I've still got the 8800 I built (with all those crappy white stranded wires) back in the day.? It's not that great, trust me. I moved to an IMSAI box and finally to an Integrand box.?

An Altair isn't out of my reach.. just.. other stuff (like the Mark-8 boards) keeps coming up just as I've stored enough money to buy one.

pdp-11 assembly standards

What's the rarest or most unusual computer-related item do you own?

That is amazing Ian ! - Photo? Wonder what the ticket was for that back in its new day... Ed# In a message dated 1/10/2017 4:27:44 P.M.

It has six processors, and therefore is alternatively known as the VAX 6660 - the Devil's VAX. :-) I've not been able to boot it because I don't have three-phase power to my house. However, I've been informed that the H405 can be rewired to run correctly off dryer power, which I do have. That's one of the (many) projects on my post-dissertation list. With six processors and a half-gigabyte of RAM, I've been told this is probably the most built-out VAX 6600 remaining. -- Ian -- Ian S.

Boot Loader for 3P+S on IMSAI

by wheagy＠gmail.com

Took a little digging but I found the thread where you were talking about port 20/21. I was able to configure the 3P+S card and run the test from the solivant site successfully, but I'm not able to upload basic. I have a couple more things to try, including setting a small upload delay as Bill suggests on his page. http://www.vintagecomputer.net/browse_thread.cfm?id=318 However, I'm thinking that I may still have a configuration issue on the 3P+S card. But I think I'm getting close.
