SE/30 parts


Hello,

Does anyone in North America have a use for a CRT and/or
analogue board for an Apple Macintosh SE/30?  Free to anyone
who is willing to pay postage.

SCSI/IDE laptop adapters

(I'm sending this to five lists, the five lists that I think most
likely to have an interest in such a thing - ie, the ones most likely
to be using machines built during the era when SCSI laptop disks were
popular enough to be used.  Since followup discussion on some lists is
likely to go in directions not appropriate for other lists, I've set a
Reply-To: address which is a bitbucket; please fix it if/when you
reply, to send to just the list appropriate for your reply.)

I have a SPARCstation Voyager, which unfortunately has a fairly small
disk (773 MB).  But this machine uses SCSI disks and has space for only
a laptop-form-factor drive (well, unless you want to go external, which
is rather suboptimal).  I understand there are other machines in the
same boat, such as some Mac laptops (I don't know whether they're
PowerPC or 68k - or perhaps some of each - which is why I'm sending to
both the macppc and mac68k NetBSD lists.)

I did some searching and found there was a company that made an adapter
that fit next to a modern (thin) laptop drive, so the result was a
somewhat thickish "disk" that still fit within the old laptop form
factor - but which spoke SCSI to the host even though the disk was IDE.
Most of them were fairly expensive, but there was one that looked
reasonable.  The vendor that was said to carry it, though, no longer
does (I phoned them and asked), so I wrote to the manufacturer.

They offer to sell them to me at US$65 apiece, quantity 10.  I'm
willing to pay that rate, but I have no need for more than maybe two.
So I'm wondering if people would be interested in buying these off me
(at my cost, which probably means about USD 70 including shipping, at
least within US48+CA).

Have you considered trying one of those newfangled 2.5" SCSI RAID array 
drives?  There aren't that many around that are straight SCSI, since 
most are SAS, but you should be able to find some, and they should be 
more than big enough.

Peace...  Sridhar

Another option (if slightly suboptimal as well)... network storage and 
booting?  These machines aren't that fast to begin with, so using network 
booting shouldn't be that awful.

Documentation for graphics cards

Hello,

I'm currently trying to improve the framebuffer used in port-mac68k  
to bring it into the current century (i.e. full wscons support and  
drop rcons).  I already have it mostly working using genfb (thanks,  
macallan <at> !), but it'd be nice to improve it some more by using device- 
specific functionality.  Otherwise, colors do not appear correctly,  
for example.

So... as the Mac I have claims to have a "valkyrie video card" (that  
is, the one I can try), does anyone know if there is/have any  
documentation for it?  Do you have any documentation for any of the  
other supported video cards?

Thanks!

Re: Documentation for graphics cards

I don't know a thing about that specific card, or much of any of the
video cards out there for macs of the era, but I do have a few various
ones laying around that I will be *glad* to donate to the cause.
wscons would be *amazing* to have finally, not to mention a real color
X server!

If there is any way I can help, please let me know.

If I'm successful with this card, we can look at these other cards  
later :-)  But first I must get one to work.

> If there is any way I can help, please let me know.

Well, I'd certainly welcome a full-features 68040 chip (or two) --  
that is, with a built-in FPU.  The ones I have are 68LC040 and they  
are slow as molasses.  Plus some extra RAM for a Performa 475 (80 ns,  
72 pin SIMM) could be helpful too.  Anyone? :-)

Kind regards,

I used to work on this but I could never quite get enough time and motivation 
to finish the job. However, I can give you some tips.

You're in luck if you want to work on the Valkyrie since there used to be 
some code to support it on the PowerPC based 6300 in mklinux. I don't think 
there were any HW accelerated ops supported but there was code that enabled 
use of the CLUT/DAC, get the attached monitor type, and, I think, change the 
color depth mode.

So your best bet to get Valkyrie support going is to grab an old copy of the 
mklinux sources for the old PPC macs.

There's a valkyrie driver in the current linux kernel, no need to go 
digging:

have fun

I'd be happy with even a 4-bit X server that worked consistently on all 
mac68k, as long as it was BSD licensed so it could be distributed.  The 
present situation is kind of sad.
