Ah, the memories. My friends and I played with this stuff back when we wre in high school and the 6502 was new. There was no open source of MSBASIC back then, so we wrote our own disassembler (in FORTRAN!), went through the MSBASIC code and figured out what everything did and produced an buildable source, which we could then modify and assemble with our own assembler (also written in FORTRAN). OSI Superboard was our breadboard. Good times.

I don't have a 6502 or the ability to justify buying a whole bunch of parts right now, but I do have an 8085, enough parts already lying around that I'm able to make something work most of the time, and the stubbornness to try following along at home even with the intermediate step of translating the entire thing to this different architecture before getting to the part where I add it to the 8085 breadboard computer and honestly? I think it's taught me even more this way! just watching these videos is educational enough, and you make the content so accessible and easy to understand, building something from them definitely gives me more of an idea of how things work and why, but taking it that one step further and getting a version of what you were showing to work with my computer? it's like I'm testing my knowledge of what I just learned, by taking what I learned and doing something with it, asking myself questions like do I understand it well enough that I can recreate it on my own 8085 computer? when I'm using different parts that have different datasheets, do I know where to start looking in mine for the closest thing to an analogue of what you showed from yours? do I understand what this code does and how it does it well enough that I can write my own version of it in 8085 assembly code? and the answer is usually yes, because your videos do an excellent job of teaching a wider concept by narrowing down on one specific instance. It doesn't HAVE to be a 6502, that's just the specific part you used, and the actual concepts are so much more applicable. since I'm on an 8085, I also won't have wozmon*, but that's okay because it doesn't HAVE to be wozmon, it just needed to be a simpler starting point than MS-BASIC, etc., etc. *I might try to port wozmon over anyway just for the practice. and to make sure everything so far is working. and also because that'd be fun, I think I guess what I'm trying to say is thank you, I'm learning so much more from these videos than I ever thought I could, and I'm enjoying every minute of it. and with these past few videos it's looking more and more like my end goal of running CP/M 80 on this breadboard thing I built myself is also possibly achievable for me someday

I also recall that the Commodore Pet had editing features that allowed you to edit any program line that was showing on the screen, but this also would have required choosing ASCII characters for the four arrow keys, and writing functions to detect those.

@@SimonBuchanNz All Ok, but MS Basic does it like this directly because of the teletype hardware all DIY computers used. Windows NT is the OS that was based on VMS, which happened several years after. The history of this is quite curious. As the concept of "file" didn't exists on Basic, using CR/LF is the obvious pick as it will always be used as output to teletype. Most mainframe/minis OS started to move to use just one char as text line terminator, mostly because of space optimization and easier management of text files. Woz did the same also to save space, but, for some reason, he picked CR instead of LF. Most of the systems picked LF, because CR was usefull as for itself to allow overstrikes on teletypes. THat way CR can still be used, and if for some reason a CR/LF gets into a text file, will behave exactly the same as LF alone.

CR/LF goes back as far as ASCII, maybe even further. There were some printing terminals that couldn't do a CR without also advancing the paper, and others, like the Teletype 7-bit models, that separated these functions.

I believe (and I can be wrong) that line editing of __ was when we used old terminal and needed to convey backspace and didnt need to output or could not output a backspace. I dont remember, I know I had dealt with stuff like that in the 70's

True. In my time coding MC on the 128 i have bitten off more than i could chew and it was mostly my keyboard. If i ever come up with building a compiler for my own language again, someone please hit me with a 2by4 🤪

That's why i always add a reset button on all ways microcontroller projects. Well, on my first telemetry controller for my solar installation i didn't, which had me try to powercycle the damn thing by unscrewing 12V cables outside in the pooring rain. That PCB got redesigned the very same evening :-)

This whole series is such a fantastic introduction to how a computer actually works. Anxiously awaiting the video where you make LOAD and SAVE do something... 😁

Interestingly, the Commodore64 originally had wozmon like features in the form of Peek and Poke. Poke allowing you to write a series of bytes to am address and peek read them. It also had a form of asm built in. If I were coding this that would have been my method. After wozmon was prepped, autoload msbasic then add functions that pass the input to wozmon as needed. After all even in MSBasic you should be able to use commands directly without making a script.

SCRTCH is probably short for scratch, as in a scratch, aka temporary data, file

The pointer for USR, the user-defined assembly instruction, GORESTART, isn't "go restart", as you state; it's that they know how terrible that code is going to be. It's actually "gore start".

I appreciate your description of some error, and some solution to fix it (5:10). Nowadays when a "bug" has been found, the blame is more of "you did this" instead of "why" and then fix the problem.

Hullo! I've been following your channel and your computer for a while now: I think I started watching around the time you built a simple video display for your computer. It's fascinating to me to watch you bring the system to life. As one who was young when all these chips were young I still find things to learn and enjoy watching you bring them to life. I have a request, if I may. I know you are busy and you have a lot to do, but you explain things so well and so clearly: could you do an 'intro to ca65' video at all? I would like to work with it myself for a project but my brain keeps bouncing off the syntax and the linker, and I can't find any 'gentle starts' anywhere online. Thank you again. Looking forward as always to the next installment!

A full physical screen for the terminal with the USB keyboard interface you did a while back would be awesome.
