What's the best way to slurp up DEC RX50s?

Jerome Fine replies: I thought the model number sounded familiar. I received a few 5 1/4" HD 1.2 MByte floppy drives recently, but have had no time to check them out. I think that at least one is the FD55GFR. I also have two of the RX33 (actually labeled as such by DEC) inside the shell of an RX50 (vacated since the RX50 was bad). A Y power connector and a 34 pin cable with two edge connectors at one end allows BOTH to be easily connected to an RQDX3. Initially at first glance, it looks like an RX50, but closer examination shows the handles for HD drives rather than the shutters for an RX50. That is the obvious reason. But for myself, I am NOT very interested in hardware as such. So anything that works is the best and only solution. I have enough software bugs and enhancements to keep me busy for a couple of decades. Since I use BINCOM 99.9% of the time to make sure that every image that I copy from an RX50 (or any blocks at all for that matter) has been copied correctly, there is not much reason to have two drives. It takes just about the same time to copy an RX50 image to a temporary location and then back to a second media as it takes to do the copy using two floppy drives. When I include the BINCOM as well, the time is almost doubled (almost since my version of BINCOM is usually able to do a compare faster than the COPY - I use very large 96 block buffers and I also double buffer - reading into the next buffers while I compare the current buffers). It takes 152 KBytes of extended memory under the RT11XM monitor, but the result is work while. The only time it is a problem is when I must keep the buffers in the 18 bit address area for an 18 bit device and that memory is already being used. I fixed the DYX.SYS device driver to use a bounce buffer, but others have not yet been fixed.
