...
BOM note:
the most important things are:
| PIC chip | preprogrammed with bootlader | ask me if you want one preprogrammed PIC chip | |
| SID chips | 2x needed - one minimum 8580 or 6581 or 6582 | ebay or ask me | |
| Frontpanel and rearpanel | see note for the ID:output in this list to improve the rear panel | http://thebeast.co.uk/?product_cat=midibox schaeffer | |
| original power supply (latest square box version) | ebay | ||
| powerswitch from ebay- or use a DPDT switch on rearpanel | |||
| Powersupply DIN Jack | |||
| low current LED´s - which fit against the front panel hole | make sure the color match with the display | tme, mouser | |
| Display HD44780 | make sure the color match with the LEDs | ebay or | |
| case Pactec PT10 | mouser | ||
| FAN only when you install 6 or 8 SIDs | 5Volt 40mm fan - ebay | ||
| 9x flat ribbon cable to connect the pcbs together | FST-21A-8 | ||
DO NOT INSTALL ALL headers and IC sockets or output drivers if you only want 2 SID chips - you have to install and buy less parts | you only need 2 SID chips and one preprogramed PIC chip. more SIDs. can be played on a different MIDI channel - but there's no real Polyphonic playing on one midi channel. (correct me if I´m wrong) | everything inside the blue marking isn't needed when you only want a 2 SID chip version. also the headers which are blue marked.
| |
| ID:output | ABSOLUTLY important | the outputs are Stereo per jack !! if you only install 2 SIDs - you can improve the jacks - install 2 MONO Jacks at the rear panel and connect each on the (Voice 1) stereo solder holes - other wise you need a adapter from stereo to 2x mono cables (insert cable) | todo: improve the rear panel to 2 or 4 MONO jacks (9.5mm holes) move the holes more to top to get enough space between PCb and the jacks. remove the unused holes from the panel files |
Build Infos (mostly for myself)
