As long promised I recently updated my article on the Borland commemorative chips and included production numbers where known from the manufacturers records.
I also re-scanned all the chips to show 'consistent' colors. I added the $5 re-order variations but did not alter the numbering system

I have added my stock of these chips to my website. Shortly I will add other Borland chips.
I also added manufacturers sample chips to the site. A few GPI still to come.
Index page for both the above is here:
