PDP 11/73 is ALIVE!

Last week I got the system unit and the tape drive mounted in the rack, and yesterday, I managed to mount the Fujitsu Eagle. Now I'm trying to figure out how to hook it all up... I have been tinkering with it this morning, and finally, about a half hour ago, I was able to see some activity. I found the information on the serial board in a handbook, set the terminal for the proper baud rate, etc, and connected it to channel 3 of the card. Powering it up gives me the @ prompt. So far, the only things in the machine are the CPU, the serial card, a 1mb memory board, and an Emulex tape controller. Now that I have gotten it to do something, I'm totally lost. I've never worked on a machine like this before. I don't even know how to type in the boot program. I have a tape boot program here, on a piece of paper, but I don't know how to type in the values. I've tried all sorts of commands, all of which yield a ?. Typing P seems to step the processor through something, as it prints 000002, and then typing P again increments that value. G prints 177777, and the LED on the tape controller lights briefly. Same thing if I toggle the boot switch. I tried loading a tape into the drive and putting it online, but I get no drive activity when I toggle the boot switch. So, can anyone offer hints or suggestions as to what I should do next? I'm lost... Thanks! Ian Primus ian_primus(a)yahoo.com
