Here is a collection of small pages where I try and provide answers for some of the questions I've been asked. I also describe some of the things I think I got wrong or found difficult or interesting. This will grow over time.

23rd August 2016

• Web - looking at website traffic

20th May 2016

• Build Faults - new faults found during integration. A proper dry joint. A miniscule short.

29th April 2016

• Build Faults - new faults found during integration, not pushing connectors fully home, some bad solder joints

28th April 2016

• Speed 2 - problems with my clock/latch signals
• Area - where do all the transistors go
• Buses - 16 bits are good, but maybe 8 would have been better

26th April 2016

• History - how I got from studying one transistor as an exercise to building the Megaprocessor
  

11th March 2016

• Build Faults - all the ways I built things wrong
• Flip-Flops - what type I use for my registers
• Modelling - how I structured the software so that I could test the processor as I built it

  Update of DTL/TTL/CMOS .. a friend pointed out that actually I have reinvented NMOS logic, something I'd never heard of previously.

28th October 2015

• Architecture - why I designed my own processor
• DTL/TTL/CMOS - what kind of logic do I use
• 7 segment displays - how I dealt with these
• Board Shape - what I wanted to do, what I should have done, and what I did do
• Gate Dual Output - two for the price of one
• ALU - what's in it
• Memory - I use 11 transistors per bit, chip makers use 4 to 6
• Speed - why it's so slow
• Transistor Efficiency - about half what it should be
• LED power supply -
• My Multiplexor problem - my first big basic electronics problem
• Errors with the Multiplexor - multiple mistakes
• Surface Mount / Through Hole - I chose through hole
• Solder type - I use lead
• Health & Safety - suffering for the cause
