Norm,

I believe Kevin B and I understand the problem with the WB14
and the Trinity configuration with MOS.   We have re-arranged the 
interrupt  structure  for the 68K and it is not  compatible  with 
MOS.

I'll  be in this A.M.  to talk over problems so get them together 
because I have to be at Unisoft in the P.M.

I'll  have to check further on pricing of 5412  and  5619.   This 
seems drastically wrong.   In my office on the wall is a chart of 
parts  and costs--probably a more realistic price is on there but 
we'll talk about it when I come in.

Is  %take fixed so it returns a prompt when finished??   My  copy 
(from the 1.67 patch disk) doesn't.


Also regarding cu... does %! <command> run a shell command and return
to cu correctly?  It doesn't on my machine.

NOTE:   My 1.67 patch disk worked funny.   I loaded it  o.k.  and 
        updated and the sum came out correct.  But when I went to 
        reboot,  it  did  not come out as a file to  boot  option 
        although  it was in my / directory and it had the correct 
        sum.   I  guess  it didn't have the "large"  bit  set  or 
        something cause it was executable.  Anyway I copied it to 
        another file,  erased micronix and moved it back and then 
        it came up as file to boot option.   Note this was one of 
        our standard patch disks too!.




Kevin M.,

Please  find  in my directory (/a/bob/Trinity)  the  trnspecs.doc 
message with my comments inbedded in it.   I have no problem with 
the dealaer memo document just comments on the spec.  The updated 
commented on is also on the floppy in the "b" drive.




Splendor,

Please stuff all components possible in the SP188 slave board  as 
soon as possible so we can start debugging it!



Kevin B.

I  have Ken Tolland working on schematics for the  SP188.  Please 
let him know I'll be in this A/M to answer questions on it!

Did  you  locate the SP188 parts list O.K.?   I beleive it to  be 
accurate but you might have Splendor check it. 

We  are  going to need to burn new PALS (14L4) for  the  68K  CPU 
board and need a tube of them.

We  are  also  going to need some blank 2732A-20  chips  for  the 
CPU68K.

We  will also need some 7649 Bi-polar proms for the HDC/DMA 14D-G 
and 15d-G locations for Trinity.

We need to keep up on more power supply samples.  Please get with 
Kevin M to be sure these get flushed out of Japan.

What about the new Trinity logo plate for the show machines? 

Trinity  is  going to need data cables which have  the  following 
pinout:
		2	-	2
		3	-	3
		7	-	7
	       20	-      20		

Trinity won't run at all without pin 20 support!!
