Hello everyone. who can tell me what this 8bit isa card is for.
It's a Cambridge Research Systems AS-1.
Found in an ast lc bravo 4s/25 dating from 1993.
Thanks

Looks to be scientific or industrial data acquisition or control card. Analog inputs, at least some of them - I spy two DACs and one ADC with 4-channel sample/track/hold chip. And 186 MCU for local control - back then we didn't have Cortex ARMs so if you needed more program or data space than '51 could handle you went with 186 or some Motorola chip. Z80 could be used too but it also had 64k limit without banking so 16-bit core makes more sense with those SIPP banks.
I doubt anyone can guess what that card actually did unless they had/used one. I also don't think it's of much use these days without documentation and/or software...
Looks like they're still around: https://www.crsltd.com/how-to-contact-us/about-us/
And that supports Deunan's guess that it's some kind of scientific data acquisition or control card.
Perhaps drop them a line and ask if they can tell you what it is?
They may still have documentation on it, or someone still working there, who was around when that card was developed.
Hello everyone.
It was recovered in an AST Bravo LC 486sx25 from a laboratory in a hospital.
I suspect it was used to drive a medical analysis device.
Unfortunately, the 120mb hard drive of this pc was destroyed before my eyes for confidentiality reasons so I could not recover the associated drivers or software.

Nothing on the AS1, but probably along the same lines as the AS2 - https://web.archive.org/web/19980524144308/ht … td.com/as2.html
