[Techtoolslist] Adapter for TMS9900 pod to TMS9981 CPU?

[John Robertson]

TI's TMS9900 series CPUs - I have a game (Universal's COSMIC GUERILLA) 
in the shop now that uses the TMS9981 CPU and while I have the TMS9900 
pod I do not have an adapter for the TMS9981. Pretty sure I have a RAM 
(4116) issue, but before I go down the rabbit hole (convert to 4164s) 
I'd rather run a RAM Test...

Anyone have that interface sketched up?

Or am I going to have to make it from scratch...(lazy & it costs the 
customer more of my time)

Anyone have any TMS9981s lying around? It is possible mine are defective 
too.

Thanks!
