Using PIP to get files transferred. Since binary files will fail (on ^Z), Intel HEX files must be used (ASCII). Files must be less than 20kb so the HEX files need to be split.

The problem with computers is that they do what we tell them to do, not what we want them to do.
For binary file transfer using terminal devices, DUMP and LOAD were the mainstay, although they only worked as long as the contents fit into the transient area of RAM. That was fine, as you could split the large files and then join them at the other end. First pip to a hex file, then load to convert hex to binary using load. It could be then renamed from .COM to another extension. And vice versa: dump from binary to hex, then PIP to transfer over a character-only link. I’ve been doing it as a kid, so I don’t think it was super complex.
Some family member showed it to me on the condition that I wouldn’t ask any more CP/M questions that day. I didn’t even know Kermit was a thing back then, even though I had it on the disks. Must have been to fancy for me perhaps.
So it was all dumps and loads - in wonderful analogy to dump trucks working on the utilities just in front of my house… for years (no kidding). I loved the construction machinery - could just watch out of a window. For whatever reason, the adults were less than impressed by all the diesel fumes and hydraulic fluid leaks. It was pure bliss to me :) Oh, and the occasional spilled raw sewage. Didn’t mind that too much either, since big pumps and pipes were involved. How COULD one not love all that?!?! The mind boggles :)
Boy, does this bring back memories with my Zenith Z-150 many years ago. Thanks for sharing.
I used to to Kermit back in my 3M days! Good work man.
Thanks for your video!! I was trying to send a file to my Kaypro II and did it with you video's help!
Excellent!
I saw the small thumbnail and thought uuencode I was not thinking hex. Brought back good memories of using a VAX/VMS.
I have a question, that I am hoping you may be able to help me with. I am making a mega-low budget sizzle reel for a sci-fi TV show I wrote. I have been looking for a vintage computer that does not necessarily have to function. But, what I do need, is to feed external video to its screen from an old Sony handycam, So I can create an illusion of sorts... is this do-able with the Osborne? Thank you in advance! Simon
I don't think the internal monitor will accept composite video
@@IMSAIGuy bummer. I’ll keep digging.
I still have my first CP/M computer in 1984: that was designed in my home town: Santa Cruz, CA. I also have my first Computer bought in 1976: Heathkit H-8. Both still work just fine.
Isn’t the RS232 of the Osborne a +12 and -12 volts? If so, did you have to use some type of conversor to be able to use on windows ?
the RS232 to USB adapters handle this
@@IMSAIGuy Thanks!!! I didn't know that. I have one of those USB adapters but was afraid of using it in my Osborne Executive. Thanks for your video. I will start using kermit.
Yeah! I also use Tera Term. Every now and then the font changes to Japanese(?), presumably due to some rogue control characters. I have to “reset” the terminal, since I don’t know how to switch this behaviour off.
that's strange, never happed to me and I've used it a lot
@@IMSAIGuy Yeah, could be a version thing (mine: V4.72 SVN#4766). Judging by the "About" it was written by a Japanese programmer, so perhaps no surprise that it supports Kanji(?).
I can’t get this to work
github ,doc file, line 7 (missing colon?)
yes, fixed, thanks
