As on many other BASIC's, the OPEN command tells the system to create a device descriptor (not sure if that's the right denomination but it's basically a handle) and assign a device to it. The first number is the device descriptor and the second number is the device. On Commodore computers, I think 0 is the screen and keyboard, 1 and 2 are the cassette recorders, 4 and 5 are printers, 8 and 9 are disks. So OPEN 130,4 opens the printer and assigns it to descriptor 130. Then you can use the device descriptor to do stuff with it, such as PRINT#130, "HELLO PRINTER". The command CMD redirects all command output to a device descriptor, so OPEN 130,4:CMD 130: LIST will print a listing to the printer. To make it stop, use CLOSE 130 (in this case). Most of the time, it's easiest to use the same number for the device descriptor as the device, i.e. OPEN 4,4. But you can use variables too. When you start a program using RUN, it resets all variables and probably also device descriptors. If you would have used GOTO 10 instead of RUN, your program that contained only PRINT#130,"BLABLA" commands, would have worked. You could have also used PRINT (not PRINT#) in your program, and used OPEN130,4:CMD4:RUN. Reading data from an I/O port works the same as from the keyboard I think. If I remember correctly it's possible to use INPUT#130,"BLA BLA",A$ but that's probably not what you want. I think there are READ# and WRITE# commands to read and write data to and from a device descriptor which makes it possible to read and write data files to disk and tape, and it's even possible to create non-sequential files on disk, but you'll have to read the commodore BASIC manual for more information about that. I hope maybe you'll get back to that after you move to your new location. That 8050 disk drive is really awesome, you could store 512KB on one side of a double density floppy disk -- I was pretty disappointed when I used an IBM PC with the disappointing 360K storage on a double sided disk -- only a third of what the Commodore at my high school could do. Also the 8050 (and all other Commodore drives) are computers that you can program: You can write a program in Assembler (sorry no BASIC) and send it to the drive, and let the drive processor execute it from the RAM buffer.

IIRC, when you run a program, it resets all the file handles ON THE COMPUTER' END but does nothing on the device end. This is not a serious problem for a printer, but for a disk drive it means the drive's end of the logical file connection is now flapping loose, connected to nothing, and the drive doesn't even know to write whatever it has in a buffer to the disk. IIRC, you can fix this (more or less) by sending the Initialize command to the drive, but that is the drive's reset command, which means if you've changed the drive's ID number in software, it's no longer changed. (Putting external DIP switches for the drive number was the biggest QOL improvement on the 1571 over the 1541, even more than the optical track 0 sensor so it didn't bang it's head to death verifying head position or being double sided or being so much faster on a 128 in 128 mode.)

Oh, one important detail about writing drive executable programs: The dual-disk units have 2 different processors. Not one to run each drive, one to run both drives and the other to run all the external communications. That makes writing software for such a drive really interesting. (A 6502 does NOT like having a second processor running at the same time accessing the same memory. To make matters more fun, 6502's need to take the first two pages of memory, page 0 and page 1, for their own purposes. Page 0 is used in a number of special addressing modes that let it use fewer memory cycles by using 1 byte addresses instead of 2, and there's couple of ways it can use an address stored in zero page and either add an index register to it or use the other index register to step through memory to pick from a list of indirect addresses. Indirect addressing modes are powerful, and like all powerful tools, extremely dangerous if used carelessly. Page 1 is the hard-wired system stack page on a 6502. This all makes both the hardware and software design of Commodore dual-drive floppy disk units a great deal of fun. There's a reason they gave up on the 1572, the never completed dual-drive variant of the 1571. They weren't able to debug the damn thing properly.)

You're make a WAY bigger deal about the hobby grade product properties than it really is. Outside of universities, this was a hobbyist computer. There were no (well, very few and far between) stores that sold this stuff back in the 70s. This was not the mid 80s when computers were everywhere and sold in Kmart and Sears. This was the 70s when nearly all of it was hobbyist and sold through mail order in the backs of magazines. This was the norm. Just a couple of years prior, like literally 2 to 3, computers were sold as box of components. The person most likely to buy this was one of the hobbyists who were only slightly behind the guys who literally bought a box of chips, resisters, capacitors etc and boards as their first computer.

The problem was, the only major retailer that was involved in that launch was Radio Shack wit their TRS-80 Model I.That was, for most people, the only computer you could walk into a local shop and but at retail, so it was, for a while, the dominant machine in the market. Otherwise, yeah, it was pretty much mail order, if you could even find an ad to order from as computer publications were a distinctly specialist thing before home computers took hold.

Even at Commodore's height, their printers weren't the easiest to get a hold of, and some questioned whether they were worth the effort. So that's why a cottage industry to make these types of interfaces existed. But it was, as you observe, a cottage industry, especially early on. And that was something Jack Tramiel was fairly proud of. He wanted to make his money, but he was glad other people were able to profit off his stuff too.

so the 4 is the device number. The 130 is the channel, which can be anything between 1 and 255, take note that typically channel numbers above 127 turn on some feature. On Commodore printers using channels with the high bit set (above 127) enables the lowercase mode which replaces 1/2 the graphics character with lower case. open 130,4 -- opens device four on channel 130 you can also use print# command to print to a specific channel The cmd command redirects the output of the print command to the channel specified. I'm sure that old line editor has a select print device command which is what you need to do to print something out with it. If you want full a full serial interface, you need an rs232 adapter that goes in the user port. You can use terminals, modems, and even printers this way. The device you are using allows you to communicate with a serial printer the normal commodore way. Actual Commodre printers do have all the PET characters in them, the Apple printers does not.

