How to mount HPUX 10.20 VxFS logical volumes in a modern linux environment
This is a problem that I’ve wanted to tackle for quite some time. Since I’m using SCSI2SD and also messing around with a few different logic analyzers, I’ve got several HDD images that include both...
Corrosion near/underneath HP Logic Analyzer module plastic runners
The problem is corrosion….. Corrosion appears to be happening either directly under or nearby the various sized (but typically 5″ long) plastic runners that line the bottom of the large PCB modules. These...
Effects of upgrading SCSI2SD from v5 (4.8.3) to v6 (6.2.1) analysis HP 16700A
If you compare this graph with the previous one in this post, there’s a few things you should notice: First, the overall boot is happening about 1 minute quicker, with a fully loaded chassis coming in around 2:35...
Day 4 of my assembly of A500++ PCB
I finally got my PLCC 84 socket in from Mouser out of stock and installed more EMI caps. Slow going…..made little progress on THIS project this long weekend, but I did make progress on other projects….. This...
16700A internals w/ SCSI2SD v3.0 installed
See my fan upgrade post here on quieting those noisy fans.

HP 16700A boot times and optimization
I’ve been playing with my HP 16700A Logic Analyzer and looking at boot times. Originally the HP 16700A came with an internal SCSI drive, which was still functioning after 15 or 16 years. This SCSI drive was a 4GB...
