I wonder if anyone has the boot disk for this system?
I have them buried and can't find them and need to boot
the system for a project sooner than I'll find them.
Thanks
Jim
If anyone within striking distance of Birmingham (UK) wants an AS/400, I've
got one which you can have for the cost of coming over and taking it away
(strictly pick-up only, it's far too bulky to post).
I believe it's a model 9404, with an expansion cabinet - each cabinet is
similar in size to a DEC BA123 cabinet, IE not massive, but big enough....
And that's all I know about it, I've never even plugged it in!
Contact me off list if interested. Thanks.
Alternatively, does anyone have an address/phone number of a UK based IBM
dealer/scrapper who'd come and haul this machine away (there's currently a
skip located two houses down from where I live, I'm resisting the temptation
for now....)?
TTFN - Pete.

Wow, Rob. That would be fantastic. Thank you. Please let me know
if there are any expenses related to duplication for which I can
reimburse you.

You are correct and I have that. But thank you, because I might not
have been aware of it. You had no way of knowing.
I also have "Guide to the Macintosh Family Hardware", and the Inside
Macintosh series. If I was an experienced video card designer, that
is all that I would need. They explain the interfaces, more or less.
But I would also like some materials that would teach me something
about the art. For example, there are a number of different ways
to handle updating the frame buffer so that one avoids artifacts on
the display. What are the pros and cons of each and how do they
apply in this particular situation?
I could try to build cards for each of them and test it out. But I
probably can't afford that many proto-types. On the other hand, I
might be able to get several designs out of one or two prototypes by
making good use of the flexibility of FPGAs.
Still, I'd love to read about some designs that worked and see what
choices other folks made.

Cool. Thank you for the ideas. I will look at those commands and
develop ideas on trapping and accelerating them.

Lookup ALPACA on Yahoo groups.com. There are several Z80 systems on the net.

All:
I just got a complete working Hawthorne Technologies 68000-based SBC.
It?s a 5.25? form factor computer based on the 68000 CPU. It has two serial
ports in addition to a floppy controller which is PC-compatible - it uses
360k diskettes and PC drives and the disks can be read-written on a PC.
Among the disks provided was an editor, debugger, assembler, and Forth.
What it doesn?t have (that I can see) is a C-compiler. Does anyone have this
SBC with a C-compiler?
BTW, I made disk images so if anyone needs them, I got ?em.
TIA.

Hello all,
Just been sorting through all my junk as part of a spring clean.
One ?sort of on-topic? item that seemed too good to throw away is a MIDIman
Winman 4x4 MIDI interface on an EISA card.
Pictured here (warning 4MP image):
http://ozpass.co.uk/files/Winman-4X4.jpg
The card offers 4 in/out MIDI channels and was pulled (a long time ago) from
a system running Cubase VST on Windows ?98. Functional to the best of my
knowledge.
If anybody wants the card it?s yours free-of-charge (excluding cost of
delivery).
Let me know off-list.
Regards,
Austin.
P.S. Based in Manchester, UK.
I'm building up a demo S100 system for VCF. I'm considering using a
modern switching power supply for regulated power and abandoning the
onboard voltage regulators on each card. I know the last CompuPro boxes
took this route so it must be feasible. What is the general
wisdom/experience with this approach?
Thanks!

I have been on this list for around 10 years and can say with pretty
fair certainty that the mix of posts has changed substantially during
that time. Jay, perhaps you don't notice this because the type of
things you're most interested in - old HP and DEC gear - are still
actively discussed. But discussions of the small stuff: 8-bit micros,
CP/M machines, Apple Lisa's, HP Series 80, etc., have all but
disappeared. There used to be a pretty active discussion about these
sort of machines on the list, and a lot of resources to draw on, but no
longer. Posts about those sorts of hardware are few and far between and
are, when they do occur, usually generate no threads.
As I previously said, that's an observation/conclusion, and other are
entitled to agree, disagree or vituperate, but I think it's backed by
empirical evidence. Some may not like the conclusion, or claim it's
incorrect, but this is something I've observed for at least a few years
and I have a lot of archived posts that seem to bear me out. I thought
it was pretty obvious that I was using an example - in this case the
relative response to the Linux post vs. the Kaypro post - as an example
of a general trend. Naturally, the naysayers, serial disagreers and
chronic debunkers conveniently ignore the obvious and pretend that I am
trying to draw a broad conclusion from a single occurrence, even though
they know (or damn well should know) that's not the case.
