The only thing I remember the printer port being used for was some cheap-assed eprom burner, and a weird 9000Hz sound sampler. Usually manufacturers had the sense to use the 1 Mhz bus. I really wouldn't go to much effort to bring it off-board in your ACW. I doubt you'll ever get a chance to use it. By the way I'm borrowing Joe Rigdon's US Beeb so I can recover the code on my BBC 5.25" floppies, which is where the sideways RAM loading code you were looking for is stored. Unfortunately I did't have any copies of it on the Archie disks (which had been easier to restore). My experiments with fitting a 5.25 drive to a PC and reading the files that way were a complete disaster. The first attempt scored gashes in some floppies until I noticed, then after buying an identical (but working) drive on eBay to replace the bad one, I found that the code I had to read the disks just plain did not work reliably. I tried several PCs, including old ones, knowing the problems with incompatible disk chips. I was also unable to get the disks working under any Beeb emulators. (Unlike with the Archie emulators which worked a treat with 3.5 disks!) Once I get the US Beeb and can read the disks native, does anyone have any good suggestions on how to read and transfer disk images to Unix over a serial line? Remembering that I'll have to bootstrap any process by typing the code in to the Beeb. I guess I should start wiring up a Beeb<->PC serial line right now! G
