That's a great flow diagram Tez - however, I do think there are not nearly
enough arrows pointing upwards ☺

Yep, I've already checked out the rest of the voltages thru the machine. The AC
inputs are correct, +15 is good, +5 is a little high at 5.5v but workable and
I'll tweak it later, -5 is good, etc.

We do make a LOT of stuff available that is put up via ftp (privately, by
myself or a few others), but it's always been available via http not ftp.
It is also possible that many of the people who have their website hosted on
the classiccmp server are making stuff available via ftp, and I wouldn't

Hmm. I thought classiccmp.org used to make stuff available to the
world via FTP. Have you dropped that, or am I ha
Yes, anonymous login is disabled because the sole reason for FTP is for
the various authors/maintainers of classic/retro computing sites which the
classiccmp server hosts. Each website owner/author uses FTP to maintain
their website on the classiccmp server.

Thank you for the link.
Is "anonymous" login enabled on your FTP server?
Or do we require a login before we can access the site?

You could write it.
The paper tape emulator there needs no drivers. I have one, and it works
incredibly well (on HP2000 as well as every other environment).
As to the ide disk emulator... there

Before you dive into the brick (sounds painful!) check that the +15V DC input
is present and correct. Unlike
the +5V units (H744, etc) the H745 needs both the 20V AC

Anyone got a user manual for the above? Online or willing to place it
online? I have a couple of those, working, and struggling to figure
out how to change the setup. I've got as far holding the setup key,
then ctrl-8 to get it to print the current settings, but can't figure
out how to change baud
