The errors found - thus far - have nothing to do with the hardware interaction itself or Simh emulation of it proper; it is pure Tops10 bebaviour. <br><br>Best regards <o:p></o:p></span></p><p class=MsoNormal style='vertical-align:baseline'><span style='font-size:10.0pt;font-family:"Arial","sans-serif";color:#222222'>Volledige inhoud weergeven <o:p></o:p></span></p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
