Ah, but my shop has all the game test fixtures (Bally-Stern (SAM 
IV)/Williams (6-WPC95)/Gottlieb (1-80C)) on benches, so we just roll up 
the 9010 on the 'scope cart and dig in!

So, these Series 90s are going to be useful to someone else, it's just 
in my shop they collect dust.

Along with Arium logic analyzers, Fluke 9100s (still trying to figure 
out the SCSI upgrade!), KK stuff, HP stuff...I've been collecting tech 
tools for many, many years...it's a long, long list.
