Not to forget the Sun SPARCstation 5, which came after the 10 and had the

Hi Sellam,
I have an Amiga 500 with a Commodore 1084 monitor. The cable I use is
a DB-25 to DIN-6 (5 pins around the outside, one in the center) - this
does give me color.
IIRC, the RGB output on the A500 is the rightmost DB25 connector when
viewed from the back, however, I'm pretty sure it's marked RGB or
something like that.
The Atari ST's use a honkin big circular connector - I recall it's
something like 13 pins (3 rows of 4 plus 1) - Best thing for the Atari
is to use an Atari SC124 (mono) or SC1224 (color) monitor. If you don't
have one available, you can build an adapter for a mono display on most
PC SVGA monitors (I build one before I found the monitors, and it does
work). Some of my ST's have RCA connectors for RF out, which you can
display on a TV (not nearly as nice).
Regards,
Dave

Hi Steve
Sure, but I have a DSP and I know how to program it.
I've not done CPLD's or FPGA's. It is just a matter
of what resources I have handy. I still think the
DSP is a little more flexible and friendlier environment.

Hi
I doubt one can fetch data with most PC's from the parallel
port fast enough to keep from being overrun, even on a byte
wise basis. That is why I've suggest the DSP. May of these can
run fast enough to do it on a BIT wise basis and
require no external hardware, other than buffers.

VaX enthusiasts,
I finally managed to get QBus SCSI card for my MicroVax II thanks to Ebay.
It appears like it will fit in fine. It says KZQSA M5976-SA on the side. It has two Centronix-50 Female connectors on it. Question is what is easiest way to connect this to internal full-height DEC SCSI drive with standard 50-pin connector. Get a f-f gender connector and a cable with Centronix-50 F connector on one end and ribbon with internal connectors along it, and terminator at end?
I cannot recall what model DEC drive this is, but I thought it was 4GB. How do I find DEC Drive model? I see numbers 74046725-0 A01 GM on side rail, 70-2988501 on top of drive, Model DSP5400S Rev RH12E-CY A01 on back of rail, and another label on the back of drive reading KB34426075 R-75. Board says 54-21265-06 A05 and ZG40516250 and 74P6 and Side 2 5021264-06 A01
I used to like programming in C and Fortran on this machine and the drive died a few years ago. I was hoping to load VMS on to the new big disk and have lots of space to play around in.
Thanks for your assistance,
Bradley Slavik
Hi all,
Does anyone here own or use a HP 1650B (or 1651B) logic analyser?
Do they need DSDD 3.5" disks or can they accept DSHDs as well?
I ask because someone has just offered me a HP 1650B - system disk, a few
pods and a 1650B analyser - but doesn't have any manuals or know what type of
disk it needs. I'm guessing DSDD-only, given that the system disk is
supposedly DSDD.
Is it possible to duplicate the operating system boot disk using standard
hardware (i.e. a PC or my RISC PC)?
Anyone got PDF versions of the Operator's Manual, Service Manual and/or
Programming Manual?
Sorry for the OT-ness of this message - sure, it's not a computer, but it
meets the 10-year-rule - the power-on selftest screen displays "COPYRIGHT
1987", so that would make the firmware, what, 16 years old?
Thanks.

Hi All
Another Los Alamos, Sandia Auction this weekend. If you live within a
driving radius of Albuquerque, you should really check these out.
I unfortunatly cannot make it this weekend. :-( So someone else will have
to bid on the Sun Enterprise 450 :
http://www.bentleysauction.com/pictures/albuquerque/06-12-04%20Sandia,%20LA…
There are also several Ultra 10's 5's and 2's
As well as your SGI Octanes, O2's and an Impact 10000
Also a Digital RA90 Rack and a Vax 4000-400 and several MV II's
Complete list:
http://www.bentleysauction.com/misc/catalogs/nm061204.txt
And this time they even have some pictures:

Having been to these auctions before. This stuff goes real cheap!!
Have fun!!
Cheers

Please do not read this sig. If you have read this far, please unread back

Why does everything have to be so difficult?
I'm trying to set up an Amiga 500 for tonight's Computer History Museum
event. It's got a DB-23 RGB output and a Mono out. I've got an Amiga
1080 high resolution color monitor. It's got a Video and Chroma input,
plus a DA-9 RGB input. I've got an Amiga RF Modulator that plugs into
the DB-23 on the back of the Amiga and has a composite Video and Audio out
(and an RF out). Then I have several video cables. One is a DB-25 to a
DIN. Another is a DIN to three RCA leads. And then there's the DIN to
DA-9. At least one of these might be for the Atari 520ST (which I also
need to set up).
None of this connects up in a way which gives me colour on the display.
Is it too much to ask to have products designed by people who are not
insane?
