LEDS, camera, ...
gregory.g.thain
My pc532 is almost working! After many months of obtaining parts,
tools, a diploma and gainful employment, I find myself with my pc532
fully soldered. At power-on time, all 4 LEDS light, but nothing on the
terminal. Any suggetions? Time to go over the board, and look for
cold joints (again?). What is the order of the things that the monitor
does? i.e. If the LEDS come on, how much has sucessfully executed?
On the software front, now that MACH 3.0 for the 386 has been
freed and released, does anyone out there with relevant experience have
any idea how much effort porting it to our baby would be? I assume that
this is what project GNU will use for their kernel?

Almost congratulations!

I assume porting a complete Mach-based ux-compatible system would take
about 1600 manhours (well, that's what it has taken our group of 5
students to do it). With a complete ux-compatible system I mean the
Mach 3.0 microkernel + ux-server + emulator + libraries + user
programs (emacs, games, ifconfig, etc.) + cross development tools to
compile the stuff.
We now have a fairly working system, although it is still somewhat
unreliable and contains bugs. We are now in the process of upgrading
to the most recent version from CMU. (Still some work to do).
The microkernel will be made freely available. The ux-stuff, however,
still requires a Mach 2.5 source license -- nothing we can do about
(but your employer might :-). The microkernel without the server(s)
isn't very useful, so those of us who do not have a u*x-source license
need to wait for the GNU-multiserver OS (I don't know if the CMU
multiserver system will be free).
Here is a short :-) typescript that demonstrates a session with the
pc532 used by our Mach-532 group. UFO.HUT.FI is not yet connected to
the internet because of the lack of an ethernet card (j...@hut.fi is
working on one). SLIP works somehow but not well enough for real use.

Here are two sample session logs from the pc532.

Yeah!
Me too! I get LED's, pulses on the ICU..., but no DUART activity. I
checked around and the DUART pin on the IODEC never gets blipped. It
looks like the CPU gets lost after it sets the LED's--the DRAM seems
to get selected, but it shouldn't be (right?). Basically, HELP! I
don't have an o'scope yet, so probing around with my trusty Radio
Shack logic probe is pretty much all I can do for now--until I
drag the box up to the campus electronics labs.
Anyways, I went a got a couple of hex displays and hooked them up to
the LED outputs. Turns out that they fit perfectly in the "speed indicator"
holes that are in most tower and mini tower cases. Now I can watch the
LED lines on the outside of the computer (ooohhh aaahh!).
Oh, I've got 4 1meg simms in the thing without the PARITY pal in place.
I've followed the two major debugging postings I found in this group,
but I think that my board gets along farther than the postings go.
Hmm...
