Oric ATMOS 48K
« on: February 20, 2021, 07:09:24 PM »
Hi,

Does anyone have a similair interest or fond Memories of the Oric Atmos 48k?

When ive finished my Zx Emulator "BlitzMax". Im thinking of starting to write an Emulator for the Oric Atmos moving onto the C64.
The main reason is to venture into the 6502 world. Im intersted into wether other people would be interested in doing this also?

Im thinking of trying the Oric first as it seems closest to the ZX Spectrum which im familiar with. But the C64 has one of my favourite retro chip's the SID. So once ive done the Oric. I'll Move onto the C64 which will then be eaisier i think  :-X

Emulator's take a long time to write from scratch! So id be interested in hooking up with people with a similair interest. If there are any  :o  interested in writing an Emulator for one of the following preferably the ATMOS first.

This project could be upto 6 month's off from start of post. But the main things that need to be re-searched are :-

1 : Memory map
2 : 6502 Instruction's. UN-DOCUMENTED are a must!
3 : Video resoloution and it's modes
4 : Ay sound chip

Main critia is any code must be written in BlitzMax 1.5 ONLY! NO ADDITION'S OR FRILL's
Preferably written in Functions

So im, interested in thought's Idea's and usefull Link's I think no more than 5 people as it get's complicated to co-ordinate! It's a great way of learning to code and at a basic level to learn how to code in 6502.

It might only be me LOL's  :))

Kind Regards Baggey

Seen them, but never used one... Having a scan though the manual, I spied a BASIC command called SCRN(X,Y), suffice to say, I think that would of been one heavily used command for BASIC games! :)

Makes me want to buy one to try it! lol

Im Looking at Z80 Code and then Looking at 6502 Code and i cant't begin to fathum what the F**K 6502 engineerer's were thinking! And why it was introduced and written in the way it is!

In the 60's and 70's there were a lot of "psychedelic drugs"  ??? I think the people who wrote the manual for the 6502 were on them! BIG TIME :))

The first quest to write a 6502 emulator is to Keep It Stupid Simple! And rewrite the 6502 index so it's understandable WTF!  :o No wonder the 6502 lost out to the Z80.

An Americain phrase i like is the KISS rule!
