How did the board work out? One of my few computing regrets is never getting to play around on that machine, although I love the Mac. I did get a Rainbow 100B years later, so I got as much of MS-DOS (3.10b) as I wanted. Decided I liked CP/M 80/86 better, and the Rainbow did that too. -- - Mark 210-379-4635 ----------------------------------------------------------------------- Large Asteroids headed toward planets inhabited by beings that don't have technology adequate to stop them: Think of it as Evolution in Fast-Forward.

I decided that way because that price beat Ciarcia Circuit Cellar's price for a *kit* for an 8086 SBC, and the 68000 looked more powerful to me than the 8086. I mistakenly thought that I'd be writing most of my own software in either case - and I've yet to really learn any assembly language. I totally misjudged the development of MacOS and applications, or the speed at which MS-DOS' hardware requirements would advance ... Anyway, my point is that exceptions to Apple pricing did exist, and were (at least in my case, though not necessarily for the right reasons) decisive. [1] I was going to say, "I still have it", but on thoughtful consideration, I guess I only still have the bottom and front bezel of the case and the CRT. Power supply re-built, logic board upgraded to Mac Plus which required replacement of case back. Not too sure about the frame - is that the same between a Plus and a Fat Mac? I still have the mouse and keyboard and power cable. -- - Mark 210-379-4635 ----------------------------------------------------------------------- Large Asteroids headed toward planets inhabited by beings that don't have technology adequate to stop them: Think of it as Evolution in Fast-Forward.

Keyboard with skull and crossbones key (U11)

by barythrin＠gmail.com

Anyone know what keyboard this is/was and if it was really standard? One of the dudes collecting stuff at Electronics Plus last weekend I think got it for a collector friend who's on this list. There were two of the keyboards, obviously from some government terminal/system but only one had the key. On top it was a skull and crossbones but on the user facing side it I believe said U11 as with most of the keys up there so it seemed legit. Thought it was funny but can't find much mention of it out there. Alternatively if you have it and have a pic somewhere I'd love to see it again :-) - John
