Dear Fred,

Your latest issue just arrived, and I thought I'd better get the subscription 
off before I forget - like last year.

I notice that you have gone to the yellow paper, I guess as a deterrent to the 
repro route. How much of a problem is that???

I would like to open a line of communication with you regarding various 
peripherals now (and future) in the works. It seems to me that our prime 
responsibility is to the poor Arcade owner, most of whom bought their machine 
in anticipation of some sort of Bally add-on. We, together, should ensure that 
the "things" we are working on are compatible with each other and probably 
should not be exact duplicates. Let me expand a bit.

I note that you are working on a keyboard, as I am also. Near as I can tell, 
they are certainly not identical pieces of end-item, may even "attach" to the 
Bally by different methods, and as such, will provide the owner with a choice, 
and therefore be beneficial to him.

In the area of memory, language, etc., I think it would be detrimental to the 
owner if what we provide separately is not compatible. For example, if memory 
access space is at a totally incompatible address location. We are using 6000H 
as a starting address in our Blue Ram scheme, and the new language cartridges 
we are working on will be compatible with that. I would strongly urge that 
anything you have planned - that needs a specific address - be at a minimum 
value of 6000H, so that the owner will find as much flexibility as possible for 
his buck. If you have any similar requirements, we'd like to hear about it.

By the way, I'd appreciate the following ad in your paper:

"The ARCADIAN has been published for BALLY owners since Nov.1978. Tutorials, 
programs, and hardware data are included. Free sample issue. Subscription is 
$10/yr. 3626 Morrie Dr. San Jose CA 95127"


Looking forward to your comments,

Yours truly,
Bob Fabris
