Hello, world! Here's what I'm working on right now.
|Project||Current Status as of 12/17/2015||Comments|
|ECB SBC V2||Running||Still sorting out battery backup. Need to sort out hardware flow control on serial port.|
|ECB Backplane-8||Partially Assembled||Five connectors installed. Five caps installed. Still sorting out the screws. Have bigger power supply; will probably need a wiring harness.|
|ECB Disk I/O V3||Assembled||Everything put together, all chips installed, jumpered to defaults per wiki docs. Ready to connect to a disk and test. Will need to burn a new ROM if I'm not mistaken. Have floppy drive, data cable, power cable, 40-pin ide cable, compact flash adapter, compact flash card, and spare eproms for the SBC V2, so I think I'm ready to test when I can find the time.|
|ECB Bus Monitor||Assembled||Finished except for switch T1, which I had some trouble finding. I have what I think is a viable option, now, I just need to make sure the momentary side is on the correct side. I'm not completely sure what the switch is supposed to do, but I don't want to solder it in only to find out that, for instance, I've accidentally set things up where I have to hold the switch to run, and let go to pause… because that sort of thing would be somewhat inconvenient… I can see that it has something to do with wait logic but I need to do more research before I solder that last switch in place!|
|ECB Prop I/O V2||Assembled||Fully assembled and ready for testing as of 12/17/2015.|
|ECB Color VDU||Partially Assembled||Most sockets/components/connectors tacked in place. Waiting on small number of replacements for parts that had minor issues|
|ECB Prototyping Board with I/O decode||Hoping!||New run of boards anticipated! Seehttp://www.retrobrewcomputers.org/forum/index.php?t=msg&th=17&start=0&|
|Sarah's Ad-Hoc ECB Breadboard||Collecting Parts||Collecting several different bare ECB proto boards to compare and contrast. One will probably get some solderless breadboard modules stuck onto it, and a bit of glue logic. Update 12/16/2015: now have five different 160×100 prototype boards to compare and contrast. Will try to post a review at some point.|
|Enclosure for my ECB Machine||Planned|
|Sarah's Signetics 2650 / Pipbug-2K Project||Designnig Prototype V2||
Not currently an official retrobrewcomputers.org project. First prototype working, finally. Working on a rom so I can breadboard and try out some ideas for version 2.
Update 12/16/2015: have decided to do a breadboard version of V2 before designing a new board; I can't decide how I want the decode logic to work so I want to try several different things. My PIPBUG replacement rom now has commands for reading and writing to I/O ports, but at some point, I should probably add code to modify memory, too. Hex or srec format uploads would make writing new code for the thing a lot easier, too. Only need a few hours more work, and a design with more than 2K of ram would be helpful too.
