| The SB8010 
			is a highly 
			versatile SBC  comprised of a Z-80 microprocessor, 4 general purpose 
			28 pin sockets for byte-wide ROM and/or RAM chips, a Z-80 CTC 
			counter-timer, and a serial I/O port (UART) using Intel's 8251. A 
			bootstrap option is provided for loading an operating system into 
			main memory using an on-board PROM. 
			  Key Features
				On-board memory can be mapped in various ways to match the 
				memory chips selected. The mapping options are accomplished 
				using a PROM. The user may install his won PROM if a different 
				mapping is desired. However, the  six mappings provided should 
				satisfy most users 
				PricingThe serial I/O chip uses the counter-timer chip as the clock 
				source for both receiver and transmitter to that baud rate is 
				programmable by software. RS232 buffers are provided for all the 
				serial outputs and inputs. In an interrupt driven system, the 
				serial chip (8251) uses the CTC as an interrupt controller, 
				enabling the serial chip (8085 peripheral) to benefit from the 
				sophisticated Z-80 interrupt scheme.The CTC can also be used as an interrupt controller for 
				external events as well as a general purpose counter and / or 
				timer. See also the SB8466 Multi-Mode Parallel 
			Interface card, the great Add-on to this Z-80 SBC. 
			  SB8466 Parallel Interface Board 
				
					| The SB8466 Multi-mode parallel interface 
					provides STD bus systems with six 8-bit parallel I/O ports, 
					configurable into a combination of input and output ports. 
					The SB8466 supports a variety of operating modes, including 
					simple, strobed with interrupt, bidirectional and DMA. Three 
					ports can be configured with open open collector output 
					drivers, two ports are fixed input with buffers and resistor 
					pull ups, one port has bidirectional drivers. It is easy to 
					adapt and use with any other 8 bit microcontroller system. 
					
					 Key Features
						Single +5V operation48 lines of I/O plus handshakesUseful for driving panel switches and indicators.DMA modes for high speed block data transfer between 
						STD bus system.Flexible interrupts structure.Inverting/none-inverting, active/open-collector 
						drivers can be installed.Pin out compatible with OPTO-22 I/O module racks.Easy interface and adapt to any 8bit 
						Microcontrollers (8051, PICs & Z80) Pricing
