apparently national is making available an upgrade to the designers kit that
is more supportable. this upgrade is free, however since dave raulino
mentioned its availability on the net there has been a run on them and i hear
there are currently backordered.
if people are having specific problems in getting a design based on a 32K to
work i might be able to help solve them. i have put together a number of
32K systems including all of the parts except the MMU. if people post
specific questions to the net i am sure that myself and others would be happy
to try and answer them in the interest of propagating the popularity of the
32K in hopes of more software in the future.

Yes, how did you implement DMA in view of the fact that national cancelled thiers. I mean something that can support 8 chanells for a total throughput of about 40 Mbytes/sec. as the Intel part for the 80386 does. I have ignored the assanine remarks made on this board by the National rep to use the AMD part; I want DMA thats commensurate with the bus bandwidth required by a 30Mhz 32532. I abhor the cavalier attitude that National reflected when they said thier DMA wasn't very popular so they cancelled it. Then they wonder why thier chips aren't popular!
