Author	Topic
llamaboy487 Full Member USA 516 Posts	Posted - 08 Apr 2003 : 20:04:37 anybody know where i might find one or two 8080a's to use in my Altair-based homebrew computer? I was planning on using the Z80 but i really dont want to because that would mean redesigning the cpu module of the Altair and im not entirely sure how to go about doing that... ...money isnt really too much of an issue here, i have lots of birthday money to burn ------------- Grand Leader, Apple /// Revolutionary Council Apple ///'s Liberated: 29477 Visit http://www.kevcave.tk (my Forum) ...because no one expects the Spanish Inquisition!
G4from128k Full Member USA 873 Posts	Posted - 08 Apr 2003 : 20:11:18 Back in the late 70s, you could buy 8080As at Radio Shack right off the components rack. Otherwise, I am clueless. If you could use a Z8 (a newer embedded processor version of the z80), you could take apart a payphone. I saw the inside of one recently and it had a Z8 MPU. Good luck.

It was a full-sized outdoor Qwest payphone with blue-green fluorescent display (probably about 15 x 3 characters). Is the Z8 at all compatible with your design?

llamaboy487 Full Member USA 516 Posts	Posted - 09 Apr 2003 : 11:11:40 yep, the amd r8080a is exactly what i need, but my PAF doesn't allow for eBay (dont ask, long story) so unless i REALLY beg that wont happen and i wouldn't need to rip the z8 out of a payphone, i'd just buy one for three bucks from http://www.jdr.com (easier to buy one than try to break into a payfone, trust me... the first things i built when i got my soldering iron were phreak boxes) unless... maybe theres a schematic online for a Z80 replacement for the 8080a cpu board in the altair, but if there is its sure not on google... I've also found the 6800 and all of its support chips for reasonable prices... so why is the 8080a the only late 70's processor not still in production? i could use a 6502, 6800, Z80, anything else easily but the one i need (want?) is NOWHERE... any suggestions? ------------- Grand Leader, Apple /// Revolutionary Council Apple ///'s Liberated: 513511 Visit http://www.kevcave.tk (my Forum) ...because no one expects the Spanish Inquisition!

Alien Junior Member Netherlands 269 Posts	Posted - 10 Apr 2003 : 01:53:52 Good. I checked, and I don't have any 8080's. I do have a stack of 6802's, though. ,xtG .tsooJ -- who \| grep -i blonde \| date cd ~; unzip; touch; strip; finger mount; gasp; yes; uptime; umount sleep

Mmm, that explains the funny modem-like noises you get when you call modern payphones. I wonder if there's a way to bypass this and get them to ring? There must be a way, as that is what the phone company does when they ring it. BTW, where did you get this payphone? I'd just die if I had one of these! quote: oops, I just blew an 8080a up the other day with some old fireworks. It was a pull from an IBM piece of crap.

Official 68k videographer Official MLA TourGuide It looks, goes, and handles nothing like a tank, but they last for a loooooooooooooooooooooooooooooooooooooooooooooooooooong time. Our old 1983 WB Holden ute is still running fine, apart from the dodgy Pioneer "stereo" that Dad put in before i was even born....a lot of Falcons from that era are slowly starting to bite the dust. -------------------------- Give your dreams a chance.™ - Apple in the mid '90s Warrior maclover5 68k Macintosh Liberation Army Number of 68ks Liberated: 7 Number of Contraband (PPC) Liberated from the Dumpster: 1
