Dual EtherStreamer MC 32 "Dual Dunes"?, FRU P/N 73G7141, P/N 73G7122(A) [P] [P]

Two EtherStreamers on the same PCB. Similar to the Dual LANStreamer.

P1 MCA card edge
P2 RJ-45 Eth. "Port B"?
P3 RJ-45 Eth. "Port A"?
T4,14 Valor SF1012
U17,106 73G7133 microcode flash

Y1 40.0000 MHz osc (MCA BM & Eth.)

U26,51 73G2692 MPC (Multi-Protocol Chip) contains a Token Ring and Ethernet MAC.

U30,60 63G9811 MCA bus master interface chip "Maunakea".

U13,50 (back) Cypress 31F2259 CS4226 or Toshiba T2259 (MCM6265CJ15 compatible?) 8Kx9 SRAM


Dual EtherStreamer MC 32 Early "Dual Dunes"?, FRU P/N 73G7141, P/N 73G7122(A) [P] [P]

Same as the newer revision above except the PCB doesn't have a provision for the 74F08 Quad-AND (U57). Instead the IC (EC) is glued to the board upside down ("dead bug"). It's wired to the DPADP10 frontend chips and 73G2692 Multi-Protocol chips.
