WHY SETTLE FOR LESS- THAN A COMPLETE 6800 SYSTEM MEMORY- All static memory with selected 2102 IC's al lows processor to run at its maximum speed at all times. No refresh system is needed and no time is lost in me- mory refresh cycles. Each board holds 4,096 words of this proven reliable and trouble free memory. Cost- only $125.00 for each full 4K memory. INTERFACE- Serial control interface connects to any RS-232, or 20 Ma. TTY control terminal. Connectors pro- vided for expansion of up to eight interfaces. Unique programmable interface circuits allow you to match the interface to al- most any possible combination of polarity and control signal ar- rangements. Baud rate selec- tion can be made on each individual interface. All this at a sensible cost of only $35.00 for either serial, or parallel type PROCESSOR- "Motorola" M6800 processor with Mikbug® ROM operating system. Automatic reset and load ing, plus full compatability with Motorola evaluation set software. Crystal controlled oscillator provides the clock signal for the processor and is divided down by the MC14411 to provide the various Baud rate outputs for the interface circuits. Full buffering on all data and address busses insures "glitch" free operation with full expansion of memory and interfaces. DOCUMENTATION- Probably the most extensive.and complete set of data available for any microprocessor system is supplied with our 6800 computer. This includes the Motorola programming manual, our own very complete assembly in- structions, plus a notebook full of information that we have compiled on the system hardware and programming. This includes diagnostic programs, sample programs and even a Tic Tac Toe listing. POWER SUPPLY- Heavy duty 10.0 Amp power supply capable of powering a fully expanded system of memory and interface boards. Note 25 Amp rectifier bridge and 91,000 mfd computer grade filter capacitor.
