MITS Altair 8800b switches needed

Since Erik brought it up..

I could also use a couple switches, but in my case they are for an 8800A
model. (Well, it's sort-of a 'B' now as it was upgraded to the 'B' power
supply, but it still has the original 'A' type D/C board).

Like the 'B' it uses mostly Mom-Off-Mom mini-toggles, with panel mount
bushing, and the long solder terminals that solder directly to the PCB (not
the small eyelet type). But the handles are the standard mini-toggle bat
handle - not the flatted paddles Erik describes.

Any leads, feel free to mail me off-list. Thanks!
