Encarnado disse:À frente diz o modelo (isto nos Macs pré G3 B&W).
Exemplos:
Power Macintosh G3/266
Power Macintosh 7500/100
Power Macintosh 9500/180MP
Macintosh Performa 5200
Macintosh Quadra 650
Macintosh IIfx
God_Lx disse:Axo k só acertaste no MacOS... LOL O CPU provavelmente também, mas o disco é maiorzito, e axo k tem 64mb de ram...
Na frente da caixa diz mesmo Performa 630
bsod disse:o unico dessa lista ke tenho é o 5200... mas tu n tens dois ke eu tenho... eu tenho dois SE/30 e um IIci
ah e o IIci tem um upgrade card ke o acelera mais ke o teu IIfx... acelera a 50 Mhz (viva, grande speed... )... se calhar vou experimentar correr OS 8 nele c o Born Again... mas primeiro tenho d esperar pela board nova (a ke tinha deu o berro )
bsod disse:yah... o disco do meu anda esquisitóide... o problema do video... vai mudando do magenta pa ciano, pa amarelo, e dps estabiliza... o ke eu keria era RAM, ROM, e uma placa TV... (quero lá saber do disco! arranco de CD )
2 SE/30 - um funciona lindamente (ate tem a bateria PRAM direitinha), tirando alguma corrosão nas roms ke o faz aparecer de vez em quando às riscas quando boota (desligo e volto a ligar, e lá arranca) e o altifalante quase dead (mas uso speakers externos ). o outro arranca, mas o vídeo está uma desgraça - a única coisa ke aparece é uma risca vertical no centro do ecrã (amplificador horiz estoirado...) - esta pa peças, se o outro decidir morrer... . O IIci está à espera d uma board nova... vem da Bélgica . Depois ponho-lhe ali uns 32 Mb d RAM, uma cache card c CPU d 50 Mhz, um disquinho jeitoso, CD SCSI externo, monitor d 15'' e ligação à net por rede e dps é ke falamos...
Wikipedia disse:NuBus is a 32-bit parallel computer bus, originally developed at MIT as a part of the NuMachine workstation project, and eventually used by Apple Computer and NeXT Computer. It is no longer widely used.
In order to select the proper device driver, NuBus included an ID scheme that allowed the cards to identify themselves to the host computer during startup. This meant that the user didn't have to configure the system, the bane of bus systems up to that point. For instance, with ISA the driver has to be configured not only for the card, but for any memory it needs, the interrupts it uses, and so on. NuBus required no such configuration, making it one of the first examples of plug-and-play architecture.
NuMachine was never released, but Texas Instruments later took over the NuBus work in 1980 and standardized it as IEEE 1196. This version used a standard 96-pin three-row connector, commonly found on other bus systems like VME and PCI, running the system on a 10 MHz clock for a maximum burst throughput of 40 MB/s and average speeds of 10 to 20 MB/s. A later addition, NuBus90, bumped the clock rate to 20 MHz for better throughput, burst increasing to about 70 MB/s, and average to about 30 MB/s.
NuBus was later selected by Apple Computer for use in their Macintosh II project, where its plug-n-play nature fit well with the Mac philosophy of ease-of-use. It was used in most of their Mac line through the late 1980s and into the 1990s, and was upgraded to NuBus90 starting with the Macintosh Quadras. Early Quadras only supported the 20 MHz rate when two cards were talking to each other, since the motherboard controller was not upgraded. This was later addressed in the 660av and 840av models, and used on the early PowerMac models. Apple's implementation also supplied an always-on +5v "trickle" power supply for tasks such as watching the phone line while the computer was turned off. This was apparently part of an unapproved NuBus standard.
