Re: SGI Personal Iris information
Greetings, im not sure if it would be of help, but i know someone who is quite far along with an emulator for the sgi crimson. He bought my sgi crimson a while ago and has been reverse engineering the hardware. Not sure if that would be of help, i could put him in contact with you if needed.

Re: Box of HP 1000 series MUX cards - 12040
I'm curious. I'm not a HP fan but I do have a 21MX in my collection. I've run it enough to see that the front panel is working with some RAM. My question is, why would anyone use a MUX card ( in other words what are they used for )? The next question is even for someone that had a use for some, why would they want to buy 87 of them? As for gold value, the offered value is closer than many I see on ebay. I don't know how much gold there is, counting chip packages and such but less than $7 per board seems closer than some of the offers I've seen, on ebay. I can understand from a business point of view, the desire to get some value from them but at 87 boards, once the value of scrap is determined, that would more likely be where they would sell to. Expecting collectors to take on 87 units to get one or two makes little sense. I tend to agree, it seems to be a disingenuous offer, at least for HP1000 enthusiast. As scrape value not so disingenuous.

Re: Box of HP 1000 series MUX cards - 12040
I'm not understanding your sentimental attachment on these mux cards. You can buy them all, bring them home, read to them before bed time, and take great care of them until they get older Nobody I have sold to in the 25 years of selling this older HP stuff has said they can use 1k MUX cards.. Believe me I have asked, I want all my hardware to find a great home but the inn is full and things have to go. The older HP boards have some gold in them, thats why I made that ad and a bump on here. That stuff will sell, might be a week, a month, a year and at a lesser price but someone will buy it. I don't mind you trashing the ad but me? I provide a service for this older HP stuff, there are not too many more of us out there that know ins and outs of 1k, 3k, 9k hardware. I buy this older stuff from anyone... people on this list included. Am I complaining, no because if I want something, I know there is a price. Lastly, you have no idea what the cost into these board are, you act as if I found them in a dumpster. These thing carry a cost that they were purchased for... excluding housing, storing them, shipping them when we move for past 15+ years. Its very different than rescuing (=free) a box from the crusher.. Even still, I wouldnt mind if you sold your rescued box or parts from it.

SGI Personal Iris information
I'm currently working on emulating the 4D/20 in MAME, and looking for anyone who might have actual hardware, software or documents that might help. Right now, most useful would be some high resolution images of the system boards, especially the GR1 graphics boards, or even schematics if they're out there. Appreciate any information or input at all. -- Pat.

The only value they might have to me is in the individual parts populating the boards themselves, which might be cannibalized to save useful boards. Not everything can be saved. - J.

Re: Margaret Hamilton Guardian interview.
> From: Richard Loken > I have never heard of her before and had no idea. There are two books from participants in the development of the AGC software (both of which I highly recommend) which mention her: Hugh Blair-Smith, "Left Brains for the Right Stuff: Computers, Space, and History", Sdp Publishing, East Bridgewater, 2015 Don Eyles, "Sunburst and Luminary: An Apollo Memoir", Fort Point Press, Boston, 2017 The latter has somewhat grumpy note (pg. 342) which points out that she was only appointed to a management role in early 1970, after the first landing. It also points out that Hal Laning originated the concepts of "asynchronous software" and "priority scheduling". Eldon C. Hall's excellent project history, "Journey to the Moon: The History of the Apollo Guidance Computer" (which covers both h/w and s/w) doesn't mention her. Noel
