CommodoreOne Overview
Here is a General Overview of the features of the Commodore One as of
1/21/2002. Some features may change slightly as development
progresses.
What it is:
The CommodoreOne computer is a 2002 enhanced adaptation of the
Commodore 64 - the most sold of any computer model (Guiness Book of
World Records). While retaining almost all of the original's
capabilities the CommodoreOne adds modern features, interfacing and
capabilities and fills a sorely needed gap in the hobbyist computer
market.
The estimated price will be only $200 USD.
(user will need to supply micro ATX style case, ATX power supply,
drive(s), PS/2 keyboard, mouse and SVGA capable monitor.)
Features/Product Description
Physical Appearance
As sold the CommodoreOne will be a motherboard ready to mount
into a Micro ATX style computer case. Ports will match the holes of
the case as well as additional port connectors will be included for
addition through punch-out ports on the case you pick.
Power
Connectors on the CommodoreOne will be ATX style. The
CommodoreOne board is designed for a 5vDC power source and
accommodations have been made to keep the machine as 'laptop/portable
capable' as possible.
note: ATX 'power down' can be controlled by software.
CPU/Speed
The main processor of the C1 is a (65c816 processor running
approximately at 20 MHz) the 65c816 is a 6502 compatible processor
with a 24 bit address range extra instructions that access the full
memory range are added to the 6502 core.
Software throttle for classic 64 speeds.
The system bus runs at 50Mghz, the 60 hz CIA clock of the
system is provided by internal circuitry.
Secondary 6502 processor for i/o support.
SuperVIC Video Capabilities
VGA monitor output
VIC-II compatible in all video modes 60hz/50hz emulation is
software selectable.
Classic Emulation & SuperVIC Mode is software selectable
Extended video modes as well as combination modes with
classic VIC-II modes are possible.
Memory addresses of features (character matrix, screen
memory, color RAM, etc.) are each 24 bit addressable (except for the
color palette which resides inside the chip's memory)
16MB video RAM with adjustable mirroring/or relocation from
CPU memory
Max Resolution 1280x1024 Sync settings from 60hz-? (depends
of resolution)
Maximum of 256 colors out of a palette of 65,535 in regular
and linear modes
a special 'Chunky' video mode with access to entire palette
(limitations apply)
Graphics modes include 64 style cell video and linear video
Hardware based line drawing/fill & pattern fills/overlay,
scaling?
Overscan
Windowing mode (view a portion of a 1280x1024 display on a
320x200 window & scroll)
Full byte Color RAM can be moved now!
Blitter functions (block image transfer) Logical operation
AND, OR, XOR
On-Board Copper Processor*
8 sprites
Can have up to 256x256 resolution
Can use classic linear or 64 video style graphics (pick up
screen image?)
Mouse controlled 'mouse sprite'
Based on a 320 dot clock (same pixel size/position on all
video modes)
MonsterSID Audio
Classic SID Emulation (including address mirroring)
Monster SID Mode
16 stereo SID voices (1-8 left, 9-16 right)
Sync and Ring Modulation and filtering on all voices
Extra voices mapped in order after the first three DMA audio
8 Stereo voices (4 left, 4 right)
64k internal sound memory (sound or instruments) as well as
access to main CPU memory for playing DMA clips.
Variable sample playback rate.
Audio resolution of 8 bits
DMA segment playback can be either continuous (loop) or
one-shot (note/segment)
Memory
Computer Memory (hard wired-on board) is expected to be 32
Megs of RAM, 16 of which is the main processor RAM and another 16 Megs
accessible by the Video Controller
64K RAM for Monster SID (DMA Audio or Instrument clips.)
The System will have a small 'boot ROM (8-16k) which will
handle power-on initialization
Main OS storage will be via a Compact Flash media interface
with card which is designed to hold the CommodoreOne's operating
system(s) as well as other data. There is not limit to card capacity
(current Flash Cards contain up to 512MB memory) Flash media is 'hot
swappable'
Internal I/O
3.5" floppy drive connector with 1581 emulation (using PC
drive) with 64k RAM capable** of supporting MFM 720/1.4/2.8 capacity
drives via software (WD1772 compatible)
IDE Interface with DMA support**
Compact Flash Media Slot (see 'Memory' above)
LCD Interface (TTL LCD style)Internal Expansion
3 Mini Zorro/Cartridge Slots
Up to three 'mini Zorro' style expansion bus connectors
-software selectable and configurable addressing
Compatibility with existing Commodore Cartridge bus at one
edge of the connector (connectors will be 'keyed' to help prevent mis-
alignment of cartridges.)
Other contacts will include added address bus, config dot
clock, video lines, etc.
Capability to configure C1 system chip settings externally
1 Basic PCI Expansion Slot - A basic 'Register access'
version of the PCI bus for connecting an Ethernet adapter or other
modern I/O device.
External Interfacing
PS/2 Keyboard port with either Commodore-64 matrix emulation
(configurable) or raw data access
Joystick lines can also be emulated via keyboard
PS/2 Mouse with 1351 emulation and bi-directional communication support.
IEC Serial Connector supporting Commodore VIC/64/264/128
drives and printers.
2 Joystick Ports (limited to joysticks and joystick
compatible devices only)
High speed RS-232 Serial Port (16550 emulation with 16? byte
I/O buffer)
Parallel port - (GEOCable compatible interfacing only) can
double as PA0-7.
Geek Port ('Whatever spare lines are left... around 24 I/O
lines)
* About the Copper
The Copper processor is designed to make adjustments to the video chip
'on the fly' as the video chip draws the screen the copper can be set
to activate at specific pixel locations - upon activation it can
modify the video registers with new values. This is how split screen,
layered screen and/or mixed video effects are so easy on the Amiga.
The Copper command list has three commands 'Wait for Raster Value',
'Skip Function if Event,' and 'Store Value to Register'.
** Floppy/IDE Interface
In the initial release these interfaces will not have any support
software (with the exception of 1581 emulation), it is hoped that with
the ease of interfacing to the floppy and IDE drives a more 'software
oriented individual' will develop the necessary support software for
these devices.

