Taкже сверху на D38 необходимо напаять D38' (1533ИР23) всеми выходамиconnected to D38, and the inputs are connected to the corresponding outputs of D37. Signals C3 and 2-D3 are supplied to the 1st pins D38 and D38', and to the 11th pins signals C29 and C3, respectively. Also on pins 9,12,15,16,19 of the microcircuit D40 needs to be grounded through 1k resistors. ┌─────────────────── ───────────────────┐ │ 512x192 & Multicolor for Scorpion │ └─────────────────── ───────────────────┘ The circuit is the same for both options, slight differences for the 'Yellow' board shown in brackets. PS: I haven’t personally tested the multicolor scheme (I don’t have Scorpio at hand yet), so write about the glitches you find before I leave to trample my boots... ┌──┬───┬──┐ ┌──┬───┬──┐ GND >──2┤A0│MUX│ │ 5-D2 >──2┤A0│MUX│ │ 11-D13 >──5┤A1│ │ │ 6-D2 >──5┤A1│ │ │ 6-D3 >─11┤A2│ │Y0├4───────────────────11┤A2│ │Y0├4──> 9-D40 12-D33 >─14┤A3│ │Y1├7──> 3-D18 6-D3 >─14┤A3│ │Y1├7──> 7-D39 ├──┤ │Y2├9──> 1-D19 ├──┤ │Y2├9──> 6-D17 6-D3 >──3┤B0│ │Y3├12─> 11-D43 6-D1 >──3┤B0│ │Y3├12─> 9-D1 (11-D1) 6-D5 >──6┤B1│ │ │ (11-D42) 5-D1 >──6┤B1│ │ │ GND >─10┤B2│ │ │ 6-D3 >─10┤B2│ │ │ 13-D33 >─13┤B3│ │ │ GND >─13┤B3│ │ │ D1,D2 - 1533КП11├──┤ │ │ ├──┤ │ │ ┌─────1┤AB│ │ │ ┌─────1┤AB│ │ │ │ ┌─15oOE│D1 │ │ │ ┌─15oOE│D2 │ │ D6 - 1533ЛE1 │ ─┴─ └──┴───┴──┘ │ ─┴─ └──┴───┴──┘ │ ■─────────────────■ 7:TM8 (see diagram above └───────────────────────── ─────────────────────────■ 2:TM8 for Pentagon128) D6.1 │ D6.2 3:TM8 ■───┤<├───■ 2-D11 ┌──┐ │ ┌──┐ KD522 6-D13 >──2┤1 │ └──5┤1 o4────■─> 10-D33 ┌──3┤ o1───────6┤ │ └─> 10-D34 ─┴─ └──┘ └──┘ D6.4 D6.3 D4.2 ┌──┐ ┌──┐ ┌──┐ (8-D14) 12-D31 >─11┤1 o13────8┤1 o10────> D39:15 5-D35 >──5┤1 o4─■─> 3-D33 1-D15 >─12┤ │ ┌──9┤ │ ┌─6┤ │ ■─> 4-D33 └──┘ ─┴─ └──┘ ─┴─ └──┘ └─> 3-D34 Disconnect only these pins of the microcircuits: 6-D3 -IE7 3-D18 -KP11 6-D17 -KP11 1-D19 -KP11 3,4,10,11-D33 -KP13 3,10,11-D34 -KP13 7.15-D39 -ИР10 9-D40 -ИР16 11-D43 (11-D42) -KP13512x192 is enabled by setting bit 1 of port #EFF7 and disabled by RESET or by resetting the same bit.
