#108904 - Respectfully and humbly
Responding to: ???'s previous message
I probably do need to study NTSC-formatted video but I do have certain other qualifications. I am a NASA certified solderer, I have an AAS in Electrical Engineering Technology and was originally an Engineering student at UVa. Also, I printed out the data sheet on the 74HC245 and although I realize it is only basically a buffer chip, I already understood that an 8051 or some VLSI was sending bytes to the T6963C through the buffer.

Am I correct on the basic function of the 74HC245? What I have not gotten a grasp on yet is whether the parallel bus it is buffering has a hardware solution that can use the existing memory maps because I am assuming the memory maps are previous to the buffer chip.

The assembly language that is running is another matter. Also the NTSC-compatible raster display that you spoke of is something that I might need to quote for google if it would help me in addition. Does somewone have a schematic for an 80's generation IBM color or vga adapter or is there a ready made hardware device for what I need? I am investigating the link that was sent with the first reply but I can't seem to get in contact with that site yet.

My goal is to use the small multiple input (NTSC,pal,s-video, vga) monitor because of space limitations and because the monitor is already there because of the Windows GUI and there is not enough space for an LCD also.

I very sincerely appreciate all input that can point me in the right direction or simplify the task of clearing up my brainstorming approach.
