I found this page two days ago - it is a Motorola document for MIKBUG and MINIBUG:includes instructions and source code for both. MINIBUG uses a Motorola ACIA for serial. MIKBUG does bit banged serial through a PIA.
http://www.swtpc.com/mholley/MP_A/MIKBUG_Index.htm I am porting MINIBUG to Tektronix 4052A/4054A assembly code (assembler program found on a Tekniques library tape). Here is the link to my thread on vcfed about that Assembler: http://www.vcfed.org/forum/showthread.php?65857-Tektronix-4052A-4054A-Assembler-program-and-TECO-text-editor On Tue, Oct 2, 2018 at 6:18 PM Torfinn Ingolfsen via cctalk < cctalk@classiccmp.org> wrote: > Also, there is this: > https://github.com/electronalan/Colormon > and a monitor in here too: https://github.com/6809/sbc09 > HTH > On Tue, Oct 2, 2018 at 10:39 PM Dennis Boone via cctalk > <cctalk@classiccmp.org> wrote: > > > > > Does anyone have source to a 6809 monitor program? > > > > > I'm looking for something I can make work in a CoCo. > > > > > Functionality I'm looking for is something that will let me read and > > > write to memory. > > > > Sources to the BUFFALO, ASSIST09 and MONDEB09 monitors are included in > > the Alan Baldwin's ASxxxx package. > > > > De > > > > -- > mvh > Torfinn >
