RK11-D register address assignment

by Jos Fries

The "RK11-D and RK11-E moving head disk drive controller manual" (EK-RK11D-MM-002) states in par. 2.5 (Installation Procedure) that the register and vector addresses of a RK11-D can be configured by "seven interrupt vector address jumpers and eight address selection jumpers of the M7257". The manual however doesn't state the address range that can be configured by these jumpers and refers to engineering drawing D-CS-M7257-0-1 for that information. I found these drawings in the RK11-D Engineering Drawings but cannot find information in them on the valid address ranges. Therefore my question: what is the address range a RK11 controller can be configured for?

Looking for VAX/VMS v4.x Software

by Christian Gauger-Cosgrove

Greetings, Long story short, as the subject line says, I'm looking for some VAX/VMS v4 era software. I've been working on putting together a "turnkey" VMS v4.7 system — I've mentioned it over on the SIMH mailing list once or twice, and if anyone is on the ClassicCMP Discord server, Mainframe Enthusiasts Discord Server, or DEC Discord¹, you've likely seen me mention it multiple times — and I'm currently trying to copies of some of layered products. To the crux of the issue, does anyone here have — as an image, or media that they are are willing to image/have imaged — the installation media for the following software for VAX/VMS v4.x? • VAX NOTES • VAX P.S.I. • VAXset/DECset — specifically the Language Sensitive Editor • CGRAF and CIMI And just because I have a deep loathing for myself: • Eunice I'm also always open to any other software for VMS v4.x if anyone has any they want to share. Best regards, Christian ¹: "The Digital Equipment Corporation Fan Spot", as it's named properly. -- Christian M. Gauger-Cosgrove STCKON08DS0 Contact information available upon request.

G'day, I have a ThornEMI Datatech 9800 9-track tape drive. Has anyone a user- or service-manual or a description how to load a tape? This drive can load the 7" 9-track tape reels and has an industrial interface with edge-connectors P1 and P2. Thanks in advance Lothar

Re: Paper Tape Reader Needed

by Anders Nelson

Oh right, that's an important piece haha. I imagine fusing that Arduino project mentioned earlier in the thread with an SPI RAM chip and little extra firmware should be able to grab any length of tape one may have. -- Anders Nelson On Sun, Apr 13, 2025, 4:59 PM Mike Katz <bitwiz(a)12bitsbest.com> wrote: > Plus the circuit and software to operate it and convert the data to serial > or USB CID. > > On Apr 13, 2025 3:10 PM, Anders Nelson via cctalk <cctalk(a)classiccmp.org> > wrote: > > Here's a super cheap reader assembly you could bolt to a board, then hang > your supply reel from a bolt stuck in it if you're looking for the lowest > cost option: > > https://www.ebay.com/itm/224491588288 > -- > Anders Nelson > > On Sun, Apr 13, 2025, 6:49 AM Martin Bishop via cctalk < > cctalk(a)classiccmp.org> wrote: > > > The Sanyo Denki readers I have known use sprocket wheel feed, an > > additional means of damaging tapes. > > > > The Fanuc readers use a friction pinch, "rubber on steel", so they can't > > "saw" the tapes. > > > > Perhaps a consideration - if one has a choice > > > > Martin > > > > -----Original Message----- > > From: Chuck Guzis via cctalk [mailto:cctalk@classiccmp.org] > > Sent: 13 April 2025 02:18 > > To: Ethan Dicks via cctalk <cctalk(a)classiccmp.org> > > Cc: Chuck Guzis <cclist(a)sydex.com> > > Subject: [cctalk] Re: Paper Tape Reader Needed > > > > My PT reader is a Sanyo Denki, from a piece of CNC gear.
