***Memory***

ref http://www.vigyan.com/~blbates/sgi/hardware_notes/memory.html

The Indigo2's have 3 banks of 4 SIMMs'. All the R4x00 CPU's can have a
maximum of 128MB/bank (4*32MB SIMM's) or 384MB total. The R8000 &
R10000 CPU machines can have a maximum of 256MB/bank (4*64MB SIMM's)
or 768MB. Some SGI engineers have said that one can put a maximum of
two 256MB banks in these machines, because of cooling requirements.
This would limit an Indigo2 to 640MB. I've two reports that 768MB
works fine in an Indigo2 R10000 (3*256MB).

The following URL shows where people have installed and used 1GB of
memory in R10000 Indigo2's.

Impact is not supported on Power Indigo 2 systems with R8000! While
Silicon Graphics had planned to support this configuration they did
not release a driver for this. (This information has been obsoleted by
history itself. There are reports of working R8000 Impact systems so
there must be support in IRIX.)

From http://www.futuretech.blinkenlights.nl/pinouts.html

?For teal Indigo2 systems which have an Indigo2Video board and
CosmoCompress installed, there should be a cable that connects the two
boards together, linking the two IndyCam-type ports that are
vertically adjacent. Unfortunately, this cable is often lost, so what
do you do if you find the boards but don't have the cable? The
solution is to utilise two ordinary IndyCams, hacking the cables and
wiring them together - obviously, it would be best to find two
IndyCams that are non-functional but which still have intact cables
and connectors.

An original Cosmo connector cable is very short, just 45cm (approx.
18?) long, and is quite thick, presumably heavily shielded. Thus, I
can't say for sure how good a cable made using two IndyCam cables
would be - it depends on whether all the pins inside the IndyCam
cable's connector are used. What I can say is how a genuine Cosmo
cable is wired up, which is as follows:

Looking face-on at the two IndyCam-type connectors, held the same way
up, the pin connections are a vertical mirror image across the two
plugs. Thus, the top-left pin on one plug connects to the bottom-left
pin of the other plug. Similarly, counting rows from the top and
columns from the left, the pin at row 2 column 7 of one plug connects
to row 3 column 7 of the other plug, while row 1 column 12 connects to
row 4 column 12. The column numbers stay the same, but the row numbers
are mirrored: row 1 connects to row 4, row 2 to row 3, row 3 to 2 and
4 to 1.

I don't know if all the connections are necessary, but that is how an
original Cosmo cable is internally wired.

NOTE: on the Cosmo cable I have, the connector which goes into the
CosmoCompress board's socket has an iconic picture of a video camera
on it. Since the cable is basically just a vertical pin-for-pin
swapover cable, I doubt it matters which end is connected to which
board, but this fact should at least help in identification of the
correct kind of cable. There is also what appears to be a part number
on the cable, namely 018-8217-001.?


LFH60 cable

Cisco crossover cables don't look likely to work.

not all pins are connected normally, so unlikely that all pins are
actually wired either way, the crossover is not a straight mirror
image as required by the Cosmo ? Galileo connection Possiblity for
cable

?ribbon cable connector? = 34-conductor ribbon cable inside machine

Breakout boxes


junior

Green vacume-cleaner-attachment-shaped dongle with 5 analog video
jacks at one end, and an ?analog breakout connector? that plugs into
the board at the other end.

2 RCA analog composite inputs (there is a special mode where you can
use these as a Y/C input)
1 svideo analog (Y/C) input
1 RCA analog composite output
1 svideo analog (Y/C) output


Homebrewed

From http://catbull.com/marcx/sgi/i2v.html

The Parts

Cable from box to the card:
   1 male SUB-D 26
   1 cable with 14 lines

The box itself:

For the INPUT:
   1 MINI-DIN 8 (SVHS)
   2 cinch (composite)
For the OUTPUT
   1 MINI-DIN 8 (SVHS)
   1 cinch (composite)

The IndyCam input is right on the card, where there is also a female SUB-D 26.
This is where the cable from the breakoutbox goes in with a male SUB-D 26.

One has to connect the pins from the box (3 cinch, 2 miniDIN 8) with
the SUB-D 26 via a cable with 14 lines. Note you have to think about
the length of this cable!

The Schematics

I used the following schema and tricks :)

Misc

?One more bit of trivia: On the R8000 and R10000-based Indigo2 models,
you can change the bootup tune! To my knowledge, this is the only SGI
platform on which you can do this. By setting the ?boottune? PROM
variable to a number from 0 to 6, you can choose a particular setting.
0 is ?random setting?, which causes the machine to play a random
selection from the available boot tunes.?
