Those declared dead live longer – the ISA slot

IM-M98A9 mit ISA, PCI und PCI-Express Slots

“Never change a running system” – In times of ever faster technology development, this attitude seems to be losing popularity. The next generation is constantly entering the market. A good example is the ISA architecture in industrial computers: it had had its day in the conventional PC before the turn of the millennium. In industry, it is still needed for long-lasting applications.

ISA stands for “Industry Standard Architecture” and is a computer bus standard for IBM-compatible PCs. Developed by IBM in the early 1980s, it expanded the even older XT bus architecture from eight to 16 bits. For its part, it was increasingly replaced by the PCI bus in the mid-1990s. Since the beginning of the millennium, practically no new PC has had ISA slots. This also means that old ISA plug-in cards with system extensions, such as graphics cards, audio cards or measurement cards, can no longer be used in newer computers. Here the time of ISA computers is long gone.

The industry often still relies on the ISA slot

This is partly different for industrial computers: In contrast to the private customer area, “old” bus systems are used because the product life is much longer. Industrial PCs often do their unchanged work reliably for many years – they should and do not have to be upgraded to the latest system applications year after year. It is all the more painful when faulty and originally often expensive ISA plug-in cards can no longer be used in the new PC when exchanging computers. Complete plant retrofitting is expensive and would like to be postponed for a few more years.

The good news: As a manufacturer of industrial computers, we still have such an ISA slot. The technology comes from these days, it is of course new goods, no used e-waste “for hobbyists”. We can therefore offer systems that support MS Dos up to Windows XP and sometimes even Windows 7.

Two examples:

  • For example, the circuit board of the IAC-C860SA-870P has two, up to three ISA and three to four PCI buses. Otherwise, the computer works with an Intel Pentium M processor and supports MS-Dos up to Windows XP.
  • The computer IPC525-M98A9 offers one ISA, five PCI and one PCI Express interface. Up to the third generation Intel Core-i CPUs, quite high performance is even possible here under Windows XP and Windows 7.

The most important requirement for operating your old ISA card in one of our computers: existing ISA card drivers for the operating system you want.

Do you have to replace computers and want to continue using the proven plug-in cards with system expansions? Then an ISA-PC from Alptech is just the thing you need.

We would be happy to advise you!

Important reasons for renewal:

– Improved energy efficiency
– Security risks from outdated operating systems
– Computer hardware has a finite life span. Despite the high component quality, failures can occur after 4-12 years, depending on use / heat load.
– A complete depreciation for workstations and similar is possible after 3 years according to the German depreciation table AV.
– Unfortunately, we can no longer get spare parts for many old models.
