Each chip is responsible for 4 bits of data. Enable U61 for expanded decoding.

Since the 68A09 has only an 8 bit data bus it must read the 16 bit Global bus one byte at a time. Now let’s get analog signals into the H The outputs of this chip are sent to U1 04, an octal latch, which deglitches them and maintains synchronous transitions.
The output of the H appears as a processed, but noninverted signal at the output connector J6. The control inputs to the frequency synthesizers are available on the global bus and thus can be controlled by the PELs or by the host processor. When that line goes low, the current MDAC to be updated is selected. Analog Input and Output The audio input is provided by a two channel, bit analog to digital converter sampling at a rate of The Mailboxes are enabled in the same way by U U1 1 5 and U1 1 6 are octal, tri- state transceivers which means they can write to and read from the Global bus which communicate data to the bus.
Some are general purpose bits, intended for handshaking and triggering events. High byte control for above. Consult a data book for more specific operational details.
Each time a read is completed from the delay memorv the address register is incremented, allowing successive locations to be read more efficiently.
They should all be at OdB. The clock signal for U72 is derived from U21 2. Press function then adjust contrast with the knob.
U4 is a hex “D” flip-flop that sends FPD signals to the matrix. Operations such as reading from the A to D, writing to the D to A and writing and reading the delay address are accomplished here.
If, however, a critical component in the A to D fails and is replaced, both channels should be checked and adjusted as needed. U83, Q1 through Q6 are general purpose registers which the software defines and uses.
Is input bargraph lighting? It controls the front panel, loads programs, handles the MIDI interface and many other functions.
This is the first event that needs to take place to get the system up and running. The output of U is sent to the A to D converter section which demultiplexes the two channels then, integrates them to produce a slight DC offset mabual add to the input of the A to D which helps to keep things more stable.
U83 works in the same manner but, it is an 8 bit, addressable latch. The top and bottom should clip at the same time, that is, symmetrically. It provides 6 output signals in the H pins 12, 14, 15, 16, 17 and A magnitude comparator U compares the current 16 bit sample value to a jumper selected offset value and sends a “0” or a “1” to an integrator U1 6A whose filtered output is mixed with the “gross” offset from the diode biasing circuit.
R83 and CR1 4 provide a. This is an interrupt from the PELs to the Brain. The crystal oscillator that drives the converter also serves as the main clock for the entire H The procedure is as follows: Two or more processors can access the bus simultaneously if they are reading from the same device.
