erro bug 06h MPC60

who,s got the service manual i got the message

...sorry, but a bug of the type 06h caused all memmory to be lost..

i,t happens on start up

The service manual won't tell you what causes this.

For the most part the "hardware system errors" can be found here:

http://www.mpc-forums.com/viewtopic.php?t=15963

Error 06H is a "reserved exception" type.

Most likely to happen as a result of the 80186 CPU trying to process garbage instructions ... as a result of the EPROM'S and related memory interfacing circuitry around same malfunctioning.

Tell us all a little bit about your MPC60 ...

What OS was it running before the crash ?

How much sampling RAM is installed ?

SCSI option fitted ?

i got the mpc60 MK2 os2.12 no scsi no extra memory i got an other one(working fine) mk2 OS 2,12 with extra memory

i replaced the erpom,s of the good mpc with the error mpc,and the error mpc eprom in the good one...can you follow but the result stay,s the same

so the eprom,s are fine,

Ok this is a good sign for the EPROMS condition.

If you are tech savvy enough to pull and swap EPROMs then:

A possiblity of failed battery back up to the CRAM ( NVRAM ) can cause weird stuff to happen ( some times ).

As a start, with the power off and disconnected, you could momementarily short both sides of the CRAM ( NVRAM ) battery ( type CL2020 ) on the main CPU board.

If this doesn't help then check the power supply is delivering clean and correct voltage to all intended areas.

All I can think of right now.

i put the hole CPU board of the error MPC into the good MPC

but with the same results,its still give the 06h error, so something wrong at the cpu board

i also pulled the backup battery out en shorten the pole(should leave it shorten and then put the mpc ON ore just shorten a moment when the MPC is OUT,should i mayby replace it with a new one,

thanks for your help

David

could the main processor be default n80186-10 intel

Ok ... using a known working chassis, voice board and power supply is a good idea.

So ... good idea...

Yes ... indeed.

Old Intel 80186 CPU's of this vintage and type don't fail all that often ( but in certain circumstances they can ). Components around the CPU though, like memory and related CPU<>memory interfacing can fail with time or exposure to bad operating conditions.

Replace the battery with a fresh one as a matter of course.

The main processor for an ASQ10/MPC60 was first designated as a:

MBL80186-10 ( FUJITSU SEMI-CONDUCTOR 80186 running at 10 mHz )

<http://www.cpu-world.com/CPUs/80186/Fujitsu-MBL80186%20(PGA).html>

A few ASQ10's and MPC60's that have passed my bench have had:

IAPX80186-10 ( Intel 80186 running at 10 mHz )

<http://www.st.rim.or.jp/~nkomatsu/intel16over/i80186.html>

is the PCB board of the ASQ10 precise the same as the PCB board of the mpc60,(mayby by a asq for repair) also could a swap the Bad MPC PCB intel processor with the good MPC intel processor

Indeed you could

As far I remember the mainboard in both ASQ10 and MPC60 are the same.

The MPC60 has an additional boards for sound generation, pad interfaces and such.

If such is the case then you drop the ASQ mainboard into the MPC60 and then swap the MPC OS ROMS alone; not having to worry about exchanging the CPU.

Maybe perform some more investigation to confirm what is really going wrong with your MPC60.

All of this board swap/echange stuff seems a bit drastic.

i gonna swap the intel, but i think that,s not it, cause once i put 3,10 in and then he did it good (for one exeption i could not load the floppy drive he sees the pgm and snd, but when he say load,after you push load it ..then he says there isnt a floppy in the drive)..... put 2,12 in and error again put 3,10 in and error again,(error 00h) tried several times, but it only happend once

iam also ,gonna let a technician look at the pcb board ,

THANX, David

Sounds like a continuity problem some where on the mainboard.

Perhaps the solder needs re-flowing around certain components.

Good luck with tracing down what ever the fault is.

Let the group know what it turns out to be.

Rohan.

i will get back on it

Hi Fellas,
What do the numbers indicate below the N80186-10? Do I have to source a chip with the exact #’s. This is a CPU out my MPC60II that I want to try and replace, if possible. I should be able to swap it with 1 of the other 2 mentioned in this thread too right?

Thanks
heres a pic

@cuba7000: Did you ever fix it and find down what the problem is?

I've been getting the same code for the past couple months too - 06h.
