I told Den that he shouldn't hold up distribution of the TAPR boards until they complete their software, a project that might take a while. I felt that other people might want to write their own software for the units. Here is Den's reply:

HANK,

I AGREE WITH YOU ABOUT THE OTHER WORK THAT COULD BE DONE. I WI LL GET THE BETA BOARDS OUT AS SOON AS THE ALPHA BOARDS ARE SHOWN TO EXHIBIT NO FATAL FLAWS. GIVE US ABOUT A WEEK TO TEST THE HARDWARE WITH SOME PRIMATIVE ROUTINES, THEN SOME TIME FOR A LAYOUT-MODIFICATION CYCLE. I COULD TRY TO DELIVER BOARDS SOONER THAN JUNE THAT WAY.

I'LL SEND YOU A LONG FILE ON THE CURRENT HARDWARE CONFIGURATION FOR YOU TO PASS AROUND, AND WILL GIVE YOU A "LAYERED LOOK" AT THE DYNAMIC ADDRESSING PROTOCOL, CONNECTIONS TO IP, ETC. A LITTLE LATER ON. 73, DEN

Re: Zilog Z8530 SCC

There is yet another HDLC chip on the block, and this newest entrant looks like the best chip I've ever seen. It seems particularly well suited for amateur radio applications, and I wanted to bring it to the attention of all people thinking about designing TNC's or controllers.

First, some info straight from the spec sheet:

ZILOG Z8530 SCC SERIAL COMMUNICATIONS CONTROLLER