That's the first I hear about this; that's an awesome choice! BTW, I heard
there are 1GB compact flash cards out now. (!)

Depends on the color depth. From the posted spec, you get 16MB video RAM.
Personally, I'd much rather see 1280x960, which is a square pixel aspect
ratio (and a multiple of 640x480). 1280x1024 gives you wide pixels.

1280x1024x8Bit (Color) = 1280kB
In monochrome bitmapped mode 160kB would be enough, but I guess that's
not what you want.

Man! I really want one of these things. More than anything, I'd like to
get one to write demos on. I can't wait until they are ready to ship.
I'm definately buying one, and I hope everyone else that ever had a 64 does
too.
Wouldn't it be great if this machine rekindled the huge C= scene like we
had in the old days?

Did she say it was supposed to run on +- 5 VAC, or is it supposed to
run on +5 V DC power supply?
If the latter, I've already got a few. But... hmmmmm... Say, how many
1.5 vdc does it take, in various arrangements, to make a 5 vdc battery
to draw how much power from, to keep a Commodore One going? I mean,
supposing I had a big bucket full of AAA batteries, how would I put
them together to get +5 V dc, with enough power to keep the thing
from forgetting itself? Obviously not the bare minimum in series,
but there is going to have to be some of them in parallel, too. ;)
Aw, heck, probably better force myself to buy some kind of
uninterruptible power supply someday...

Well...yes, it would be great , but let's not drown in our dreams.
This is a HOBBY machine. Far from being a
well-lubricated-marketing-machine-seld-in-a-box.
How many kids out there would buy the motherboard just for the right
to solder, fix, glue and install all the hardware ? Most of the chance
are that their FATHERS would do it. Sure, I don't mind, coz it's a
HOBBY. But even for the casual gamer/programmer/whatever bozzo who
wants a decent machine...like...phaaa...no one has even started
programming for this baby. Wheels ? Metal Dust? sure. But when you buy
a new machine, you want it to have LOADS of software. Don't get me
wrong, I am thinking of buying this babe (I have no life) but , nahh,
except from a nice article on BYTE or Popular Sceince, I don't think
it would hit the street.
Come to think of, I don't think it was even made for
everybody....hmmm...

Well, looking at the C128 or the C65, the C64-demo-scene will
overcome the C1 also :-)
However, /me wants this beast, please keep me informed when it will
be sold.

That's only because Jeri Ellsworth hasn't published the memory map
yet. At the least, she has narrowed down the number of sprites it
will have - 8 - just like on the C-64. I'll bet her machine could
have supported lots more sprites, but for the problem of I/O ports
in the $d000 range that locate the X and Y axes for the sprites.
(If only she had a way of multiplexing the $d000-d03f range so we
could have multiple sets of 8 sprites on the screen at the same
time. I believe 8 sets of 8 sprites would have required as much
as $d000 to $d1ff to be mapped to her video board, just for the
board to know where to put them on the screen in terms of X and Y
locations? Did I add that up right? Anyway, so much that COULD
have been done with 256 sprites, each up to 256x256 pixels in
size. It might be a chore figuring out which sprites are in
contact with each other, though.)
|Wheels ? Metal Dust? sure. But when you buy a new machine, you want
|it to have LOADS of software.
When somebody gave me a $1,000 Compaq, all it had was Windows. Sort
of underpowered, all things considering. No programming utilities
whatsoever. My C-128 can outperform it, seeing as how stripped down
it is.

I can do more with a single Commodore One than I can with several dozen
Compaq computers.

In the short run, have you considered doing a 128 80 column game or
demo with
moving graphics and over 16 colours?
:>
John Elliott
And maybe using the 40 and 80 columnscreens simultaneously?

In 64 hi-res mode it would be
(1280/8)*1024... 16,3840 bytes for the bitmap
160*128... 20,480 bytes for each color card plane
so 204,440 bytes. ...4 64k blocks would do it, even enough to spare
for multi-color mode.
In Planar mode assuming 256 colors (1 byte) per pixel, 1,310,720
bytes... less than a 10th of video RAM.
I myself am thinking of just how cool it will be to make Commodore
character graphic games in a whopping 160x128 character display.

