As I am often asked just how long a project should take to build, for your information, I timed myself for both preparing the board on Day 1, then the wiring up on Day 2.

	Day 1

	Nothing but a collection of parts and a wiring list at 11:49 Day 1.		First step - fit the rubber feet, the two switches and the power bits.

	A good way to save a little space is to use surface mount decoupling caps. Quite simple for little fingers... (Day 1).		Wiring combs and power to the IC�s shown sorted end of Day 1.

	The time is now nearly 5:00 PM and it has therefore taken just over 5 hours to sort out and mount the hardware, the decoupling caps and the power wiring (including a break or two for refreshment of course!).

	Day 2

It took me about 4 hours to complete the wiring.

If using one of the �eurocard� type of boards, this is how I arranged my sockets to maximise the space useage. Big down point is identifying Pin 1�s. Thus I �blacked� out every pad immediately to the right of each Pin 1 (Day 1).

	Wiring complete, less that needed for the 100Hz source and the 40 way header (Day 2).		Close-up of wiring around the RAM.		A close-up of prototype number 2 with most IC�s in their sockets. Please note that the two DL1414 displays are NOT needed to successfully complete the SITCOM project. They simply give a few more experimentation options IF you have one or two handy in the spares box.

	As mentioned above, whilst those two DL1414 displays are very useful, they are NOT essential, as all the SITCOM�s �programming� states may be identified by the single SOD LED, shown on my version immediately to the right of the blue BOOT button. After switch on, this LED will flash slowly, with other faster flashing rates enabled for detecting downloading program data and error conditions.
