Help with I-Code

As some of you know, I have been working on a Basic09 I-Code
disassembler/decompiler/unpacker. While I have had to take time away, I
find now that I can spend a little time on it. I have been thinking about
the problem with TYPE statement data in Basic09 I-Code modules. I think I
can get more information by creating a few test modules that contain
various TYPE statements and keep track of the similarities/differences
between like statements in differing procedures. Hopefully that will reveal
more about how to interpret the data in the modules.

I will likely need help with the testing, since I cannot at this time run
my version of MESS to do the testing with. What I would like to do is work
with a couple of people who can do the packing of the modules and dumping
the I-Code contents to a file to send back to me to unravel. I will be
writing the test procedures blind (from memory and without knowing if I
have made a mistake or not), so some debugging may be required. In those
cases, I will need a listing of the source with corrections. Are there any
takers here? Anyone interested in helping out can email me.

Wayne

64k memory check


Hi guys,
I just aquired a Coco 1 (grey) Cat 278-300A., CCR-81 Cassette Recorder, X-Pad and a few carts and tapes.
The Coco powers up fine.
Extendended Color Basic 1.0
PRINTMEM reports 24871
Since this is an "F" board and the "F" boards were the first Coco 1s actually "meant" to be upgraded to 64k, I
assume it is 64k.
The warrenty seal has been removed and replaced by a Radio Shack Service Center seal, so I would think it had
to be upgraded by Radio Shack or the seal would be broken. What I would like to know, and I know it's been
discussed many times before, is if there is a PEEK/POKE or short routine to test for 64k? I plan to hook it up
to a drive and run OS-9 Level 1 and that will surely fail if it's 32k. But if there's a quick way, that would
save me a lot of trouble

Here a link to some pics of the Coco 1 and accessories I recieved

Extended color basic to Color basic on COCO 2

Okay so my uncle gave me a COCO 2 computer, he had no idea if it worked or 
not, when i turned it on it worked, i noticed there was some commands written 
on the machine, like sound, the strange thing is that when i turned it on then 
it said Extended Color Basic, not sure which version, it also said Copyright 
Microsoft, if it said anything else i do not remember, and when i used the 
sound command it played beeps based on the DURATION and FREQUENCY i specified, 
then a few days later when i turned it on it now says Color Basic 1.2 (C) 1982 
TANDY and sound no longer works.

Re: Hardware sale- shipping

Roni,
Sent a e-mail on shipping rates (which are insane) let me know and I will send a Paypal invoice if you want it.
Remember these are NTSC machines running on 120 power (standard for USA and Canada) - I am not sure
what Portugal takes for power/ Video, but I seem to always have to remind the Amiga guys because they
just assume its PAL and European standards and then are choked because it won't work properly in their region.

Hardware Sale

My hardware sale on friday went so well, that I am spending the day doing the boxing and shipping from it. I
have also decided to do another sale today on the hardware for those that missed it and wanted to get in on
today's (well actually tomorrow's-because of the holiday) mail run. All hardware prices have been
reduced between $5 and $50 and everything is under $60 -INCLUDING shipping to the USA and Canada. This ends
at midnight (MNT) tonight

Simple Coco bus buffer for HW folks

[ I tried sending this before, but I think from the wrong account. Sorry 
if this is a dup. ]

I put together a little board to help me with my hardware development, 
and I thought that it might help others as well.  It's essentially a 
stripped down version of my ROM/device emulator - just the buffer chips 
and a pin header breaking out all of the needed stuff.  The header is 
compatible with the GPIO header for the Terasic DE1 FPGA dev board, but 
obviously it can be used with anything, both 3.3v and 5v, provided that 
it can supply the board with 3.3v.

Take a look at the video to see a quick demo using the FPGA as a ROM: 
http://www.youtube.com/watch?v=ttf82tPXUko. Overkill, but you get the idea.

When I have a few minutes I'm going to put the board layout and 
schematic up on the web.  I also intend to sell populated board for 
those of you who don't like to do fine pitch SMD soldering.  Haven't 
finalized a price yet, but I believe it will be around $35.  If you're 
interested, send me a note.

I'm still working on the ROM board, but I'm playing around with some 
options to make it cheaper and more flexible.
   -Matt

RGB2VGA in FPGA, useful?

Could this be useful in a "v2" of Roy's adapter?

This RGB to VGA adapter was designed upon an Altera FPGA for use with a BBC
Micro (PAL) and has been released as open source.

https://github.com/makestuff/rgb2vga

>From the "ReadMe"...

NATIVE DIGITAL RGB TO VGA CONVERTER

This code accepts a pixel clock, R, G, B, HS and VS from an old computer
and generates a VGA signal suitable for display on a modern monitor. The
main caveat is that monitors to be used with PAL machines must be able to
deal with a 50.000Hz vsync (many do, some do not).

<...>

This will build a .svf file suitable for loading into an Altera EP2C5 FPGA
(e.g http://www.ebay.co.uk/itm/150835820710). Suitable level-shifting is
required to protect the FPGA from any 5V signals. On the VGA side, a series
270R resistor on the R, G & B lines is all that's needed.

toolshed updates and PPA

Hi everybody,

I am new on the list, although I have been peeking at the archives for
some months already. I am a Dragon 32 user and have recently picked up
some development after a few decades' long hiatus.

= m6809 dev PPA =

For those on Debian-based systems, you may find my m6809 PPA (personal
package archive) convenient.  It has the latest versions (or
snapshots) of toolshed, lwtools and xroar. The packages are built on
Ubuntu 10.04 which means they should install without problems on any
Debian-derivative released in the last 3 years. The PPA page itself
has instructions on how to add the PPA to your software sources so
that you get automatic updates.

        https://launchpad.net/~tormodvolden/+archive/m6809

= toolshed updates =

For those unfortunate Windows users, you can now find updated build
instructions in the toolshed mercurial repository. Building should be
straight forward on MingW systems, and I would welcome feedback on
Cygwin systems.

A little hint for anyone bandwidth-challenged: The above PPA contains
a 1.1 MB orig.tar.gz which is a source snapshot without the 40 MB
documentation and the overhead of a hg clone.

makewav has received some updates, and can now read DECB headers, and

User Group and Collections VHD


Hi Guys,
I finally finished the "User Group and Individual Collections OS9.vhd"
Each collection is in it's own directory and each file archive is uncompressed to it's own directory
The archive includes (OS9) OCN, Princeton, RTSI, CIS-OS9, and The Color Computer Disk Image Archive.
These are all OS9 archives and searchable with any OS9 search utility. Stick this vhd into drivewire and
have access to one of the largest single disk, uncompressed archive collections on the internet.
It has taken me about 3 months of decompressing all the files from each archive and moving to proper directories.
The one thing I didn't do, is set all the attributes. As most any OS-9 user knows, when you decompress a file,
it's attributes are not set. So you will have to do this when you want to use a file.
Here's the link:

https://dl.dropboxusercontent.com/u/23059963/Stuff/User%20Group%20and%20Individual%20Collections%20OS9.vhd

It will also be available from my website under the utilities page.
This vhd rplaces the previous RTSI vhd I had up before as RTSI is included here.
If the link doesn't work, try again later as it may still be uploading

Enjoy :-)
