I recently acquired what I believe to be a Heathkit H89. It was assembled a long time ago by my friend's father, contains a single disk drive and a monochrome terminal. My ultimate goal would be to get this thing running CPM and a C compiler, but first I need to figure out if it's working. I've yet to determine if it has a hard or soft-sectored disk controller, but I have some general questions since I don't have any documentation. First, where can I get some documentation? ; ) Second, when I turn the machine on, all I get is a blinking cursor. If I depress the "offline" key, I can type characters on the terminal accompanied by a short beep; if the "offline" key is not depressed, I get long beeps and nothing on the display. What "should" it do when I turn it on with no disk in the drive? I'll be happy to provide more info as I dig it up, but any introductory details on this system or references to websites, etc. would be greatly appreciated. Jason J.
