB, they will be along shortly

TCD · 21 April 2011, 14:23

Hmm? Oh...

Hi Kai and welcome to EAB!
Great first post and enjoy your stay

Kai · 21 April 2011, 14:43

Thanks people

I have the articles for the PAK68/2 and the PAK68/3 as well, with the schematics and PAL/GAL equations too, if you want me to put those up later?

TCD · 21 April 2011, 15:11

Sure thing

I've made a PDF of the article and uploaded it to the EAB file server in the folder 'Doc/App_Hardware'. Hope that's okay for you?

musashi5150 · 21 April 2011, 18:09

I have one of these sat in front of me on my desk at work. It doesn't work, maybe these will help

Pak68/3: http://kai.robinson.free.fr/dropbox/...11.222-231.zip

The schematics in that Pak68/3 are awful, unfortunately, if anyone has any better quality ones, they would be appreciated.

C't still sell the back issues - although i got the August '87 copy free of charge - literally, i asked if they had one, and two days later, a very efficient german man had sent me a mint condition copy!

Pak68 (original): August 1987
Pak68 (FastPAK): January 1990
Pak68 Kickstart Patch: April 1990

Hmm...tried to look in 'The Zone!' and turns out i don't have access...are there minimum requirements, or does my account need to be poked at by an admin?

TCD · 23 April 2011, 14:49

1.) Click on 'Rules & Help' at the top of this page.
2.) Read the board rules carefuly.
3.) Click on that funny red link right below 'vBulletin FAQ'

Kai · 27 April 2011, 15:40

Just got an email from Thomas Hoffmann @ Heise Publishing, regardling all the PAK related articles. I gave him the dates for the articles, and he's going to scan and PDF them in personally - so we may end up with better schematics after all!

Zetr0 · 27 April 2011, 16:57

@Kai

Thats fantastic news to read indeed!

Kai · 27 April 2011, 20:35

Did the stuff i uploaded the other day help yours get finished?

Zetr0 · 28 April 2011, 02:49

@Kai

alas I have not had the time, with bout a billion project blasting off the walls alas I had to let the PAK68/3 go to a friend whom could best use it in their Atari ST....

However, the sources are a great read and will provide a great basis to build a similar adapter for an A500/CDTV in the future.

I cannot thank you enough for sharing them

now.... have you told TCD the best bit yet?..... y'know... the fact he has to translate all the PDF's to English =D

Tell you what Zetty : Once I play the first demo of that Captive remake, I'll start translating =D

you do know.... now that you have said that.... I will hold you to it

TCD · 28 April 2011, 21:22

Bring it

Kai · 29 April 2011, 04:01

Might be easier to build the LUCAS to start with instead of a PAK/3 - fewer PAL/GAL's and the PCB masks are already in the PDF file i uploaded

Would be nice to have that converted into a gerber file, too!

Now all i need, is an A500+ so i can have a go at making it myself
