Go to file

Doug Brown 2c3202af3b Update README.md Updating in preparation for latest release. Changed a few descriptions and removed some unrelated things.		2020-11-26 23:41:14 -08:00
.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
cdc_device_definition.c	Added GPL header to all of my source files.	2012-05-25 20:21:04 -07:00
cdc_device_definition.h	Added GPL header to all of my source files.	2012-05-25 20:21:04 -07:00
chip_id.h	Added GPL header to all of my source files.	2012-05-25 20:21:04 -07:00

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
external_mem.c	Added ability to tell programmer firmware to selectively unlock chips.	2013-07-04 12:10:18 -07:00

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.

This particular repository contains the main firmware that runs on the programmer board. The current compiler version used with this project is avr-gcc 4.8.2. Using a different version of gcc may result in worse performance due to some very tight optimization performed on this project to decrease programming time.
