A1000 68040 project
« on: November 06, 2009, 10:25:10 PM »
Ok - hardware hacking time!

I'm going to connect an A2000 040 board to my A1000.

After seeing http://www.a1k.org/forum/showthread.php?t=6592), and comparing those notes with other Zorro data I've gathered there's just a few things that aren't 100% clear.

The schematic is clear enough with regards to connections, but I need confirmation of the following (babelfish translation isn't 100% clear)...

"Ich hab an diesem Baustein alle Pins, genauer gesagt, den spitzen Teil
abgekniffen, AUSSER den Pins 1,2,3 und 7 + 14.
Am 74LS08 müssen dann die ungenutzten Eingänge 4,5,9,10,12,13 über einen
feinen Draht miteinander, und dann mit Pin 7 verbunden werden.
Den Chip hab ich dann auf den TTL-Baustein, der vorm DENISE liegt, aufgesetzt
und an den Pins 7 + 14 miteinander verlötet. So hat er + 5V und Masse."

What exactly is the above quote stating?

It translates to:

"There's no fraking way you're going to get that 68040 accelerator working from the side slot expansion on the A1000!"


:laughing:

(just messing with you and kidding around)

I can't translate it for you, but have you posted your question on the A1k forums?  They have several people there that could do a much better job explaining in English.

Hope to see your results of your project.  The A1000 is the coolest Amiga case design.
How are you helping the Amiga community? :)

I have at this building block all pins, in other words: the pointed part - except for pins 1,2,3 and 7 + 14 at the 74LS08. Must then solder wires to the unused inputs 4,5,9,10,12,13 from one to the other and then with pin 7 you connect to the chip I have then on that TTL-building block before Denise is installed. Then solder pins 7 + 14 together so you get your +5v.

Not perfect, sentence structure seems a little strange, but... hopefully it helps some? And yeah... good luck with that project! I will not be responsible for any crossed wires!  lol

@save2600

Yeah, that's the translation I get. It is hard to follow exactly what it means with confidence.

@amigadave

Yeah, I'll ask on the A1k forums. The poster might be able to help me.

Goodbye people.

I\'ll pop on from time to time, RL is acting up.

Thanks for the links rkauer...but they are related to a Zorro slot adaptor, not a CPU slot adaptor.

"On this part I've cut off all pins, more specifically the narrow ends, EXCEPT for pins 1, 2, 3, and 7 + 14.
On the 74LS08 all the unused inputs 4, 5, 9, 10, 12, 13 have to be connected with a fine wire and then to pin 7.
This chip I've then piggy-backed to the TTL component in front of Denise and soldered them to each other on pins 7 + 14. This way it's connected to +5V and ground."

(Well, I did my very best - use at your own risk.)
Does sound reasonable though - an easy way to supply power to the part and fix it to the board.
