Here is a link to a set of screen shot of the autoexec.bat and config.sys for an IBM PC I came across today and the boot screen when these are attempted without the networking hardware attached..
https://www.vintagecomputer.net/IBM/5150/5150_DEC/ Specific to IBMPC to DECNET networking...anyone worked in this environment? Not me. I don't have the D drive that fails or the network, but I am curious what I would need to make this work. Maybe I can put something together. Anyone using a Digital Ethernet Personal Computer Bus Adapter today? The A drive had a jumper between 4-pin connectors 10 and 13 but it was not functional and I replaced the drive entirely. Not sure if I needed a 720K drive attached externally or something in order for the 5 1/4" drive jumpered this way to work. I have a pic of this there too. Weird. Thanks in advance. BIll
