Apple II Learns to Print

[@TechTangents]

A surprising number of people aren't getting that the printout was a joke. I explain it more here: kzbin.info/www/bejne/iYXXkomqhJqkY80 but it was just a cascade of different things. I even said at 34:20 that I wouldn't have added the lower text if I had know how it would be laid out on the page, I was just trying to fill the message box to see what a full sheet would look like.

By the way, the SUP R MOD RF modulator came with almost every Apple II/II Plus. Virtually no one had a dedicated monitor, and those Sanyo security monitors really weren't consumer items. No TVs had Composite in. The FCC prevented Apple from including an internal RF Modulator due to interference concerns. So the SUP R MOD was practically a required accessory. Remember that the other two computers from 1977 - the PET and the TRS-80 were B&W, with companion monitors. I think the Atari 800 was the earliest computer with internal RF out - and it required shielding like a tank!

[@c1ph3rpunk]

I'm sorry, but as a software developer, watching you go through all this trouble to acquire and install an old printer, making sure to set every little thing correctly, just to print a "SYNTAX ERROR IN 20" when trying to print something useful for the first time was pure comedy

ADT Pro always works to write disks from pc to apple II through the serial card in a pinch

[@jakint0sh]

Wait until he figures out that it works with the cassette port too :)

[@CheshireNoir]

ADTPro was my main reason to get a Super Serial Card.

[@shawnmulligan3471]

I have an Apple IIgs, and ADT Pro worked very well with that, since it has a built-in serial port. You can bootstrap the communications using PR#1 to receive the ADT bootstrap program over serial, then run it to receive the disk image and image it. Works well with Linux, and Apple II disk images are pretty small so transferring over serial isn't that much slower than imaging them on a modern PC. The IIgs also supports automatic net-booting over Appletalk, from a Mac running OS7 and AppleShare Server 1. This can give you a "hard drive" without buying anything extra, and an easy way to transfer software, since the Mac ran access the Apple II files. I have a Quadra 800 acting as the server, so I can just FTP files over to it and drop them into the IIgs' "root directory". With GS/OS you get a decent GUI with a file browser like MacOS that can access all the files on the share.

[@QuintusCunctator]

In a time where there was no Google, no Stack Exchange and (god forbid) no ChatGpt to ask questions to, reading a manual was really the intended way to learn how to operate a PC or a program. And it has two plusses over the alternatives: 1. It gives an overview of a "system" and its capabilities, not only a vertical slice of knowledge 2. It usually conveys the intent, or even the philosophy, of the author. So, while "RTFM" is a crass interjection, it is also a very valuable suggestion. Long live the manuals!

[@BradinSiouxCity]

The Imagewriter II is a pretty great printer too, especially with a sheet feeder attachment.

[@DavidWonn]

23:32 I am not certain if this works on a ][+, but on a ][e, you can embed Apple DOS commands into BASIC like this: ]20 PRINT "^DCATALOG" where you type Control+D instead of the ^D above. It won't display on screen as you type it, and you won't visibly see when you LIST, but it is there. It effectively allows the following string to be executed as if it were a command.

[@tschak909]

To send DOS commands, you must print a control-D, which causes COUT to intercept it as a DOS command. so: 20 PRINT CHR$(4);"CATALOG" will do what you want.

[@CharlesOttman]

10 D$=CHR$(4) 20 PRINT D$;"PR#1" 30 PRINT D$;"CATALOG" 40 PRINT D$;"PR#0" 50 END

[@andrewdunbar828]

Came across this a month ago. I had no recollection of having learned it back in 1979. I was trying to read random binary files off the drive. I think it's something to do with "CATALOG" not being a BASIC command but a DOS 3.3 command?

[@CharlesOttman]

@@andrewdunbar828 Correct CATALOG isn't a Applesoft command which is why when he listed the program it was showing up as "C AT A LOG" because Applesoft tried to break it up into BASIC. AT and LOG happen to be BASIC words/functions. The control-d, CHR$(4) is the escape/hook character to cause the string that follows it to be dealt with in DOS 3.3. ProDOS follows the same convention.

[@rager1969]

Oh man, I totally forgot about CHR$(4). It's also funny that EVERYONE used the variable D$, cuz that was the prototypical example, just as I was the variable used to demonstrate FOR/NEXT loops. Of course, D$ makes sense because D is the 4th letter of the alphabet and I makes sense because we are using an integer.

