Also Later LC IIIвЂ™s with the manual floppy drive eject are more likely to be the plus models though be aware this isnвЂ™t a sure thing.ДЈ) FPU вЂ“ Finally we have a socket to add an optional 68882 math coprocessor to assist in complicated math calculations. There are guides available on modding the LC III into an LC III+ but perform at your own risk.

Only opening the case and checking the CPU or powering the machine up and checking in software would reveal the difference. There is no way to tell the two models apart as there was no indication given on the outer case. There is also a version of the LC III known as the LC III+ which is identical save for the CPU which got a speed bump up to 33mhz. Some benchmarks of the time placed the LC III twice as fast as the LC II in overall performance. The CPU in the LC III is a Motorola 68030 running at 25mhz, also a bump up from the 16mhz of the previous LCвЂ™s.

Unfortunately these 32-bit cards are quite uncommon.Дў) CPU вЂ“ The LC III unlike the LC I & II now uses a full 32-bit data bus as opposed to a 16-bit but so the CPU can be taken full advantage of. The вЂњenhanced LC PDS slotвЂќ in the LC III supports both 16-bit PDS cards of the type that would be used in the older LC machines but also 25mhz 32-bit PDS cards. Mine came with a standard 80mb SCSI hard drive but I upgraded mine to a 500mb model by transferring the upgraded hard drive from my LC II.ДЎ) Enhanced LC PDS slot вЂ“ The PDS slot on the LC has a slight extension to it compared to the PDS slot in the LC and LC II. The general layout is basically the same as it was in the LC II with a single floppy drive and space for a SCSI hard drive. Opening the LC II is exactly the same as the other LCвЂ™s with just two fairly sturdy tabs securing the top. The LC III like the LC I & II does not support power on via the keyboard and use of the rear switch is required. The Ethernet card installed on the right is the same one that used to be installed in my LC II.

from left to right you have the power connector and switch, Mac video port, modem and printer ports, external SCSI port, ADB port and finally an audio jack for speakers and mic. The rear of the case though is identical to the LC I & II. These cases also have the case badge as more of a label then etched onto the case. bear in mind there are two versions of the LC III case and one features a manual eject floppy drive that looks a little different with an indentation to grasp the disk. Other then the LC III badge the case is identical to the LC I and II. There is now a MMU as there was built into the LC II but also much more expandability for RAM as well as a socket for a FPU chip and the video memory supports 640 x 480 resolution without any kind of fiddling or upgrade. Finally we have a full 32-bit data bus so as not to strangle the 32-bit CPU. Thankfully the LC III finally addressed all the above issues while maintaining the same small form case.

The LC II added the ability to use virtual memory via the CPUвЂ™s built in MMU and tweaked the video a bit but was otherwise identical. The main compromises of the original LC and following LC II wereДЎ вЂ“ A 32-bit CPU on a 16-bit motherboard severely hampering the performance of the LCs 16mhz 68020 CPU.Дў вЂ“ An imposed limit of 10MB of RAM regardless of the size of the RAM stick(s) installed.ДЈ вЂ“ complete lack of a MMU or FPU socket on the motherboard.Д¤ вЂ“ Difficulty getting the LC to run with monitors outside of the fixed resolution 512Г—386 monitor it was intended to be paired with or period Apple or early VGA monitors.

Both machines more or less accomplish what they set out to do but also both were heavily compromised in functionality to achieve this end. In previous articles we covered both the nearly identical LC and the LC II, both of which were early attempts to bring an affordable color Macintosh to the market.
