Terminal (servers), cables (was Re: [HECnet] RHESUS is (finally) up again)

[Steve Davidson]

The RJ45 to MMJ adapter is known as a H8584-AA (in my case REV A).   I
use them on my DEChub-90TL's.   They work GREAT!   They can be hard to
find these days and also costly, but well worth it.   Start on Ebay.

how much faster I can get the VT520 talking to the 90M.

The 90M I have must have flash in it of some sort, as it boots if MISER
is 
down, although it takes about 2 days ... ;)   I have a line on a 700 with

flash so I'm hoping I can "upgrade".

You shouldn't have a problem hooking that 520 up to your 90M, because
I'm 
typing this to you on my VT525 connected to the 90M, connected via LAT
to 
MISER and ssh'ed into my main Linux machine.   (whew!).     This way I
don't 
have to fire any of my workstations up in the morning before I get 
underway for the day just to check the mail (simplicity, eleganace and
all 
that).     I also have a VT220 I'd like to hook up in the living room 
someday ... :)   I figure 50 feet at 9600 would work just fine.

Your issue (like mine was) may be cables - either you'll have to use a 
RJ45 to MMJ cable wired appropriately, or get some of those RJ45->mmj 
things that plug into the terminal server.   I have a wiring guide for 
DECServers if you need it and can place it on a HECNet accessible drive
- 
just let me know.

I have an abomination of a connector/cable hooking the 90M to MISER's 
console, some DB25-9pin job connected to a null modem adapter connected
to 
a db25-mmj with then some silver satin running to the decserver ... I'd 
like to clean that up as MISER is in possession of my only null modem 
adapter!! :)

Cheers,

Fred

polite but derogatory manner to imply that the future direction they
prefer is not that which they view as the current direction.
