PowerMac 7100


This group of machines are the least upgradeable of the PowerPC Macs. The 6100 was the first PowerPC Mac, with an astonishing (for the time) 66MHz clock speed. It was introduced in March 1994.

The 61/71/8100's use NuBus as their internal expansion (cream sockets evenly interspersed with holes) which was supposed to be the next big thing - unfortunately it was not - this leaves these machines at a disadvantage because modern expansion cards use PCI slots.

These PowerMacs use SCSI for internal storage devices, not IDE which is used by most modern personal computers.

Ethernet connectivity is provided via the now obsolete AAUI port.

How to Identify these Machines

These PowerMac machines are easily identifiable.

The PowerMac 6100 came in a small form factor (thin) desktop case with the floppy and CD-ROM drives on the same level.

The PowerMac 7100 came in a normal height desktop case. The 7100 is identified by the number of bays on the front. The 7100 has a floppy drive situated to the top left and a CD-ROM bay / CD-ROM underneath there are no other slots on the front.

The PowerMac 8100 came in a tower case ,the same case as the PowerMac 8200, and this case needs to be removed to identify between them. The case is removed with screws on the back and the case pulls forward. Turning the machine onto its side will reveal cream coloured slots. If your machine has 3 long slots divided into 2 parts then you have a PowerMac 8200. If the sockets are equally interspersed with holes then you have an 8100.

If you are still unsure you can contact us on 01223 833 412 or by email for confirmation. If you want to upgrade but aren't happy to install your upgrades then we can help. Simply ask our engineers for further details.

Memory Upgrades

The 61/71/8100 PowerMacs use 72 pin SIMM memory sticks. These memory chips are now very difficult to source. At present we are unable to supply these chips. We suggest maybe eBay as a source. It is best to get memory which has come from a previous machine of the same type due to variations in memory access speed.

We do not have RAM available for these Macs.

CD/DVD/Blu-ray Drive Upgrades

The PowerMac 61/71/8100 Machines use SCSI as their internal storage devices. SCSI has now been superseded by IDE for internal optical drives. As the these machines also do not have PCI slots (and so cannot be upgraded with a modern connection type) there are no current optical drive upgrades for these machines.

There are no optical drive upgrades available for these Macs

Internal Hard Drive & SSD Upgrades

The PowerMac 61/71/8100 Machines use SCSI as their internal system bus. SCSI has now been superseded by IDE for internal hard drives drives. As the these machines do not have IDE or PCI slots there are no current hard drive upgrades for these machines.
