Looking for the file ZRQCF0 (xxdp25 or 22)

[MauriceH]

VMXAA0

If I use the DEVM = 2010
That is Bit 10=1 (bypass data wrap chan0) and bit3=1(bypass data wrap chan1)
The test is without errors
and passes tests.

Next.

As I found For some years ago I bought 3 quad cards of DEC.
One is a 4ch IO card of GTSC Model 304.
Back then could not find a manual.
Today I found it.

Also have a 128K M8059, that I configuered as Base adress.
I bought last month becouse I had no spare RAM 4116, and 1 was defective at first M8047.
Later manage to get some 4116 and repaired the 8047.

Made new config
--M8186-- --M8059----
--M7555-- --GTSC-304-
---------- ---------------

So that it completely rull's-out the M8047 cards and memory.

GTSC 304 first seemd not to work, ofcourse had to jumper JP6 so that the console at CH3 is
activated, and jumperd to 9600, also CH0 to 9600 for TU58 emulation.

Type in the Bootrap TU58 at the console.
Boot XXDP , YES a Boot.....

Run ZRQCH0.BIN.

Again

Asked a friend that has an PDP1123PLUS with RQDX3 attached a RX50 to it.
Even with no Harddrive attached he still could run the program and got beond
after the line Autoformat ? N <cr>
And got the type listing.

So Think something is wrong with my RQDX3, dammmmm

Maybe wrong PROM's?
I have 2 labeld
23285E5 (8809)
23286E5 (8810)

That firmware version for the RQDX3 by itself should not be the problem. That is the second most recent version listed here:

² gslick Thanks,

I still going strong debugging what is going on.
Hope you will still give me some hints.

Tested the device with "show Device" RT11 v53

I went back to org configuration
M8186,M8047,M8047,M7555,M8029
That is of not typing the Bootloader manualy every time....

First made my RTV53_rl.dsk bootable with program PUTR.
I used a selfmade Boot.dsk, but found out how to get the file rtv53 to boot-up with
the TU58emulator.Could not Load resorc.sav cause disk Full.

Then I could run the command "Show Device".
That is to check the vectors etc, of installed devices.
Pictures again at http://84.86.9.180/Computer/PDP1123/pictures_pdp1123.htm

-DD is Resident at 300 and 304 -> That is with TU58EM I loaded 2 Units DD0: & DD1:
-DU is Installed at CSR 172150 and vector 154
also list 8 Units
-DY Installed at CSR 177170 and vector 264 (RX02 that is running fine)
-LD Installed at CSR 0 and vector 0 -don't know what that is
-LS Installed at CSR 176500 vector 470 474 300 304 - The serial lines and are OK.
-NL Installed at CSR 0 Vector 0 - don't know what that is
-SL Installed at CSR 0 Vector 0 - don't know what that is
-SP Installed at CSR 0 Vector 110 - don't know what that is
-TT Installed at CSR 0 Vector 0 - don't know what that is
-VM Installed at CSR 177572 Vector 250 - don't know what that is
-XL Installed at CSR 176500 Vector 300 304 - I think the 2 Tape units DD0 DD1

* If I connect again the ST225 boot up RTv53
instruction
.Init DU0:
I see the LED of the HD perfect searching
Then a ?DUP-F-Size function failed.
Think because not formatted,
but test is that the RQDX is driving the HD.

Thought about the faulty Line Time Clock , that is I had befor problems with it.
After removing junper W3 M8186 the AUX switch was back on line and could swith on and off the LTC.
Probing the LTC line it is exactly 50,000025 Hz measured with a good digital counter.
230Vac/50Hz is the local main Voltage.

Asking a friend about it he manage to write a LTC test-prog.
That is I have that ILL INTER 100 problem.

At this Site "Hints on Testing a Dead PDP-11"
http://www.psych.usyd.edu.au/pdp-11/hints.html

It is mentioned some test about that interupt 100.
The Test LTC went wrong on my PDP1123 with M8186 CPU.

He manage to rewrite the test, adding 3 times 240.
For me a long time ago writing memonic's with a motorola 6802.

In all configurations with the cards I have it worked as it should.
2 CPU and diferent MEM boards, rulling out the MEM or CPU card.
The 3x 240 is a NOP because I have an older system that does not switch on or Off the LTC.
In that time normal the LTC would be activated, here it is already bij the AUX switch and alway's ON at switch.


001000 012706

001002 000770

001004 005000

001006 012701

001010 000002

001012 010120

001014 005020

001016 062701

001020 000004

001022 020600

001024 001372

001026 000240

001030 000240

001032 000240

001034 000777

Then First switch OFF the LTC
Put Switch RUN - RUN-position
1000G
ODT should be hang and NO prompt
Then LTC ON.
Should be loop to Vector 100 where value 102 it is containing.
Next 102 containing ZERO (0)
The program should now HALT at 104

Location 100 should be containing 102, if Not something is wrong with memory or LTC.

000104
@104/000106
@100/000102
@102/000000

With this test done my conclusion is for now
that Both CPU and Memory work proparly accoring this test.
Also the Line Time Clock is working proparly.
