Our membership is now near 150 with the users about equal in size to the C- 64/128 users. Most of the nominees for the club's Board are from the Amiga users.

The Amiga meetings are moving to meet needs expressed at the two members from the Commodore section are nominated last two sessions. This involves breaking the meeting into for the hotly contested Member-at-Large position, so if the several small groups to cover various topics such as novice Commodore section is going to have Board representation, training, Command Line Interface usage, the Commodore members really have to get out and vote telecommunications, AREXX command language, and on the 20th. others. Video and graphics remain as the Amiga's strong . I would like to take this time to thank all the points, so demonstrations and presentations will dazzle Board members, volunteers, and any members who put there yet. A Disk-of-the-Month will still be sold. What forth effort toward keeping the club going: changes should the C-64/128 group make?

BridgeBoard Technology Moves into the Late 80's By Steve Jess

Ever notice that Commodore always seems to be one generation behind in bringing out BridgeBoards (MS-DOS Compatible cards) for the Amiga? When MS-DOS users could buy 16-bit AT computers. Amiga users wanting compatibility were limited to the 8-bit XT BridgeBoard. As 32-bit 386 machines were gaining momentum. Commodore produced (tah-DAHI) an AT-compatible BridgeBoard. Now that 486s are the rage. Commodore is out with a 386SX BridgeBoard. Now, don't run down to your dealer and try to buy one. Run down to your dealer and buy an AT Bridgeboard. because until the backlog of AT boards is reduced, Commodore apparently won't officially introduce the 386SX unit in America. For the time being. it's only on sale in Europe. (Incidentally. for those who don·t know. the 386SX is an 32-bit processor, just like the regular 386 chip. However. the 'SX is connected to the rest of the world through a 16-bit bus. so it can use AT-style 16-bit hardware. instead of more expensive 32-bit expansion devices. That keeps costs down. but it also results in a 20 percent speed penalty. A 20 MhZ 386SX runs roughly as fast as a 16 MhZ 386, in other words. The SX is ideally suited to the and 3000 Bridge slots, which are AT-style 16-bit slots.) An English CompuServe user listed the following features for the new A2386 Bridgeboard: "Processor: 80386SX Clock Speed: 16 or 20 MHZ Co-Processor: Optional 80387SX Memory: Expandable to 8mb on board. (256kb x 4 or 1M x 4 page mode ZIP's) Floppy Disks: Supports up to 2 drives from the following: 1 PC only external drive (3.5 or 5.25) 1 or 2 PC only internal drives of the same type 3.5 720kb/1.44mb PC 3.5880kbAmiga 3.5 880kb I 1.76 dual speed Amiga 5.25 high density PC 5.25 low density PC 1 shared 3.5 Amiga drive (DFO: or DF1:) Card Type: Uses the Amiga 100 pin PC I AT busses. Occupies one of the two combination Bridgeboard slots.

Video display: IBM-PCIAT MDA mono 80 x 25 IBM-PC I AT CGA colour 80 x 25 IBM-PCI AT CGA colour graphics 640x200 x 2 and 320 x 200 x 4 "Comes complete with MS-DOS 5.0. 3 user manuals. 3 different ribbon cables for different floppy setups, 4 diskettes, new style install program which will automatically setup a C: drive virtual on your Amiga hard disk, new WB2.0 style PCPrefs program. PC setup and more. Includes ability to share DFO: or DF1: as Amiga or PC drives using a program called flipper which runs in background and detects DOS type of floppy and acts accordingly. "I have just got the 20mhz board with 8mb of ram and am up and running with minimal fuss. Will be installing windows 3.1 any moment." Editor's note: You'll notice even the new 386SX Bridgeboard lacks the capability to generate VGA video on the Amiga screen. You have to accept fuzzy old CGA. or buy a separate VGA card. My guess is Commodore can't figure out a way to squeeze all the data needed for VGA through the relatively small 128k of "dual-port" memory that the Bridge shares with the Amiga. Solution: if you've gotta have VGA, buy a cheap VGA card (they're as low as $39) and a switch for your monitor.
