/SMEMW, input/output

These signals instruct the memory devices to store the data present on the data bus for the first MByte. /SMEMW is active in all memory read cycles. /SMEMW may be driven by any microprocessor or DMA controller in the system. When a microprocessor on the I/O channel wishes to drive /SMEMW, it must have the address lines valid on the bus for one system clock period before driving /SMEMW active. Both signals are active low.

SYSCLK, output

This is an 8MHz system clock. It is a synchronous microprocessor cycle clock with a cycle time of 167 nanoseconds. The clock has a 66% duty cycle. This signal should only be used for synchronization.

TC, output

Terminal Count: provides a pulse when the terminal count for any DMA channel is reached. The TC completes a DMA-Transfer. This signal is expected by the onboard floppy disk controller. Do not use this signal because it is internally connected to the floppy controller.

/0WS, input

The Zero Wait State (/0WS) signal tells the microprocessor that it can complete the present bus cycle without inserting any additional wait cycles. In order to run a memory cycle to a 16bit device without wait cycles, /0WS is derived from an address decode gated with a Read or Write command. In order to run a memory cycle to an 8bit device with a minimum of one-wait states, /0WS should be driven active one system clock after the Read or Write command is active, gated with the address decode for the device. Memory Read and Write commands to an 8bit device are active on the falling edge of the system clock. /0WS is active low and should be driven with an open collector or tri-state driver capable of sinking 20mA.

12V, +/- 5%

This signal is used only for the flat panel supply.

GROUND = 0V

This is used for the entire system.

VCC, +5V +/- 0.25V

This is used to supply other PC/104 peripheral cards. Maximum current is 2Amp.
