MY SID SYNTH BUILD - with ANALOGBROTHA

MIDIbox SID
1

Hello Every one,

This is my build document,Where Plan to show my progess of my first Midibox build.

Just a basic One chip Desktop module (Core,Sid,) I also bought a din kit (to start with as I will hopfully add on in future, &  good for a little Sodder practice before my core and sid build up)

Controls will include 2 x 20 lcd,6 buttons and a rotary encoder

After reaching this goal I hope to rebuild with keys and realtime cuttoff,rez,a s d r,? osc (analog pots 10k ?)By addjusting MIOS(but I’ll start simple cause I’m far off now)

So Far I have ordered kits,core,sid,din and 2 x 20 lcd and a bankstick (all from smash tv Awsome customer service! thanks

I have gutted a old radioshack mixer (and am replacing top and back with new aluminumn)

Using original commodore buttons (fabricated using some vcr buttons,And cut up commodore)

I will start with all the pics when my orders show.(if ya can still post them,read they were down and hadn’t tried yet)

Please get involved (as I’ll most likely need the help)

Excited to do some hands on learning. :stuck_out_tongue:

Heres the case I built

ANALOGBROTHA

Case in early stage

My Kits arrived from Smash TV (STELLER  packed sooo well antistatic sealed..Boards look amazing! I was so stoked to see them and how much care thought was put into them…Can’t say enough    I’ll be back,as I plan to upgradeThey are now all built up…all parts on..? on the crystal and diaode? if they in the right way?

Case Back

Hope to have more up soon..More of the raw build up

Now I’m Stuck…):

Can I use a 12v 150ma dc psu for sid module? having trouble with power..Getting weird readings?

4

Sounds like your PSU is on the low side. R u using a 6581 or 8580?

5

check your output voltage from the regulator and see if it dipped below 12V, IIRC there is usually a drop across the regulator so 12VDC may not cut it if the regulator is stuffed

6

Thanks for the info and help I’ll check into that!

Broke my br1 for my core :cry:

It was placed wrong (thus the problem with one of my psu’s)

Oh I can’t wait to get this thing running…

7

Could you suggest a psu that would be good..12v 200ma ac/dc?

I’m looking at using 2 power supplys one for core one for sid instide unit

Again thanks!

8

I would just use a 15V one and let the regulators do the work

9

I would just use a 15V one and let the regulators do the work

In that case, where would one connect the 15V? At the Sid or at the Core? Or would this require some funky routing between the two modules?

Having some Problems with my sid module,Can’t get the right voltages (or not sure if I’m checking the right pins?(could not find link?)

Thanks for your help!
