In a way, the SPARCstation 10 can be seen as the predecessor of the SPARCstation 20
. It also has an MBUS capable of up to 4 CPUs (on two modules), but with 40MHz, it is slower than the 50MHz of the SPARCstation 20. Like the SPARCstation LX
, the SPARCstation 10 has an ISDN interface on board. Sound, however, is not built-in, but only available with an external speaker-box. Other than that, the connections are what you would expect: Serial port, parallel port, 10baseT network and SCSI. Two narrow SCSI harddrives can be mounted and all 10's I've seen so far had a floppy drive (but no space to mount a CD-ROM).
More information can be found in the [SPARCstation 10 Handbook] from Sun. Obsolyte also has an article on the [SparcStation 10].
Several manufacturers produced clones of this machine, like the [Axil 311]? or the [Solair WS19]?.
