PDP-8 "Dumprest" experience?

[Philipp Hachtmann]

Hi folks,

I am just beginning to use Dave Gesswein's DumpRest from
ftp://ftp.pdp8online.com/software/dumprest/.

I successfully restored TD8-E DECtapes with it. That enabled me to 
install OS/8 on RK05 etc.

I also (roughly) integrated the dumprest utilities into OS/8 (I can 
start them and they reboot OS/8 back to the monitor). And they now use a 
separate high speed rs232 port to connect to my PC (as my kermit does).

When I use restrk05, I always get a checksum error. I just have read one 
RK05 disk - three times. What I get is always the same checksum error 
printout with the same checksum. And the generated files are identical 
as well. I can also successfully run them in SIMH.

So what's wrong? Does anybody has a clue? Is that a known problem?

Best wishes,

Philipp :-)
