Did someone on the list buy the pair of source RK05's on eBay? https://www.ebay.com/itm/PDP-11-Program-Monitor-V10-02-CUSP-and-Device-Driver-2xRK05-DEC-Digital-PDP/353391043210 I bought the fortran source disk that was listed at the same time, but didn't go after these because of the cost and I may already have it in the archived DECtapes on bitsavers.
