2339RE: [BPQ32] Tiny BPQ Switch
- Oct 10, 2009
MessageI'd looked into building a PC-104 based switch, but never quite got round to it. Your's looks pretty neat.There is also a version of DOS BPQ for the Kantronics Data Engine, Although these have been out of production fr a while they occasionally appear second hand, and there are quite a few still runnnig as hilltop BPQ Nodes.73,John-----Original Message-----

Subject: [BPQ32] Tiny BPQ SwitchHere's a four port BPQ switch utilizing a PC-104 form industrial computer, a 33 Mhz 486 that in a previous life operated a touchscreen data pad. It needed a new 3v motherboard battery and I had to cobble together the I/O connections.It runs on 5v DC, has a flash drive ( no moving or rotating parts ) a built-in watchdog setup and is hardened to take industrial conditions. ( Dust, vibration, temperature etc. )It fits in an old case for an MFJ 1270c with room to spare.I use ROMDOS, a special DOS for PC-104 computers, and it works flawlessly with DOS BPQ. There is also a copy of FBB BBS i9stalled, so I can connect on the air and do software updates, reboots, etc. using FBBDOS. I do not use it as a BBS but in a pinch, I could.So - if anybody asks if BPQ can be utilized in remote mountaintop node sites, you can say "You bet!"Note that I also have a four port FlexNet digi installed in the Flash drive, and can switch between one system and the other by altering the autoe*ec.bat file.I think this probably gets the prize for the tiniest BPQ switch - and it is also one of the toughest.The newer industrial PC's could run BPQ32, as they generally operate with Windows. - I got this older PC-104 for 29 bucks.73 DE Charles, N5PVLPrefer to use radio for your amateur radio communications? - Stop by at HamRadioNet.
