It's all about priorities 8-) -Ansgar

Probably that's the way of life... once the kids are growing up they leave home :-) Anyway, would be cool to still post as much topics of general interest as possible also here in vinthpcom, even if t

According to the patent description, 9825 tapes are frequency modulated, Ones are encoded at 10.6 kHz and zeros at 17.6 kHz.

By the way, here is the usage for the krcb (record binary) program: rcb [<FILE #> [,<FWMD>,<LWMD> [,<TYPE> [,<LENGTH>]]]] [,<STRING> [,<TYPE> [,<LENGTH>]]] rcb <STRING> [,<TYPE> [,<LENGTH>]] (ie rcb O

Of course :-) -Ansgar

Hmm.. I don't think it is possible to copy a full 9825 tape content that easy. You probably will need to create your own binary program with an assembler program for direct tape access. If it is just

#HP9825

Guess there is not much of an alternative to read 9825 tapes with a 9825 system. If I remember correctly, HP used the DC100 medium within the following contexts: 2644A terminal (first appearance of th

#HP9825

Guess HP did not take it that seriously with the different labels, I have seen 45B/C as often as 9845B/C. Apparantly, 45B/C was used more frequently in the later years. @Francois: I currently have no

Quite interesting, it differs slightly from the (also April 1981) edition I have (see attached sample). -Ansgar

Maybe someone has misunderstood the term of the "last mile" 8-) It, however, would not be completely unusual for standardization to decide for a common item (such as a tenth of a mile) which lies near

The analyzer functions of the NI GPIB+ series are nice, however not required for instrument control or for HPDrive. With the analyzer you may listen on the HP-IB bus and track ongoing activity, either

Nice finding. The pics however suggest it is NOT a PCI-GPIB+ card with analyzer functions, but rather a plain PCI-GPIB card. Which of course works nicely with HPDrive and is a good value. I am not sur

Oh yes. I just four hours ago tried to win a CBM 9090 7.5MB IEEE488 hard disk at e*y, all lights on green (seller didn't know whether it works and even whether it is complete, no further information,

Well, you can plug in the Commodore drives, but there is no integration into the 200/300 series operating system (the CBM drives would need a dedicated driver). So you may talk to the Commodore drives

I assume that because the 385 was the last 'pure' series 300 member of the 300 family (the 382 already moved a bit more towards the later idea of a desktop workstation, i.e. 710, 715 etc.) it has been

Guess this is a decision no one can make for you :-) For normally I guess function goes over performance... I mean... talking about performance of systems from the 80s, what are we talking about? But

Yes, dd'ing from the hpi image to the SCSI disk device file would technically work, but I'd recommend to rather do a clean install and add the GNU tools afterwards. I assume HP-UX is dealing with some

Just for info: Most HP mass storage drives have implemented an internal loopback mechanism for channel diagnostics, which simply returns the bulk data sent to the drive back to the controller without

Virtual Machines implement an abstract model of a common hardware. This includes i.e. common graphics cards. In Addition, VMs usually try to pass through at least some standard interfaces such as USB

Might be a start. So yes, interested! -Ansgar
