I'm restarting a couple builds that have been collecting dust on the shelf for the last 2 years. I should have most of the parts but a BOM would be a handy reference to go with the board layout. Does anyone have a BOM for the 6x0x-ATX-6U revision 2-013 board? I see that Alex posted an excel file with part numbers but the links on the introduction page are not working. Thanks. Nik

Page 1 of 9 ---- Generated from RetroBrew Computers Forum I will try to spend some time in the next week updating the page for this board on the new wiki.
The software was kind of spread across the old wiki too, some of it was dual use with the old three-board stack 6x0x and the new version.

The 68B09 (B is speed variation) is the preferred (faster) chip. The board cannot use the -E variant.

I plan on installing the 6809 and running flex, seems to be alot of software support for the flexos. A pity the board cannot use the 6809E cpu, love to be able to play the Cuthbert games from the old Coco Computers.

I am not aware of an instruction set difference between the 6809 & 6809E. I suggest giving the game a try. If the OS runs, then the game likely runs.

The 32K SRAM "skinny DIP" is proving to be a little difficult to find in the usual places. Jameco part 75037 is no longer available. I have searched by description at Digikey but they dont seem to have the corrrect package type. Any suggestions as to an alternative part? The description i am using from the Jameco catalog is "AS7C256". Thanks. Nik

Since i'm building an order with Digikey i'll go with the IDT71256 25ns, couldnt find anything faster that was in stock. hopefully it will work ok. The board is looking good now with most of the solder work done. Just waiting on parts now. Final question about the CPU, i am seeing 68B09EP, EF68B09P, MC68B09P, on Ebay and then there is a HD6809P which i have in my draw at home. Will any of these do? Nik

Make sure the CPU# does not have any -E suffix. The -E version is electrically incompatible with the board.
Specifically, one of the CPU's you mentioned had the suffix "-EP". Don't get this one. -P suffix, on this and other parts, just means "plastic" package, rather than ceramic.

Subject: Re: 6x0x-ATX-6U BOM Posted by brizza on Sat, 01 Apr 2017 14:12:15 GMT View Forum Message <> Reply to Message Hi, Getting closer to completing the board now after a long wait for parts. I plan to run flex but i'm having problems with the PropIO. After reading some of the archived posts i think i may need to recompile the existing spin code for the eeprom. Just wondering which compiler was used for the original code provided in the ZIP file on the wiki? The Parallax Compiler Software does not recognize #define and the BST Compiler is also throwing out errors in reference to the definitions. The board has video but output did not go further than;
Starting PropIO before mount after mount
After commenting out the #define statements and removing references to CP/M and DOS65 i get a little further;
Starting PropIO before mount after mount in FindSDblock FLEX_0.DSK=01A0,R T:00 S:02,Disk geometry: T:79 S:72 FLEX_1.DSK=0CE0,R T:00 S:02,Disk geometry: T:79 S:40 FLEX_2.DSK=1320,R T:00 S:02,Disk geometry: T:254 S:255 FLEX_3.DSK=9224,R T:00 S:02,Disk geometry: T:79 S:36 FLEX.SYS=0190,R T:00 S:02, Disk geometrty: T:0 S:0 after findSD Disk buffer start=393C
I'm using 64MB SD cards, Kodak and Sandisk. Serial output not tested yet but should receive the headers this week sometime. Any suggestions would be welcomed. Thanks, Nik

Subject: Re: 6x0x-ATX-6U BOM Posted by Andrew B on Mon, 03 Apr 2017 15:53:33 GMT View Forum Message <> Reply to Message Parallax has changed what tool they want you to use to compile stuff for the Propeller several times in the last few years.
I would recommend trying the 'PropellerIDE' tool linked here - https://www.parallax.com/downloads/propeller-p8x32a-software - which is the newest Spin langauge tools. ('SimpleIDE' is a different tool for C code)

Subject: Re: 6x0x-ATX-6U BOM Posted by borutk on Mon, 03 Apr 2017 16:45:21 GMT View Forum Message <> Reply to Message Hi Nik,
Default image to burn in prop eeprom is in zip file: /6x0x_flex9_27072014/prop_io_flex/propIO.eeprom.
As described in /read-me.txt: There are two configurable options for running FLEX, serial port and vga/ps2. Production boards incorporate a jumper J3 for this purpose.
If the jumper is missing it works in serial mode so it might just be that your board perfectly works as intended. What can i say, i am lazy and i prefer serial comm for development.
Anyway, i would suggest you to first try attaching serial cable to serial port (9600, 8N1) and start the board. If ASSIST09 monitor starts you at least know that 6809 part is working, otherwise debug this part first. WDCs W65C51 are crap and they do not work, they have a bug on TDRE flag in SR. WDC has known this for years and never fixed it.
Enter
Compiling Prop code should be done with BST, i usually also use the GUI.
As others have said, you can use xx68y09P or HM63y09P, first letters xx are just manufacturer (MC - Motorola, EF - Thomson, HM - Hitachi) y can be nothing - 1MHz part, A - 1.5MHz, B - 2MHz. HM63C09 comes in 3MHz variant, but i don't see much use of it because there are no 3MHz parts for MC6840 (PTC - needed for single step debuggig in ASSIST09). Also, 6821 only come up to 2MHz. You might try using WDC's W65C21 but after a fiasco with W65C51 i never bothered to check them.
Best regards,
