RC2014 Complete..

RC2014 Complete

I got stuck in and finished this today, I did the RAM Module, Clock Module and Base-Board then stuck everything together.

If I thought soldering was nerve racking, pushing ICs into sockets was worse! I don’t know how many pins I bent and unbent before getting them all in – too many!

I can’t test it yet, I have a Pi Serial module, but I’m not going to build that until I can see this working, which will require an FTDI USB to Serial cable, which I don’t have.

I’m pretty pleased with my work, but knowing my luck, I’m not really expecting it to actually work.

Ram & Serial Modules Done!

The first module I did today was the Serial Module. I ran into some problems,

One of the holes for one of the resisters was covered over. I must have spilled some solder or something. I eventually got it though.

Another problem was I broke the connection pins one pin to short, so I’ve had to solder the connection out of two segments… It looks OK.

The third problem one of the IC sockets the pin was bent and hadn’t gone through the hole, and I didn’t notice until after I started soldering… oops. Fixed that one too.

Serial Module

After solving those problems, I decided I’d have a go at another one. So I did the RAM module. That one was fairly easy, no troubles there.

Serial Module

So I still have the ROM module, the clock module and the base board and I also have a Pi Zero serial module as well to do, but they will wait for another day.

Cpu Module... Done!

Last year some time I bought an RC2014 kit to build, I started with the CPU module, but stuffed it up, so I ordered a replacement CPU module but didn’t have the courage to try putting it together.

I decided this week I was going to build it, and today I started with the CPU module. Now, my soldering skills are somewhere between none and basic and my hands wobble when I am concentrating, but I think I did alright!

Z80 CPU Module

I haven’t plugged in the CPU yet, I thought I’d wait until the rest was built before plugging in ICs. I think it looks ok, though there are a couple of spots I’m a bit nervous about. Time will tell if it will actually work when I’m finished with it.
