- Feb 15, 2014All —As an update, I received the second turn of the prototype and it works fine. As of now I have two spare boards for sale @ $30 including shipping in the US. If there is enough of a demand, I can do a larger run (like 20 units) and get some better pricing. Drop me a PM if interested.On the Serial IEC interface part of it, the DOS command code is kind of rough at this point — some commands work, other’s don’t, but from machine language it works fine. I’m trying to get a “LLIST” command to work in BASIC because I think that would be useful. If the IEC interface isn’t needed, the parts don’t have to be installed.I’ll put together a full net list shortly.Thanks!From: Richard Cini <rich.cini@...>

Subject: New 6502 SBC pre-announcementAll —Just a quick FYI, I did a major redesign of Daryl Rictor’s 6502 SBC v.2.5 to make some needed improvements and add some neat features. I’ve done one prototype run (which works, but needs two cuts and four jumpers) and a second run, which is due next week.The improvements are as follows:
I’m made changes to the included EhBasic to support the Commodore Serial IEC protocol. It works and supports all Commodore API commands using assembly language and some BASIC 4.0 commands from EhBasic.Pricing on the bare board would depend on quantities and if there’s sufficient interest I’ll make a bulk order. Attached is a PDF of the board plot for those interested in looking at it.Enjoy!
- Resized board to 6.375” x 4"
- Bypass caps on all chips
- On-board DE9F for the console
- Pushbutton reset switch
- USB Mini-B jack for power
- Power LED
- The big one — Commodore Serial IEC interface with SD2IEC header.
