At the moment there are no interfaces available due to shortages of the chips used in them. I'm working away from home until at least the end of this week but I may have some interfaces in a couple of weeks - I have parts due to be despatched on 11th of this month, I'm just waiting to see if I get them or if the date just gets moved back.

Ok so what I’ll need is a Suzuki ecu with the 84 pin chip to be able to identity the circuity that leads to the mode pins as there is no pinouts for the 100 pin chip.
Which ecu you have worked on does that 84 pin chip come in?
What rom size do you allow for and how do you determine the rom size or is it a case that the ecu will only dump a certain size ?
For example my H8 ecus dump a rom size of 128kb and the sh ecus dump a file of 256kb
The MH63 should be a 76C55, I have an adapter to read the 84-pin devices but I have not got one for the 100-pin packages. Pinouts for the 84-pin series are here: http://rhinopower.org/76xxx/76xxx.html the 6301 datasheet and handbook describe special test mode, essentially you need to boot with both the mode pins connected to 0V. In that circuit I use a counter to disable external reads to the top of memory after a small number of clock cycles to allow the interrupt vectors to be read.

from browsing the site I have come across the attached pictures but the actual process of connecting to the board and entering special test mode I have not found.
i have traced some of the pins on the chip and documented what I believe them to be .
I've been able to get TASM working with MINIDE so I've written a document that explains how to set this up. This makes modifying the code a little easier with no need to use a command window.
I have been using MiniIDE a lot lately to write test software for the 8V MH6211 and MH6111 processors used on the 8V Track/Kick/Vits. Its a 68HC11 environment but it can be used 'out of the box' as you only use the 6801 supported instructions. The coloured syntax is much nicer to work with than the plain text in Notepad.
For writing programmes that use the more advanced features of these processors then MiniIDE can be used to write the code and the Telemark TASM assembler can be used in a command window (not suitable for 64-bit OS!) works but the syntax is not compatible with regular 6801/HC11 assemblers.
Utility to convert from Motorola format programming files to binary files for use in an EPROM programmer, may not be required if your programmer supports S records:
