After attaching an external power supply to my TK70 (since I don't
have the sled with connectors to the VAX's power supply, and didn't
know where to solder power cables to from inside the empty bay), and
installing the TQK70 into a Qbus slot, I can't get the system to even
recognize the TQK70. Nothing lights up on thee TK70, although both
LEDs on the TQK70 are lit. The cable is connected the right way.
The CSR on the TQK70 is set to 774500, and the jumpers are connecting
the bottom two of the three rows of pins on the drive-select jumpers.
I've tried inserting the TQK70 into various slots (including upper and
lower, since I understand that grant continuation follows a serpentine
pattern.
When I do a show qbus command, the TQK70 doesn't show up:
>>> sh qbus
-20000200 (761000) = 0000 IDV11A
-20000202 (761002) = 807F
-20000204 (761004) = 0000
-20000206 (761006) = F9FD
-200002AC (761254) = 00C0 DTCN5
-200002AE (761256) = 0000
-200002B4 (761264) = 0020 DTC05
-200002B6 (761266) = 0000
-200002B8 (761270) = 0020 DTC05
-200002BA (761272) = 0000
-20001F40 (777500) = 0020 IPCR
Any thoughts/ideas?

Hey ya'll... does anyone have an online/pdf/html/etc version of the C64
command list or (better yet) the User Manual? I have a working C64 it good
condition along with the 1541 floppy and a printer with interface. Nice
setup... but could really use a PC with the old fashioned 5.25" floppy
drive. *Sigh*

Can someone please tell me what I'm doing wrong?
I have two VaxStation 3100/M76's that refuse
to respond to the keyboard!
After the POST, I get the usual error messages for missing
disks and missing AUI adaptor. I then get the ">>>"
prompt, and that's it.
I'm using several LK-201's, and they all behave the same.
Both VaxStations behave the same.
Is there a special 'dance' that I have to do before
the VaxStation responds to the keyboard?
Are they really fragile, or something?
Thanks!
Jeff

Hmm, I wonder who is adding 4 to the error address: the machine check generation
logic in the CPU or the machine check handler in the firmware...

Try reading the IP and SA registers with EXAMINE commands:
>>>E/P/W 20001940
>>>E/P/W 20001942
If instead of numbers (values read), the console responds with a message to the
effect that no device responded to the read, it means that there is something
wrong with the TQK70 board. It has nothing to do with the power to the drive
since the controller must respond to reads of its IP and SA registers even if
there is no drive at all. Grant continuity problems also won't affect the
ability to read or write registers, since the device can still act as a slave,
it needs a grant only to do DMA or send an interrupt vector to the CPU.

I recently had dry wall and laminate flooring installed in the basement.
Since then, I've been getting shocks when I walk into the room and touch
anything.
Any ideas on reducing/controlling the static?

Hi
One other thought. Take some liquid dish soap and
delute a couple of spoons full into a bucket. Mop
the floor with this, without rinsing ( just let it dry ).
This should also help some.

Hi
Don't wear shoes. Humidify the air. Get an ion generator.
