Thanks to the analogue-sequencer Yahoo! Group, a discussion group for individuals interested in the Sequentix P3, I ended up getting in touch with a guy by the name of Mark Pulver who was in need of having his Sequentix P3 kit assembled. I sent him a link to my Sequentix P3 page at nuxx.net and photos of my P3 assembly and I imagine he liked what he saw because he asked me to assemble his.
After languishing in transit for a week and a half between his place and mine, I stopped off on the way to work and picked up the package from the post office. It was a quite large, well-packed box which should be just about right for safely shipping it back to him once it’s assembled.
Before getting to work I had to dig around for a while and locate the old Sequentix P3 assembly instructions. See, Mark actually has a kit for one of the original P3s, serial number 008, before the restyled and rackmountable case. These older versions also had a different PCB layout and BOM, so I couldn’t use the normal DIY instructions. I find this quite interesting because I’ll now have built both versions of the P3. I’m not sure how many people besides Colin Fraser, the creator of the P3 have actually gotten to see both of them in such detail.
Tonight I managed to assemble most of the easier parts of the PCBs. As can be seen above (or here full size) I fitted the sockets, resistors, caps, diodes, sockets, and other small parts. Tomorrow I hope to get to the pots, switches, LEDs, and other parts which are considerably more particular about placement. Since they are what the user actually interacts with I want to be particularly careful about them. After that it should just be a matter of completing the major component assembly, testing everything, ensuring that the firmware upgrades work as expected, getting the MemX memory expansion working, testing it all thoroughly, then sending it back. Hopefully by the end of the weekend that’s where it’ll be.
After this I may be doing some similar assembly work for another P3 (newer case style), an ASM2, and possibly some Blacet modules.
