need interface to CDC Keystone (92185) tape drive

by elson＠pico-systems.com

Hello, I was referred by a member, Peter Wallace. We are trying to recover some programs from 9-track backup tapes. I have a working 92185 drive, and had salvaged a SCSI - Pertec formatted interface converter off the back of a Cipher 990 drive at work. The Cipher 990 was total crap, hardly ever worked. The SCSI converter actually worked for a while, I was able to read a few blocks of tape (without a proper program to handle the format, I just did stuff like sudo cat /dev/st0 on a linux system, and got info that looked like the first couple records off a tape. Then, the converter died, it stopped passing its internal self test. But, I had proved the 92185 drive is OK. So, now I'm looking for a way to read these tapes. The best solution would be an off-the-shelf SCSI - Pertec converter, which were made some years ago, but will be hard to find on eBay or such. Another way is to find the SCSI interface board for the 92185, but I've never found one to buy. Another way is to get my Vaxstation running again, the hard drive blew, so it would take some effort to get that back up. I have a Dilog DQ15 controller for it, and if that won't work, I probably have another tape controller, too. Another problem with the VAX is I'd have pull all the data off the tape over a serial interface, it was last running VMS 4.7 without TCP networking. Anybody got any goodies in the basement, any good ideas of how to interface it, etc.? One other choice is to build my own FPGA Pertec interface. The formatted Pertec interface is about as simple as you could imagine, but I'd need to add an SRAM buffer to the FPGA to handle up to 64K byte blocks. Jon

AFAICR, you can not > simply install the RA70 in the SA72. Hum. Correct me if I'm wrong, but isn't the SA72 the box that holds up to 4 RA7x drives? Same physical size as one RA90? If so, then no, it don't hold 4 RA9x drives. Also, the RA70 works just fine in it, as do all RA7x drives. RA70 is somewhat unique, though, in that it was designed to also be usable without any front panel at all. So there are dip switches on it that can be used to set the unit number.

Unidentified Emulex card from 1991

by dennis_mailing_lists＠conus.info

Hi. I got unidentified Emulex card from, probably from 1991. It is 16-bit ISA, it has two connectors male DB-25 and male DE-15F (like on VGA cards, but male). It is probably multi-port card, but I'm not sure. Here detailed photos: Label: http://yurichev.com/non-wiki-files/unknown-emulex/emulex1.jpg Component side: http://yurichev.com/non-wiki-files/unknown-emulex/emulex2.jpg Back side: http://yurichev.com/non-wiki-files/unknown-emulex/emulex3.jpg Connectors: http://yurichev.com/non-wiki-files/unknown-emulex/emulex4.jpg Does anybody here know what this is and whether it's possible to get manuals?

The 765 works just fine with 128 >byte sectors in FM mode. So Chuck ... do you know exactly how this works (as opposed to how it is documented)? 128 bytes/sector is a special case in the 765 (at least it is documented as such). According to the NEC documents, for the sector read and write commands, if you give it a value of 0 for 'n' (6th byte of the command = Number of bytes/sector), the actual number of bytes read/written is determined by the 9th byte written 'DTL' (DaTa Length). The docs don't go into much detail, and I haven't fooled with it much - I just set DTL to 128 when I am reading or writing 128 byte sectors (n=0). A few questions which are not clearly answered by the docs: under "READ DATA" "When N=0, then DTL defines the data length which the FDC must treat as a sector. If DTL is smaller than the actual data length in a sector, the data beyond DTL in the sector is not sent to the data bus. The FDC reads (internally) the complete Sector performing the CRC check, and depending upon the manner of the command termination, may perform a multi-sector read operatiohn. When 'N' is non-zero, then DTL has no meaning and should be set to FF hexidecimal" under "WRITE DATA" there is mention of N=0 or DTL ... but DTL is shown as a part of the write commands, and generally described as "DTL - Data Length - when N is defined as 00, DTL stands for the data length which users are going to read out or write into the sector". The read description seems to imply that the FDC "knows" the actual length of a sector, and only reads the number of bytes specified, while calculating the CRC over the whole sector. - How does it "know" the sector size ... the 'n' field in the ID header is the only place in the sector data that defines the size. - Does it assume the sector is 128 bytes? - or Does it actually read (and check CRC) on a smaller sector? -What is the actual behaviour during write? - Does it fill the remainder of a 128 byte sector with some value? - or Does it actually write a smaller sector? under "FORMAT TRACK" (in the chart notes) "(3) In MFM mode the FDC cannot perform a read/write/format operation with 128 bytes/sector (N = 00)" This implies that 128/MFM simply doesn't work - not even for format (which you indicated earlier actually does work). Is this a fairly reliable assumption? Does DTL have any effect on 128/MFM reads or writes? You mentioned that 80 bytes get transferred instead of 128. Does changing DTL make a difference? Or is it always 80 bytes? Dave -- dave12 (at) Dave Dunfield dunfield Firmware development services & tools: www.dunfield.com (dot) com Classic computers: http://www.classiccmp.org/dunfield/

Reducing my DEC collection (UK)

by toby＠coreware.co.uk

Hi, I've decided I'd like to reduce down my collection of PDP-11 and PDP-8s and so I have the following that I may be prepared to part with. All the machines and parts are located in the UK and at this stage I'm interested in expressions of interest. Please bare in mind that the machines are for pickup from the UK and would probably be impactical to ship. PDP-11/05 - 5.25" form factor PDP-11/10 PDP-11/15 PDP-11/34 PDP-11/34A PDP-11/35 PDP-11/40 PDP-11/44 PDP-11/70 PDP-8/E, 3 rack setup with 2 x RK05s, 2 x magtape PDP-8/L (missing its core memory card) Various qbus machines (PDP-11/03,11/23,11/73) Various TU56 drives PC04 paper tape drive PC05 paper tape drive Lots of RL01/02 drives RK05 drives All the best, Toby

DEC LP20 backplane wiring diagrams

by RichA＠vulcan.com

We have been trying to get working an LP20 printer interface on our 2065. We discovered just today that the issue we have had with bad control signals was not due to bad boards, but rather was due to the fact that the bottom 4 segments of the Unibus backplane into which the control card plugs have no (0) wires wrapped around the pins. We have the LP20 schematics, but the wiring diagram *for the backplane* is not included. It also is not to be found on microfiche, although there is a reference to it, with document numbers. We are specifically looking for 70-11427, 54-11704, and 50-11703. If anyone has any of these documents, please let us know ASAP. Otherwise, a young EE is going to have to spend time with the complete set of LP20 schematics and a spreadsheet program to generate a wire list and re-wire this thing by guess and by $DEITY, a process that will take several weeks with no guarantee of correctness of result.

Hi Liam, I am not sure if it does make much sense to address these polite "concerns" by the other chap... :) If the person making this statement can make boards for EUR 20.- each we'd be delighted to buy from him. For sure such price would be possible when making 100,000+ boards. We do runs of 100, we have to pay for electronics recycling (WEEE) registration, we pay tax, etc. I am sure hobbyists only doing a few boards can get around such things, we can't. We can't get even near this figure. For the record: the board is EUR 90.-; EUR 100.- is with cables we also have to buy to resell them. The donations asked for are for the preservation project, maybe it would have made sense to read the donations text file enclosed. And yes, even MS Office has student and pro editions available, I don't see anything wrong in charging companies that can afford to pay more. They keep it free for private users, at least for our product.
