The revival process of the 11/750 continues. The power supplies is working
good and then I started testing the actual machine. But that was not a very
smooth journey to success. I have in total at least three complete CPU
board sets and just after quite a lot of board swapping it got running (I
I had error like:
* Bright red error light
* No response at all on the console
* %C microverify error
* %O microverify error
* An hexdump prompt which non like above bot still not correct.
Finally I had the
%% which meant that it passed microverify.
Then I used the (second) RDM module (the first one had RAM error) to run
the DPM and MIC test which passed.
The I ran the "Hardcore VAX instruction test" / TU58#7 which also passed
BUT the Cache / TB diag, TU58#5, give me this:
@?ECKAL -- VAX 11/750 Cache/TB Diagnostic
I am running a BE-S198Q-DE tape image.
Anyone has a listing or description for the ECKAL diagnostic? Is there any
know incompatibilities with certain revisions of boards? Or known bugs?
The machine manage to boot the console tape so I get the BOOT58> prompt.
But I am not sure if that indicate that it is indeed working or not.
So, some help with the Cache/TB diagnostic would be very much appreciated.
I can?t really tell if this is on-topic, but there?s [no|some|much] shame
I have a Visual Basic 4 application that I need to run on modern 64-bit
hardware I can do this in a VM, but I really need this VM to be wicked
small, like under a gig. The smallest XP VM I?ve seen is 600MB (which might
be good) but XP is becoming very hard to source these days.
I am bummed that there doesn?t seem to be something like vDOS or DOSBOX for
VB applications. Or? maybe there is?
Does anyone have any suggestions on how I might go about doing this?
VB4 is what, mid 90s? How about you upgrade the code?

To be able to use my parallel port programmer I keep an old (by modern
standards) machine running with Windows XP on it. It is an Abit KV-85
motherboard for AMD processors. In recent times I have had a couple of DIMMs
fail on me.
I am not sure if this is just coincidence, that I have had a couple of bad
DIMMs, or if the motherboard is damaging the DIMMs.
It uses a cheap generic PSU, I checked the PSU for voltage and ripple and it
seemed OK, I also checked voltage and ripple on some of the power pins of
the working DIMM, they seemed OK too (ripple about +/- 20mV), but other than
that, are there any other things I should check?
That is spectacular! thanks for sharing it!
that last picture is why you needed the E with both backplanes .... to
hold all the i/o for all those devices!
