1978年出现的品牌并不是很多。可能是因为市场接近饱和。主要型号有：
ibm5110。是5100的发展。
这一款1978年生产的Exidy Sorcerer计算机最大的特点是第一次使用了只读存储卡。为以后的各种存储卡，包括数字相机等等的发展提供了前提。

详解编辑本段回目录
Before the Sorcerer computer, Exidy Inc. was a leading manufacturer of home and arcade video games. They decided that they had the knowledge and expertise to design and market a home computer.
The Sorcerer seems to have been more popular in Europe than in the U.S. - CompuData distributed the Sorcerer in Europe while Exidy sold them in the U.S.
After Exidy went bankrupt, CompuData, which had changed its name to Tulip Computers, took-over and continued marketing the Sorcerer in Europe. I think this is when the keys turned from light to dark!
There is also a computer known as the "Dynasty smart-ALEC" - this is really just an Exidy Sorcerer licenced by Dynasty Computer Corp. of Dallas, Texas. It also has the dark keys as seen above.
The Sorcerer has no built-in programming language other than the 'monitor', which provides access to memory for dumping or changing memory locations. There are also commands for reading and writing to either of the tape interfaces, and even tapes written by BASIC can be loaded from the monitor.
All other programs and languages are loaded from either a cassette tape, or a cartridge (ROM-Pac) plugged into the right side of the console. These ROM-Pacs are real, authentic, 8-track tape cartridges with a computer circuit-board inside instead of a music tape. The Sorcerer is the first computer to use ROM cartridges for instant program loading and access!
There are actually at least two version of the Sorcerer. The original motherboard (model DP1000-1) had hardware issues with the RS232 serial communications, according to
The model DP1000-4 is the "Dynasty Smart-ALEC", a rebadged Sorcerer.
Above: The original Exidy Sorcerer motherboard.
Above: The redesigned Exidy Sorcerer II motherboard.
If the standard Sorcerer wasn't enough for you, the could purchase the S-100 Expansion Unit ($419), allowing you to utilize any of the hundreds of S-100 cards on the market. The S-100 bus was very popular in the late 70's - many of the earliest computers used it exclusively.
There isn't much inside of the Exidy S-100 chasis, just a power supply and six S-100 expansion slots, but this is all there is to any S-100 computer - all of the logic and circuitry are on the S-100 cards which plug into the slots.
Although any 'composite video' monitor can be used, the Exidy "Video/Disk" ($2995) offers that professional touch. It contains a 12-inch video display and dual mini-floppy disk drives with data storage capacity of 630K words.
