v 1.1b has silkscreen updates and jumper for Z version of bubble BARE BOARD for the SBC-85 1Megabit Intel 7110A Magnetic Bubble Memory. The completed board and the 7110AZ module in the photographs are for reference, only the bare board is included.

This listing is for the GOLD version, the TIN version is listed here

NOTE: This board is for the 20-pin 7110A and not the leadless 7110-1 bubble device.

This is a 125mm x 100mm 2-layer bare board. This is the first version of this board so there may be some undiscovered issues and therefore the board is considered a late prototype. Software and additional information on the board is available on the SBC-85.COM project website but the documentation is still coming together.

I also have some BPK70A bubble kits listed here and some 7220-1 bubble controllers listed here

You will need to source an Intel 7110A or 7110AZ bubble chip as well as its five support components, the 7220 bubble controller, and additional (but readily available) components. See the BOM on the project website. Note that on the off-chance that the seed bubble is bad in your 7110A you will need to set up a reseeding circuit. I do not have re-seed or dummy module boards available yet, but should have those finished soon and will include them in my next PCB shop order.
