What was restarted as a pilot project more than four years ago at Stromasys is now a full-fledged product. The CHARON-HPA/3000 operations inside Stromasys are receiving continued investment, according to company officials. The emulator is a proof of concept project at several companies who've contacted us, but it's a full-fledged software solution at the vendor which created it.
The software's starting to caper through springtime on laptops and low-cost desktops across North America and elsewhere. One manager who briefed us about the POC work at his site said he put up the A-202 Freeware edition on an HP desktop with an i3 Core Intel chip. The desktop came off eBay with a $150 price tag. The demonstration yielded "a sigh of relief I could hear across the room." Top IT managers are happy to see a way for MPE applications to run onward into the future, independent of HP-built servers.
Installing the emulator software and setting it into service requires an ability to know how to put an IP address into a terminal emulator, in order to connect over a network. Any A-202 freeware users who have limited networking skills are presenting special support needs to Stromasys. The company says it's working in a couple of directions to find a method to help such users in a cost-effective manner.
Stromasys has two versions of the HPA/3000 documentation, one for the A202 Freeware Edition and one for the Demo-to-Production Edition. The company is restructuring these documents to turn them into User Guides, an upgrade from the comprehensive collection of notes available at the moment. Fortunately there are very few issues that only concern Freeware users, so having to spend time supporting freeware users — with advice and instruction that doesn't benefit the vast majority of its customers and prospects — has not been an issue.
Product manager Paul Taffel is at the nexus of this springtime growth. "The momentum is certainly building," he said, "and it really is fulfilling to talk to users who had no hope of finding a solution like CHARON, and to be able to show them such a high-quality product."
The HPA/3000 edition of CHARON will have a fresh release this spring, "and we have also started working on some major enhancements to improve our high-end performance."
Every 3000 manager uses either physical terminals, or a terminal emulators running on a PC (or very rarely on a Mac) to connect to their HP 3000. "This doesn't mean that they're running old-fashioned applications," Taffel said. "It's still the way that everyone who uses an HP3000 connects users to it."
Some sites may use fancy network connections to allow users running PC-based programs to access information stored on the HP 3000, without using a terminal emulator. But pretty much everyone uses software like Reflection or Javelin to open up a terminal emulator window when then need to log on to the system to issue commands or start up programs.
There are very few users still using serially-connected physical terminals (which require a DTC to connect to an HP 3000). Almost everyone who is using Reflection, for example, uses it to connect to their HP 3000 over a local network.
Contrary to our earlier reports, Stromasys believes the HPA/3000 will work with DTCs, although it hopes an enterprising user to try to hook one up and report their findings. And while Alan Yeo has reported that CHARON won't work with DDS tape drives, Stromasys says that's not true.
"My home test system — that $1,300 one — has a DDS-3 drive built in," said Taffel. "Warren Dawson (our first user) built his test system with a tape drive, but then decided against building one into his production system."
VMware can demand some close management in a few cases. When the CHARON Freeware Edition is run inside VMware on a laptop, users normally connect to the virtual HP 3000 machine by running Reflection on the same laptop. Despite the fact that Reflection and CHARON are running on the same physical PC, you connect them to each other using the network. If your laptop is plugged into a wired-network, Windows is provided with an IP address on the network -- and you must configure your virtual HP 3000 to have an address on the same network. When you do this, Reflection can talk to CHARON with no problem.
In VMware, things get much more complicated if your laptop is connected to a network using a wireless adapter. Stromasys has solved the problem of connecting Reflection to CHARON using a laptop connected to a wireless network.
If that laptop isn't connected to any network (wired or wireless), then connecting Reflection to CHARON requires yet another solution. This configuration is also being documented as part of the User Guide.
Freeware users of HPA/3000 are providing opportunities to solve problems such as wireless access points from inside VMware, and document it for the greater good of the 3000 community. Freeware users expect support for their experiments with emulation.
