Hello. I found an old Atari 2600 console clone in my basement. Seems to be broken, some parts are missing, but the chips are all OK (CPU and ROM, I guess). Therefore I'm wondering about reusing these parts somehow on a breadboard or something. But in order to do this, I need some information on these chips and their pinouts, maybe some datasheets or schematics. The chips are labeled as follows: 6591 9208A 922511 DIP-48 (two rows of 24 pins each, 48 in total) Seems to be the CPU. WB2600-4MP DIP-32 (two rows of 16 pins each, 32 in total) Seems to be the ROM. As far as I know, there was no cartridge slot, so the games must be stored on that ROM. There's an empty place on the PCB for another DIP-28 chip, the silkscreen label says "IC3 512K MASK ROM", but there is no chip there and it seems that it has never been. HD14011BP 2C26 Just four 2-input NAND gates. MC14024BCP FFES9206 Motorola chip, 7-stage ripple counter, I guess for clock division or something, since it is near the quartz resonator. The resonator is: STANDARD 17.734475 (which I guess is its frequency in MHz) I see no separate TV circuit/chip, so I guess the TV signal is generated on the main CPU somehow. Could it be that the CPU has a TV signal generator integrated in it? I can post some photos of the PCB if needed. But I hope the labels on the chips will be enough for the experts to identify them. Can anyone help me with identifying the chips and supply some descriptions of their pinouts? Perhaps some more detailed datasheets? --- I also found an old Atari 65 XE motherboard. Unfortunately it's broken in half so the chips in the middle of the board are broken as well ;/ But other chips on the edges of the board are OK, so I'll try to reuse them as well. But I'll describe that in a separate thread later.
INTRODUCTION: Not everyone knows that ALL of the Power Supplies built back in the day - including original ones - were unregulated AC/DC Adapters. Which means that the outputted voltage was not stabilized. As a result the poor Atari 2600 was continuously feeded with a voltage fluctuating between 9.8 and 10.40V. Not only - The provided current was spikey and badly filtered, which stressed the console causing heat issues thus premature failures. No wonder that, back in the day, most of the issues on both Consoles and Home Computers were caused by ICs dying after power pack failure. DESCRIPTION: The Deluxe Atari 2600 Power Supply is an efficient item which delivers a current which is not only stable but also clean and properly filtered. Furthermore, being it tiny and lightweight, shipping is obviously much cheaper than a heavy, 30 years old, obsolete Atari 2600 AC/DC Adapter. The Atari 2600 Deluxe Power Supply adds longevity and relief to your console. SPECIFICATIONS: • [email protected] • OVP (OverVoltage Protection) • Highly Filtered S.M.P.S. (Switching Module Power Supply) • 100~240V (Worldwide Usage) PICTURE: PRICE: €18,80 SHIPPING: €6,80 (EU); €8,80 (United States, Canada & Australia)
