Ouch. Looks like that core took a serious hit.

For the record, that's a really ancient version of OS/8 Adventure.

The current (2009) is much more stable as it uses the USR to open the 
files, allowing you to move them around without causing ADVENT to crash 
(the save image has the disk locations for the files being used, meaning 
it'll crash if they move around.)


https://www.rickmurphy.net/advent/advbin.rx has a floppy image with 2.4 
binaries.

I've been to HK and I was never aware of this! Thank you for the

Not quite the same thing but I have noticed that many DEC power supplies
will sulk for a while if their overload trip is triggered.  Switching them
off and on again straight away is not enough to reset them even though the
overload is cleared.  The H7821 seems to need to be switched off for around
16 seconds minimum before it will contemplate coming to life again.  I have
come across similar behaviour with the power supplies in various other small
VAX and Alpha machines but I have not measured the exact time period
involved in any other cases.

Regards,
Peter Coghlan.

Guessing:  Check electrolytic capacitors.

This machine acts oddly. After powering it off, you usually can't power it
back on again for about 30 seconds or so, it just seems to ignore the power
switch. Similarly, if it has been switched off at the front power switch, it
will switch itself on after maybe a minute of two of being switched off. In
all other respects the machine seems fine. I have not opened up the PSU at
all, just wondering if anyone has ever seen this and might know what the
problem is?

 

Thanks

Trivia: for a while in the mid-to-late 1990s, a Google search for "computer
porn" had as the number one result one of my web pages, of that title,
containing images of computers with covers removed. I could see from the
server log that the search was fairly popular, but nevertheless I believe
that most of the people doing the search were not satisfied with the result.
