TOS104 / TOS102 MEGA ST

Adapter pcb to plug into most MEGA ST machines which gives a jumper selectable TOS 102 & Rainbow TOS 104. This kit can be used as a stand alone TOS upgrade and also can be used in conjunction with the V1.5 16mhz booster to give fast ROM access.

Going by myself and the one other person I recently suggested this kit to, it's very common to lack the 74LS11. It's a very cheap chip, unless you need to find a local supplier and pay postage for a single one ;) Maybe you could supply them with the kit?

I could do in future batches of the kit if I can source the chip cheaply enough yes.
