Wanted : Pinouts for 9311, 93L14, 8273 chips

by mstein＠crestline.ca

----------------------Original Message------------------------ One question. Assuming the signal names are conventional, that's the same pinout as the '154 decoder. And yet my (ancient, hardbacked) TI TTL book says that while the 74154 is a logical replacement, it's not a direct replacement (this implies to me a different pinout). One of the pinouts I received had the A inputs in the oposite order (20 = A0 .. 23 = A3). Can somebody please check which is correct. -tony ------------------------------------------------------------------------ Well, you'll probably get another dozen replies from the other helpful folks here, but the pinouts and logic tables are identical and 23=a0, 20=a3. I thought the same when I looked at the 9311, that it sure looked like a 74154 which was used everywhere, and that there must be a pinout or big characteristic difference to make it worth FSC's while (since they also made the '154, and TI, NSC and Motorola, who also made the 9311). But the only difference I can see is that the max propagation delay is less on the 9311; maybe someone else will see something else. mike

Core memory speeds

by bfranchuk＠jetnet.ab.ca

Since I am building a classic TTL style computer, what was the access and cycle time of core memory before it vanished and just when did it do that? Also when did 74LS come out? I am aiming for late 70's early 80's time frame here since this looks to be the transition stage from the the old to the new. Ben

Amstrad PPC640 part 2 (bootdisk)

by 3sdiarftt02＠sneakemail.com

Thanks for the help with the power supply for the Amstrad. I've picked up a nice unit that, while heavy, appears to be made for the computer it's so perfectly matched. Was that plug, that polarity, that voltage and that current a fairly common choice for a while? Anyway, I made a boot disk using Win98SE and the Amstrad really doesn't like it (can't blame it) -- crashes on boot. Can anyone supply an image of a boot disk known to work on the Amstrad? krishaven *aT* spamcop *dOt* net. TIA. BTW: It complains about setting the time and a dead battery before looking for a system disk. Does anyone know if its expecting me to buy 10 C cell batteries or if it's referring to an internal battery of some kind?

VMS command question and help, off-topic

by freddy＠kotelna.sk

Hello VMS folks, just a very simple question, what does a command like this do: BACKUP MULTIA_V72.BCK/SAVE DVA0:/IMAGE/VERIFY (it's alpha vms, so not sure whether floppy is named DVA0: on VAXen, too). I know basicaly what this does, my question is whether the .BCK file has some special format or whether UNIX command like this: $ cat MULTIA_V72.BCK > /dev/diskette0 or $ dd if=MULTIA_V72.BCK of=/dev/diskette0 is equivalent. If it's some special format, were it possible that you issue this command for me on some VMS and grab the diskette raw file and make it available for me? the image is available at http://www.kotelna.sk/freddy/multia_v72.bck (1419264 bytes). Cheers, -- freddy ...for more info 'finger freddy(a)kotol.kotelna.sk'

SGI Discussions? was Re: Mac SE/30 accessories availability?

You might be able to get a non-optical mouse from an Indigo or something of that vintage and change the plug, or make an adaptor. AFAIK, the Sun optical mice were made by Mouse Systems, and so were the older SGI mice. The 4DFAQ (aka "This Old SGI") has some instructions to convert a Sun mouse for an SGI. I'm not sure what effect the modification has; it could be baud rate. The Sun mice are 1200 baud, while SGI's were 4800 baud, and of course Sun use 0V/+5V while SGI used +/- 5V (roughly, it's more-or-less RS423 levels). There are also different protocols; SGIs use 5 bytes, and I think Mouse Systems standard mice used 3. Dunno about Suns. Another thing you might look out for is an older Sun non-optical mouse. I used to hate the optical ones (because of the limitations of the pad) and was delighted to find that Sun made an alternative, around the time of the early Ultras and later Sparcstations. -- Pete Peter Turnbull Network Manager University of York
