#BridgeBoard info needed
2 messages in this thread
I am looking for some information and I hope someone here can tell me
where to find it. First I would like to find out what subroutines are
available in the Janus library and how to use them. I would like to try
writing some programs in C to transfer data between the Bridgeboard and the
Amiga, but I can't find any references in the manuals that came with the BB
on how to use the library or even the name of a Janus library reference
book or manual. Has anyone out there heard of such a manual?
Second I have a problem with a IBM compatable laser printer I bought (it
was being closed at a discount price so I can't return it). The problem is
not with the controller card however. The program that downloads the
Postscript interpreter to the controller card uses a hardware timer on the
IBM to generate delays in waiting for responses from the card.
Unfortunately the AT Bridgeboard timers chips must not be at the same I/O
ports or use different stop/start/clear control bytes because the download
program hangs up waiting for the chip to time out. Does anyone know of any
manuals that tells how the Bridgeboard chips work and where they are
located so I can try to make a neat patch for this program (I have gotten
the program to run but it produces false error messages I would love to
eliminate).
Thanks to any/everyone for any and all help.

The A500/A2000 Technical Reference Manual is probably what your looking
for to get information on the Brigdeboard Stuff. It contains the Interface
Memory Maps, Register Descriptions, Block Diagram (XT Only), Janus Library
public routine descriptions, BIOS entry points and all of the Include file
listings needed. Unfortunately, it doesn't go into any great detail on how
to use them (actually no detail at all). You have to figure that out
yourself.
You have to order it direct from C=. There's a file somewhere in the
Libs, I believe its called CBMDOC.TXT which gives a list of all the
technical documentation that's available from C= (as of 3/88 anyways).
I just bought the manual last month for the same reasons, to see if I
can figure out how to write my own software to have both sides communicate
with each other. The problem is, i'm still fairly new to programming on
the Amy side. If you get anywhere on it, i'd love to hear about it.
It costs $40.00 to get if you send a letter to the following address:

Read the CBMDOC.TXT file for more information. Hope this helps out.
