Page 6 — Overview Drawing: External Connection Leads (BBE 910.000.00.0, Sheet 1)

A schematic overview drawing titled “Übersichtszeichnung Externe Verbindungsleitungen” (External Connection Leads Overview Drawing). Dated 21 May 1973. Published by DORNIER electronic.

The drawing shows the wiring of external signal connections between sub-units. A central connector (St 43, labeled “Lüfter” / fan) fans out to four sets of leads labeled A, B, C, D. Each set connects the rückw. Einschub (backplane slide-in) to the Gehäuse (housing) through connector pairs (A1/A2, B1/B2, C1/C2, D1/D2). Signal designations include cable IDs: SS 20/1, /B3, /D3, /F1, /H1, /L1, /EE, /HW and connector positions AT1, AT2, BT1, BT2, CT1, CT2, DT1, DT2 at the housing level, plus RS 20/2, S 23/2, S 24/2, S 28/2 at the lower connection points. Rückw. Einschub connection points and Bd-Einschub (board slide-in) are shown at top and bottom.


Page 7 — Overview Drawing: Manual Switches with Relays (BBE 910.000.00.0, Sheet 2)

A schematic overview drawing titled “Übersichtszeichnung Handschalter mit Relais” (Manual Switches with Relays). Dated 21 May 1973. Published by DORNIER electronic.

The drawing shows the functional chain for four control channels (A, B, C, D):

Each channel consists of: Taste/Lampe (pushbutton/lamp) → Entprellungs/Flip-Flop/Lampentreiber (debounce/flip-flop/lamp driver) → Trennverstärker (isolation amplifier, labeled △) → Relaisverstärker (relay amplifier, labeled △) → relay contact(s) connecting to external points.

The channels connect at the top to a Frontplatte (front panel) section labeled “Bedienerschnitt” (operator interface) and at the right to a Potentiometereinschu. (potentiometer slide-in module).

Signal designations include S5-105, SE4 B, SE4 B, SE17 C, SE24 A and similar numbered lines. Operating voltage references: S5 0A, S23 4, S24 7/C, SE22 4, SE20 A, SE58 4.


Page 8 — Overview Drawing: T/10 (BBE 910.000.00.0, Sheet 3)

A schematic overview drawing titled “Übersichtszeichnung T/10” (T/10 Overview). Dated 21 May 1973. Published by DORNIER electronic.

The T/10 circuit controls a timing/switching function for the computer. The diagram shows:

  • Two remote connectors (Fernbed.-) St41 and St42 at the top.
  • A relay (Thr.-Relais) whose contacts feed through to the housing (Gehäuse) and to a backplane connection (Rückw. Einschub).
  • A divider (Teiler) and a pulse generator (Zeitgeber) block.
  • An Entprellung/NOR-NOR/Master block (debounce / NOR-NOR logic / master).
  • A T/10 counter/timer block.
  • A lamp/pushbutton (Taste/Lampe/Tipp-Schalter) with output S2 at the bottom left, connecting to the Frontplatte (front panel) and Bedienerschnitt. (operator interface).

The circuit divides a timing reference by 10 and provides manual override switching.
