Talk:HLH Orion

4.1BSD?
I'm slightly dubious about the assertion that the microcoded Orion ran 4.1BSD. My recollection of Heriot-Watt's Orions circa 1990 is that the microcoded Orion ran "OTS 1.485" and the 1/05s ran "OTS 2.148" and both were ports of 4.2BSD. Maybe only early Orions ran 4.1BSD?

I'm pretty sure that the microcoded Orion in the labs in York circa '86-7 ran an OTS that was 4.1-based. OTS 2.x was (to the best of my knowledge) 4.2 with some 4.3 extensions. (and a very broken Green Hills C compiler)! Pete Fenelon 17:43, 27 January 2007 (UTC)


 * As we at least agree they were both called OTS, I've revised the article accordingly. Letdorf 14:18, 30 January 2007 (UTC).

Early employees of HLH.
FWIW I, https://en.wikipedia.org/wiki/Paul_Leyland, am one of the two "computer scientists" mentioned in the Grauniad article given in Ref-2. The other is Steve Thomas.

Steve did most of the Unix port and it was indeed 4.1 BSD at first. I wrote many thousands of lines of microcode including the standard instruction sets and at least parts of several others. Of the porting effort, I only did Franz Lisp as far as I recall (it's been a long time).

Also FWIW, David Small died earlier this year. Obituary at https://www.oxfordmail.co.uk/memorials/death-notices/death/30606294.dr-david-small/

Unfortunately I don't have much in the way of physical relics and could only contribute a number of reminiscences to the article. Xilman (talk) 11:33, 11 June 2024 (UTC)
