An 80_1_86? Really. I guess I was never aware that there was one
like
that ever made. I always thought they jumped
from the 8086 to the
80286
CPU.
Do you have any stats on this little baby?
Same as the 8086/8086 except:
slight difference in PUSHF & POPF
has ENTER and LEAVE instructions
Anyone else remember anything else?
Has two *really* fast DMA channels. It was used alot in embedded
applications where you hade to move a lot of data really fast.
Frequently found on SCSI disk controllers (among other things).
The MAD-186 by MAD computers was a PC 'sorta compatible', I used
to have (it was re-badged by TELEX). It used an 80186.
The 3Com 3Server3 was another computer (well, okay, fileserver)
that ran a modified MS-DOS (2.x, IIRC), had embedded SCSI (actually
SASI), ethernet, and serial/parallel interfaces. It also used
the 80186.
