New release of IBM 360/30 code for Digilent Spartan 3

Having finally got back onto this project a few months ago, I have prepared another release of the code from my IBM 360/30 emulation project for the Digilent Xilinx Spartan 3 board. The main differences from the previous release are: * 64k storage in external static RAM * 1050 Console typewriter/keyboard implemented using the serial port * Main storage initialisation from a file stored in the flash rom (This can be generated from a Hercules PCH file) * Lots of little bug fixes The main limitation is that the 1050 is the only peripheral available. There is a known bug: The first character output by the 1050 on each SIO is duplicated. There are probably lots more hiding. Everything is available at http://www.ljw.me.uk/ibm360/vhdl/ Future tasks: Implement printers/readers/punches via multiplexor channel Implement tapes/DASD via selector channel and flash disk -- Lawrence Wilkinson lawrence at ljw.me.uk The IBM 360/30 page http://www.ljw.me.uk/ibm360
