"I recently came accoss the contruction manual for my Maplin 3800 synthesiser and flicking through it I wondered would it be possible to build the 5600s systhesiser today, August 2018, nearly four decades on.
With the passage of so much time there will be a few challenges to overcome namely component obsolescence. Integrated circuits, spring line, patch board, keyboard but to name a few. Please read the 'Hindsight Engineering' section at the end of the page.
On the positive side the build process should be simpler. For me the circuit boards will be easier to produce, no more ferric chloride, bubble etch tanks, spraying copper clad board with photo resist varnish and so on. Just produce the gerber files (I used EasyEDA) and send them off to JLCPCB.
I'm still considering what to do about the patch bay, try to source one or simply bring the inputs/outputs to limited number small jack sockets so they can be 'jumpered' - no room for 900 sockets!
I am also considering usng the Raspberry Pi instead of a keyboard either as a sequencer or as a 'soft' keyboard. I will re-hash my sequencer program for use with the 7" touchscreen and find a space to fit it on the panel."
