jjonas Posted January 14, 2013 Report Share Posted January 14, 2013 Hi, I thought I'd drop a few lines on an MBSID build into a C64 datasette using one nanosid (i.e. swinSID). I had leftover parts from my "main" MBSID build; I had originally planned to build four cores, but I couldn't fit them all into the C64 case that I used. So I had all the parts lying around except for an LCD, which I now decided to get, and put the parts to good use. I had two SID module boards from Mike, but in order to save space I decided to etch my own "double SID PCB" (and a DIN2 board as well) using the laser printer + clothes iron method. This was my first etching project and maybe the quality could have been better, as I couldn't get the other half of the double board working. So in the end I just made it with one sound chip, I hope I have time and energy in the future to redraw a complete core + 2 sids PCB with Fritzing or something for an optimal fit.. and anyway it's good that all projects are not finished immediately :-) At the moment the datasette insides are a mess, as I guess with most of these modular builds. But it works. I decided to use nanosid instead of the real thing because that made voltage supply much easier – you just need one regulated 5VDC for both the core and nanosid. Plus it's less noisy than a 6581. I kept all of the the datasette's buttons to have them push the actual MB buttons 1-5 + menu. The core PCB regulator (follow the red-white-black wires) is attached to the button plate for heat sink purposes. The two buttons on the right that are hanging loose (Up & Down) will to into the counter hole once I get my hands on a hot glue gun... the LCD is attached to two screws that I hot-glued onto the datasette cover.

Johey Posted January 15, 2013 Report Share Posted January 15, 2013 This is about the coolest MBSID I've seen! Great job! I have a couple of datasettes too. This is inspiring... :) Quote Link to comment Share on other sites More sharing options...
Imp Posted January 15, 2013 Report Share Posted January 15, 2013 Nice Build! I like what you did with those buttons! At the moment the datasette insides are a mess, as I guess with most of these modular builds. I can confirm this (at least for my SID), but who cares as long as it's nice and works, when the box is closed? Quote Link to comment Share on other sites More sharing options...
jjonas Posted January 21, 2013 Author Report Share Posted January 21, 2013 Here's a video I made, I'm using a MIDIO128 to control the MBSID to play a simple tune. I have also ditched the old double SID module I had as there was some problem with the second half, and used Fritzing to redesign a new double SID module to save space; I ditched the rectifier and regulator bundle, as SwinSID can be run off the core's 5VDC regulator. Also the audio in had to go. Quote Link to comment Share on other sites More sharing options...
