There is a Write Line Model 2600 IBM Card Punch on eBay (#370060251979). I
know the seller (Weirdstuff Warehouse) - and took a look at it.
It is in good shape - the escapement works fine and the keys don't stick. One
of the folks at Weirdstuff punched blank IBM cards I gave him (which is what
you see in the eBay pictures). I would bid on this item myself - but I've
managed to "avoid" card reader and punch I/O ;-)
This is not my item (i.e., consignment) - nor do I have any business interest
in this auction.
Regards,
Lyle

Has anyone seen a replacement part for the older F8 series of
Fairchild/Mostek 3850/3851 etc. components? Or possibly the Mostek 3870
single chip CPU replacement? I have an application that needs a few of
these replaced...

I know this is probably the wrong place to ask, but I'll claim sunos is
vintage, or at least classic :-)
Anyone know anything about old sunos sources, like sunos 2.0, or 4.1?
Since solaris is now more "open", I wondered if sunos might also be.
I keep fiddling with booting sunos 2.0 on the sun2 emulator. It's close
- I got a banner at one point but still won't go. I'd love to look at
the code where it probes the multibus...

Dave,
I did purchase your kit and am using your asm85 (I do have a couple of
questions but it can wait), many thanks for having these available.
Most of the BASIC source I have found is either poorly written or so tightly
wound into a specific hardware implementation that it isn't really usable.
I did recently find something called BASIC-5.ASM, written by a Kevin Jordon
and modified by a Jeff Zurkow. It looks to be the Processor Tech 5K BASIC
adapted for CPM. It looks like I can pretty easily stub the CPM calls and
replace them with the IO routines I have created.
For anyone interested or anyone who has an IMSAI 8080 with a basic rs232 IO
system, I have modified SCS1 (the Imsai monitor) to be a bit more robust as
a debugger and to include an Intel HEX loader and Cromemco ByteSaverII prom
programming system. I also have the BASIC5K source which appears to be
pretty clean and well documented. I haven't found a lick of self-modifing
code in it!
I am more than happy to make these sources available.

Okay, so I saw this today:
http://www.youtube.com/watch?v=X4SCSGRVAQE
It's a video of a floppy disk drive playing music by screwing with the
stepper motor. It is my understanding that the video was a hardware
hack, but it got me thinking... For those who know floppy drives well,
do you think such a thing could be possible via IBM PC floppy controller
software calls only? Or is a hardware hack required to generate the
right frequencies?

You may want to check the service manual for the HP-85
http://www.series80.org/PDFs/HP85-RepairCourse.pdf
(username: pdf, passwd: iamhuman)
There is also a service manual for the HP-85 at:
http://hpmuseum.net/document.php?hwfile=3256
but it assumes that you have the self test ROM.
Now back you the SELF TEST error. This can be caused by many things (e.g.
RAM problem), but it may be due to the configuration of the machine.
Do you have any accessories connected to your HP-85? In particular I
believe that if you have the HP-IB interface and the Mass Storage ROM,
you may get a SELF TEST error in some cases (I am intentionally vague
because I don't have an HP-85 near me to check).
Try removing all cards from the back of the computer and power it on to
see if you still get the error.

I have my Imsai 8080 fully running and communicating with my Mac Pro as a
dumb terminal. Many thanks to this group for helpful pushing along the way.
I have also modified SCS1, the Imsai monitor program, to my liking and have
it burned into PROM. Since I do not yet have a floppy system for this
antique, I wrote an Intel hex format loader and just send the hex files over
the serial line to load them.
Life is good.
What I am looking for now is the 8080 asm source code to a good 8K basic
interpreter. I found one called TinyBasic but it was so concerned with
space the author built in a ton of self-modifying code and trying to follow
the logic is like untying a plate of spaghetti. I have another one called
BASIC85 which is better but assumes a VIO memory-addressable video system.
If necessary I will take this one apart and make it work. I hear a lot
about Imsai having an 8K basic, and I can find the manuals, but I can?t seem
to locate the actual 8080 source.
Anyone out there know of or have the asm source code to a basic interpreter
or know what became of the Imsai Basic8K?

Hi Jim, and thanks! The story is close enough for gummint work.
The New VS, also called the VS22000 family, is running happily at about 60
sites in 10 countries, and steadily growing. It usually runs in the Dell
PowerEdge 2900, although it can also run in the smaller 2950 and even the
1950. The high end is exactly twice the peformance of the top-of-the-line
legacy VS18950, and on the newer PowerEdge 29xx III, 220% of the fastest
legacy performance.
The current VS OS, 7.54.12, handles up to 1,000 devices/users, and the soon to
be released 7.54.20 will handle up to 2,000. Current virtual VS disk sizes
supported range up to and including 34 GB. In the VS world, where the first
VS supported 32 users in 512 KB (yes, KB) of memory, a 34 GB drive is huge.
We virtualized not only the VS machine but the principal I/O Coprocessors as
well -- SCSI, of course, Resource Sharing Facility (RSF), the VS clustering
technology, the "serial" IOC that used to handle coax/twisted-pair
workstations and printers, now providing TCP connections to virtualized
workstations, telecommunications, virtual Printer Interface Box and other
devices. We even built a PCI Universal Serial IOC to actually run legacy Wang
coax, twisted pair and fiber links. The latest virtualizations have been a
virtual device that provides high-capacity pipes to and from Linux, such as
for access to an Oracle database, and an Integrated Virtual Tape, which allows
the VS to seamlessy work with image files of tapes instead of physical tapes.
Our goal from the beginning was to make the New VS 100% seamlessly compatible
with the legacy VS for all VS software from the OS to languages to utilities
and applications. We have done that. A New VS is loaded from legacy VS
backup tapes or disk drives. No program or data conversion is needed. The
New VS runs the unmodified VS Operating System and all other VS software.
And yes, we signed a multiyear contract with Getronics (the succesor to Wang)
in early 2005 to work together to bring the new generation of Wang VS to
market. So it's all legal. Both Getronics and we sell the New VS worldwide.
Your correspondent wrote that the VS appears to have been a pretty fair
midrange system. It was and continues to be much more than that: The VS is
the easiest and most efficient mainframe to program, operate and use that has
ever existed. It supports about a dozen languages and is now in its 31st
year, with full object code compatibility throughout, something I don't think
any other computer company has ever achieved.
And, yes, it is a mainframe, distinguished by all the same characteristics
that caused the term to be coined to describe the IBM 360 -- decimal
arithmetic at the machine level, an instruction set that makes COBOL almost an
assembler for the machine, intelligent I/O "channels", huge connectivity for
block-mode workstations, disk drives, tape drives, printers and
telecommunications devices. The VS has an instruction set and memory
architecture almost identical to the IBM 370.

Before you start tracing things out, you might want to track down
the actual USER manual for the LA100.
(It's not on Manx or Bitsavers)
As far as I know, the LA100 logic circuitry performs a
SELF TEST on power-up, and will illuminate various LED's
above the keyboard, depending on the problem found.
The user manual may tell you what the various lights
are trying to tell you. (Paper jam, etc)
