'rescue' updates



#10

So.... I've got one nearly trashed 9114B that i picke dup for $20 which now seems to function fine.

I rebuilt the battery pack (though my batteyr is in a pod externally, it still works great.) Read write test on 41CX and 75D..... gorgeous!

Except, the test light won't go out. i can't find any functionality not working, but...... in theory this means *error*

Now I need to buy more HPIL cables so I can connect the printe rin the loop.

I should be ready in the next day or two to do some real testing with the 86B and associated disk drives. I'll test the printer once I get a ROM drawer and figure out how to make a printer ROM.

I found an HPIB interface in SBUS format for my Sun workstations, but hav eno clue how to make it go.

and, finally, I found a really cheap laserjet III and have made it work with my 200LX for serial printing :)

I'm still playing with materials to replace the flexible conductor tapes in the spice machines, I just don't *like* using wire.

You don't need a "printer ROM" to use the printer. You just
type

PRINTER IS 705

This assumes that the HP-IB adapter is at the default position (7) and the printer has HP-IB address 5.

Then if you sy

PRINT "HI THERE"

or

PLIST (to print the current program)

The printer should come to life

Also if you want to log everything that appears on the screen (in character, not graphics mode), you just type

DISPLAY IS 705

And to return "printing" to the screen only (ie. stop echoing everything to the printer), just type:

DISPLAY IS CRT

or IIRC..

DISPLAY IS 701

My memory is being faulty this morning... (I don't have my HP 85 manual handy :-)

Vassilis Prevelakis is correct in his post.

I think I'm confusing "PRINTER IS" and "DISPLAY IS" commands.

Next time I'll wait until I am sure of my answer before I post it ;-)

What is the printer/plotter rom for specifically, then?

color choices and printer graphics?

thanks!

To quote from http://www.series80.org/accessories.html

00087-15002 Plotter ROM:
Allows data to be transferred from the HP-86/87 to an HP plotter. Also provides single commands to dump CRT graphics and alpha screens to any HP
dot matrix printer. (Print and graphics commands for transferring data to an HP printer are included in each HP-86/87). Consumes 1392 bytes of
available user memory.


The HP-85 has a built-in printer which can produce screen dumps, but does not have software to drive external printers, so HP produced the Printer/Plotter ROM that allowed the HP-85 to drive external printers and plotters. The 86 and 87 do not have a built-in printer, so HP included the GDUMP program (see below) in the demo disk supplied with each 86 and 87 system. HP also supplied the Plotter ROM that provided similar functionality as the 85 Printer/Plotter ROM.

You can download the GDUMP program from http://www.series80.org/Programs/index.html
which allows you to dump the graphics display to any of several graphics printers.

BTW I made a mistake in my ealier post, the Series 80 do not have a DISPLAY IS command, rather a CRT IS. To send output to an HP-IB printer (address 5), you use

CRT IS 705

and to turn it off, you use

CRT IS 1

okay, now armed wiht a magnavoz series 80 monitor and a 9121D dual floppy drive, I'm ready to go....

or maybe not

1: MASS STORAGE IS xxx doesn't work with anyhting I cna figure out (the test switch is up (normal) and the address switches are 1=down 2=up 4=up) on the drive.

the built in HPIB (it *is* built in HPIB on a 86B machine, I am assured. And it's labelled) doesn't seem to have a switcc system *shrug*

so, mass storage is 701 doesn't work, neither does 706. this is also true for prefixes 0,2,3,4,5,6. ( haven't tried 1 yet, guess I will soon)

I get error 88, BAD STATEMENT no matter what I do with mass storage.


2: the monitor is fine, but I'm having the same problem I had using the PC and TV composite inputs. the top 2 " pixel lines" of the top line of the 86 display are out of the range of all composite video outputs I've hooked up. Not world shattering, but weird. makes a capital A look like a shortened H.

any ideas?

I hope you are using

MASS STORAGE IS ":D701"

and not

MASS STORAGE IS 701

which doesn't work.

Have a look at page 16 of the Mass Storage ROM Manual and don't take liberties with the spelling :-)

I type quite well when I'm on a decent keyboard, really :)

I see the syntax now, looking through that.

MASS STORAGE IS ":D701" just... hangs.

Granted, this is a 9121 and I dont' appear to have any floppies that will work in it (it takes some other kind of 3.5 inch disk? one that I don't have, apparently)

But I have another HPIB floppy appearing soon, and a second HPIB interface which I cna set to a different address and keep testing things.

not sure about the display, there doesn't seem to be any obvious way to tune the output...

back to printing manuals, thanks....
