The constraints are to have a board that is capable of operating with internal masked rom or external EPROM, and that the memory map provide both Harvard separate code and data or Von Neuman combined code and data addressing modes.

There are several pre-programmed memory maps that the user can choose by placing shunts on shorting blocks. One particular memory map will allow the operation of INTEL’s MCS BASIC, a stand alone “tiny basic” system that includes floating point calculations and a rudimentary file system for storing and retreiving basic programs as well as the ability to begin executing a user developed preprogrammed datasheeg program at reset, without any operator intervention. However provision is made for a limited bus to be conveyed to another close-by board.

IC1 typically is stuffed with an 80C32 the rom-less version of the 80C Y1 provides a standard clock frequency of C14, a variable capacitor, is provided for in the board layout but it’s not expected that the component will be provided for the user.

H1 selects the source of the UART 80c2. A shunt across pins 2 and 3 of H2 will cause code to be executed from external memory. It’s understood that these ports already have an internal weak pull-up but the additional current source provided by RS2 is a form of insurance. R14 is included to ensure that the WR- lead is pulled high during the time when the power is on but the reset signal is active.

During the reset period WR- is tri-stated dafasheet its state is unknown. If it goes low it will send a write signal to any enabled RAMs. The pull-up is added to ensure it doesn’t wander low during resets. IC3 provide an address latch to capture and buffer the lower order address signals from the data bus.

SIP resistor RS1 is used to pull up the open drain data bus. Memory Sites TUC52 provides for up to three memory sites.

This is needed when a 27C is installed in this dahasheet. When in this position the EPROM will only be in the code space and not the data space of the memory map.

When in this position the RAM will only be in the data space and not the code space of the memory map. When in this position the RAM will be in both the code and data space of the memory map. When in this position the RAM will be in only the code space and not the data space of the memory map. IC7 provides control of the chip select input to the RAM. H6 selects dstasheet signal for pin 1 of the socket for IC6. A shunt across pins 1 and 2 of H6 will cause IC6 pin 1 to be connected to A This is needed when a RAM chip is installed in this socket.

H7 selects the signal for pin 27 of the socket for IC6. A shunt across pins 2 and 3 of H7 will cause IC7 pin 27 to be connected to A H8 selects the signal for pin 22, the output enable for the chip installed at IC6.

When in this position the chip will be in both the code and data space of the memory map. When in this position the chip will only be in the data space ddatasheet not the code space of the memory map.

H9 selects the signal for pin 20, the chip-select for IC6. It may also be used for a RAM chip datasheeh is not battery backed up. This may be used when a RAM chip is installed in this socket. H10 selects the source for power for the device in 80c322 socket at IC6. Darasheet also that the position of shunts on H9 and H10 must track each other for proper operation.

The converse is also true. Many different memory installations are possible with TUC Most simple applications can run in this mode. In this case IC5 serves as working program memory while IC6 serves as the file system for storing programs and data.

The actual memory mapping is determined by the programming of the PAL. The user selects a particular pre-programmed memory map by placing shunts on H This qualication may be needed for dumb ports like 74hc Shunt D currently has no effect on the PAL.

P1 and P3 of catasheet bits each. For advanced processors like the Dallas DS80C even the P1 port has special features associated with it. The first 82c55 is IC13 which has non-inverting high voltage open collector drivers connected to port A. These drivers can easily be omitted by simply replacing the driver IC with a “straight across” jumper block. Pull-up resistors, formed by RS3, are provided for port B.

These too can be omitted for applications 80c3 don’t need them or don’t want them. Connector Blocks There are three major connector blocks: There is one minor block: All other blocks are expected to be unpopulated.

Additional blocks will usually be unnecessary. Datssheet Control The power control system is the heart of the battery backup system for the RAM devices and the time of day clock if provided. It also includes the system reset circuitry. The goal of the power control circuitry are as follows: The voltage at the input to the regulator is sensed by D3 and Q1.

Note also that during datashdet down conditions that the output of IC16E is low so there’s no current drain caused by IC16E trying to drive an unpowered IC8C’s input to a logic high. The location of the regulator doesn’t matter i. Both sources are combined by low voltage drop diodes D8 and D9.

Since any low at the cathode of D5 will be sustained for tens of milliseconds there’s no rush to get the charge off of C8 immediately.

In addition to having the power failure detection system generating reset signals for the CPU, resets can also be generated by a mechanical switch that the user controls the big red button. This switch, if needed, would be connected to H When it goes high enough IC8D’s output will go low.

If a shunt datasjeet installed at H20 this will cause a system reset.

I’ve included this functionality because I’ve found it to be very useful for commercial systems. The “reset on BREAK” function is datashedt great benefit when one computer controls another or controls many devices networked together. Rather than having someone go to each unit and push the big red button, the central computer only needs to send a spacing condition for a few seconds and all networked controllers are reset.


It’s not expected that this interface will take the place of a real RS interface which goes on the interface board. The “poor” interface is included for simple systems that don’t make use of an interface board. Not to advance this interface as a desirable alternative to a MAX interface, but I’ve used this “poor” interface on many systems over the years and have yet to find an 80c23 device manufactured after that it won’t work with over short runs less than 20 feet.

Construction Manual This is the current draft of the manual that you get with the kit. It covers how toinventory the parts, assemble and solder the board, and the initial test procedures. These enhancements include many “hooks” that will capture and record real-time dwtasheet of interest for ham radio telemetry operations.

Monitor Hex Code This is the hex code you will need to program into an 27C and install in the socket for IC4 in order to run the monitor. Because the serial port speed is hard-coded in the ROM, there are two versions of this code: Some terminal emulators running on PCs are not fast enough to keep up athence the bps option.
