nsvtl_repository_has_VTL-2.asm (Plain text) 2022-09-25 22:09
Just a note about moving the VTL-2 68XX working files.
VTL-2_CoCo_translit.asm (Asm) 2022-09-19 20:15
This should give you vtl-2 running on the Tandy/Radio Shack Color computer 1 or 2 in a 16K or better RAM configuration. You can assemble it with lwasm from lwtools. It's a transliteration, and barely uses any of the resources specific to...
VTL-2_MC10.asm (Asm) 2022-09-03 22:09
This should give you vtl-2 running on the Tandy/Radio Shack MC-10, even in a stock 4K RAM configuration. You can assemble it with my asm68c assembler.
vtl-2_6801_exorsim.asm (Asm) 2022-09-03 17:40
Source code that runs VTL-2 on my fake 6801 simulator based on Joe H. Allen's EXORsim. Should be modifiable to run on a variety of hardware, No longer uses stack blasting, which will play nicer with interrupts. Can be assembled with my a...
vtl-2_6801_exorsim_stkblast.asm (Asm) 2022-09-03 17:34
Source code that runs VTL-2 on my fake 6801 simulator based on Joe H. Allen's EXORsim. Should be modifiable to run on a variety of hardware, but uses stack blasting, which will play hob with interrupts. Can be assembled with my asm68c. T...
VTL-2_MC10_dbg-keyecho.asm (Asm) 2022-08-28 19:58
This is a step on the way to getting vtl-2 running on the Tandy/Radio Shack MC-10. I wasn't seeing anything that I typed in, so I inserted some debugging stores to screen area to get a look at what was happening on keyboard read. Turned ...
vtl-2_6800_exorsim_clr_dp.asm (Asm) 2022-08-13 10:09
Source code that moves the variables out of the direct page and runs VTL-2 in Joe H. Allen's EXORsim, should run in the EXORciser, and should be modifiable to run on a variety of systems. Can be assembled with my asm68c. The & and * vari...
vtl-2_6800_exorciser.asm (Asm) 2022-08-07 20:41
Source code that runs VTL-2 in Joe H. Allen's EXORsim, and should run it in the EXORciser. Can be assembled with my asm68c. Be sure, after you get it running, to set the & and * variables appropriately -- something like &=300 and *=8192.
vtl-2_6800_semicolons.asm (Asm) 2022-08-07 20:34
Source for VTL-2 that has semicolons added for leader characters for comments, to be compatible with my asm68c assembler and other assemblers that allow whitespace in operand expressions
Step 02 disassembly of mbx_MM52664MBX-N_ROM.bin (Asm) 2022-04-03 21:49
Milton Bradley MBX ROM (mbx_MM52664MBX-N_ROM.bin) disassembly with some more initial definitions. Uses the 6809dasm.pl perl script, which has issues with negative index offsets in the byte range. 4 offsets need to be changed if your asse...
