I already have a Snap Circuit 300 or 750 kit from Elenco!
If you have the Snap Circuit 300 (SC-300), all you need to do is go to the Parts Order Website below and order a few extra parts. Be sure to request the book for Snap Circuit 202 or download and print it yourself (instructions below). If you have the SC-750 all you need is the last item in the list (3-spring socket) and the manual to be compatible.
To convert "Snap Circuit 300" to "Snap Kit 202" you need to order these
replacement parts from Elenco:
one -- 6SCM3
Electromagnet $6.95
one -- 6SCM3B
Iron Core Rod $0.75
one -- 6SCPY1 2-spring socket $2.95
one -- 6SCPYQ 3-spring socket $3.95
One -- 753296 Manual for the Snap-Kit 202 ($9.95 as of December 2009)
You must request that the RS-202 manual be included in your order. You cannot order the manual from their website. Give the company
special instructions to include the manual for the Snap-Kit 202 when you place your order for the above parts. The part number for the manual is 753296, ($9.95 as of December 2009) and you must request this item because there is not a link on the website for this item.
