CPU datasheets wanted - 6802, 68A09, 8741, AM2910
I'm making an effort to get together datasheets for all my scavenged ICs, but CPU ones seem particularly hard to come by. Has anyone got any datasheets on the following (old!) chips? 6802, 68A09, 8741, AM2910 I *think* the 8741 is a CPU, just with on-board EPROM. The 8751 is IIRC - an 8051 with on-board ROM. I can't find anything on the 8741 though. The AM2910 I gather is more of a CPU core, around which you roll your own instructions (which could make an interesting project!) cheers Jules |

Has anyone got any datasheets on the following (old!) chips? 6802, 68A09, 8741, AM2910 I have the sheet for a 40-pin Nat Semi IDM2910A Microprogram controller, also called a microsequencer. It was used in conjunction with AM2901/IDM2901 4-bit ALUs to construct discrete bit slice CPUs. - Franc Zabkar -- Please remove one 's' from my address when replying by email. |

news I'm making an effort to get together datasheets for all my scavenged ICs, but CPU ones seem particularly hard to come by. Has anyone got any datasheets on the following (old!) chips? Not sure if any of this is what you are looking for, but... 6802, Fairchild F6802 / 6882 CPU (3 pages) 68A09, Is that the same as the Motorolla MC6809 CPU? (6 pages) 8741, NEC uPD8041/8741AD - Programmable interface. Description and features only, no pin-out. AM2910 Found nothing in my databooks :-( I *think* the 8741 is a CPU, just with on-board EPROM. The one I found claims to be a single component 8 bit microcomputer which interfaces between the processor and many peripheral devices. Is any of that of use to you? |

I have about 20 of them pulled from a phone exchange a few years ago. Have you got the info in pdf format that you'd be able to email to me? Franc kindly sent me info on all the others, so it's just the 68(A)09 that I'm missing. cheers Jules |

Have you got the info in pdf format that you'd be able to email to me? I only have it in printed form and would need to scan it... so we would be talking of .gif images or possibly .rtf document. I see someone has a link to a pdf, check that out and let me know if you are still stuck and could use scanned data. |
