Hopefully, someone in NETLAND has one and can answer. 1. Which slots (in a 2000) are taken up by the installation of the bridge- board? An amiga slot? An AT slot? One of each? Because of the daughterboard on the AT Bridgeboard the installation takes up 2 slots. Whether they include the other AT slot or the next Amiga slot depends on which where they are installed. 2. If I wanted to add external monitor (in conjunction with the bridgeboard) for VGA capabilities, could I just pop in an IBM VGA card and add a VGA monitor? Would this work? Yes, you can install a VGA card and it will work. I recommend getting one of the cards listed in the 2286 manual since they have been tested by CBM. You also have to set up PCPrefs to turn off the normal Amiga output to the windows. A lot of confusion occurs when people first do this because they can see the IBM side but can't type in it. In order to enter the IBM side you must have one of the console windows open and active on the Amiga side. I usually just activate the PCMono window for this. 3. What type of IBM cards will work well with the bridgeboard? What about something like the ADLIB or SOUNDBLASTER music cards? Most cards should work fine with the Bridgeboards. The ones that don't tend to be ones that access COM2 which I believe CBM has taken the interupts for their own use. many thanks - please reply in EMAIL Larry Cline lcline@sequent.sequent.com --- Received: from uunet.uu.net by handel; Mon, 12 Nov 90 22:19:23 mst Return-Path: Received: from smosjc.UUCP by uunet.uu.net (5.61/1.14) with UUCP id AA21266; Tue, 13 Nov 90 00:19:36 -0500 Received: by smosjc.smos.COM (5.59/LAI-3.1) id AA20808; Mon, 12 Nov 90 21:02:25 PST Date: Mon, 12 Nov 90 21:02:25 PST From: smosjc!brett@uunet.UU.NET (Brett Coon) Message-Id: <9011130502.AA20808@smosjc.smos.COM> To: uunet!handel.CS.ColoState.Edu!millerje@uunet.UU.NET Subject: AT Bridgeboards The AT Bridgeboard takes up both an Amiga slot and a PC slot. As a result, it has to be placed in one of the two positions where these slots overlap. Yes, you can just drop in a graphics card (VGA or other) and connect it to a monitor and it will work. The Bridgeboard manual lists some cards that are guaranteed to work, but in general anything that works on a real AT will work on an AT Bridgeboard. The only thing to keep in mind is that Amigas are only shipped with 2 AT slots; the other two slots are 8-bit XT slots. Since the Bridgeboard itself takes up one slot, that leaves room for 1 AT add-in card. If you want, the Amiga motherboard is designed to allow you to solder in 2 additional connectors to convert the XT slots to AT slots, but that takes a little extra work. According to the Bridgeboard manual, most PC cards will work fine. About the only source of problems is the interrupts used by the PC-Amiga connection. Apparently some accellerator cards use the same interrupts and hence won't work with Bridgeboards. Other than this, I've never heard of any problems. The only add-in card I've used is a serial port card, and I had no problems. Now, if I've convinced you that the AT Bridgeboard is awesome, I just happen to be selling mine. Seriously. Everything I've said above is true, I just have decided that I have more use for a laptop than a Bridgeboard, so I'm selling mine (or trading for a laptop). If you're interested, I'm asking $900 or best offer, and I'll even throw in that serial card (I forgot to mention it in my post to comp.sys.amiga). -brett |Brett Coon | uunet!smosjc!brett | |S-MOS Systems, Inc. | "You like 'em, anchovies?" | |San Jose, CA | -Runaway Train | --- Received: from holst.cs.colostate.edu by handel; Mon, 12 Nov 90 10:47:24 mst Return-Path: Received: from [192.36.125.2] by holst.cs.colostate.edu (5.58/SMI-DDN) id AA03591; Mon, 12 Nov 90 10:45:28 MST Received: by sunic.sunet.se (5.61+IDA/KTH/LTH/1.162) id AAsunic03386; Mon, 12 Nov 90 18:47:42 +0100 Received: from eos.ericsson.se by ericom.ericsson.se (4.1/SMI-4.0-ERICOM1.4 ) id AA16558; Mon, 12 Nov 90 18:19:09 +0100 Received: from eos5c08.ericsson.se by eos.ericsson.se (4.0/SMI-4.0.2) id AA23327; Mon, 12 Nov 90 18:19:06 +0100 Received: by eos5c08.ericsson.se (4.0/SMI-4.0.2) id AA08786; Mon, 12 Nov 90 18:19:00 +0100 Date: Mon, 12 Nov 90 18:19:00 +0100 Message-Id: <9011121719.AA08786@eos5c08.ericsson.se> To: millerje@holst.CS.ColoState.Edu From: Tommy.Petersson@eos.ericsson.se Subject: Re: bridgeboard Newsgroups: comp.sys.amiga In-Reply-To: <11090@ccncsu.ColoState.EDU> Organization: Ericsson Telecom AB Cc: Tommy.Petersson@eos.ericsson.se In article <11090@ccncsu.ColoState.EDU> you write: >Here are some questions that, it seems, nobody around here can answer about >the AT bridgeboard.

The bridgeboard is the bridge between the Amiga part and the PC part, so it installs in one of each. You can choose one of two places, depending on how many Amiga/PC slots You need. The two PC slots on the far left (seen from front of machine) can easily be made into At slots (soldering of sockets). > >2.

You can then run in parallell on the two monitors. Just make the PC window that always (?) shows up on the Amiga side as small as possible to make it slow down as little as possible. One MultiScan monitor and switching of the monitor cable between the VGA card and the Amiga is also possible (9-23 pin adaptor necessary). >3.
