Regarding the serial number, IIRC it is stored in
an EEPROM in the later
machines but in the early ones it is in the BootROM. At least that's what I
seem to recall. I've never hacked the hardware on these machines so I'm
just going on what I've heard or read.
I don't think so. I think the boot ROM -- the ROMs containing the
executable code -- are the same on all machines of a particular type.
There is no serial number stored in them. The service manual implies
there's a separate ID ROM, a little, looks to be bipolar, thing.
I can't easily get to my 9836, and anyway I don't know what CPU board I
have (the first 2 versions of the CPU/RA< board don't have the ID PROM at
all). When I dig it out I'll let you know what I find.
I guess you don't have the manuals for this.
AFIK I have the full set of
manuals for BASIC 5.1 along with a bunch of other useful related HP manuals
No specific manuals for this disk set, no. I have HP BASIC documentation
for other systems, but that doesn't cover configuration.
I have the 9826/9836 service manual from Jon Johnston (the chap who runs
hpmuseum.net). It's a boardswapper guide, of course, but with some useful
information in it (read : stuff that would take more than 10 seconds to
work out from looking at the mahcine). It's often the way with HP service
manuals, much of it is obvious, but there's often something that really
helps with understanding the machine if you read it with a hackish eye.
such as the HP 9826/9836 and HP 9000/300 Series
Computer Installation
manuals, various peripheral configuration manuals, BASIC 2.1 and 3.0
manuals, HPL manual, Pascal manuals, Self-Study Guide to Instrument
Interfacing using HP Basic, FSD Customer Engineering Manual and more. This
I am not sure I specificially need any of that at the moment...
stuff needs to be made available to the everyone. Al
has asked about
borrowing the stuff and scanning it and I've told him that he can but we
But putting it on bitsacers would be a very Good Thing!
