ok, let's maybe take out the requests off the list? I'll make a list
and see how many modules would be and then calculate a price.

If you did not want to use the Libero method you could use a 74HC148 (or
similar) 8 to 3 line priority decoder and put the 4 CSx- lines into the upper
or lower 4 inputs of the ‘148. That would recreate 2 a
ing on the
M100 required.

thanks! It seems like we should be able to use the 8x8 chip from the 102 with

All,
Those $3 chips work fine in the Model 102, but I believe the pinout for
M100 RAM expansion is slightly different and doesn't plug in directly.
I would have to double check, but I recall the SRAM chips were always on
a carrier PCB to remap the pinout.

Wow, a quick check reveals a 8kX8 SRAM on ebay for $3. Didn't those

The chips are available they are standard 8Kx8 SRAM. Should be able to find
some on line.
Unfortunately the QUAD is only for the Model 100, it will not fit the 102.
Congratulations on your new addition :)
