CO File Format

2009-09-23T04:59:50Z

Roger:

The structure of a Model T CO file is very simple:

{| border=1
| START || LENGTH || ENTRY || EXECUTABLE DATA...
|}

Where START, LENGTH and ENTRY are 16-bit words in little-endian (Intel) byte order.

START - Where the program is ORG'd to run from.<br>
LENGTH - Size of executable data, this does not include the header(6 bytes), just the length of EXECUTABLE DATA.<br>
ENTRY - Where the program will be entered (entry point).<br>
EXECUTABLE DATA - 8085 machine code ORG'ed at START.<br>

Model 100 ROM

2009-09-22T16:27:10Z

Roger:

The model 100 has different hardware versions, one of the main differances is the ROM chips. Older unit gerneraly have the LH35618 chip and new the 3256C01, which is a 27256 compatible chip.

Steven Adolf has a [http://www.club100.org/memfiles/index.php?&direction=0&order=&directory=Steve%20Adolph document] on this in his personal files at [[Club100]]

The chip pinout are:

MTHD

Roger:

This project it still under development.

The basic idea for this project is to add a harddrive via the [[System bus]] on the 100/102/200

The circut is based on a 8255 which controls the harddrive data and control signals.

A 74573 is used to split the ADDRESS and DATA singnals and a 138 is used for IO mapping

The 8255 is split into 3 x 8bit ports, one is used for address, CS, RD, WR and RST. The other two port are used for the 16 data bus.
