So I've been fighting with my parallel port Ethernet adapter for quite awhile. Not sure if the adapter is bad, or if the jr is too slow to keep up with modern technology. So in the meantime I needed a way to transfer files to my jr from my Linux box that didn't involve Ethernet...and also not 5.25&q...

I was thinking about this NIC in the modem slot again. The ability to send and receive raw packets (packet driver) might not be the best idea. While it is excellent for usability with existing applications, I have been having a lot of issues with a parallel port NIC and said applications. I'm not su...

I was also successful in installing and booting DOS 3 on the SD card adapter: https://www.amazon.com/gp/product/B00DGNYXQ0/ref=oh_aui_detailpage_o08_s00?ie=UTF8&psc=1 I also used a standard PATA IDE cable along with this 44-to-40 pin converter: https://www.amazon.com/gp/product/B00006B8C2/ref=oh...

Thanks Hargle. I have no problem using DOS 5, and after posting I realized I should check...I might have DOS 5 360k floppies around here somewhere...I need to check on it. Is everyone using PC-DOS 5...or is MS-DOS 5 also known to work properly with the memory detection patch? Also, will DOS 5 load W...

Hi Guys, I just ordered a PE3-10BT, but without a power adapter, so I need to order one. Would someone be able to measure the barrel jack to confirm the proper size? If so, I can order the adapter before the PE3 arrives...otherwise I'll wait to measure the jack. The manual doesn't have any informati...

Sorry for a tangental question, but how do you connect a DOM to a modern machine? I purchased a female to female IDE adapter. I plug it straight in to my IDE cable on my desktop box. I cut/bent the key pin on the adapter on one side since my desktop IDE cable has the pin hole filled. https://www.am...

I've ordered a 360k drive. Will write some DOS 3 floppies and boot them directly on the jr in a week or so.
Between all the DOMs I have, that should be able to get something up and running.

Have others tried loading the OS on the drive from another x86 machine, then plugging it into jrIDE with success? I wonder if there were any address translation issues in the jrIDE, perhaps the data isn't being accessed the same. If that were the case, loading the OS on the jr might work. I've been ...

I don't think power is the issue. Gave the DOM a separate 5V supply from a bench DC supply...same behavior.
If the patch isn't working as expected, is there any printed output on the screen after "Press [ESC] to enter boot menu" (or whatever that message string is)?

So I ordered some other flash modules and I got one that gets detected. It's a KingSpec 16GB DOM. I am still waiting on the 40-to-44 pin converter for the others. I formatted the DOM as follows: C: 2GB D: 2GB E: 2GB F: Remainder of 8GB Then I installed MS-DOS 6.22 to C:, did the patch to the boot se...
