A 6TB hard drive, available for about $130 (or less), would be equivalent to about 60 of the 100GB BDXL disks, which seem to go for about $6 each, so $360 for around 6TB. And the hard disk will take less time to read and write. And the hard drive would take up less space. JRJ On 1/4/2018 7:50

Oh Darn (Re: early PDP-11/45 info sought)

Dang it - the dates fooled me. (blush) Sorry to get your hopes up, Fritz. Here is some more accurate information: The first set: The first page (the directory) is actually 6/76 in the revisions block. It is *later* than the one on bitsavers. Interesting, though: it actually shows

Thinking about PDP11 PC05 Emulation

I have several PDP-11's in my collection (among other things), and not enough PC05 tape readers (or enough room) to go around. But most if not all of my machines have M7810 PC11 interfaces, and I have one I could move from machine to machine as needed. Moving a PC05 around would be a lot more

Re: Thinking about PDP11 PC05 Emulation

Hi, Henk. Cool - so sort of the complement of what I am considering doing - your interface allows connection of a real device to a simulated hardware processor. Your thorough documentation will be helpful in confirming the signals I plan to use. JRJ On 3/11/2019 1:39 PM, Henk Gooijen wrote: >
