Wanted to thank both of you for responding to my original request for

Our Tektronix 4051 can talk to and use Commodore IEEE floppy drives for
mass storage. It has a custom ROM extension for it.


That's really cool.  There are a few non-Commodore systems that were
able to talk to Commodore floppy drives.  I didn't know the Tektronix
4051 was one of them.

Do you know if it works at the flie level or the block level?


As you wish, but normally at the file level. You can OPEN files, load 
BASIC programs with OLD and so on.

The documentation is available here:
ftp://computermuseum.informatik.uni-stuttgart.de/tektronix/tek4051/

It's only in German, though. The disk routines are part of loadable 
extenstions that can be loaded into a RAM Backpack module.

Yep.  All PETs have true IEEE-488, albeit a software-driven
implementation so it's not high-speed (few kb/sec).  Starting with the
VIC-20, they used that serialized version, because Jack Tramiel was
tired of the cost of cables and connectors.

I think it could be done.  The IBV11 can certainly keep up with the
6502 in the drive that's banging out the IEEE-488 protocol.

You would need a box like that (they do exist) for talking to a later
device like the abundant 1541 floppy drive, but you could just plug
the cable right into an older drive for the PET, a 4040
dual-double-density 5.25 drive, or an 8050/8250 drive (higher density,
more tracks), or even a D9060/D9090 hard drive (5MB or 7.5MB,
internally has an MFM drive and a SASI-ST506 bridge).

The "DOS" is in ROM in the disk drives, including everything about
files and filesystem layout.  You wouldn't have to port that to the
PDP-11.  You talk to all the drives with the usual IEEE protocol of
secondary addresses and command strings.  On the PET side, it's
LOAD/SAVE, OPEN/CLOSE, and PRINT#/INPUT# (later ROMs added a command
layer for "disk commands" but they are just wrappers around the
primitive calls).

The directory is a special file named "$"; to get a directory, you
open that file and read the contents.  The drive sends the directory
not as plain text, but as a loadable BASIC program so you do have to
convert "line numbers" (file block sizes) to ASCII, and you have to
convert all the text contents from PETSCII to ASCII.  All doable in a
couple of pages of code.

There are a number of books for how the Commodore side works.  You can
even use the later serialized drive books to understand the higher
protocol.  At a character level, it's identical.

In terms of using it as a more generic device, there are block-level
primitive commands (U1 and U2 for read and write-block) but the
physical block size is 256 bytes, even on the D9060/D9090 hard drives.
I'm sure it's possible to write a native driver for RT-11, bypassing
the Commodore filesystem, but it sure would be slow.

Re: IEEE-488 on the PDP-11

[Sytse van Slooten via cctalk]

Hi,

Did you think of running MINC basic? That would almost certainly work, even if 
you don't have any other MINC cards in your machine.

Most elegant of course if you'd run the complete floppy image (to be found on 
Bitsavers), but I'd bet it will also just work if you extract the q4szmx.sav 
from those images and run that on just about any working rt-11. 

Can't really test it out though - the IEEE488 stuff is not (yet) in my FPGA 
implementation of the MINC - it doesn't look to be difficult at all, but I 
don't have any IEEE488 capable instruments to connect to :-/

There's a nice manual on IEEE488 in the MINC set too, find it here: 
https://electrickery.nl/comp/minc/doc/ 

Cheers
Sytse

I kind of want to see now if an IBV11 and Commodore 1541 can be abused
into cooperating. (There'd need to be a small "box of stuff" to turn
the real 488 bus to CBM's serial thing.)


I used to have an aftermarket drive for Commodore 64 made by MSD? that had 
both the Commodore serial AND the full GPIB IEEE488 interfaces.  I cabled 
that to an IEEE488 board on a PC, but then life got in the way, and I 
never got around to mastering it.

It can be done, but I didn't do it.

Re: IEEE-488 on the PDP-11

I'm going by the 'Instrument Bus Subroutines Programmer's Reference 
Manual' that is on bitsavers. [/pdf/dec/pdp11/minc]  In section 4, page 
4-1 it seems to imply that there are 6 files:


IBLIB.OBJ
IBSVER.FOR
IBMNC.SYS
IBNMNC.SYS
IBXMNC.SYS
IBXNMC.SYS

I think that's it.  *.OBJ is a library to link to, *.FOR is a test 
program, *.SYS are device drivers for MINC and ordinary PDP-11 SJ, FB 
and XM monitors.  It probably is on it's own disk (RX01 RX02?)

this package?  Or know where it can be found?

I recently wrote a driver for the IBV11 card under 2.11BSD. I have it
talking to my scope and logic analyser without issue.

https://github.com/AaronJackson/2.11BSD/pull/1/files

Not the cleanest code but my first try at writing a driver :-)

Cheers,
Aaron

I should have them in my MINC-23 stuff. If you can figure out which 
distribution diskette they're on, I can make you an image or copy.

IEEE-488 on the PDP-11

[Douglas Taylor via cctalk]

In my pile of DEC computer stuff I have a DEC qbus IBV11 IEEE-488 
controller board (M7954) with cable (BN11-A) that connects to the GPIB bus.


It would be interesting to try this out, but I don't have the DEC 
'Instrument Bus Subroutines' that work under RT-11.  Does anyone have 
this package?  Or know where it can be found?
