The most known BridgeBoard is ofcourse the A2088XT. It was in my humble opinion a bit late when Commodore came to the market with it. I remember my dad had 80386 machines in his office and I was hesitating what to do. Going to follow the Commodore Amiga grow path or towards PCs and it starting LAN capabilities. Getting a 8088 in the time 286 and 386 were available was for me the reason I never got a 8088 PC BridgeBoard and later one didn’t buy an Amiga 3000 or 4000 but went straight to a IBM PC clone with a 80386. Did they have a 386 for a reasonable price at that moment maybe I was using my Amiga longer.
The A2386SX BridgeBoard has support for 16 bit ISA slots. This is making it more interesting than the 8-bit 8088 version. This BridgeBoard is currently in my Amiga 2000.
It is very difficult to find 8 bit networkcards. 16 bit networkcards are easier to find. With Etherbridge you can use your PC Networkcard on your Amiga in AmigaOS/WorkBench.
At last I could get an A2386SX. Stock CPU and speed are 386SX @ 25mhz. Thanks to Tristan who repaired the floppy diskdrive controller and changed the Intel 80386SX25 into a Cyrix 486DLC50 which performs like a 80486DX-33.
The advantages of the A2386SX over the A2286 are the CPU speed and the onboard RAM of which I have 8 MB installed (fully occupied).
The Cyrix 486 @ 50 mhz is 3.7x faster than the 386SX @ 25 mhz (not bad).
Soon photo and details come after it arrives 🙂
UPDATE: It arrived !
Time for some benchmarking

I used a CF Card with JanusTools as my MS-DOS partition via hardfile. Check out my settings on JanusTools DOSType. Currently using a dedicated CF Card of 4 GB see info in add-on section below.
