I scanned this schematic from my Heathkit Clock manual
hopefully it may help.
My Heathkit clock died and I am in need of a MK5017,
do you know where I can get any?
Thanks,
Walter.

This may not be a processor dependent issue.

My facit N4000 reader/punch has developed a problem.
Would anyone have a service manual for this unit? I have the operators guide
but no service manual.
When powering up the unit, about 20% of the time it comes on with "Err" in
the display. If I turn it on and off a few times, it comes up correctly with
"Off" in the display. Also, the test tape created in diag test #4 mostly,
but not always, passes it's read in diag test#5.
Can anyone help with a loan of the service manual or perhaps some advice?

Ok, I am replacing the HP terminal with either a Macintosh SE or an
Apple IIc+...
Environment = Linux running simh pdp11 running RSTS/E V7.0 (with
telnet from all my other machines)
Has to sit in a 2" x 2" square area on my desk, although I think all
three choices overflow the
intended area.
Please weigh in on the following three scenarios:
Door #1 - Macintosh SE
- Have an appletalk laser printer for this machine
- perhaps smaller footprint.
Door #2 - AppleIIc+
- Imagewriter instead of a laser printer if any printer at all.
- Coolness factor (8 on a scale of 1 to 10) 10 would be a real DEC
terminal..
- No Terminal software at hand.. (would beg someone to send me a
diskette)
Door #3 - HP Terminal
- already and still hooked up, and works ok... but.
- it's not *also* a computer that I want to get back on display.
Your comments requested.

Another possibility would be a Sharp Zaurus. They run Linux. I have
an SL-5600, which I use with Kermit (serial port) and telnet (Ethernet
or wireless) for talking to network switches, but it has a good browser
and you can get a PDF viewer for it. I've not used the PDF viewer so I
don't know how good it is.

I've got a few as well. Interesting devices.

Ok, thanks, so I'm back at square one.
I think maybe I'll buy an old tablet PC on ebay. I can probably pick up
an early pentium unit for $100 or so, and speed isn't important for
reading a PDF.
thanks!

I finally checked out the HP 1000. It seems to work. I checked and the
CPU section has a DCPC card, Memory Protect Bd, Mem Bd, four 256KW memory
cards and a 2102E Memory Controller. The IO side is full of cards. Here's
the list: I/O Buffer, I/O Buffer, 12966A BACI Bd, 13183 7970 Mag Tape 2,
13183 7970 Mag Tape 1, 26099A Line Printer, 26099A Line Printer, Bus I/O,
12966A BACI Bd, 12966A BACI Bd, 13037 Intface, 12821A Disk Intface, Time
Base Gen, FEM. It seems to be quite a nice machine.

I went to one of my favorite scrap sources today but I was just there a
few days ago so I didn't expect to find anything. But I was wrong! I found
a NICE F series HP 1000 along with the Floating Point Unit. I haven't
looked at it closely yet but all the card slots are full and it's in very
good condition. It was mounted in a short (desk height) HP cabinet marked
"HP 1000 System" along the top. Unfortunately I had to leave the cabinet,
it was just too big and heavy fit in the vehicle that I was in. I'll go
through the computer later and give a full list of all the stuff in it.

I know this is going off topic, but how well does it work as an eBook
reader?
I'm looking for something fairly portable for ebooks. I have stacks of
books and manuals in either HTML, Text, CHM (crappy HTML), or PDF format.
And I haven't read them all yet because currently my computer is the best
place to read them, which conflicts with me getting most of my reading
done on the crapper.
So I either need some portable unit to start reading ebooks, or I have to
install a computer in my bathroom... humm... no for the sake of my
marriage, I'd better just go with a portable unit.
I've used my Palm for the text files, but the formatted HTML, and CHM
files don't work so well on that small of a screen. And my Palm can't
handle PDF. Is the Cybiko any better of a screen then a Palm? Can it do
anything beyond plain text?
