The National Semiconductor 32000 series CPU was the third entry into
the serious microprocessor market.<br>
<br>
1. Intel 8086 (16-bit)<br>
2. Mororola 68000 (32-bit internal, 16-bit external bus)<br>
3. NS 32000 (32-bit internal, 16-bit external bus)<br>
<br>
There were 5 chips in the original chip set:<br>
<br>
NS32016 CPU -- considered the "best micro-CPU on which to run
Unix"; later, the NS32032, a 32-bit bus version.<br>
NS32081 FPU<br>
NS32082 MMU<br>
NS32201 TCU -- timing control<br>
NS32202 ICU -- interrupt control & timers<br>
<br>
Marketing-wise, the 32000 was a disaster for National. It came out
too late; most manufacturers had already chosen to go with Intel or
Motorola.<br>
<br>
I just uploaded the chip data sheet to the ECB Multifunction
Controller folder on the Wiki.<br>

P.S. I think all of the chip data sheets are on <a

Hi Folks!</p>
<p class="MsoNormal">Where is the information of
the N32202 PCBs? I noticed in the inventory

it and they are free? Are they a pre-N8
