The 16500 and 16700 series are nice but the early models have the problem that they boot from 720k LIF format floppies and lack a hard drive.
Not correct. Only the 16500a boots from two floppies. The B amd C version have built in harddisk. It is easy to replace these old ide harddisk using a simple 4Gbyte compactflash card and compactflash to ide adapter. Boot from floppy , format drive and copy the files over. Done.
The machine will boot fast.
Usability is limited to the 9 inch touchscreen unless you eother get the network card or the 16505 prototype analyser. That machine is essentially an x-server running on a pa-risc processor. It has its own ide drive and boots a hp-ux installation. It can drive a standard vga screen up to 1600x1200. It interfaces over the scsi (hp cals it the fast acquisition bus) but it is scsi to the 16500b or c. Then the machines are really usable.
The 16700 do away with the old motorola 68k as in the 16500 and put a Pa-risc at 150mhz running hp-ux directly in the machine. 16700 requires external monitor. 16702 have built in for version A and even touchscreen for B. there are ram upgrades (option 003) to allow for 1600x1200 on an external display.
The 16500 series uses hpil keyboard and mouse and are hard to find. The 16700 is ps/2 but not all ps/2 keyboards work. Get an old hp keyboard (the curved ones). If the machine does not want to boot then the keyboard is incompatible.
The 16700 and 16702a needs an external scsi1 cdrom to recover it. The 16702b has a built in one.
All the 167xx run the same firmware. It looks like windows 3.1 but is actually hp-ux. the machine has an x-client. So you run an x- server on the pc and remote control it. Works perfectly fine.
Alle 165xx cards work in the 167xx
The 16900 series is a different animal. That is pc based and runs win xp or win 7. It uses a coprocessor board. In pci busmaster to translate the RIO (that is what the backplane bus for the analysers is called. Essentially a very wide data and address bus) into pc memory space. I have posted a teardown of my 16900.
Only a few select 167xx series cards work in the 169xx series. Notably the 16750 and 16760 work. The rest doesnt. 169xx are -very- expensive even used on ebay.
The 1680 and 1690 are stripped down 16900 with two or four channels in it . Not modular.
The 16500, 16700 and 16900 can be expanded using an expansion chassis (each type has its own) for a total of 10(165xx and 167xx) or 12 blades(16900)
There exists a timing correlator box for the 167xx and 169xx. This allows an infiniium scope and the logic analyser to be time synced. Either the scope or the analyser can fire the common trigger. The scope and analyser run in lock-step so you can capture analog and digital domain synchroneously. You connect both analyser and scope to the network, give them each others ip address and the logic analyser will clone the captured data from the scope so you can visualise it on the same waveform viewer. Most of the infiniium scopes with software 3.7xx or later can do it. Although it works best with the deep memory infiniums like the 54631 54632 and later machines.
A 16500a chassis can be found for 50$... Plus expensive shipping. These beasts weigh a ton... A b version goes for around 100$. A 16700 can be had for about 200 to 250$ while a 16900 will set you back 500 to 600. (Without blades).
Blades for a 165xx start at about 100$. The 167 series blades is 500$ and more while 169 blades sit well above a few thousand $...
