Vintage Computer Federation has substantial experience recovering data from obsolete media.
We have the resources to read data off floppy disks (3.5″, 5.25″, 8″, and proprietary formats), disk packs (especially DEC), paper tape, and punch cards. We can also read data from most brands of 1970s and 1980s hard drives. In addition we can dump the contents of PROM chips and core memory.
Contact data.recovery@vcfed.org to discuss how we can assist you with extracting valuable data from obsolete media.
