Can anyone add some info about Intel SBC computers (with Multibus) that ran iRMX?

[edit] Some notes

This is from my personal recollection only, so I won't put it on the main page. (I worked briefly in Intel Tech support for the RMX product line in 1984-85 but have had no connection with it since). Rob Burbidge (talk) 09:37, 12 February 2008 (UTC)

[edit] RMX88

I believe that Intel had a product of this name. It ran on the 8088 or 8086, i.e. the first generation of Intel 16-bit processors. It was simpler than RMX 86 and I guess that it was closely based on the 8080 product line (which I had no connection with). I do remember that mailboxes were primary means of interprocess communication. At a wild guess, with no references at all, I'd guess it was a near-straight port of the 8080 line of RTOS products?

[edit] RMX286

Don't know if this was the released product name but an Israel based dev team produced the first version of RMX that ran on 286 processor in protect mode. Source was based on RMX86 v6; the kernel was an extensive re-write but I was told the BIOS, EIOS and upper levels ported with very few changes, as a vindication of the clean design. It did have the capacity to break the 1M RAM barrier and access 16M, but the developers decided to use a single local descriptor LDT for the whole system image. While loosing the capacity for protection between jobs (processes) it did overcome a perceived problem with the 286 which was that loading and re-loading the LDT on context switching was relatively expensive.
