[Battle of the Ports]

Sculptured Software would've been a good choice to go with too.

[group of multiple line deletion in a basic program]

GW-BASIC uses DELETE that way too.

(removed due to redundancy)

[POKE combo]

It's probably doable but it would require a lot of work.  Look at something like GPLE, though - I think that does pretty similar to what you want.

[GET K$ usable with CAT command in a program?]

It's going to require opening the directory as a file, but it can be done.

[blinking cursor 80 column mode on 2c]

POKE 2043,255 (note this ONLY works, afaik, on a //c)

[how to list files horizontally on 2c]

Under ProDOS-8, you can OPEN a directory and READ it and get the same data a CATALOG would give you.

 

You can then parse that into a columnar format.  I could prolly bang something together but it'd take some time.

[Battle of the Ports]

The Bang Zoom dub pronounces it correctly.

[Problems running Tandy/PCjr games with exclusive features]

I think PC-BASIC might not be accurate enough if stuff uses machine-code subroutines or similar, as some early BASIC programs did (e.g., "In Search of the Most Amazing Thing" does so for graphics decompression).

 

The Tandy version 3.20 GW-BASIC is probably good enough.

[New Infocom style adventure - The Locked Room]

This particular game uses Infocom's Z3 interpreter version K.  He's probably using something like InterL to interleave the code and combine it with the interpreter to create a disk image.  It also says it was built with Inform 6.36 and the PunyInform library.

[Problems running Tandy/PCjr games with exclusive features]

Is it Tandy's BASIC you're trying Peanuts Picture Puzzlers with?  That's compatible with Cartridge Basic.

[where is the BASIC.SYSTEM file in Copy 2 Plus 8.1?]

Copy ][+ never had or needed BASIC.SYSTEM on the disk to my knowledge.

 

1.1 was the most common version of BASIC.SYSTEM and was found with system disks for ProDOS-8 1.1 through 1.4.

I think Universal changed their name to Aruze, then back to Universal.

 it's almost 2,222 miles or less if you take I-81 S from Maine to Texas. it takes about 33 hours to drive down.  Anyway, Hope you can get cart dumped if available..

81 doesn't go through Maine, it starts at the Thousand Islands in NY.

Popeye was the one that wound up with Namco.

 

Mr. Do! was Universal, which changed names a few times and is back to the old name and logo.

[Lode Runner™ for Atari 2600]

It's there, yep.  The game disk won't let you edit it, but I wrote an editor of my own some years ago (this is where the graphic above is rendered from).

[trying to copy from a 3.5 to 5.25 but no luck]

Yeah, the IIgs is quite backward-compatible.

 

My experience: 6.x or 7.x is the ideal Copy ][+ for putting on a 5.25" disk (it will fit), and 8.x on 3.5".

[trying to copy from a 3.5 to 5.25 but no luck]

Your 3.5" disk has 1600 blocks (800 KB), 5.25" has 280 (140 KB).

 

You can try to copy the files.

[trying to copy from a 3.5 to 5.25 but no luck]

ProDOS will complain if there's more than one disk with the same volume name. You'll need to rename one of them.

[an autoload program for CAT command?]

Format a disk with ProDOS, and copy the files PRODOS and BASIC.SYSTEM to it.  Then:

]10 ?:? CHR$(4)"CAT"
]SAVE STARTUP

[Again, I call the video game crash "bullsh*t".]

I feel it was more of a market correction than a crash.
