Large files transfer to the PCjr

Hi.
What is the best way to transfer large files to the PCjr equipped with a JrIDE? I personally have used CDs since I have a backpack CDROM on my system. For files <720K, I just use a floppy disk with my backpack 3.5" drive.
Can I take the CompactFlash card out of the interface, plug it into my PC's reader and transfer files directly to it without corrupting it?

I think you need to make sure your jr is off when you plug or unplug the CF card, but that should work. I have a paralel port CF reader that is hot swappable that I use from transferring downloads from my modern PC to the jr all of the time. The only problem I found is that I had to format the CF card on the jr before use. If I didn't, sometimes the modern PC could see the files but the jr couldn't.

If you are going to take the CF card and put it on another DOS system, you will be fine.

Windows is kind of a problem - it will write metadata for things like long-filenames that a straight DOS machine would not expect to be present. It is supposed to be transparent, but I still don't want Windows mucking with the filesystem that way.

I use networking for nearly everything. Even with a Xircom parallel port Ethernet adapter you can still get 30KB per second transfer speeds.

Another possibility is a parallel port Zip drive. You'll need either the PalmZip drivers which limits you to 30MB per partition on the Zip drive (but you can have three partitions) or a NEC V20 to use the standard Iomega Guest software.

SCSI Zip drives with a parallel to SCSI adapter can use standard ASPI drivers, but that's a more complicated setup.

I have a zip drive on my Jr, but these do not work on modern Windows PC's anymore, so I used it for backup only. I did not know that the Iomega guest program worked on the Jr with a V20 which is installed on my system!
I very much like the idea of networking my Jr. I have the Xircom adapter and your mTcp suite and I occasionally telnet a few BBS's. Could you please give me some pointers how to get the PCjr to show up on my home network?
I did copy a few files to the CF directly from my Windows PC without problems except the long filename issue you mentioned, but I'd rather avoid mucking up with that if there is a chance of the file system getting corrupted.

I use mTCP's FTP Server, and then I copy things to it using FIleZilla which handles recursing down directories and so forth. It can take all night to copy 1G over, but it does work.

OK I'll give it a try. Should be fun :)

The FTP server works great! That is probably the easiest way to do the file transfers...
BTW, the Iomega guest program did not work on my system. All I got was screen corruption and a hung system...

Do you have a NEC V20? (I thought I mentioned that GUEST requires one.)

I do.

Is there a way to have the PCjr show up on network discovery under Windows 10 rather than go through FTP?
