SINGLE BOARD COMPUTER USING PROPELLER ICs AND TRIBLADEPROP PCB
           IT'S RUNNING jumpin
 
8th April 2009:   for details and photos see the thread...
Also see links to other threads in my signature for more details 
 
--------------------------------------------------------------------------------------------------------------------------------------------------------------
Thread renamed from "Propeller Based Single Board Computer on TriBladeProp" 22Mar2009
 
Well, we are nearly there...
 
The TriBladeProp has all the required hardware for a single board computer. It has 3 propellers on board (called Blades), plus connectors for VGA, TV, PS2 Keyboard, PS2 Mouse, microSD, and 2 Spin-Studio. Also on-board are Static RAMs, Flash and EEPROMs plus a built-in PropPlug and Power Supply (5V and 3V3) for an external plugpack (walwart?) 7-9V DC (center positive). The TriBladeProp has been designed for the hobbyist to assemble.
 
So, my concept here is to separate the "Processor", the "Terminal", and the other "I/O" into self-contained propellers. This is a relatively cheap and simple solution and the whole project is of course propeller based.
 
The TriBladeProp concept is...
* One prop/blade handles the "computing functions" with on-board external Static RAM and microSD card (PropDOS or emulation software such as the Z80 ZiCog)
* One prop/blade handles the "Terminal functions" VGA/TV/Keyboard/Mouse for a self-contained color (or graphics) terminal
* One prop/blade handles any extra "I/O functions" including 2 Spin-Studio connectors
* plus a serial interface to the PC (via the inbuilt or an external PropPlug or equivalent)
 
Software for the SBC (native Prop code)...
* PropDOS has been done by OBC so just needs to be tailored for the board
* A Prop Editor has been done by mpark and OBC
* Just need a native spin/pasm compiler and we are ready to put it all together
* Terminal software has been done thanks to OBC and others
 
Software for the SBC (various microcomputer emulations)...
* ZiCog (Z80 & CP/M) emulation by heater is almost ready to run
* PropAltair emulation by heater is almost or done
* Other emulations are work-in-progress
 
The TriBladeProp is not the only solution here. It is just one solution.

Hi! I'm Carlo from Como, Italy

I am really fascinated by your project; unfortunately I do not have the ability (I've never do that, I'm a chemist dating back from '80 electronics)to solder SMD's.

Will it be possible to have the circuit board with all SMD's pre-soldered?

Thanks so much

Carlo

Looking at the board, seems like you have the same problem I do - the FTDI chip and SD card are both SMD only. Also looks like you're also using the only Through-hole USB (type B).

I know that most hobbyists won't do SMD soldering. It's a deal breaker. Not sure what the solution is (other than pre-assembled breakout boards), but if you figure it out, let me know!

Most "end mounted" SD adapters aren't show stoppers, but the FTDI chip would be.
Shame they don't make a DIP for this.

*edit* Looks like there are standard prop plug interfaces everywhere anyway, so the FTDI on board may not be required

There is a FTDI breakout (to DIP) on Sparkfun.
There's also other 0.1" friendly modules like the MB5 from 4D

Normally you only need a handful of connections to the FT232. Why couldn't they do it in a 8 pin DIP/ TSSOP (without leds) ?

Dossic, I'm getting 4 of those boards, they have few SMT parts, I can solder them for you and mail it to you. I'm in Freiburg, Germany. I'm also a chemist :-).
I think Cluso can also do that for you, just ask him. Most parts are DIP, though.

mctrivia,

I have had three "brain heart attacks" (strokes) in the last three years. My mental and physical abilities have come back, due to brain plasticity.
However, my fine motor skills in my right hand still sucks beets,

If I supply all parts, would you be willing to take me on to your generous offer?
I am in Austin, USA. Take the time to think it through - your time is precious, too.

ya no problem. can either order myself(i do regular orders from digikey) or you can send me the parts and I can assemble for you. I should have mentioned also that is $10CAN plus shipping.

For any parts you want put on just give me a list of digikey part number and quantity. Digikey ships to me for free so for parts orders you only need to pay list price plus 5% GST(I do not have GST account yet so I have to pay it) If you already have parts and wish to ship them to me I can give you my address if you pm me(just a note when you ship to me the government tacks on the 5% also evil tax)

If multiple people are interested in me assembling Cluso99 could send me the prop blades direct.

The two mandatory smt parts are the FT232RL (no choice but it is the easier smt package used). However, you can use a real PropPlug in it's place.
The other is the microSD. I changed the part to one which can be touched up (read hand soldered) with exposed legs on the outer edge of the pcb. Likewise the alternative is to use an SD card and run the wires to the microSD vias which i have provided.

I have bought both TO220 (T/hole) and TO252 (SMT) Regulators. The SMT are easily soldered and provide a neater solution, but both options are on the pcb.

I can solder these parts on for a small cost. (Thanks to mctrivia for the offer and you are welcome to use his service). I will have to order extra parts from digikey for this as no-one had wanted parts. The real cost in this is the shipping from Digikey which doubles the parts cost to me. The ones I have already brought in (low volume) have this shipping cost penalty. If you require these smt parts let me know and if you require any of the other parts as well. As you will see, most parts come from Digikey although a few are from Future Electronics. Only takes a week to get here (Australia).

