So you reckon those 7105SY9V3BE would suit the Altair? OK I'll go shopping.

I've had a wee Google for Altair pics and mine seems to be an oddball.
Most of the pics I've seen have all the switches the small type with
rounded 'baseball bat' ends. A couple had all the switches the larger
type with rectangular 'cricket bat' ends. Mine is the only one I've
ever seen with a mixture; small switches for address and data - large
for the control switches. See:


Anyone seen another like this?
