      I was wondering about the alignment issue.

      I ran a BBS on an old TRS80 with 4 floppies and was sending drives off over alignment issues every few months and that was from normal read/write accesses. Luckily, my local Radio Shack was cool and looking for support from the BBS community and ate the cost.

      Us TRS80 users had the tape motor relay as our audio toy. It was a simple coil relay that would make a very audible click when engaged or released. Though there was code to control the speed of access in BASIC, there were no limitations on what you could do with it in ASM. Apparently, the limitation was put in place to keep from destroying tape drives and the relay.

      I remember producing some really disturbing sounds, but ended up rigging the tape relay up to the power cable to my modem. With a small bit of code, a few wires, and raped cassette drive cable, it was relatively easy to turn the old RS 300 baud modems into auto-answer. Basically, splice the power cable to the modem, cut the cassette cable's drive motor and connect the two. Then splice the phone cable and connect the two live wires to the audio-in cable, then make a loop in ASM or BASIC that watches for a particular memory address value to jump from 7-10 to 250-255 for a few moments, then issue a MOTOR ON command and close the loop to power the modem who's switch is already flipped to ANS mode. Of course, this had limitations. I had to spend a lot of time tooling code for the BBS that would reduce the chances of a hung, dead connection (if the user hung up without logging out) as there was no actual carrier detection. My final solution was a TSR that would MOTOR OFF and reload the answer script if there was no activity for 2 minutes.

      That's another example as to why I always considered Commodites to be similar to what script kiddies of the mid-80's would have been, compared to the more traditional TRS80 hackers. The Commodites downloaded someone else's crap and ran it while us TRS80 ppl got out the soldering iron on a regular basis or learned ASM so all 64k of resources would be usable. :-)
