It's one of those field programmable PROMs, where you burn out internal tungsten fuses and change bits from 0 to 1. 24S10 and 14S10 are cousins, 3-state and open collector outputs. (eyes) 82S129 74S287 24S10 14S10 82S126 74S387 24SA10 (not 187) I've also checked those sources few times, but my French is lacking. Some text manipulation things I found, but cursor positioning is not straight forward, at least in names and numbers. E, property mixup. E2, more files. And it's possibly that 24S10 that is more relevant. E3, less files. PDF is from Datasheet Archive, but can't figure out the search phrase. E4, dang, 187 is a mask ROM. |

Yes, still want it, 24S10 that is. And it's even better now since the earlier OC output knowledge was inaccurate. Upper line of the earlier post is 3-state and lower OC outputs. We can figure out the rest when you get them. Generally old PROM types are good to have, PALs are much less needed around old TE, I guess. For 87C51, I think I've seen one in HP 3478A. The mentioned mask ROM is my pokings around the net and nothing to do with other things. But are you sure you don't need that 24S10 your self? I have a recollection that you may need one, but the sign is not bright. It's sometimes used as a substitute to discrete logic chips, design time is probably somewhere before PAL chips, early '80s I guess. Usual place is an address bus where output side is logically complex, those are faster than regular ROMs. E is edit. Keep'em or not is always a thing. |

You are instilling doubt in me now, MK... I am starting to find thse 24S10 sexy as hell... maybe I will keep some of them... depends how much there are in all ! We shall see ! ;D The 80C51 I am impatient to get my hands on... as it will bring back some memories. In 1996 at school they started teaching us micros and assembly language on a (actual/vanilla) 80C51 development board, with 64K of external memory. Half of the was an EPROM containing a monitor, the other half was a 32K RAM chip into which the monitor would download the user program. Then the next year in 1997 we were blessed : we had a different dev board... still 8051 based but this time a super duper variant of it : the 80C552 ! Was the state of the art 8051 back then... fancy PLCC package, PWM, lots of I/O, ADC, I2C, even a H/W multiplier IIRC but don't quote me on that...it was a monster back then ! :-DD |
