Great point. Does a VT100 have a pass-through serial port? Maybe the development machine was connected to a pass through serial port on a terminal and then sent command to the DEC-20 to send the files. So there would have been some sort of connection from the DEC-20 to IBM. Leased line? Packet s

One more interesting tidbit. On startup, the program sends ETX,ETX,"PJ",0dh to the serial channel. Does this seem DEC-like? I'm wondering if the development machine was connected to a pass-through serial port on a terminal (VT-100??) which sat on the DECSYSTEM-20. On 9/27/20, 8:30 PM, "cctal

Excellent! That’s a great piece of info. Not sure why a TOPS-10 command would be embedded in a program like this. The notion of filtering/delay itself makes sense but that command would make sense only if IBM had a DECSYSYEM too, no? http://www.classiccmp.org/cini Long Island S100 User’s Group

Thanks Dwight. I call it "digital archaeology". Doing a little more work on it today, trying to see what responses it might expect from the remote system. I did find specific text strings that have "CPM" in it, so my theory about the origination is probably right. I'm hoping to use some "six de

All – I’ve done a quite a bit of work with my Seattle Gazelle, and I just did some work on 86DOS.SYS (not released in source form, as far as I know) and its comparison to PC DOS 1.0 (at the code level, a very high correlation as you can imagine). Partially related to that is
