I used mine for more than 10 years and have no idea how long
or much the previous owners used it. Never a problem. I kept
the KLESI module to use with tape drives after I gave the disk
away. Now that was a truly weird system. same controller but
the cable went one way for a disk and the other way for a tape.

They worked as long as you didn't spin them down or try to change the

Hi, Bob,
Perhaps.

Ah... that may be part of it. I never did. I loaded one removable
pack and never swapped it out.

Right.
I have a different 11/725 now (long story but I screwed up and the old
one went away at a friend's company when they were purchased and shut
down)... I've had that replacement 11/725 for 10 years but it didn't
come with a removable pack so I mothballed it out at my farm. I have
only gotten a couple of removable packs in the past year and have not
been able to spend time fiddling with it, but it's going to be a full
cleaning and overhaul (dust, fans, PSU test, TU58 roller...)

No fun.

I didn't want to bung up my only drive, but if I had 2, what about
this? Put a foam or rubber wedge between the head arms of the
removable pack (to keep them from thwacking together) and defeat any
sort of interlock or removable cardridge sensor (I think there's a mag
sensor at one corner?) The idea is to make the drive think there's a
pack loaded. It might take doing something with a real pack housing
and removing the platter in case the lower mass screws up the spin
rate.
Of course, if the internal drive electronics lose their mind because
there's no signal coming from the removable pack heads, then it will
likely go into Fault and not work. This is all just speculation on my
part but I can envision ways that it doesn't keep the drive
electronics happy.

Same. That's what really slows me down - not wanting to start without
a single idea of how it works.
And then I think of how much work it would be to convert one of my
COMBOARDs from a 3rd-party comms controller into a 3rd-party disk
controller (I have full schematics and specifications and source for
all the COMBOARDs so that's not starting from zero) but between
designing and writing new firmware and writing drivers for every
possible OS (RT-11 and VMS at the absolute front of the list), before
I even get started, I just find something less insane to do.

It was Wyse terminal emulation. Wyse totally dominated the dumb serial terminal market in my part of the world by then, and OSes like SCO Xenix expected Wyse terminals and their quirks. An emulator for the DEC terminal the Wyse claimed to emulate would not work well. For us that was the appeal of stuff like JRiver ICE.TEN and WRQ Reflection -- perfect Wyse emulation. Oddly enough Reflection is still around. WRQ was bought by Attachmate, who bought Novell, and who were bought by Micro Focus -- so for whom I now work. -- Liam Proven - Profile: https://about.me/liamproven Email: lpro...@cix.co.uk - Google Mail/Hangouts/Plus: lpro...@gmail.com Twitter/Facebook/Flickr: lproven - Skype/LinkedIn: liamproven UK: +44 7939-087884 - ČR (+ WhatsApp/Telegram/Signal): +420 702 829 053

I can't imagine this version of Reflection is that hard to find though. It was everywhere back during the days of use, like wordperfect 5. If there are requests I can image and post on my website for educational purposes only. ProCom was my go-to program then, but I also used Reflection. All these programs worked the same IMHO most all had DEC terminal emulation Bill >

So, more recent versions lost the ability to interact with older (niche now) hardware ?

Re: Whence 556?
On Sat, 2 Jun 2018, Chuck Guzis wrote: So 200 and 800 are nice decimal multiples of 10. But 556 doesn't fit that pattern--it's not a "nice' number, being the product of 4 and 139 and doesn't correspond to any computer-related characteristics that I know of. It's not metric. So why 556 and not 400, 512 or 600? Just a guess, but 556 kHz is 5 MHz divided by 9. Christian
