Finally a new start to a MB6582 :)

The first steps to a new MB6582 :D all 1kohms placed

Good way to start 2016

What tool are you using to hold the pcb? looks interesting. 

[dreamer]

I bought a ideal-tek PCSA-2. Very awesome tool. You can completly stuff youre board if you want then close the lid and turn it around to solder everything.

So i'm almost that far that i can put first power on my new MB6582 Base board. I wondering about a measurement before i continue. 

In this example i'm measuring on J4 "pin GND" and "pin 5V" I did 2 measurments:

               1st - Continuity test (With beep on multimeter) ==> NO BEEP WAS HEARD, so no continuity.

               2nd - Ohm measurement ==> Measuring about 2.330 kOhm as seen in the picture.

Now my question is this a short or is this normal?

Hola,

I would not worry, there is no short, the measured resistance is caused by some components already in place.

(Is that a switching regulator right to your probes? Which "MB6582 Baseboard Power Option" type are you building?)

Recommendation: measure again without ICs installed, when the PSU is attached and you turned on the unit. Then, there should be around +5V across the PIC power pins... 

Many greets,

Peter

First time power up alway exciting moment :D

 

So it works  but i have a issue when using 6581 12V sids. Will post this in the troubleshooting section.

So the first mb6582 i build back in 2011 i have still laying around and i'm considering te repair / rebuild the base board (will be alot of work to desolder / solder almost everything). But i'm not sure if it's wise to re-use this board. I would love to have a new MB6582 baseboard or set but i don't know if someone still has them. 

And I need a c64 style power switch. Or some other power switch that fits the layout. Are there any other power switches around that fit? Don't want to desolder another original C64.. :(

Whats wrong with the old board?

[dreamer]

Old PSU section on it.. (That reminds me need to have 7 pins din connector also) Lots of low quality components on it resulting in lots of noise. Bad soldering.. Strange behaviour on CS thats probally caused by bad soldering on the base. Also wrong jack outputs on the board that do not fit the layout. 

When i listened to the new board i soldered i allready noticed the big difference in sound quallity.. Thats why i also want to replace the components on the old board. And hopefully also solving the behaviour of the CS board.

I think i have a spare C64 switch for you if you want.

[dreamer]

that would be great :) I hate wrecking working C64 motherboards :D

[Shuriken]

In this case i did that for you

 

[dreamer]

Almost there. The long and painfull waiting for the glue to cure

Looking good, already! :-)

Now, be patient and do not remove these clamps too early :)

Many greets!

Good job! It is always nice to see a newborn MB6582! :-) There are not nearly enough on this planet! :-)

Many greets and have a great weekend!
