Since most modern computers do not have serial port connections you’ll likely need a USB to Serial adapter cable. If you want to make your own cables Mac GUI provides a guide for both the RS-422 mini-din-8 Male and RS-422 DE-9 Male (128k and 512k) to RS-232 DE-9 Female cable as part of his description for making various null-modem cables for his Macintosh 512. The cable is listed as a Apple IIgs, IIc+, LC III null modem (Figure 1).

I took the easy route and bought both the RS-422 mini-din-8 Male (Macintosh Plus or later) to RS-232 DE-9 Female (PC) cable and USB to RS-232 from RetroFloppy. you can’t connect to the internet through this, but you can use this method to copy files to and from your Modern System running Basilisk II and your 68k Macintosh.

I don’t have a modern Macintosh, so I can only describe how to a modern Windows 10 PC with Basilisk II connect to a 68k Macintosh via a USB to Serial connection. ZTerm 1.0.1 is included on my System 7.5.5 drive and partition images in the network folder ZTerm 1.0.1 by David Alverson running both in Basilisk II and on your 68k Macintosh.Basilisk II setup for a serial port connection running booting from one of my System 7.5.5 drive or partition images.A USB/Serial null modem cable, you can make one, or simply buy the null modem cable and a USB to Serial Adapter.A modern system capable running Basilisk II and a 68k Macintosh running System 3.x or higher with 512k of ram or greater.If anyone has a IIfx or Centris/Quadra I’d be curious to find out if you can hit the 230.4kbit/s as a transfer rate.

2Mbps (256KB/s) for Centris/Quadra AV systems with Direct Memory Access (DMA) serial ports (GeoPorts)Īccording to Window’s Device Manager the max speed for my USB to serial adapter is 921.6kbit/s (115.2KB/s), about the same as the Macintosh IOP ports, but Zterm 1.01 has a max data rate of 230.4kbit/s (28.8KB/s).900 kbit/s (112.5KB/s) for the IIfx, Quadra 900, and Quadra 950 thanks to there Input/output processor (IOP) ports.57.6 kbit/s (7.2KB/s) on all other pre-PPC Macs except IIfx and Centris/Quadra AV that have IOP ports.From what I’ve read on Low End Mac and MacWorld ( April 1996 page 47), the connection speed limits for this method are likely: This guide describes how to use Zterm with a null modem connection, instead of using a real modem, to connect Basilisk II to real Macintosh and use X/Y/ZModem as the communication protocol over that link. For larger files I use Basilisk II to edit my drive images. One of the methods I tried, and the one I use the most, is transferring small files from Basilisk II to my 68k Macintosh. About a year ago I purchased a null modem (serial) cable to let me connect my Apple IIe Card enabled LC 475 to my Apple IIc, and decided I should also test it out as a way to transfer files between my Windows 10 PC (should also work with OSX and Linux) and my Macintosh Plus, it was actually fairly easy.
