matsoprocessor

Hello, Aleksey Bezlutsky! I remember that on May 12, 97 you took it and launched
in All with this:

AB> Hello everyone!
AB> recently got into IBM's assembler and found out some interesting commands there. These are commands for accessing the mathematical coprocessor. So this is what I
AB> am leading to. There is an idea to make a similar mathematical coprocessor on
AB> SPECCY.
AB> How do you like the idea?
AB> I do not mean that you need to use
AB> a processor from IBM. I think that a processor from
AB> of some calculator would be suitable for this role, if possible. The main thing is that he can
AB> execute at least the following commands: + , - , * , / , cos, sin, tan,
AB> arccos, arcsin, arctan. since these commands, especially cos and sin, take up a lot of computer time.
AB> Data for the processor can be transferred, I think, through the same stack
AB> of the calculator,
AB> and return the solution there.
AB> but there is one small problem here.
AB> All mathematical processors, mostly
AB> 12 or 16-bit. And when
AB> connecting it to an 8-bit SPECCY, as you understand,
AB> problems will arise.
AB> So if there are craftsmen who can still connect
AB> some
AB> processor toSPECCY, I think everyone will be very grateful to them. After all
AB> imagine what speed can be achieved when constructing
AB> three-dimensional graphics and in general
AB> calculations.
AB> Do you think this is a worthwhile idea?

Worthwhile, but why a calculator? They say there is a support from the Z80 kit.

bye, with all sorts of Wishes, Fedin Pavel!
