I'm trying to modify my 88-ACR to work with the KCS specification.
Does anyone know where the information on modifying the 88-ACR to
read/wrote KCS audio is?
Also, I was wondering if anyone ever looked at this card? The XR210 chip
MITS used for demodulation of the FSK signal is capable of MODULATING
too. (with both mark and space frequencies). Does anyone know why they
would have used 5 ICs and a few opamps to do the modulation when they could
have used the other half of a chip already present?

Hi,
Does anyone know a way of listing the files of a diskette or a disk drive of a System 34 ? I tried the following SSP commands (normally used on S/36 computer), but it doesn't seem to work ...
//LOAD $LABEL
//RUN
//DISPLAY LABEL-ALL,UNIT-F1
//END
After typing these commands, I was expecting something should appear on the CRT but nothing arrived, neither a list of files, nor an error message, even if I had to wait few seconds before the computer returns me the hand...
I don't really understand what they mean by the verb DISPLAY in the OCL statement guide. Does it mean DISPLAY on the CRT ? DISPLAY on the PRINTER ? DISPLAY in a file ?... grrrr....
Merry X-mas to all, and thank you for your help.
Fred.
I hope everyone has a very Merry Christmas today!

Hello,
I'm looking for the HP 10342B files to use it on a HP 1652B Analyzer. I did
find the documentation online - thanks to bitsavers.org - but am still
looking for the software. Is there a place I could obtain the files
required?
Kind regards,
Maurice
Out of interest, which is the correct terminology when defining a single point
on a disk's surface - is it better to talk in terms of cylinders, or tracks?
People often seem to talk about floppy drives in terms of tracks, heads and
sectors (e.g. for an 80 cylinder floppy with two sides they'll still talk in
terms of tracks 1-80 in conjunction with a side number, even though the media
has 160 tracks in total)
Talking in terms of cylinders seems to be generally the norm with hard disks
though, and perhaps seems a bit more sensible - but remember that hard disk
manufacturers are the people who introduced decimal megabytes into common use :-)
Personally I prefer to talk in terms of 'surface number' rather than 'head
number', as a given surface could conceivably have more than one head in order
to improve media latency - but I'm unsure as to whether to use
cylinder/surface/sector or track/surface/sector. It's all just semantics, but
for the stuff I'm currently working on I'd rather go with the 'correct'
version even if that happens not to be the one most commonly used...
cheers

Oh Man,
it's been years but,
check out the "listlibr" (list library) command.
i think it works with floppys but it may be a hard
drive command.
something like //listlibr dir
the dir switch need to be in there somewhere.
also i think display is the ocl command for display.
the listlibr command uses a switch for the crt or
printer too.
keep in mind that the crt only displays so many
columns
you'll have to send the output to the line printer or
a printer on the twinax to view the entire line.

I have available, for PICKUP ONLY in Kent, Washington (about 30 miles southeast of Seattle), a nice HP DraftMaster pen plotter, a couple of packs of paper (sizes C and D), and a boxful of pens.
This needs to be MOVED! I need the space far more than I need a plotter.
If no one claims it, I will have to dispose of it as best I can, even if this means tearing it apart and recycling its guts. I know that sounds harsh, but I've seriously reached the point to where this unit has to go.
Please get back to me by E-mail ASAP. If E-mail should bounce, please call me on (253) 639-2996.
This is the LAST time I'll be offering this. I need to hear from whoever wants it in the next day or so, or it's gone.
Thanks much.

"If Salvador Dali had owned a computer, would it have been equipped with surreal ports?"
I have a 16-bit ISA card labelled "Arnet 30500404 Copyright 1993 Arnet
Corp. Made in USA". It has 2 HD-15 female connectors labelled Line1 and
Line2, a bunch of discrete logic, 6 PALs and a Hitachi HD64570CP 2-port
Serial Communications Adapter chip.
A google search tells me only that it might have been an S/570 adapter,
but I have no idea what S/570 was (the most common hit seems to be for a
scanning electron microscope?) and if I can trust the one parts dealer
that seems to have one to know what it actually is :-)
Anyone know what this board does? Anyone want it?

>3) A 1970s era microcomputer controlling an analog synthesizer.
I have source code and custom interface cards from ARP's project to create
the first consumer computer controlled synth. The prototype was built out
of an Altair 8800. Never finished, never released. It was a top secret
project within the company
I will try to scan the entire binder and recover all of the source code off
of the 8" disks if it will help your project. Currently I think I am the
only person who still has a copy of this information. I got it by accident
when I bought ARP's Altair. ;) The binder has been sitting between the
two front seats of my car since September. I'll have a good excuse to scan
it on the 26th. ; ) This information has been left out of the history books!
I'll include a few routines below... NOTE, I tried to recover the
assembler written in "Altair Basic", but it is corrupted on the disk. The
assembler program appears to have been written in Altair Basic with line
numbers and then assembled by a special program. I would appreciate ANY
information on this basic assembler!
The person who wrote the routines below wrote a thesis at MIT in 1971 about
the possibility of a computer-controlled synth. He was using a PDP-15 at
the time.
I can provide more information, but a good quote about the Altair 8800
Synth "One of my more impressive demos was doing four-part harmony using a
woodwind ensemble (flute, oboe, clarinet and bassoon or French
horn). Using the pro-soloists on the four-channel Bose system in the small
lab sounded very grand. In fact, the lab was under tight security and not
ever the VP of marketing was allowed in, though he tried. (We wanted them
to sell what they had now, not get musicians waiting for things to come.) "