[@andrewdunbar828]

@@rager1969 It's actually D$ because the same character is control-D. But I'm not sure where that came from since it's ascii name is 'eot'... Well what do you know? You're also right because the ascii control codes are mapped to "caret notation" starting with "control a" being ascii 01. I never knew that before!

[@Mrshoujo]

At the DeVry I went to in the mid 1980s, students shared around a cracked copy of Print Shop which I ended up copying & sharing with a grade school class who later sent me a thank you card they printed with it. 😊 The easiest & quickest way to copy an Apple ][ disk was a program called Disk Muncher. Also you can INIT a disk with any program name. Doesn't have to be HELLO. Let us know when you start looking into Shape Tables, the Apple version of Sprites. Signs & Greeting Cards were the most used features for Print Shop. I used to create custom graphic icons for friends & print stuff.

[@DerekLippold]

That’s really the best vintage printer I’ve seen. The dot matrix I had when I was a kid was much slower and didn’t load as well. More than once it picked up the paper it had already printed and ran it through again until it jammed. It was hard to keep it in the track properly.

[@philipstephens5960]

To add some extra clarification about DOS commands. Applesoft BASIC does not implement these commands, they are part of DOS 3.3 that is loaded from the floppy disk into RAM. But the character input and output subroutines in ROM provide vectors in RAM that can be overridden, which is what the IN# and PR# commands do (they redirect input and output to the ROM on the card inserted into the specified slot). When you boot from a DOS 3.3 disk, DOS also hooks itself into these vectors, which allows it to have first crack at parsing whatever you type at the Applesoft prompt when a program isn't running. However, during running of an Applesoft program, DOS will only respond to commands being printed via the PRINT statement, and only if you precede the command with a carriage return and CTRL-D character. It won't respond to commands typed when an INPUT statement is executed. This is to ensure that Applesoft programs will run normally, while still providing a way to execute DOS commands, which as I've already said are not part of Applesoft BASIC, hence the reason why typing 20 CATALOG did not work. Applesoft BASIC simply doesn't recognize CATALOG as a valid statement.

[@RudysRetroIntel]

Having had and still have an Apple II, I use the serial card for the modem and a parallel card for my Epson FX100 printer. Since you have a serial printer, you could use the 2nd card for a modem:) Thanks for sharing

[@jakint0sh]

Hoo boy… this is hilarious and a little painful to watch as somebody who knows WAY too much about Apple IIs. So basically what you’re doing when you run “PR#1” is running the code in the expansion ROM on the super serial card, which changes the hook that the basic/monitor ROM calls to print a character to point to the super serial card’s code instead of a routine that resides in the monitor ROM that prints to the screen normally. Doing PR#0 resets this hook. This is also how the 80-column cards work, and on an Apple IIe you do PR#3 to enter 80-col mode, and PR#0 to reset back to 40 columns. All in all, I don’t blame you for not knowing, and I think it’s cool to see you try to learn how to use the machine authentically. I love what you do, keep up the good work!

[@JD-xt8cj]

I remember when I was in middle school, the teacher had me leading the class for a few minutes while she stepped out. I was trying to demonstrate one of her programs using “RUN” and “BRUN”, to no avail… then I tried “INITIALIZE” on it and erased the teachers diskette. Oops!

[@AdamKlein77]

That's when you type "home" and say "I don't know what happened! Weirdest thing!"

[@robertatkinson6864]

“INITIALIZE” would have given you a Syntax Error. The proper Apple DOS 3.3 command would have been "INIT", or "INIT HELLO" if you wanted it to run the HELLO program at boot up.

[@BollingHolt]

This inspires me to go back and look at a project I started but never finished successfully back in 2018, trying to hook up a genuine Apple 300 baud modem to my IIe. I never could get any clear answers back then on my KZbin videos as to why I couldn't make it work. When I stumbled across that jumper block and found it still set to terminal mode, I thought for sure that would do the trick, but no, it did not. I've more experience with older Apples now, and maybe six years (damn, where does time go!) later, I'll have some more experience. Awesome video!

