Re: In need of a 1987 GIME

When I reply to an Email in digest mode it gets sent to the individual and not the list. So, I am posting my reply
to Art again, for the list.

If anyone has a spare from a broken coco, or wants to trade for the 86 (I have a spare) please let me know.

Hi Art. I plugged in a coco3 with an 87 GIME and the games work fine. Iron 
Forest only registers shots to the center of the screen with an 86 GIME. 
Medieval Madness works but the aim is way off. Using a Machine with the 87 
and shots are dead on.

In need of a 1987 version GIME

Hello. I am in need of a working 1987 GIME chip for the coco3. If anyone has one that they would be willing to
sell me please email me.

chaspelosi at outlook dot com

My original coco3 I purchased when I was a kid has the 1986 version. I have a Diecom light gun adapter and I see
that the games made for it do not work properly with the 86 version.

Thank you!

Charlie

A question for all you hardware hackers out there...

I'm looking at continuing the development of a CoCo hardware project I started a
few years or so ago. The project is FPGA based and will use a medium density QFP
chip (284 pins). My question is; how do hobbyists manufacture low quantity PCB's
that have such a part or even BGA components? Soldering devices are just not
practical and there doesn't seem to be a viable remote carrier that I can find
that will allow the part to be installed on a PCB without it being installed by
a professional board house.

There's gotta be a better way. PLCC's were a good alternative but the densities
on current FPGA's are beyond the PLCC relm.

Any ideas or suggestions????

molding info

got a question

does any one know what is involved in reverse engineering a computer case or other case parts to make new
molds of the original item  just wondering what it would take and if it could be done  

thanks guys

The country can go to shite but they're gonna have to pry my CoCo from

Request for Discussion new level 2 Nitros9 booting.

Ladies and Gentlemen,

I need help from the more experienced contributers and "old timers" of
the Nitros9 community.  I'm trying to iron out some proposed changes
to my new way of booting Nitros9 Level 2.   I believe I have
modernized the CoCo's Boot process to make it more dynamic and save a
smidgen of system memory.  My way of booting is one step of separating
the booting of Nitros9 from the main Nitros9 runtime.  To the
uninitiated here is a simplified synopsis of current Nitros disk
booting:

- DECB's DOS command loads the boot track from disk
- the boot track contains:  REL BOOT and KRN modules.
- REL setup up some system state and moves BOOT and KRN up to high memory
- REL calls KRN.
- KRN sets up some more system state and call BOOT
- BOOT loads the OS9Boot file from the actual RBF filesystem into high memory
- BOOT returns control back to KRN
- and KRN finishes up system initialization and continues to call INIT.

There is some drawbacks to this bootstrap sequence:
1. BOOT is left in memory and it's space is never reclaimed.
2. ALL three modules (BOOT,KRN,and REL) do some setup. They are
tightly coupled, and near inseparable as implemented.
3. Because of the limited space of the boot-track (4608 bytes) BOOT is
limited to 768 bytes of static code, which limits dynamics (AKA
loading from anything but drive 0 is possible but difficult)
4. Separate BOOT source files have to be maintained for each hardware
device (IDE,SCSI,DW, etc...), and likewise, only one OS9Boot file can
exists on any particular RBF partition (..err... drive).  Ideally the

[Color Computer] Multivue under latest NitrOS9

Can someone tell me if there is a trick to getting Multivue to run under the latest versions of NitrOS9?  I just
received my MicroSD pack, with a Nitros 3.2.9 (I believe) and booted it up.  Downloaded the latest distro I
could find of Multivue on NitrOS9 Source Forge.  I have startup loading fonts, stdptrs, all the pats etc.  I
run "control -e" and then "gshell" (autoex) and Multivue comes up, but the top menu line is missing.  If I
move the mouse pointer to the top of the screen and click I get nothing.  Top left corner and click crash. Open
a shell by hitting S, crash.  The slide bars on the bottom and side are incomplete (just the arrows--no bar). 
If I try to run Planet Engine, crash.  Has the latest versions of NitrOS9 broken compatibility with
Multivue?  Is there some trick I'm missi
 ng (for instance do I need to create a 80X25 window to run Multvue now)?

Re: NitrOS-9 L3 Code and Disk Images

Hi Gene!
Gene, Thanks for the reminder.  I had not finished reading all the emails
when I sent the message.  
Thanks for the update on your progress on L3.  It sounds like you and Tormod
really have a handle on NitrOS-9.  I'll be interested in see the results.
Take care my friend.
