Coco3 and KVM switch

Hi, 
what is the easiest way to share a PC's keyboard with a Coco3 ?  
The video switching works fine already.

Re: 2MB CoCo3 expansion board "bounty"

Hi Everyone!
I have already created Tony Distefano's original 2MB Memory Upgrade design in Eagle Professional a while
back, but I never have had the funds to make prototype PCBs at OSHPark and see if it will actually work.  I am
using 30-pin SIMMS in this design instead of ICs.  I just quickly checked for the files and I still have them
ready to go.  I'll need to take a little time to make sure the schematic and layout is correct, but it is
basically all entered into Eagle Pro 6.6.0.  I'd like to get another Coco familiar electronics engineer in
on this project to help me make sure the design is sound.  Is there anyone who would like to assist me in this endeavor?
On a side note, I'm currently still trying to figure out why my 512KB Static Memory Upgrade PCB does not work
yet.  I could use a Coco familiar electronics engineer on this one too.  Thanks in advance for any help on
these and other projects.  Take care my friends.

Maybe the 2MB board is a good item for our first "bounty."

If you guys aren't familiar with the concept, other platforms use/have used it.
They set up a "bounty fund" that people interested pitch into, and whoever does it and completes it, gets the
bounty fund.

Now, this bounty fund is for the engineering/development - when it's ready, then all have to buy it.

Engineering/designing/layout take time, and the bounty encourages that.

When ready, setup the PCBs for manufacture with say OSHpark or whoever, and everyone goes to town.

Who's interested, and has the experience, capability, and time?
Anyone got a 2MB board they can loan to this person for reverse-engineering?

2MB board is definitely something I'd like 1-2 of...

Cheers!

Tony

Off-Topic, but advice

I had a delay in paying Tim for the CoCoSDC cases, and for good reason...

PSA...
If you folks have NOT put extra security on your bank and credit card accounts, DO SO!

Someone was able to call into my bank, give my name, address, and social, and change the address on the
account, and order new checks and ATM/debit cards.

*** now, WTF bank would actually DO that without alarm bells going off, is beyond me ***

Most banks have an option where you can put a master password on the account(s), and if this is not given, they
send the caller to the branch.

In this day and age, where ID theft is really not that difficult, PLEASE do so...
Also check your credit at the three bureaus, you can stagger and do one every 4 mos, as they all allow one per
year, and most stuff is the same.

/End of PSA

Does anyone have a Level3 disk that actually boots?

If anyone has a Level3 disk that actually boots, would you please send my self 
and Gene Keskett a copy by email. We have been trying to see why the code in the 
NtirOS-9 repository for Level3 does not work. The job is next to impossible and 
comparison with a working copy may be our only hope.

Thanks.

Robert

MULTIPACK COCO3

Hi coco addicts,

I found a schematic of a MULTIPACK in the coco archive, but I am not sure if it is specific for coco I, II or
III. Can someone tell me if it is suitable for coco III and if not, lead me to the schematic for the coco III
MULTIPACK + Pal chip hexfile

I understand that there where empty sockets on the IDE controller from the glenside computer club, are they
meant to be cartridgeslots, and then actually replace the MultiPack?

Thanks for answers

rgb2vga alive!

I'm very pleased to announce that I apparently have the first operational 
rgb2vga adapter outside of Luis's workshop!  The boards arrived from OSH 
Park earlier this week and I built one this morning.  About 1/2 hour ago, 
I was able to fire it up with my Coco3 and things look great.

There may be some tweaking necessary to shift the display to the left on 
my monitor, but that's probably a simple thing to do for a man of Luis's 
talents :-).

Next up, Apple 2, for which absolutely no VGA converter solution has ever 
come close to being viewable...

Help loading cassette data on a CoCo 2

Hi,

So I have a .cas file and have used xroar to convert it to a .wav using
the instructions at

http://comments.gmane.org/gmane.comp.hardware.tandy.coco/75033

xroar -load Pooyan.cas -tape-rewrite -tape-write Pooyan.wav
(then type CLOADM in the emulator, the WAV file will be written as it
loads the CAS file)

I put the WAV file on my phone, typed CLOADM on the CoCo, and started
playback with the black connector in the phone's headset jack.

I seemed to find the right volume range, but had trouble -

When I type CLOADM, an S appears in the upper-left corner.

At a certain volume, when I start playback, the S turns black but it
stays that way and never loads the file.

At a slightly different volume, the S turns black, but then after a few
seconds, I get an I/O error.

At all other volumes, the S never turns black.

Thoughts?

John

Help reviving an old CoCo 2

Hi folks,

Back when I was a kid, my parents got me a 64K CoCo 2.  They got wind of
my project to load the data off it, and gave the whole thing to me.  So
now I am wanting to make it work for my children!

I have two main problems.

#1 - the disk controller cartridge isn't working.  When I put the disk
controller cartridge into the machine, when I turn it on, it just has a
display with a bunch of artifacts.  The computer works fine when I start
it without any program cartridge in it.  I also have a baseball and a
music synthesizer add-on cartridge, and they are working fine.  So the
problem doesn't seem to be with the CoCo, but with the controller cartridge.

The silver contacts on it seemed to be rather dirty/degraded, so I took
the cartridge apart and tried to scrub them.  No dice.  Any ideas how I
might fix this?  Or where might I get a replacement cartridge?

#2 - the video quality is low.  I would call it noisy.  I remember it
being this way when I was a kid, but I always assumed it was due to the
marginal state of the TV it was hooked up to.  Obviously that's not the
case now.  I have it set to channel 4, and I have a screw-down to
coaxial adapter to hook it up to a fairly decent TV.  (It's a 13"
Trinitron.  Not a modern LCD, but I already had it, and I know it has a
much cleaner picture than what it's showing.)  Any ideas what I might do
to fix this?

Occasionally, the TV seems to somehow lose sync, and the display goes to
a very staticky black-and-white.  Turning the TV off and on fixes it.
