There were some nice '386 and '486 machines out there. I actually got my

No idea if it helps, but if you're doing it really on Win***, you have
to make sure, you have administrator rights, and switch off any
virus-scanners, active-protection or whatever software which could run
in the background. They usually block the access to the first "tracks"
of a device, without any warning ...

Have the same problem, when I try to write complete sd-cards for my

And I don't expect people in this group to look for "fast". I think they

that finally somebody took the am9080 application note and put it into
an FPGA. It is a nice start to a lot of bit slice designs.

You can do this quickly and then go through the images to find something rather

I rented a Budget truck. They give you 5 days and you drop it at a local dealer.
A 24’ truck is huge. uHaul trucks have the “grandma’s attic” over the cab but

anyone is

interested: https://robs-old-computers.com/2017/07/15/decstation-5000240/

Unfortunately I didn't get a cable to connect the Extender to the main

machine.

I have a feeling they are hard to come by, does anyone have one that is

surplus

to requirements or know where I can get one?




I have not yet been able to locate one of these, although I now know the
part number, which is 17-03335-01.



Andf it is even in the UK:

Does anyone have such a cable and could check its pinout for me?

Thanks

Just as an aside on that, I doubt you really need the hard gold fingers
on a prototype board.  You do need something to stop the copper from
tarnishing, and hard gold is almost certainly the most durable option,
but I can't think of any obvious reason that an ENIG or immersion
silver finish wouldn't work just fine on the fingers for a moderate
number of insertions.

I second that one. Most of the time, your card sits on the adapter 
board, so if you break anything, it would be the connectors on the 
extender. So make it cheap, you will need few shots at it ...

Something like 700 nsec for a cycle (best case), so assuming 16-bit
transfers, a max of a little over 20 Mbit/sec.


From an old email from tim Shoppa who tested some QBUS SCSI controllers:

- cut --

I did (and published) some benchmarks of SCSI MSCP-emulating
controllers probably a decade ago. And indeed the CMD CQD 440 was the
winner. But they all beat the pants off a RQDX3!

Here are the peak data rates measured for read and write 64
blocks-at-a-time:


Read Write

Andromeda SCDC 2.298 MB/s 1.131 MB/s
CMD CQD440 2.397 MB/s 1.525 MB/s
CMD CQD220 1.418 MB/s 0.882 MB/s
CMD CQD220A 2.088 MB/s 1.409 MB/s
DEC RQZX1 1.379 MB/s 1.097 MB/s
Viking QDT 0.846 MB/s 0.704 MB/s
DEC RQDX3 0.164 MB/s 0.161 MB/s

The benchmarks were done under RT11FB 5.7 doing 1, 2, 4, 8, 16,
32, and 64 block-at-a-time READW's and WRITW's to 16384-block
data files. A KDJ11B (PDP-11/73) CPU with 2 Megabytes of Clearpoint
non-PMI memory was used for the bencharmks. With the SCSI
controllers a Barracuda 7200 RPM ST15230N drive was used; with
the RQDX3 a RD52 drive was used.

Yeah, but why 'waste' writes on swapping/paging activity, if there's a
RAM-disk ready to hand?


Use the memory as disk cache locally. Otherwise you need to write 
drivers for all different versions of OSs out there. Transparent cache,

write through ...

Then no changes are needed on the system

I think our plan was to skip that speed, and go with the next one down, on

From the top of my head (which is not reliable at this temperature) it

No, it isn't.

I think we're using the SPI at the moment, not the 4-bit (we discussed both,
but I _think_ we went with the one-bit to start with), but I could be wrong -
Dave will hopefully pipe up if I blew that one.


You use container files in fat16, or simply 1:1 block mapping?


IIRC our reasoning was that the SPI was the very simplest one to do, for an
initial implementation; if we later need the speed, and go to the 4-bit, all
the init/etc will already be working.


Sure.


> Did you wire-wrap this thing?

Yes (for one card out of two - below), but that wasn't the problem.

The problem is that we're using two cards (one to plug into the QBUS, and one
with the FPGA on it - surprise, surprise, nobody makes an FPGA protyping card
that plugs into a QBUS :-), and the two are connected with a cable; it was
the cable that was causing the noise (cross-talk - we neglected to put a
ground line between each pair of signal lines).


I agree some how with your approach, but it leads to debugging of 
issues, you wouldn't have on real boards ...

Is that just this particular product (individual SD/etc products seem to go
out all the time, as new and bigger ones come out), or industrial SD cards in

Don't worry, they stay around. Automotive/Industrial will be there for a 
while...



(Although we are going to include RAM disks as well, using the on-board RAM,
and suggest people configure their systems to do swapping/paging off the RAM
disk, to avoid wasting writes on 'temporary' data - although of course the
RAM disk should be faster, too.)


Now, we have to define on which system you are measuring it.
(pdp11/vax, local memory like 11/53 or 11/93?, etc.)

I'm not clear, reading this, if they use the standard SD-interface?

Yes.
Actually, whatever "standard" you just refer to. But the old 3v3 level, 
spi-derivative is very simple to implement. The 4-bit mode takes a 
little longer, the full speed 4-bit mode needs a nice layout.


If so, yes, it's non-trivial to interface to (as I previously mentioned, Dave
and I wound up defining a uengine, and writing a uassembler to produce code
for it, after Dave decided trying to do the init with a state machine was too
much pain).


Bit-Bang the setup, then think about DMA.

Tell _us_ about it! :-) (Of course, that issue we had with noise, and the
wierd latching inputs, made it even more painful...)

Why USB? Because then you can attach whatever you want, and you
have to write the USB stack only once, and then just improve.
And, USB with 480MHz is fast enough for the 3mbyte/s transfers on the 
QBUS/UNIBUS ...

Sorry to disagree, at least partially ;-)

Industrial grade sd-card are pretty good, and we are talking cards with 
less than 1gbyte per card. And still, backup is pretty easy, if you can 
take out the card, put it in another system and transfer the whole 
container file to you favorite backup media ...


That's also, why I always have at least two sd-card slots on the boards,
to have one "exchangeable" media in it, you can take out without 
stopping the system.



and the noise isn't an issue at all. Modern
drives just don't make any noise when used in a PDP-11 (or whatever
UNIBUS or QBUS system) ;-)


Probably listened to too many RD5x or similar in my life ;-)


BTW the problem with Fujitsu Eagle SMD drives is that they need a
complete lowlevel format from time to time. *All* Eagle drives I have,
have developed bad sectors that can't be read without errors even with
microstepping and other tricks.
