New Years Resolution - Build a motorcycle

Good end to the year, as the bike is now in kit form.  Work can now start on cleaning, detailed inspection and reassembly.

A game of two halves

Two halves of the crank case are now separated. A hammer and a block of wood was used around the case until a small gap opened up. WD-40 was sprayed in and left overnight, with a few more hits of the hammer (and undoing the last bolt that was hiding)  the two halves separated.

Sludge!

6502 with RAM

I have now attached RAM to the 6502 circuit. I've created a shot test program that stores a jump location in to RAM then fetches that location to jump to. 

Next step is to plan the pref board layout

Starter motor removed

I have now removed the starter motor, and gear change assembly.  I have one very stubborn bolt to remove from the front engine mount.  The gearbox can then be split!  I have also noticed a small amount of damage to the oil filter cover, so this will need replacing.

Apple One RAM

While building my own 6502 computer I noticed that the CY62256 RAM chips I have, have a completely different pin-out to the HM62256 RAM that is required for my Apple One replica. Doh!  So off to Ebay to order the required IC [Edit] IC found for £2 and on it's way soon.

Clutch removed

Clutch, oil pump and other 'stuff' removed.  Engine left to drain the last of the oil from the engine from the oil pump site.

And the pistons

6502 address decoder

Address decoder built and fitted to the breadboard. Waiting on EEPROM to continue the project

What a tool

Tool to remove the alternator has just arrived, great service - it only took a day to arrive. 

6502 Test rig

After zero luck with the apple one project.  I have started construction of my own 6502 computer.  I have put together a single step circuit and address viewer (both from the apple one manual)

Block Off

Lots of wood distroyed in the process, but with a good soaking in WD-40 the cyclinder block has been removed. 

Off with her head

Not a bad couple of hours work the head has been removed.  The block seems to be stuck firm, I shall leave this for another day!

 Spot the difference, bugger it snapped!
