I have been laying out the TCU RAM array.  Jim has been finishing up the
CCU arrays.  We are almost done.  

The Math board schematic is done and it is being layed out.  I am still
working on some errors in the connect lister.

We are not going to use the Bobcat battery and holder.  I does not have a long
enough life.  There are no large concerns with using the silver oxide battery.

I tested the battery isolation circuit and the the write protection circuits.
I made some changes to give them more margin.

I received the Toshiba 2K x 8 screened 25 ns SRAM's (60 parts).  I have not
looked at them yet.

The Stantel rep called and said that they will have production 2K x 8 25 ns
SRAM's in march and samples in February.

I will receive some SOJ packages from Toshiba in about a week.  We can get
1 Mbit nibble mode parts in the SOJ package in March.  I am going to order
some parts for one board soon.

Some concern has come up regarding board test of the SRAM's.  I do not think
that there is a problem.  I still need to follow up a little more on this.
