For those of you that collect gaming systems also, I was this months
Collector's Spotlight person in the VIDEO GAME COLLECTOR #2 issue. Check it
out and excuse the bad picture my wife took of me.
I could have sworn I had a case of blank tape reels for my facit punch.
Can't seem to find them, but I can find a bunch of blank fan-fold tape so
maybe that's what I was thinking of :\
Anyone have some reels of blank paper tape for a facit punch they'd care to
trade/sell for? I'm looking for an initial stock of maybe 8 reels.

Hi there I have the same problem... Looking for the Sony MP-F52W-00D floppy drive. Would like to know if you can give me the phone number to the Sony Company you called. Would much appreciate it. You can contact me at www.fabio_padula@hotmail.com
Hi - does anybody know of any copies of the KA640 Tech Manual online? I
think i've got a blown DSSI picofuse* and i'd like to have a casual flip
through the manual whilst i'm away from the system.
I've searched Manx and poked Google, both turned up nothing.
Cheers guys

This talk of software handbooks reminded me...
I have a "VAX Hardware Handbook 1982-1983". (Copyright 1982.) Covers the
11/730, 11/750 and 11/780 (at least, going off the chapter sections.) It's
in pretty good condition for it's age.
I'm never going to have a use for it, so it's Free to anybody who wants it
- just cover postage to your neck of the woods. (I'm in the UK.)

I would suggest unoiled dark blue. Black has a high carbon content
which is bad for punches.
Paul:
Thanks -- that's exactly what I was looking for. Bitsavers.org has a
copy of that tape on-line.

It was called "Magenta Martini", if that helps. Made a huge splash in
the monochrome world of computers at the time.

(I sent this first to the rescue at sunhelp list, but figure people here
might be of more help with older machines.)
So, I've tried booting my Sun 3/180, and can't get it to work. With the
switch set to "diag" on the back, I get the following output:
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
Boot PROM Selftest
PROM Checksum Test
DVMA Reg Test
Context Reg Test
Segment Map Wr/Rd Test

TOD Clock Interrupt Test
MMU Access Bit Test
MMU Access/Modify Bit Test
MMU Invalid Page Test
MMU Protected Page Test
Parity Test
Err 9: Bad parity should cause nmi
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
So, it suggests there's a problem with the CPU board. Does anyone have
a spare 3/180 or 3/280+memory laying around? Alternatively, I could
probably try to replace the "broken chip", assuming I can find a
replacement, and a decent enough documentation to see what's wrong.
And, yes I've already tried pulling out the other memory board in the
system, all the RAM that's left is (soldered) on the CPU board. I have
a feeling it's not the memory, however, which is the problem.
So, if anyone has something I could use - either documentation or
hardware - that would be much appreciated. : )

Hi Stefan
Sorry I didn't get back to you. Things got busy and
I've been away from the net over the weekend. It looks
like you need to make an adapter to at least disconnect
Pin 22 so the VPP level can't get to the chips pin.
The mask ROMs may have any of the 4 configurations for
pins 20 and 22. I would try first just disconnecting
22 from the test side and connecting the chips pin
22 to pin 20. This assumes that the mask ROM uses the same
selects as the EPROM does. I'd do that as the first try.
Does anyone remember which pin they pull high on to
check the manufacture ID. I think it was A11 but I'm not
all that sure. It would be a good Idea to stack two
resistors of about 1K in series with this lead. One
should place a diode to VCC ( pin 28 ) to the junction
of the two resistors with the band towards VCC. This
will protect the part against any ID test voltage that
might be used. It would still allow the address to pass.
