Note: Chips U1 and U2 are installed on SUN-6334/2. All three chips are installed on SUN-6334/3.

MISCELLANEOUS TECHNICAL NOTES

Model SUN-6334-2 (Ex-4012) only supports two parallel ports, P1 and P2. Consequently, only two socketed chips (U1 and U2) are installed. Jumpers JP3 and JP6 ignored. Model SUN-6334/3 (Ex-4016) supports all three parallel ports. All three socketed chips are installed and all jumpers must be configured.
