I've managed to find the pieces (or at least the most important, which is one of my two RD54's) to do some performance testing on Doc's recent idea of using a network disk instead of a local disk to get better performance than a RQDX3/RD54 combo offers. As a result I'm trying to get either a VAXstation 4000/60 or /90 setup so that I can use it as the host. In doing this I ran into a slight problem with VAX/VMS V5.5-2, it doesn't like my 3rd party SCSI disks that I've got in the /90. Not a big problem as I've got some brand new (!) RZ25's that I can put into one of the systems, and I want to put a RRD42 into one of them as well. Stupid question, how to I go about getting the cover off of the 5 1/4" bay, and am I supposed to have another piece of plastic to go there? If it requires another piece of plastic (that I don't have), I'll just hook the drive up internally long enough to do the install. Now to decide which system gets a V5.5-2 install, I'll probably go with the /90 as it's my fastest VAX, and will therefore be the best for building software on. Zane -- | Zane H.

I have googled for an hour looking for them. No results.

DOS compatible mode for HP 9127?

by rigdonj＠cfl.rr.com

The HP 9127 is a HP-IB 5 1/4" floppy drive and normally it reads and writes a LIF format but there's supposed to be a way to have it read and write disks in a MS-DOS compatible mode. Does anyone know how to do it? I've been playing with different formatting options but so far I haven't found the right one. Joe

DaynaFile

by ericj＠speakeasy.org

Has anyone managed to find drivers for the DaynaFile? I have a couple I'd like to experiment with. One non-functional, unfortunately, but I pulled the rom on it to image it and attempt a disassembly. I have another that appears to work, or at least responds to a scsi inquiry. I plan to hook it up to a logic analyzer to get a memory map of the board. The logic boards on the two I have are simple, with common parts in clip-friendly 40-pin dip packages: scsi: DP5380 floppy: WD2793 micro: 8031 Documentation is available for all of these, so a person could potentially write new firmware. Probably much easier than disassembling the rom. I remember using a DaynaFile on a NeXT cube with an old (ca.1990?) version of Nextstep, so there are potentially Nextstep drivers out there as well.

resurrecting a PDP-11/10

by Andreas.Freiherr＠Vishay.com

Barry, didn't you ask (under the pseudonym of Fred Feuerstein) for a description of the switches on a DS120 Terminal Controller? I managed to find a user manual from the stone age, stating that the "Logic Card" is part number 512000-2. Not quite the 5120000-1 that you mention in your posting, but possibly close enough to provide hints for what functions might be there. YMMV... This is what the manual says about the DIP switches: SWITCH FUNCTION 1 Carriage motor disable (test only) * 2 Reverse channel override * 3 FDX/HDX override * 4 Local Auto-LF override ** 5 Parity odd (ON) parity even (ON) ** 6 Parity enable (ON) parity disable (OFF) 7 AUTO-LF from line (ON) disable (OFF) ** 8 X-on, X-off handshaking enable (ON) disable (OFF) * On DECwriter models with the 8-key control pad, these switches are duplicated on the keyboard. Those models with the 3 rocker-switch panel must control these features with the DIP-switches. ** See Appendix B, "Additional User Information", for a functional description of these switches. End of cite. Appendix B talks a lot about half-duplex modes, which I presume will not be used with your PDP-11. Hence, you will want to have switches 2 & 3 in the OFF position. The description of switch 5 obviously contains an error. For even parity, the switch needs to be in the OFF position (says appendix B). Another noteworthy cite: "If parity is disabled by DIPswitch #6 "OFF", then DIPswitch #5 provides 8th bit spacing when "ON" and 8th bit marking when "OFF"." In other words, you actually cannot select "no parity", but you can set "mark" or "space" parity. You report having trouble with the 20mA interface. Maybe you need to switch from active to passive or vice versa? - Here's what the manual has about it: 3.1.3 20 MA CURRENT LOOP A 20mA current loop interface is provided featuring a photo isolated receiver and transmitter. The receiver and transmitter may be configured to operate in either passive or active mode. Unless otherwise specified at the time of purchase, the DS120 comes configured with a passive transmitter and receiver. Although specified at 20 mA, the signal line currents flowing in the receiver loop may be as high as 80 mA without harming the interface. Any current in excess of 15 mA will be interpreted as a mark, and any current under 3 mA is interpreted as a space. 1500 volts of isolation is provided by the photo isolater if passive is employed. The jumper configuration for the current loop interface is as follows: W1 W2 W3 W4 W5 W6 W7 W8 W13 W14 ------------------------------------------------------------------- PASSIVE Out In In In In Out Out Out Out Out ACTIVE In Out Out Out Out In In In In In The connections for this interface are as follows: PIN 2: Transmit - 3: Receive - 5: Transmit + 7: Receive + End of cite. Hope this helps. If you need more information, I can get whatever is printed in the manual for you. I do have a LA36, but it features the original DEC controller board, so I have no way of actually trying anything. -- Andreas Freiherr Vishay Semiconductor GmbH, Heilbronn, Germany http://www.vishay.com
