From what I

to be set manually, right? How to do this, I'm not sure.
Wasn't this system preconfigured when you got it?
That would say to me that it was likely already 90-99%
ready.
At any rate it will be useful to record the card and slot
location info for your system for later.
Well, yes and no. The machine had a CPU card, serial card and RAM in
it, but nothing else. And I didn't know how the serial card was
configured. Now I have figured out how the serial card works, but I am
trying to get the machine to boot off tape. I haven't even begun to
think about hooking up the hard drive yet.
I don't know for sure that I have the tape
drive connected
right though.
The cables are labelled P1 and P2. Locate the pin 1 point
on the source, cable and destination and line 'em all up,
once for each cable.
I'm assuming that P1 and P2 would go to J1 and J2 respectively, right?
That's what I don't know. I've got pin 1's matched up, but I don't
know
for sure if the tape controller and tape drive have their connectors
numbered the same way. With my luck, they won't be...
Here is the
boot program I'm trying to use:
Might be useful but more likely with this system is that it
would boot by loading just one address first, just my hunch
for now.
Yeah, you're probably right. I'll have to look at the hardware some
more and post more information.
