1998 – This is a long post, but it is relevant to many of the problems we have discussed recently. I would also be interested to know if people agree with what this Apple tech has to say.

1998 – Your results may vary, but this should provide a good starting point for tweaking serial throughput on your Mac setup. Note that FreePPP allows serial port settings of 115.2 kbps and 230.4 kbps, settings not possible with Apple’s serial toolbox routines. This follows up on our earlier article, Macintosh Serial Throughput, providing real […]
1998 – The entire idea of a LocalTalk gateway is to bridge LocalTalk devices that don’t have ethernet – such as Macs, early LaserWriters, other printers, etc. which are not TCP/IP devices (visible on the Internet in the Internet’s most common language) as LocalTalk devices.
1998 – Much of the following information has been distilled from a series of articles by Steve Gibson of SpinRite. Since these articles specifically address Click of Death (COD) tools in the Windows world, they provide excellent technical information but no Macintosh perspective. If you want to know more about COD, Gibson’s articles are the […]
1998 – Scott Barber blew me away with the news: He has Mac OS 8.1 running on a Macintosh IIsi!
“You can’t run a 9600 modem on a Plus.” “You’re wasting your money buying a 56k modem for that old Centris 610.” “Those old Macs don’t do handshaking.”
Sometimes getting a SCSI chain working properly seems to be more hit and miss than science. We know the last device should be terminated, that the chain should not exceed a certain length, and that every device must have a unique ID. But even that isn’t enough to consistently build a busy SCSI chain and […]
1998 – There are several variables that determine hard drive throughput: How fast your Mac can move data over the SCSI or IDE bus, how fast your drive can move data over the drive bus, and caching, including both disk caching by your Mac and the disk’s internal data buffer.
Apple popularized SCSI (small computer system interface) by making it a standard feature on the third Macintosh, the Mac Plus, which was introduced in January 1986. Although Apple only embraced a subset of the emerging SCSI standard, the new bus allowed chaining up to seven peripherals to the computer. The 8-bit parallel interface was theoretically […]
This information is about what are commonly referred to as the x200 series of Performas and Power Macs. These machines, with the exception of the Performa 6360, were all PowerPC 603 or 603e machines with severe hardware problems.
It is out of sheer desire to help others overcome the year-long disaster that I went through, that I would like someone to be able to document this somewhere. Please take note, this affects all Centris 610 and Quadra 610 machines, but not the 660av.
1997 – Surprising to many, the first Macs didn’t have SCSI. The Apple design team created a compact, closed box with a disk drive, CPU, monitor, 128 KB of RAM, keyboard and mouse ports, a floppy drive port, and two serial ports. The serial ports were the secret – they could support a 230.4 Kbps […]
