I don't know for sure but it will probably print something like "XROM
xx,yy". That's what some of the other HPs do. xx will be an id number
assigned to that ROM and yy will be the number of the routine in the ROM.
XROM of …
[View More]courxe means eXternal ROM. XROM xx,yy is how HP usually encodes
the call in memory. If the ROM is present then the routine name will be
printed (or executed in the run mode) otherwise it prints the XROM message
(or halts with an error and displays the XROM numbers in run mode).
I have plenty of 9845 ROMs, I can probably loan you what you need.

I actually …
[View More]came up with an HP transceiver that proves my own point
invalid. It's about the size of a zippo cigarette lighter, but a little
thicker. It's a model# 28685B Ethertwist transceiver and it has dip
switches to enable SQE, Link and Loopback test as well as use of a long
cable. It also has 6 status LEDS near the 10base-T connector. I do have a
small 5-port hub that isn't much larger than some of the AAUI transceivers I
have though.

If anyone has a programmer's manual for either of these daisywheel
printers, I'd really love to know how to invoke the following functions:
DECFIL (Right Justification)
DECFPP (Positioning)
DECPSPP (Print Specified Printwheel Position)
DECPTS (Printwheel Table Select)
DECSS (Set Space Size)
DECUND (Programmable Underline Character)
I don't need full descriptions, but I would like to know the sequence in
the form:
CSI ? 80 h
or
CSI Ps ; Ps " z
I have a database that is supposed to cover …
[View More]every ANSI-compliant
sequence for DEC terminals and printers, but it has some gaps!
Cheers,

I just picked up a complete Sparc 10 system and I am having some video
problems. When the system boots, the video is all ripped and looks like
it wants to be in two columns. It seems to be in the wrong video mode.
It does the same thing with both the mono monitor and color monitor I
have for it. Popped the cover and it has a SUN GX video option board
installed.
Any idea's?
Thanks,
Brian.

78 ohms. The standard also specifies maximum length of 50m for the thick
AUI cable, but "office grade" cables have higher losses and are typically
only rated for a quarter of that.

The MegaST uses an RJ12 for its separate keyboard.

Well, that last "ghetto blaster" spam was interesting in the fact that the
sender made no attempt at all to hide their identity, or to relay through
open third-party servers. Because of this, I believe it may just have been
sheer ignorance on the part of bitways that turned them to the Dark Side of
the 'Net.
I've fired off a LART to mediascape.de, which appears to be the upstream
provider for the company that did the deed. I will know shortly if this is
true.
Maybe we could all chip in and …
[View More]send them a ten-year old boom-box? ;-)

The closest thing to CAP for Windows would be PC-MACLAN from Miramar
systems (www.miramarsys.com). There is also, of course, Thursby's
Dave which whould give you Windows networking on the Mac.
If we're talking just printing, then you might want to look for one
of the old 'lpd' packages for the mac, though I'm not sure how the
Windows boxes would fit in.
Personally, I'd consider moving the LaserJet to a Linux box running
netatalk (like CAP, but nicer) and possibly also installing a
LocalTalk board. As an alternative to the LocalTalk card, use a
second system (LC III or IIsi) with a minimal system running Apple's
LocalTalk Bridge.
