Half on, half off -- New CD-R drive and 512-byte blocks

Looking carefully I see that it has 5 pairs of configuration jumper pins. Three for setting the SCSI ID, one for termination, and one "test block do not jumper". Your guess is as good as anyone else's. carl -- carl lowenstein marine physical lab u.c. san diego clowenstein(a)ucsd.edu

Half on, half off -- New CD-R drive and 512-byte blocks

If it's an IDE type, you'll probably best forget it. I should have mentioned that -- it's SCSI, of course. > However, I'm not a CD-RW fan because of the media cost. BEGIN off-topic-moment The only reason I'm particularly interested in the RW capability of this drive is for some experimentation with Linux on a Sega Dreamcast. I have it booting from CD-R, but if the Dreamcast will use an RW disc, it may save me money and coasters in the long-run. END off-topic-moment Perhaps it may also be useful for transferring data between two systems with these drives (...or mine is an external, so the drive could be carried), in the absence of a better removable media solution. I must admit that last time I saw them, they were megabyte-per-megabyte cheaper than any other common re-useable removable storage. > If the drive manufacturer can profide the command set and you > can figure out > how to create a driver for it for the target environment, you > can do what you > want.

I think that I should have been clearer here too -- what I'm wondering is not whether it will work with the environment, since I'm sure that cdrecord will compile and drive it in nearly any environment I'm likely to need. The question is -- in the case of my other drives going out, would it be possible to use this drive as the primary boot device for one of these systems. That, of course, requires the slightly odd (for a CD) block-size. It's likely that I'll just plug it into the VAX and try booting VMS from it -- that would answer the question pretty quickly. :) I was just hoping that somebody knew right off...

Does anyone have a live VT52?

by ajp166＠bellatlantic.net

You can use any dec terminal, set it to VT52 mode and then try the results. The Video SRM (dec internal) made the behavour a standard for all VT52/100/220/320 and all the rest.

need the use of a scanner with sheet feeder (near Seattle if possible)

Sheet-fed scanner for most stuff, he does use a hand-scanner for bound stuff. Like Eric, I'm pretty sure he does most pages as 600dpi line art. I just got doing the same for a section of a CDC manual that's in hot demand; then used Kodak Imaging to create a multi-page TIF from the individual TIF pages. Then print to PDF using Adobe Acrobat 4.05's PDF Writer. Yields a 367kb PDF, whereas multipage TIF was 2.1MB. > I don't see any taint on mine -- all the holes look the same > shape to me.

Without using Windows or DOS, the only CP/M you're likely to run on a PC would be CP/M-86, and yes, I've done it with a Zenith Z-150/151. -Douglas Hurst Quebbeman (DougQ at ixnayamspayIgLou.com) [Call me "Doug"] Surgically excise the pig-latin from my e-mail address in order to reply "The large print giveth, and the small print taketh away." -Tom Waits

DWBUA woes

I cannot guarantee that any of the UETs are fully >functional. Judging by the diags I see for the XMI<->BI equivalent widget, my guess is the diags do something like: "test I can see the VAXBI side", "play with the VAXBI side a little", "test I can see the UNIBUS side", "do data transfers". Since that's roughly the order the tests are numbered in for the XMI widget, if the same logical sequence is true for the VAXBI widget, I would guess that 0E means an "earlier" test failure that 12. >Anyone with any substantial DWBUA experience? Not me. I never broke mine :-) >I have the tech manual, Is it scanned - it may help :-) >but in the past, I just plugged it in >and it worked. Didn't have to >go at it step-by-step. Remind me what processor you are running this on. A Scoprio of some kind IIRC? Which backplane: 12 slot or 24 slot VAXBI? What exactly do you have in which slots of the VAXBI? The 8200 Owner's and Installation Guides are available at: http://208.190.133.204/decimages/moremanuals.htm (or they will be when it comes back up ...) Nothing obvious leaps out at me from the Installation Guide. There is a bit in bold that means "plug the cables into the M7166 the right way round, and mind they are delicate". There's another bit that says M7166 in first slot, UET in last slot and grant cards all the way along. And another bit that says "don't snag the cables when closing the UNIBUS cab" It doesn't say "make sure the four cables go to the right places" but the diagram on p4-28 shows how they should go. The DWBUA needs a transition header installed (but I presume you would not even have got this far into the tests without one!) Finally it says read the Tech Manual if the T1010 yellow LED does not light!! Antonio
