Well I have started construction on my MB SID which I am going to name sidated (hopefully no one has named theirs that yet)… I am building the stereo version with the 6581 chip… Last night I finished constructing the core/DIN/and 2 sid modules that I purchased from Smash TV… All I can say is that the quality of the PCB’s are excellent and the way everything is packed is awesome… Today I will do the tests on the boards whith the IC’s removed…
Next task will be mounting a 2x24 LCD, encoder, and the 11 buttons on some perf board and source some ribbon cabling and connectors… I will post pics here to document the construction process… Should have some pics up by tomorrow…
Whoa Cosmosuave, great photos! I see what might be a problem, hoping I am just seeing things…
I’m looking at the 2200µ (larger capacitor) in this photo:
It looks like it’s backwards (negative/positive swapped) and swelling up.
Please check the polarity before you power it up again, capacitors get messy and very loud (think .22 shell fired at close proximity/no earplugs) when they let loose and go ballistic.
I should have some spares in the floor sweepings bucket, ping me if you need one!
I am curious to know why it looks like there are 10 select buttons but only a 2x24 LCD… for a 2x24 LCD, there should be only 6 select buttons (6 x 4 characters = 24). ???

Looking at the size and shape of the LCD and buttons in the first pic, I’d assume he’s swapped the 2x24 for a 2x40..
Hey Smash you were correct about the cap being backwards… I have since replaced it when it blew… Gotta learn the hardway… After several failed attempts with 2x20 lcd I was successful with a 2x40 only issue is that it is non-illuminated… I am eager to get this done after hearing some recent sound bites… I need to make a trip to the electronics store soon to finish the power supply and grab some ribbon cable for all the connections…
Thanks for the pic compliments… A curved piece of white paper does wonders…

Hahahah! Yeh I used to do hardware repairs in a small, rectangular, all-concrete basement… When a PSU cap went off it would reverberate around the room and it was like a horde of angry pixies bashing you in the ears with baseball bats ;D
