- speed up emulation - speed up emulation
- update SW401 baud rate options for Watz ROM
super19 version has the videoram at D800. This is not emulated. - update SW401 & SW402 definitions for Super-19 ROM
However, a keyclick can be heard, to assure you it does in fact work. - SuperSet support
- connect 8250 modem control lines to bank-switching for
character generation
- properly handle 32k ROM with only 16K of data.
