Sparcbook 3

This is the latest Tadpole system acquired from the fellow with some bits of this hardware.

I looked and found that there is an adapter for the Macs for the SCSI from something called HD-30 to SCSI2.  SCSI2 is what the 50 pin connector is now called.  I'm guessing it will be single ended, so should be able to use a Sparc 411 box, and a Plextor CD drive to install it.

This is equivalent to a Sparcstation 5, and is probably the fastest system likely to be had as a laptop by my collecting parameters (cheap, bargain).

Battery in nice shape

HD-30 Scsi Port can be seen at the left

Not sure if this is original to any Sparcbook.

The other sparcbooks somewhat wider and shorter supplies that are marked with a Sparcbook legend.  This appears to be the correct supply parameters, but not original to the sparcbook.  May be a sign the guy is running out of sparcbooks to sell. All of mine are coming from the same seller.

Vax VLC

A fellow on the cctalk group decided to thin out his herd of Micro vax systems, and sent out some to the list members.

This is the critter that is in my pile now.  I guess I will need to dig up more Sun 411 boxes and scsi drives or converters.

Hopefully will get an HP 16505 soon, and have a PA baby system to keep it company.  Maybe boot it on BSD, or dig up the pile of VAX if that is a supported system.

Modem, keyboard, options.  Are on Graphics daugher card

Celestron Nexstar GT with Astromaster tripod.

This is a tripod / nextstar mount made up from a few different pieces.  Basic mision is to carry a Nikon camera and lens and guide photos.  It won't be for long exposures, but for timelapse.

Also I have enough to mount a 5" F/5 on it, but it remains to be seen if it is going to be able to carry that.  The next larger 8" mount may be required to really carry the 5" mainly for clearance.

However the dovetail is compatable with a set of 7" rings and a crossbar that will mount the 5".

This would be very light for any photography of either type, but much easier to take out and set up quickly.

Tripod with Nextstar head installed

Nextstar head on legs, with original Astromaster

The original basic tripod head is on the Nexstar carrier, which is fitted to the legs.  Note that the original tripod head is maybe 1" smaller in diameter than the original.  This will make a more narrow stance w/o adjusting the eyepiece tray higher.

With the guidance pad.  

 There is plenty of room to move the eyepiece tray up a bit.  It may be stressed higher with a wider stance, and break.  The eyepiece tray and the three spanners are all plastic.
