That does look absolutely great!

We have highs in mid 80s and lows in upper 50s lower 60 right now. A little high.. It is dry now but was wet a lot earlier in the month. So a little more rain than usual and slightly higher temps.

I was in Arizona this summer in the Phoenix area. We had a stretch of 10 days or so where the temp exceeded 110 F. We had some tremendous monsoon storms mixed in with the tremendous heat. There is definitely a warming trend in the Sonoran desert. 116 F is nothing to sniff at. Yes, it's dry heat but 116 is a bitch no matter what. We had many days around 113-115 this summer. I am back in PA now surrounded by trees (and Commodores. There has been s lot of rain this year. This is a big El NiƱo year. This fall is just beautiful so far.

With your X1571 format besides conquering REAL HARDWARE WORLD (Earth) we could also conquer EMULATOR WORLD (Simulated Earth)! Confession: we like Pinky And The Brain here...
I see it as a needed component but apparently the rest of the world doesn't. That may have something to do with the relative rarity of actual 1571 drives, which were interesting/marketed only to the apparently underappreciated user base of C128 users.
** VICE 2.2 (what I use) and VICE in general I suggest strongly is lacking if it doesn't handle documented drive characteristics.
I normally use my real hardware, so I guess no need to resurrect that code for VICE on my behalf.

I think you do not go through the loop an extra time when you use UNTIL like this. 10 OPEN 8,8,8,"INTERESTING.TXT":DO UNTIL ST:GET#8,A$:SP=ST:PRINT A$;:LOOP:PRINT SP:CLOSE 8:END will print the seq file to screen and then print SP. It will read 64. It would read 66 if the program ran through one extra time. The program will not LOOP if ST has any value other than 0.

Unflippy could be good for a self booting disk that has MFM format on flip side, setting it up to be read or written to, maybe a little disk based MFM access system. After I thought about the spin backwards thing I tried to find an example of someone else doing it. My forays into hardware alteration are few and far between. The guy who wrote ummm... I think it was called DOS 5.0, mentions it but doesn't say he did it. That's a package that can read and write MFM disks on a 1541 with hardware alterations.

Usually I find the value of ST is either 64 or 0, so IF ST THEN CLOSE (or whatever) (FILENUMBER). The value of ST will indicate EOF for PRG files too. Not sure about USR and DEL files. The 66 value seems good for determining where to add new data to the end of the file. I have never used it though, or even noticed it. ST is a system variable and will not accept values from user input. At least not from this user. Short program to list SEQ file in 128 mode.
10 OPEN 8,8,8,"INTERESTING.TXT":DO UNTIL ST:GET#8,A$:PRINT A$;:LOOP:CLOSE 8:END You could add S,R after the filename but those are default parameters so left out if just reading a SEQ file.

Not likely we would find a magic cable that drains the chroma AND luminance out of every other character... at first I thought it resembled bad combining of luma and chroma into the video input, but those black letters...

Have you tried a different cable?

Yes, accessing the back side on the 1571 10 OPEN 15,8,15,"U0>M0" 20 PRINT#15,"U0>H1":CLOSE15 U0>M0 because it has to be in 1541 mode... Maybe a 1541 could be made to spin backwards to read them; flip disk and read side b by spinning disk backwards. data comes in the correct direction... How hard can it be? (Having never heard of it being done myself...) and no... I haven't found a working method. I use these to keep my 1541 disks the same while using the second side without notching. I don't have a disk notcher and have bunged up several disks with hamhandedness or plain not watching what I'm doing.
