An area to collaborate on all the memory addresses found in ROMs

OBD1 Civic Integra ECUs share a lot of features

ASM662 - can be used to assemble and disassemble these ROMs.
OBD1 Conversion Formulae - can be used to convert values found in these ROMs to real-world values.
OBD1 Code Compatibility - describes the various ways you can run code in an ECU other than what was intended.
Some 66k Assembler Routines - have been commented, and you can look at the commented OBD1 Civ Teg Routines.
Auto Or Manual - There is an interaction between hardware and software to determine transmission behavior.

Everything else OBD1 - usually 66207 based MCUs

OBD0 Vtec ECUs ECUs share a lot of features

PW0 - ROMs based on the PW0 JDM (89-91 CRX/Civic EF8/9 B16A) but also included is some of the Euro PW0 locations.
PR3 - ROMs based on the PR3 JDM (89-91 Integra XSi B16A)
ASM662 - can be used to assemble and disassemble these ROMs.
OBD0 Vtec Routines - have yet to be written.

OBD0 MPFI ECUs share a lot of features

91 PM6 - ROMs based on the 91 PM6 (USDM CRX/Civic Si w/ SOHC D16A6)
91 PR4_PA - ROMs based on the USDM 90-91 PR4 with internal PA sensor
90 PR4_no_PA - ROMs based on the USDM 90-91 PR4 w/ external PA sensor
91 PM7 - Although very similar to the 91 PM6, George Ricketts and others have done a lot of development with the PM7

OBD0 PM6 PM7 RAM_Locations - the PM6 and PM7 code seems to store important values in really similar RAM locations.
OBD0 Conversion Formulas - can be used to convert values found in these ROMs to real world values.
OBD0 Code Compatibility - details what code can be swapped into which ECUs.
OBD0 MPFIRoutines - are often shared between ECUs.
Intel8051 - assembler/disassemblers can be used with these ROMs.
