Hi all
I updated my Cyclone variants, both Cyclone II and Cyclone IV to (finally) be able to use all interfaces in CP/M CP/M 3 You can now boot with any interface as active, giving you the option to use different baudrates (see rom file). Also the baudrate of serial interfaces can be set within CP/M. See the 'Whatsnew" file.
CPMega-88 has been updated with RTS handshake. (this also involved a PCB update) The major shortcoming of this board was that there was no way to use the (only) serial interface for file transfer. This is now fixed. A i8080 version of download.com (originally by Grant Searle) has been included and this works well.
I also changed the disk system. It now uses one similar to the Cyclone versions, i.e. 254 mountable volumes. Additional system tools are added: GETSYS, PUTSYS, FORMAT as well as an i8080 modified version of MOUNT.
All files are available on my builderpage
Have fun
Rienk
