steve-chamberlin d1f80fe9c5 Added AVR Studio project file for SIMM Programmer firmware 2016-04-25 13:48:59 -07:00
.settings Fixed bug that screwed up reading after doing an electrical test. 2012-03-04 12:03:02 -08:00
LUFA Updated to LUFA 120219 (with later CDC deadlock patch too) 2012-05-25 19:20:38 -07:00
tests Added GPL header to all of my source files. 2012-05-25 20:21:04 -07:00
usb_serial Added ability to tell programmer firmware to selectively unlock chips. 2013-07-04 12:10:18 -07:00
.cproject Added .bin file generation for firmware upload 2012-03-04 17:28:15 -08:00
.gitignore Initial import of my test code for the SIMM programmer board. Right now 2011-11-25 23:10:30 -08:00
.project OK -- so I separated the actual port code from the external memory controller code. I think this makes more sense. 2011-11-27 00:01:29 -08:00
Descriptors.c Updated to LUFA 120219 (with later CDC deadlock patch too) 2012-05-25 19:20:38 -07:00
Descriptors.h Continued playing with USB serial stuff. I think it's working well now, but I'm running into problems reading from the SIMM, so I need to figure out why I'm not getting the data I expect. 2011-12-10 10:35:41 -08:00

README.md

Description

This project is a bootloader and firmware for a Macintosh ROM SIMM programmer, along with control software for Mac OS X, Windows, and Linux. The ROM SIMM is compatible with the SE/30, all II-series Macs with a 64-pin SIMM socket (should include the IIx, IIcx, IIci, IIfx, and IIsi), and the Quadra 700.
