Welcome to GarberStreet Electronics
Dual ROM board for Apple II+
 

I have 2 prototype style boards left. 
If you want one, email me and I'll 
be happy to build and send you one.

NOTE: Due to the lack of interest, this board will
no longer be produced, unless more interest should
arise in the future. 

Simply remove all 6 ROM chips from your motherboard,
and the 74LS138 next to D000, and install this board
into the D000 and 74LS138 sockets, and put your
74LS138 into the ROM board and you're good to go.

Add a Single Pole Single Throw switch to the header,
and now you've got 2 ROMs that you can go between
and no slot is used. Applesoft is the default, and
Integer is switched in with the switch. Or, if you
wish, we can program the ROM with one of those
and one that you've modified.