The way you deal with peripherals in commodore basic is through the open command. It's very odd. I had to learn all this crap in the 80s. This is why most people didn't own computers back then. For the VAST majority of people they were little more than eye cue (sic) tests and really complicated ways of doing very uninteresting things most people didn't need to do.

The commands for reading data back are GET# and INPUT#, for a single character and a string terminated by a Carriage Return, respectively. You use them like this: GET#x, A$ INPUT#x, B$ In both cases, x is the file handle, which you have to create using an OPEN command (OPEN x, device#, device# is normally 4 on a printer, these are more complex for a device like a disk drive which an do many more things), and A$ and B$ are string variables, needed to hold what's going to be character data. (They can hold 8-bit characters, so they may not have any meaning to the screen display subroutines of the PET.) About all you can get from a printer is a status code, and even then it requires the printer actually send them and the interface actually converts them and make them available on the GPIB interface. A lot of serial printers for the home market didn't do that, mostly because they didn't need to. You could just look at it to check the status lights. Part of the frustration with this set up probably comes from the fact that the interface isn't as smart as a Commodore printer would have been. Most Commodore GPIB connected devices (both parallel and serial versions) were at least as powerful a computer as the computer using them. In the case of that disk unit, twice as powerful as the PET, since the disk unit has two 6502's driving it, while the PET only has one.

MAYBE they have an Apple ][ with VisiCalc. 4. Packs your warranty card AND the software in a mailing envelope, and maybe adds return receipt, then sends you the whole thing along with a thank you card. 5.

And if you, like me, live in a country with a national character set you were in for yet another world of utter frustration, very rarely were you able to get a setup where all characters came out right. And when the first laser printers appeared that somehow managed to make configuration even more aggravating. I'm at good terms with most tech, except printers, and that can probably be traced back to those years.

Hmm, back when I was originally using Commodore 8-bit computers: 64 first, then 128; and a reasonably compatible printer, the BMC BX-80 (also with an interface somewhat similar to this one; and I can't remember why my dad didn't just buy us a Commodore 1525/-6 or MPS 801/-2/-3 instead, and I can't ask him now, and he probably wouldn't remember if he were still with us), we never had do do anything about baud rate. I didn't even know printers had such a thing. All these years I thought baud rate was just for modems. Ours had one wire with a pass-through card that went to the tape drive connector for some odd reason, and I don't remember the interface having its own power adaptor. I still have it but it's quite "buried" at the moment. But come to think of it, we did have some of those little switches (probably DIP) on the _interface_ to mess around with; I just never remembered them as being for baud.

OK, let's talk about those questions at the end... A modem or terminal would have normally connected to that other mystery port in the back, called the user port. An RS-232 interface to the user port is fairly simple (2 chips I think). THAT connection would be bi-directional. I think the user port is device#2. To read and write you'd use the commands INPUT# and PRINT# (which you already used). So it would be something along the lines of this: 1 OPEN 2,2 10 PRINT#2,"SENDING DATA." 20 INPUT#2, A$ 30 PRINT A$ As for decent word processors, I think Paper Clip and Word Pro were two reasonably good ones for the PET. (I'm more of a 64/128 guy.) Question is whether you can find them on TAP files. But those two, if I'm correct that there were PET versions, would be worth finding.

There were some EPSON printers that came in both PETSCII and ASCII versions the only difference being the character set ROM.

It might be able to report back an out of paper error.

Haha, "new" was the best thing you ever did with that WP program! But why did you think you needed to restart the computer, as if "new" wouldn't clear the BASIC code well enough?

I think you would need some sort of time sharing device/software to get a terminal to both send and receive from the Pet. I have no idea if that was a thing for a computer of this processing power.

Please open up the video list for your channel on your phone (in the official KZitem app) and I think you will see why you probably need to put your logo back where it used to be in the thumbnail. ☺

Yeah, it's interesting that in the case of opening and closing those channels, the program ignores what was set up in direct mode, even though strings and variables can be set in direct mode and then the program can use them as-is. And I don't even know why there has to be an "open" statement anyway, when the "print#4" ought to take care of that by itself. The same with the more complex disk commands. It seems redundant to me. Why can't they just always be open, and only receive data when you send "print#" to them? Of course you don't know that; I'm just asking it "to the air."

Dude! Your the guy I need info from lol. I'm a musician, who needs a computer that can run a DAW (digital audio workstation) The problem is, I "HATE" modern PC's and I can't stress that enough, for many reasons, bloatware being at the top of the list and the fact that modern PC's have no style to them. They just look terrible to me. I have always loved old PC's like the Commodore Pet or the Compaq Portable III system, they just look awesome. Is it possible to upgrade those to run a DAW? And also a mouse? lol The mouse is a must :D

Are you sure this program predates the computer, if it was made for the 4016 and 4032 that came out in 1979 (I used the 40xx in 1979 at school as a kid)?

Wow, adjusting an analog component like a capacitor or potentiometer for a digital setting like either baud or BPS is kind of strange.

Disk formatting has NOTHING to do with an "undefined statement" error message, ha! The "undefined statement" error message might be because there's something in there that refers to that very line that you deleted, like a goto or gosub. EDIT: But then I can't see how it would have to do with line 62020, because when you listed the program, that didn't refer to line 21. So how did you fix it?