I will post more info once I have soldered my first pcb. They are due to be shipped to me today (hopefully).  tomorrow cry  As soon as I have them I will post a photo of the pcb. :-)

Software: I have discussed with OBC about PropDOS and the Terminal program, etc and I will do any mods required and post the code here for download. Likewise, the same applies to heaters ZiCog code.

Exciting stuff Cluso99,

Dontronics have FT232RL's in stock. He'll happily sell you 1 or 100 and it should be quick and cheap enough just by aussie post.
Glyn are another "local" option

Thanks tubular - Dontronics hey - they have been around for almost as long as I can remember :-) But the microSD still have to come from Digikey - I don't expect to find them in Australia.

PCBs not being shipped until tomorrow :-(

Thanks Ale, I'll keep you informed.
I was just so excited with Propeller that I was thinking, when I saw the presence of large SRAM, to use it to design an intelligent potentiostat. But time is the limiting factor, I have to face with all my burocratic and Academic duties.

Anyway, I am writing a simple software for controlling stepper, relays and so on aimed to chemist's needs. It's great to forget interrupts and using the power of the 8 processors. And, finally, I started enjoying OOP....

Thank to you all

Carlo

Posteditted:

Do you like the black resist?  
 
I will email to those who have requested pcbs over the w/e - done.

The SMT microSD socket and TO252 Regulators were easy to mount. :-) 

The FT232RL is another matter - Rework done (used solder wick to remove excess solder where some pins were joined)  cool

Board working with 3 x 512KByte SRAMs, VGA, TV, on-board PropPlug, etc (EEPROM & FLASH not fitted yet)

See the TriBladeProp thread for latest photos and Errata.   http://forums.parallax.com/forums/default.aspx?f=25&m=329999&p=3

Just thought I would update progress...

SUCCESS...jumpin

All propellers are running, with SRAM, VGA, TV, on-board PropPlug equivalent, etc.

ZiCog v0.5 is now running using the SRAM so see the ZiCog thread http://forums.parallax.com/forums/default.aspx?f=25&p=1&m=332138 for more information (Z80 emulator with CPM). Now to get the disk working using SRAM and microSD.

PCBs have been sent out around the world. cool

TRI-blade - is there any cross-pollination with www.machineinteltech.com/?
I really don't think so, but I need to ask to be thorough.

Do you anticipate a revision in the layout to accomodate the changes sice you created the prototype layout?
My answer would be yes, but you may have other considerations beyond the purely technical.

JMH: No, no connection - interesting site tho'

No, I am not planning to update the pcb. It is doing what I expect. The only real modification is an either/or for the SRAMs, so it would still require a link on the pcb to select which method to drive. The modification for 2 SRAMs is actually very easy once I post the photos of how to do it (TBD).

As an update, heaters ZiCog is running and I now have the SRAM 960KB Disk emulation working (all on Blade #2). I just need to get the correct code into the SRAM or modify for 137 byte sectors (WIP). See the ZiCog thread for all the work underway

SINGLE BOARD COMPUTER USING PROPELLER ICs AND TRIBLADEPROP PCB
                                   IT's RUNNING jumpin
 
for details and photos see the thread...
Also see related threads in my signature below.
 
Uses PropDOS/PropCMD, PropCOMM2 (VT100), ZiCog and a TriBladeProp PCB. Currently only 2 Propellers are being used and no interaction is required with the PC. 
 
Thanks to Michael Rychlik (heater) for ZiCog; Roger Williams(localroger)/Michelli Scales for PropCMD & Jeff Ledger (OBC) for PropDOS; Radical Eye Software (Tomas Rokicki) and Mike Green for fswrFemto; Mike Green for sdspiFemto (which is the ultimate PASM driver for the SD and EEPROM); Andy Schenk for PC_Text & PC_Keyboard; Parallax, Inc.(Chip) and ?? for doing the Plus extensions for FullDuplexSerialPlus; OBC for PropCOMM2-VT100 [a self contained Terminal program]. My apologies to anyone I have wrong or missed - please PM me so I can include you. There have been so many others who have helped me along the way to learn the prop, including especially Hippy.

This is way cool. I am inspired by this project. CP/M-80 was a major milestone on our way to microprocessors in personal computers. I know prop chips are used for all kinds of things, but I am a systems guy, and using the hardware and software to provide the system infrastucture for an SBC seems VERY elegant to me. I will be fascinated to watch and participate in this project, as it has so much potential. The disk drive compatibility aspect is a fantastic way to leverage off the existing inventory of software assets for the CP/M-80 environment.

Keep up this amazing work that has so much potential for fun and education about vintage computers.

Welcome Douglas. Hope you can get yourself set up with ZiCog and CP/M on one of the many Prop boards that can run it now: TriBlade, RamBlade, DracBlade, Morpheous or even the Hydra with RAM expansion. Most of these have their own threads which been quite active recently.

For me, the past is not over yet.
