Matt, I could supply you with a copy of absolutely any diagnostic disk for TestBook that you might require from our library of about 50 or so, and to boot, i could also supply you or MHM with any cabling schematic for any TB lead, in fact as we have all the parts including all connectors and custom made adaptors, i could in fact supply you with not only any lead you wish, but i did also develop a really cool item called a leadmate that has a button pad and LCD and could be used to replicate any of the many TB leads. But that project got canned.
And i will also tell you that for an L322 (pre 05 at least) you need a DTC0065 (Red OBDII) lead
But, regardless of any degree of nobility you may have, let me tell you catagorically and out right that you will be totaly wasting your time if you think either will produce a workable diagnostic system. You must appreciate to some degree that you cannot directly plug ethernet or USB into a vehicles OBDII socket and as such you will be missing a most vital interface part.
I am sorry that it is me being the fly in the ointment of your plan, as we produce LR diagnostic equipment, and as such i might well be expected to say as much, but then that is exactly that reason why i uniquely have such a very detailed knowledge of the both the TestBooks hardware and software, now spanning over 15 years.
In my time i have upgraded and repaired loads of all different versions, modified and updated them and even built one in a standard PC on a couple of occasions. Even now i am freely helping a chap called Matthew In SA rebuild one from scratch, updating it's CD drive and fitting a floppy drive to it, so i really do know what i am talking about.
Re producing TestBook hardware is not actually a new idea and has been the holy grail of so very many since the TB was first introduced. It was in fact where it all started for me, and i had TB software running on a Toshiba Tecra laptop almost 15 years ago for all the good it did.
To all common knowledge and understanding, re producing a working set of TestBook or T4 (its later incarnation) interface hardware has proved simply impossible, and to date, to everyones knowledge (else we all would have heard about it) no one has ever managed it and released it.
I phrase that last paragraph quite carefully, because i myself do actually know of just one guy who has actually managed to do it very sucessfully, to the degree that it actually works much faster and better than the origional equipment ever did.
If you or anyone is interested i will happily spend some time explaining everything you might ever wish to know about Testbook and T4's interface hardware and exactly how I managed to duplicate it.
