Hi Gary,

Well its been a year.

Some news from here:

Micheal Cranford finished his MAXIPACK and FASTGRAPHICS PACK, and the results are awesome.

50-100% increase in the graphics speed, and he put all the demos and games on the MAXIPACK.

I 3D printed the plastic case for the PACKs and they look good.

I would like to see if we can work together, to clone the ROMs out of the packs you have, or see if you are willing to sell duplicates you have.

I really need a communications PACK, my 4051 did not have the comm port.  I have no way to transfer data in and out, I was going to attempt it over GPIB, bit I did not get very far.

What is new from your end?

I think we are trying to organize a 405x users group, I am talking with a few other guys.
