1. PCB Making[DEPRACATED]

I have no time to finish self-maid boards so ordered full set of pcb's: 10 pcb - base boards 10 plates with 24 different modules on each - 240 modules 2AND/2XOR 2AND/2OR D-trigger 2&(3C+1A) Diode(8)

Equipment

6. Progress updates:

Update 12/1/2019:

  • BFPC Frame is done, and all computer parts are placed on chassis;
  • Memory board is working enough for BFPC start;
  • Logic blocks are 30% done

Update 24/05/2018:

  • D-triggers for TMP/CMD register block done;
  • All block housings are printed;
  • Indicator boards assembly finished;
  • Soldered all latch modules;

Update 26/02/2018:

  • Adder Block done and tested;
  • IP/AP register block done and tested;
  • Continue soldering D-trigger modules;
  • Created indicator modules. Soldered two of them. Fw for one is done;
  • Created latch modules. Soldered two of them;
  • Start working with memory board firmware.

Update 14/12/2017:

  • Soldering D-trigger modules. Need 64+, got half of them
  • Designed indicator board
  • Start wire-wrap of adder block

Update 12/11/2017:

  • Ordered pcbs from easyeda and got it.
  • Soldered all 2AND/2XOR modules for carry-chain adder. Start soldering base plate for it.
  • Done with modules tester - didn't check any relay but will check all modules.

Update 05/06/2017:

  • Only in third attempt I painted some boards with solder mask. It's a diode module, 2ANDx4 module and 2& module - two plates of each type. Currently can start drill and mill them and start assemble the modules.

Update 17/04/2017:

  • Rework and optimized ADDer logic. previous version needed 64 modules with 3 different types: ADD+C, 5AND, 2AND/2OR. New version need 32 modules with 2AND/2XOR type; One basic block would be used for latches.
  • Done with memory Board module routing - Already got ready pcb from manufacturer and currently soldering it.
  • Done with prepearing for solder mask operations - will start with this one as soon possible;
  • Thinking about memory module firmware. Start developing it's arch.

Update 08/03/2017:

  • I'm done with all known modules etching 30 pcbs! All adder modules, all register modules are ecthed;
  • Created and etched some modules for logic block - I have 64 modules capacity on it and have only preliminarty schematic for microcode;
  • Next step - apply solder mask on them and send to drilling and milling. After this steps I will start soldering modules.

Update 04/03/2017:

  • Put image on another 6 plates and want to etch them in near future - 3x5AND, 1x2AND/2OR, 2xD-trigger.
  • Almost finished with Memory Board routing. Need to fix power lines and check all connections.
  • Prepare plywood table for photomask - it's ready for use and I want to start when finished with all known boards.

Update 25/02/2017:

  • Etched additional 12 pcb's - 6 pcb of D-trigger, 2 ADD+C, 1 5AND, 3 base boards.

Update 23/02/2017:

  • Suddenly found that I have D-trigger unrouted yet. Fix this issue and got one-side pcb with one jumper. Printed Photomasks and Imaged two plates;
  • Modified ADD+C routing into one-side pcb with one jumper. Reprinted photomasks and made one of two Images;
  • Bought thermal laminator for doing photoresist operations better - when I start etching I found that they are a lot of issues with images quality. First test gaves me stable good image quality after I just found proper temperature;
  • Currently I have 5 etched plates and 7 - waiting for etch (will do it in 2-3 days).
You can’t perform that action at this time.
