[SPAM] - Re: Qbus hard disk controller - Found word(s) error XXX in the Text body.

... Note that none of the RQDXn have any BOOT ROMS, which is standard for a DEC controller as opposed to 3rd party controllers which usually have BOOT ROMS. And even the RQDX3

from a HD connected to it? I am ingorant about this

is difficult to use with any MFM drive except DEC RD5n and DEC RD3n drives. As for the RQDX1 and RQDX2, I don't ever seem to remember seeing one without a real DEC drive, although I have heard that XXDP has been patched to use a non-standard (i.e. non-DEC MFM drive). With regard to being able to FORMAT a drive with an RQDXn controller, normally special XXDP programs from DEC are REQUIRED! I should also have added that ONLY the M7555 board (RQDX3) is dual, the M8639 boards are all quad. In addition, the power needed is also very different. The quad boards require over 6 Amps on the 6 Volts while the dual board requires just over 2 Amps on the 6 Volts. While this aspect is not usually a problem, it makes like almost impossible in a VT103 when the TOTAL at 6 Volts is ONLY 16 Amps.
