Sun Microsystems Hardware

	Sun 19 Inch Grayscale Monitor Cleanup Sun supplied 19 inch grayscale monitors that were largely the same as their ECL offering, but with analog inputs. This one also required a cleanup and recapping, like the ECL version.
	Sun 511 SCSI Shoebox Rebuilding and using an empty Sun 511 SCSI shoebox enclosure. This shoebox came up on a mailing list with no drives, and ended up being quite a bit of work!
	Sun 19 Inch ECL Monitor Cleanup After searching for quite some time, I finally acquired a Sun 19 inch ECL monitor! This monitor arrived working, but did require cleanup and repair before serious use.
	SPARCstation 2 and IPX RAM Upgrade SPARCstation 2 and IPX systems are closely related, and max out at 64 MB RAM on the motherboard. There exists a somewhat rare RAM upgrade, in SBus card form-factor, which allows these two machines to be expanded to 128 MB!
	Sun 3/50 System with Upgrades The Sun 3/50 was Sun's lowest-end Sun-3 offering. These limited systems were intended to be (relatively) cheap diskless workstations in environments like computer labs.
	GW-48T02-1, a Module for Rebuilding the 48T02 RTC/NVRAM With a large number of vintage Sun machines in the shop, I was stuck with having to repair or replace dead batteries in the 48T02 RTC/NVRAM modules used on many early SPARC systems. Modern replacements are not 100% compatible, so the old modules have to be repaired. There are clearance issues in some Sun systems, so gluing a coin cell holder onto the old module was not an option. I decided to lay out a small PC board to completely replace the "CAPHAT" section of the 48T02.
	Repairing Sun SPARCstation IPC Power Supplies A recent equipment pick-up included many Sun "lunchbox" form factor computers, including two SPARCstation IPCs. Both of the IPCs had dead power supplies, a result of failed capacitors. After recapping, they functioned perfectly. We'll cover which capacitors are valid replacements, clean-up, et c.
