The documation readers are somewhat available nowdays,
coming
out of election use.
There have been a bunch coming out on eBay lately but they have been asking
$300 & up. I am glad to hear that there is a reason and maybe if there is a
flood of them then the price will come down. The Four-Phase Systems IV/70
used to use these to boot a system that was being used for terminal
emulation only - had no disk or tapes. Mostly they used the smaller unit
that was about 80 cards per minute. The ones showing up on eBay are larger
300 CPM units I think, though just from a distant photo you can't easily
distinguish the 600 CPM model.
HTH,
Gil
