It's mostly covered in the data books and app notes.
The last version was PALASM 4 V1.5.
If you google for "PALASM 4 Ver 1.5 software manual"
you'll find the docs on it.
http://jason.sdsu.edu/minc/pls_man/e_palasm.pdf
looks reasonable as well.
PALASM is REALLY dumb. It essentially works at the fuse level.
Hi,
I am interested in PAL / GAL programming and would like to buy a book on the
subject. Does anyone have any recommendation(s)? Alternatively, there may
be websites with PAL / GAL programming how to guides. Those would be useful
too. I have a rough idea using PALASM but it has been a long time since I
have used anything like it.
The reason is as my neo vintage SBC design is nearing completion and I will
be ordering the PCBs soon, however, I am keeping an eye out to the next
version. I am severely space limited with the Eurocard format (160x100mm)
and I am investigating potential PAL/GAL implementation to free some board
space.
Any help is much appreciated. Thanks in advance.

All,
I have all the pieces here to setup a Xerox 820 board with my Corvus
flat-cable drive except for the driver software. Does anyone have this or
have a notion of who might have it?
The interface box is rarer than hen's teeth, but I've come up with two of
them.

Are cordless phones truely full-duplex, or are they more like
loudspeaking phones whee a local voice input disables the speaker output?
That is not a problem for voice, of course, but it is for full-duplex modems.

Actually I have 3 of them. One is the 16 port model (with 16 RS232
ports), the others are the fixed-configuration 6 RS232/4 Centronics models.
But they do not solce the cabling problem. Nor do they have enough ports
for all my classics...

Well, that gives you 25 ports; how many more do ya need? At one point we
had 4 computer ports feeding more than 200 terminals over a single connection.
Alternately, it would be trivial to build a remotely controlled one-to-many port
selector out of relays or solid state parts, and you could use the NetCommander
just for the units that need baud rate conversion.
Of course the NCs don't solve the cabling problem, that's why I mentioned the
cordless phone. But unless you want to manually plug the desired system in
every time or buy/make separate connecting links for every system, you'd
need some way of concentrating the systems into one connecting link.
Obviously not a solution you'd approve of, but two old laptops with RS-232
and wireless cards would easily solve the connection problem. Of course
we usually prefer lengthy discussions here instead of simple solutions...

Out of curiosity, I went to torrentz.com and searched on "datasheet".
A couple of hits. One is a collection of datahseets from Elektor
that I haven't looked at (I'm on the wrong side of the pond to know
much about Elektor). About 230MB worth.
The other is a melange of various datasheets. Lots of op-amps, some
digital ICs, transistors and other bits and pieces. Rev. C of the
Kaypro service manual (Bitsavers has Rev. E). Information on a
Techtran diskette drive unit, some stuff on time standards. The gem,
IMOHO, is a two-file collection of Western Electric datasheets for
transistors, ICs, diodes and LEDs. Most look to be from about 1976
or earlier. It might be very useful to someone who needs to know,
for example, that the 18 pin DIP 146D is an integrated wait state
generator for the Bellmac-8 processor.
Unfortunately, these PDFs aren't indexed beyond general categories,
just sort of mixed all together.
Cheers,
Chuck

There were adaptors for external monitors. The one I had was "Exmon" brand.

Hi,
For the video pinouts, take a look at http://www.classiccmp.org/pipermail/cctalk/2001-July/176233.html.
To repeat part of that thread, the signals come from the bottom of the edge connector on the front panel and the shunt carries them to the top, where they go to a single inline connector that connects to the monitor. Looking at the edge connector from the front (numbered right to left, odd on top, even on the bottom), the signals are:
2 Ground
4 Brightness High
6 Brightness Low
8 Brightness Arm
10 Ground
12 Horizontal sync
14 +12V
16 Video out
18 Vertical sync
20 Ground
The shunt just connects the top contact to its mate on the bottom: 1 to 2, 3
to 4, etc.
There is/was a pdf of the Osborne 1 Technical Reference manual online. I don't have a link handy, but it has been posted before, so just search the archives.

I do, but my Ampex drives use analogue tape type spools rather than
the later 'industry standard' ones. They are half inch but ten track
not 7 or 9 and because of the smaller hole, with normal thickness
tape they got 3200 feet on a spool rather than 2400 feet. The machine
optionally used one inch or quarter inch analogue spools on different
decks, and the one inch transports ran at 150 inches per second.

Hi, just read your message about the Displaywriter. What I did to
exchange files was to send the information via modem on my Displaywtier
to my laptop's modem. It worked extremely well. Or I uploaded files to
Compuserve and then downloaded them. I would love to own Displaywriter
again.
