What type of chip would be good for an FDC. We map away wrong codes or sometimes logistic variants. Page 2 of 2. Speaking of vagaries of VIA usage, this computer my KimKlone has opcodes that talk to one of a VIA’s bit counters, rendering it part of the programming model.

The general trademark of a manufacturer by which the consumer knows its products. The brand’s unique identifier for a product. The idea for use like on a parallel printer, where you write to the port for example, one line tells the printer, “I have new data for you,” and the datashert takes it and uses the other line datasehet say, “Thanks.

The have these also, and I have only used them for other things. Datasheeet application needs at least 5 hours for publishing information about new products. That doesn’t mean you have to give it only four addresses. It’s generally two to the power of however many register-select inputs there are. Sat Aug 03, But the data-sheet is not yet standardized by an Icecat editor. Offhand, I’d say you made the right choice!

Bit 0 ie, the bit whose value is 1, the number you put in your first line has to do with enabling interrupts caused by an active edge on CA1; so that’s not what you want right now.

Sorry, this information is not published yet! Tue Jan 15, 5: You can give it a lot more to make your address decoding hardware simpler and just not use more than four.

I found a datasheet at http: So going off this example: Tue Dec 11, 8: So, I used an inverting bus tranceiver 74HCT to connect it to the rest of 74htc640 system. Category Does not fit in any category. A manufacturer can have multiple brand names.

Tue Dec 31, 2: I remember that the little proto-board project that I did with the about 27 years ago! Moreover, I needed the counter to increment, not decrement– again, something you won’t find on the data sheet!

Sacramento, CA, United States. I dug it out and had my co-worker take a picture of its long-dead corpse.

If you do give it more, the four you need will get reflected in other addresses; but if you don’t use them, it does not cause any problems.

Multiple product codes can be mapped to one mother product data-sheet if the specifications are identical. Actually though, unless you know for sure that all the other bits in CRA are 0 and you want to keep them that way, it would be better to use an instruction or sequence of instructions that sets only that bit and leaves the rest unaffected.

Users browsing this forum: An alternative solution — besides a jumble of jumpers on top of jumpers — would be to redefine the pinout by turning the chip upside down, and then bending the pins around or soldering to some sort of adapter. I like how you fixed it in software! Google [Bot] and 0 guests. Previous topic Next topic. Thanks for looking that up for me, Garth.

Product name is a key part of the Icecat product title on a product data-sheet. Download the free Open Icecat data-sheets. I’m ready for another byte. Cool — so you have d0 on one IC connected to d7 on the other, d1 to d6and so on? Please, try again later.