My first computer was a ][+ clone, so this brings back some memories. I remember my favourite BASIC shortcut was typing a question mark instead of PRINT. The ImageWriter II was a colour printer. I used to print alot of greeting cards on PrintShop GS from my Apple IIGS in colour all the time. Sadly those old ribbons don't stand the test of time. The way the ribbon is advanced is with friction on a couple of foam wheels which disintegrate over time

[@OffstagePfaffa]

Hey TechTangents, let me teach an ancient Apple ][ spell of the most obscure variety. Many knew this back in the day but did not understand how it work: ]PR#1 (Select Card in slot 1 for I/O) (Interrupt) (You will then see a "?" prompt) i (Enter interactive mode) Now everything that appears on screen will also be printed, this was almost always used to create print outs of the disk catalog which was cut down to size and taped to the sleeve. I am pretty sure this is all documented somewhere in the manuals, but I never found it.

[@OffstagePfaffa]

BTW Fun fact, there is a Easter Egg in the first Iron Man movie Stark uses a similar method to boot the MK 1 suit, they swapped one step with a F# key

[@der.Schtefan]

That jumper block is actually quite cool. Most other serial solutions would require you to use a crossed cable (what old people would call a "LapLink" cable), or a crossover adapter. This one is a free adapter on the card. I remember the towers of adapters I had to use in the old days when all I had is opposite gendered, wrongly crossed cables, of the wrong width.

[@rager1969]

You don't need to put an END statement at the end of your program unless you have GOTO and/or GOSUB code (usually placed at the end of the program listing) in which case you would likely want your main block of code to end before reaching that (sequentially). Also, if you type PR#1 at the Applesoft prompt, all text that would go to the monitor will go to the printer - anything you type, any output of a command, and the text output of any BASIC program you run. So, you could type PR#1, then CATALOG and have that go to the printer. When done, type PR#0 to go back to outputting to the monitor.

[@jkeelsnc]

There was something honest and direct about Apple DOS. For a command line based system it was pretty darn easy to use. I grew up with it in school.

I never understood the reasoning behind RS-232 with 1980's computers that were never going to deal with 1930's teletypes. Yet they integrated +/- 15V or 12V signalling with a 25 pin connector. The BBC Micro got it right with 5 pins RS-423, RX, TX, CTS, RTS and GND.

[@oliverw.douglas285]

@@Drew-Dastardly A throwback to current-loop based asynchronous communications over twisted pairs. Used aboard ships in the U.S Navy through the early 1970's. I think they had a radio interface. In the 1980's the U.S. Coast Guard was still using Teletypes that connected back to Washington D.C., for sending orders to the various Stations/Bases, across the U.S. (domestically), via a leased telephone circuit. And still in-use, albeit in a limited capacity, at various phone companies, for local control Terminals. I wonder if there is an adapter, that goes from USB to Current Loop? :p

[@rager1969]

I imagine you aware of ADTPro, but just in case, it runs on Windows/Mac/Linux and on the Apple II to write disk images. I swear, it's almost like magic and it transfers/writes disks fairly quickly on the Apple II side. Using a serial connection, you can write a .dsk (and other formats) stored on the PC to a disk in the Apple II drive. It's seriously cool and you even build the first bootable Apple disk by typing in some machine code on the Apple II and run it to initiate a transfer of the ADTPro program from the PC to the Apple II's memory and execute it. Then, save it to disk on the Apple II. Going forward, you boot into that disk to transfer the disk images from the PC and write to disk.

[@jeromethiel4323]

Everybody knows the PR# commands. How many know about the IN# command? I know at least some people will know what these actually do, but they are basically print and input hooks. So when you print or input a character, it would go to the specified slot memory area and execute the code found there. So PR#6 boots the floppy if slot 6 is where your disk controller card is located. But IN#6 also does the same thing! What DOS does when it's done loading, is redirect the print and input hooks to be what they should be for normal operation. Which is why you need a "ctrl D" character for DOS commands, because DOS intercepts the character print routine to itself and looks for that ASCII code to know you are trying to do a DOS command, before passing it back to whatever. This is in no way comprehensive, and i may have gotten some details wrong, but this is basic Apple ][ functionality, and why certain things work the way they do.

My middle school hallways were festooned with Print Shopped signs for events, student clubs, and notices.

It was only one of two times I lost my composure in this manner, the second being when a human subtraction in my college dorm couldn't stop quoting from Monty Python and the Holy Grail and I set him alight in the tunnels. "Ni!" you immolated lesser-than. Stop screaming. Tis a mere flesh wound. In any case, the amount of ink used by exactly two programs in my middle school - The Print Shop, and The Bank Street Writer (the word processor of the age), could drown a small country.
