Hi ALL,
I see many peoples these days want to build own pdp-11 (this is kinda obsession). This
trend results in rise of prices on qbus hardware. The cpu, slu and memory boards are still
affordable, BUT storage adapters/drives prices gone mad (probably forever). I know, there
are some relatively cheap DSSI adapters for the QBUS-vax
machines, they emulate MSCP. So, once being configured on vax processor,
they hypothetically could be used on pdp-11. Also, there are some DSSI->SCSI
converters.
Is it possible to create and configure QBUS DSSI->SCSI (50pin) HDD solution for use
with pdp-11 processor? (What type of QBUS backplane needed? PMI (CD-interconnect) capable
KDJ11 processor? or dual height KDF11 card with simple Q22 would work also?)
I wonder what OTHER options are really exist?
p.s. I know about floppy and tu58 emulators, but those can not replace usual pdp-11 disk
storage in terms of speed/capacity (in case of hacked drivers for high volumes you are
losing compatibility).