Since the C=1 motherboard is ATX form factor, I would assume that a standard
AT power supply would be exactly what you need. Consider a battery power
supply only if you want a laptop C=1. (a possibility...) :-)
>Aw, heck, probably better force myself to buy some kind of

A UPS is nice for _any_ computer. Not only does it give better spike
protection than cheap spike protectors, but provides power line droop
protection as well. Plus, it even protects against total failure of your
local power grid! (Don't be without one in California!)

In a 16 color mode (like the original C64) he might be able to get by with
512kb.

I agree. There will never be another "scene" that will match the C64 scene
back in "the day"... However, the C=1 should breath a few more years of
life into the current scene.

If I have everything straight, there won't be much (if any) soldering. Just
mount the motherboard in a standard ATX form factor case (most of which come
with a power supply and cooling fan). Then mount and plug in your hard
drive, SVGA monitor, and keyboard.
Presto! A C=1 computer!

It may not sell like the Palm Pilot, but with a C64 compatible mode at least
there is tons of software.

Maybe not everbody... but, as I think about it, I have an old 386 with a bad
motherboard just sitting in a closet. When I listen closely, on a quite
night, I think I can hear it begging to become a C=1!!
Burt
(product specification plus what they do)...
It seems like I suggested it before but.... sigh....
Until you tell people what the products will do you will never sell any
serious quantities and more importantly the financial backing will also
lack... 50% of anything is marketing.
That's all in my opinion of course..

You're right, it isn't. It's being made for people who remember 64s and
have some idea how a computer works, having learned on their original
Commodore.
If someone wants a computer made for everybody, they should buy an iMac.
This is a computer made for geek hobbiests, and Jeri knows that. That's
her market focus.

Aren't those kinds of cases free for the taking, in various big cities
where they end up in somebody's closet, or in a garbage heap somewhere?
As for handicapped individuals who just can't get outside to get a
case, there's bound to be someone around comp.sys.cbm who could mail
them a case for a nominal price.

Well... ATX is the CURRENT case for factor. AT is the OLDER (since 286)
form factor. since the board uses the microATX form factor, you can get
away with a mATX case as well as regular ATX. There are some pretty
miniscule mATX cases out there, so these IMHO would be the preferred
option. Any individual (handicapped, or just lazy like me) can call up a
local PC supplier and arrange to have an ATX case dropped off. A cheap one
should cost you around $30CAD.

A worst case scenario is accidentally buying too many of them, and

And yes, if you are lucky you might find a company about to throw an old

Perhaps she could drop by with her camera crew, and we could really
have a field day with these kinds of things? I've always wanted

I couldn't agree more, without ethernet it once again limits commodore
users to serial --> linux setups and so on, In this day and age
Ethernet is a necessity, and given that compact flash is supported on
ethernet shouldnt cause that much fuss, but then again im not the one
building it.
Six of DLoC
Feb 2002:
I'd love to, but I've only got two dead 128's, and the 128D I just bought
on EBay doesn't have a keyboard. :(
I did a page for Richard Bayliss's Joketro Compo, but didn't finish it in
time. It'd be nice to find a crew to join, or some independents who want
to do some NTSC stuff...

No... I dont think so... switching to a different platform kills the current

I'll still buy one.

Hi Daniel,
The reason I started the C=1 project was to create a c64 like system
that retained the same "feel" as the older units. When I say feel I
mean the overall simplicity and manageability that modern PC's don't
have anymore.
The CPU bus on the C=1 is totally decoupled from the graphics/sound
bus by a fifo like arrangement. This allows any type of CPU to be
installed as long as the fifo's are adjusted accordingly to the amount
data flow. The CPU can also be halted if the writes to shared memory
overflow the FIFO.
I'm planning on shipping the C=1 with a 65816 and a 6502 core at
first, but maybe in the future I or someone else can make a CPU card.

I wouldn't say the SCPU killed the scene -- certainly not in numbers since
SCPU usage is still a relatively small niche segment of users at large.
Also, I'm sure I'm not the only developer who insists that everything I
write be runnable on a stock 64. Obviously, I'll throw enhancements in for
the SCPU, but HyperLink, Mah-Gong Special Edition and Nether (when it's
finished), though they can take advantage of an SCPU for improved speed
and performance, will always boot on a stock system.

What is (will be) Nether?

IIRRC the C128 keyboard is identical to the C128D except the C128's is built
in the case.If you can find a connector to fit the keyboard port you could
probably hack one together.Heck,just run wires from one of the dead C128s
and you'd even have a case for the keyboard!

It's a Wolf3D-like shoot'em'up. There is a very old 1996 alpha there but I'm
proud to say that the primitive G-II build I have running on the Power Mac's
emulator already surpasses it in smoothness and speed (and more optimisations
can still be made). The graphics resolution is the same, however.

I personally wish there was more REU support. Those things aren't uncommon
and they're pretty easy to support in software. I do have a SCPU, but that
basically works with most app software with no modification. :)
