About 5 min?

There is -11.57 to -12V signal on pin 2(it keeps changing). But my 
windows hyperterminal didn't get anything meaningful. Maybe 
hyperterminal configuration is wrong?

Ok. I'll start from scratch again. Please tell me if what I'm thinking 
is right or wrong.

1. Flash ROMs are broken. So I need booting floppies to bring them back. 
They will be prepared from DEC's CD - 164lx.exe(v5.8) and gtsrm.rom(for 
up1100, I forgot the ftp site) using mkboot.exe from digital site to 
make boot floppies. Their size is about 1.4M

2. Set jumpers of Alpha machines for fail safe boot as manual describes 
(All manuals from different vendors - Samsung, Alpha Processor Inc., 
DEC, Compaq) suggest same jumper setting. This will cause booting from 
floppy.

3. Set serial line from COM1 of Alpha machine to other machine(currently 
only available machine is windows) with vt100, 9600, no parity, 8bit, no 
control flow.
(question: should I use SROM port - e.g. mmj interface -  instead of COM1?)

4. Start an alpha machine.

5. Then I can expect spinning of floppy drive (with or without  serial 
line connection, I guess).

That's about it without any try yet. Am I missing anything important here?
