I've got a PDP-8A with RK05's and a TC08/TU56.
I've verified the serial port is okay (via checkser), loaded focal with the
rim loader and run both read and write tests on a RK05 pack.
I've done a restrk05 with both
diagpack2.rk05<http://www.pdp8online.com/pdp8cgi/os8_html?act=dir;fn=ima…
and
haygood-osv3r.rk05<http://www.pdp8online.com/pdp8cgi/os8_html?act=dir;fn…me>.
It seems to progress ok, counting up to the last cylinder and leaving the
AC equal to 0 when done. However when I execute the two word bootstrap for
the RK8E I hear the drive seek once and then stop at location 0031.
I've also tried a restore with the TC08 but it never even gets to the point
that the drive gets selected (the SR is 0 on entry). However if I punch in
the TC08 bootstrap unit 0 does a rewind, then goes forward (with lots of
das blinken lights), goes past quite a few blocks and then halts (this is
on a tape that claims to have OS8 on it).
The RK05 is most frustrating since it passes the rw tests (9 passes) but
doesn't boot.
I guess I'm going to be loading in some maindecs unless someone out there
has any other ideas.
Thanks,
Marc
