Vintage Computer Data-Backup , example with DEC PDP-11/23 running RT-11 ( 1987 )

Video #5 : Vintage Computer Date Backup may be become very importend. Computer oldie don’t have interfaces based on current used technology like USB or network connection –BUT– all have a serial console interface. Using the KERMIT program, available on most of all computer platforms, is a very good way to make a full data/system backup. In this example, I used the KERMIT program to create a full RT-11 system backup on W-XP. The KERMIT program I used on W-XP is the try & buy K-95 from columbia university. ( I could ‘t buy this software until now, because the link to the URL is not working ) This video illustrates all necessary steps to get full system backup from a 5Mbyte RD50 saved on a flsh ram memory, usage only ~4% !

I got some computer during my time as an DEC employee and from the Computer-Museum in Munich. More details can be obtained from my homepage if you want.

That’s really interesting. It’s good to know there are people still interested in vintage computers. I would love to see one of those personally. Where did you get yours?

Restoring is just the other way round . If you have to restore the entire system, you must have another bootable device ( in my example, a RX02 floppy drive ) running kermit on it.

Besser schlafen nicht unbedingt, allerdings könnte ich nun RT-11 auf mein Handy kopieren und drauf schreiben: “RT-11 inside, but not driven”
) Einen solchen SD-Karten Konverter zu bauen wäre möglich, denn es gibt ja schon Parallel/USB converter und Parallele interface für den Q-Bus gibt es auch, Aber ich bin zu alt für so was … ?…

WOW jetzt kannst du bestimmt besser schlafen;-)
jetzt wo du RT-11 gesichert hast, kannst du vilelleicht mal einen CTI-Bus-zu-SD-karten-converter bauen. Um die RD50 festplatte nicht weiter in seiner lebensdauer zu beeinträchtigen.
