Any idea what that blue Data General machine was? Some kind of terminal
server?

Hi folks,
I think the NI Ethernet device is ready for some real world beta
testing. I have put up a page here with details about how to build SIMH
and how to install the "NI" ethernet drivers and TCP/IP software here:

P3 has no protection P5 does
a P3 can be read with a Data I/O Unisite

The P5 is more involved. You put it into factory test mode, feed it a NOP

and it will output the rom data
One final note:
I didn't get pictures of these, but Kemners has probably 20-25 IBM external
5 1/4" floppy drives, about half of them are 360K and half are 1.2MB. Two
of the 360K drives are NIB, wrapped in their original plastic.

As I understand it, this MCU requires executing a particular program from
external memory to access the internal EPROM, both for programming and

I will write a utility to dump the contents if necessary, but I am

Note that SIMH always writes disc images in little-endian format,
