Josh Dersch made the QUniBone MSCP driver ... eternal thanks again! He planned for an TMSCP too ... but this seems to be more difficult, badly documented and not of such importance.
Guys,
finally, finally I'm able to deliver enough QProbe2023s.
Maybe I lost some preorders, please contact me again, if necessary.
There's also a new web page describing wiring for the "Drive Activity LEDs" option on the Drive Bay Panel,
see...
Guys,
FYI: as Mark told, the new drive LEDs can be driven by both the BA23 panel connector and QBone simultaneously.
The BA23 20pin panel cable is routed throught the QProbe LED panel.
So if you like, you can wire up a BA23-QBone-QProbe combo.
And as Mark is happy now, I declare the endless...
Hi,
the UNIBUS DISPLAY register at 777570 give access to user LEDs on the old front panels.
There seems to be not much talk about it.
Is there any documented use by DEC itself, any OS, or is it just user playground?
And was it ever implemented on any QBUS machine, even as an invisible dummy...
"Sideways" is a topic. I've no idea for a "portrait" blinkenlight layout, never seen one for any other computer. And you want at least the 16 DATA LEDs in a single row, for these idle patterns => only "landscape" makes sense. Hmmm.
Hi,
I had to find alternatives for the DS8641 bus driver chips ... seems they are all gone now.
Choice for QBone is now AM26S10.
Some thoughts have gone to
http://www.retrocmp.com/projects/qbone/326-qbone-unibone-alternative-bus-drivers
which can be enhanced.
Any thoughts on that matter ...
Hi,
FYI: Josh Dersch has written new UniBone emulationen for
RS11/RF11 DECdisk
and the
KE11 EAE (11/20 arithmetic).
Now he's able to run UNIX v1 on his bare 11/20 box.
Thats's thrilling ... we're currently test 11/05 and good old '34 as other platforms.
Thanks for this work!
Joerg
Unix V1...
