One finds the best stuff at thrift stores. Check out what I found today:
The Anatomy of the 1541 Disk Drive
By Abacus Software, 1984
ISBN: 0-916439-01-1
It contains a full description of the file system, the file structure, the
file commands, and also has a full 6502 assembler listing for the drive's
ROM! Very cool. This book apparently also came with a "Test/Demo" disk
but the programs are printed in the book so they can be duplicated. What
a treasure.

Anyone know where I can acquire an Intel i86 and/or i286 development set
with software (asm, link, etc) and docs? Used is fine, of course, but
the software must be intact.
Thanks,
Mike
(I'm in Utah, BTW if anyone has one close...)
Thanks...
I haven't got time to reply in detail, but be warned.
1. The IBM cards that went in the 3270PC range were _not_ the same as
those they sold as upgrades - the latter drove ordinary displays, etc.
2. There were many popular 3rd party 3270 (3278/3279) emulator cards
available, the best known being IRMA.

BTW I was wrong about the 5272 - it is 720 x 350 x 8 resolution.

I just happened to have my cards out for cleaning.
Yours seems a bit different. I wonder if it's earlier or an expansion
card for the pc/xt to give it 3270 comm capability.
My connection card has:
The BNC
2x8435
a BUNCH of gates or st, these 74L???
no memory that I can see (the computer has 640k)
a clock/crystal marked 14.1523 mhz (1589449)
Some IBM chips
2x 5617135
????
I dunno...

Okay, I'm working on the next batch of computers for my web pages, and am
looking for any anecdotes, links, resources, or specs relating to these
computers:
Compaq Portable 386
HP 75D
Iasis Computer-in-a-book (8080)
Panasonic Senior Partner
Amstrad PC-20
NEC Starlet
Panasonic HHC
Seequa Chameleon
Sharp PC-4
TI Compact Computer 40
Specifically, the data points I list in my specs table are:
{mfr}
{location}
{model}
{processor}
{speed}
{opsys}
{bits-int}
{bits-data}
{ram-min}
{ram-max}
{rom}
{input}
{display}
{stor-cas}
{stor-fdd}
{stor-hdd}
{ports-ser}
{ports-par}
{ports-kbd}
{ports-joy}
{ports-oth}
{expansion}
{intro}
{discon}
{cost}
{size}
{weight}
{power-volt}
{power-conn}
{power-polar}
{notes}
A lot of these I can pull from the machines themselves myself as I sit down
to do each one, and for some I have manuals, but I really appreciate any
info anyone can offer. Also, stories of your experiences buying one new,
or how you always wanted one, or rumours, or what have are definitely
welcome.
Thanks!

Not only Midi, but also great software and (Falcon (68030) and beyond) a
DSP port for right-out-of-the-box direct-to-disk digitial recording.
Cubase Audio (about $600 new, I think) gave you 16 channels of digital
recording. (included software wasn't serious and only gave you two
channels.) All you needed was a lot of diskspace and something to record.
When the Falcon came out, it was one of the only affordable D2D solutions
available. And now, with CD-Recorders running around left and right...

Thanks to all who responded to my earlier plea for info about some of the
computers I've got in my collection! I've got the pages up (and fixed the
"\" <> "/" problem) for a dozen or so computers. Anyway, any info,
comments, suggestions, criticism, flames, etc. always welcome.
The page is at <http://www.sinasohn.com/clascomp/> for them what's interested.

Hi!
I was just offered a Lisa 2/10, which I will happily accept. I do have
the 2/5 but the second would be nice, albiet a tad greedy. :) However he
wants me to name my own price, and said that it wasn't working.
Apparantly the self test and stuff works, but it doesn't boot up - I
assume this to be a problem with the hard drive, but imagine that it
could be something else. Does the 2/10 have the battery problem found on
the 2/5, and is this particular error the sort of thing that can be
repaired given that it does start? I had imagined that a serious error
would not allow it to start at all. :) If it can't be easily fixed I'll
probably buy it anyway, but I don't want to offer too much (as I have
almost no money) but I definitly want to save it.
Thanks heaps,
Adam.

Y'all are gonna make me pull aphasia out of storage and set it up
to look at the generic 4.1.1 config file for the Sun 3, aren't you?
My recollection is that this was changed about the time Sun started
shipping SPARC workstations that were likely to have internal disks.
(Or was it with the 3/80? That could also have internal disks.) I
first ran across it when I had to deal with SPARCstation IPCs and
found that the kernel config file mapped sd0 to SCSI ID 3 (and that
systems shipped with an internal disk tended to come with the internal
disk's SCSI ID set to 3).
My guess as to the reason for this was that a number of these systems
were displacing older Sun 3/50 and 3/60s with external shoeboxes,
where the disk in the shoebox was set to SCSI ID 0. The old Sun 3
would go away but its shoebox would stay behind, and the user would
get the bright idea to plug it into the new SPARCstation for a little
more disk space. The 0<->3 swap made this work a little bit more
smoothly by avoiding the need for the user to open up the shoebox and
switch the SCSI ID, as well as the service call required to explain
this need.

Given that this is a Sun 3, I would re-set them for disk ID = 0 and
tape ID = 4. At that point, you should be able to get to the monitor
prompt by pressing L1-A (hold L1, press A) while it's trying to boot
>from the network (or before) and typing "b sd(0,0,0)" to get it to
boot from disk, or "b st(0,0,0)" to get it to boot from tape. Oh yeah,
you need to press return after that ")", unless you want to pass some
arguments to the boot, in which case you should type them before you
press return (e.g. "b sd(0,0,0) -s" to boot single-user mode).
I don't recall exactly how to set the default boot device. Once you
have something bootable on the disk, you want to set the default
boot device to "sd(0,0,0)". This setting goes in the EEPROM, only
I don't remember exactly what locations to use. If you install
SunOS 4.1.1 there will be an "eeprom" command that will help you
to not remember too.

Does anyone have any portable computers that are 15lb or less that
they could give or sell to me? This includes Z88, Intel stuff, etc.
Not the Mac Portable, since I have that. Preferrably, I would like
something that could run without being plugged in (having replaced
the battery :). Anyone have an IBM Convertible?
