Gary, when I unload Rex, memchk returns one beep on bank 2. I didn’t have 4.1 handy but loaded 4.0 with Rex and still one beep. Reloaded 4.2 and now one beep.
But then with TS-Dos 4.2 from Rex in this state on bank 2 I loaded Line.do and CHR100.do from DL2 using an FTDI usb adapter. When I loaded CHR100, line.do now says 2 bytes, effectively blanked after the next load operation. If you want to troubleshoot this 1 on 1 outside the list, let me know. - Will Kibler > On Oct 18, 2026, at 12:00 PM, [email protected] wrote: > > Send M100 mailing list submissions to > [email protected] > > To subscribe or unsubscribe via the World Wide Web, visit > http://lists.bitchin100.com/listinfo/m100 > or, via email, send a message with subject or body 'help' to > [email protected] > > You can reach the person managing the list at > [email protected] > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of M100 digest..." > > > Today's Topics: > > 1.
