"Níngún otro PC portátil puede hacer esta afirmación". Con 6.4 libras de peso (2,90 Kg), el Toshiba T1000 decía ser el PC portátil más ligero del mundo... hace 31 años. Tenía un procesador 80c88 a 4.77 MHz e incluía 512 KB de RAM, DOS 2.11 en ROM y un lector de diskettes de 3 1/2" y 720 KB. La pantalla era LCD monocromo, con una resolución de 640x200 píxeles (CGA) y un tamaño de 25x8,3 cm (algo menos de 7 pulgadas).

Digital Rainbow 100
El Rainbow 100 fue un ordenador creado por Digital Equipment Corporation (DEC) en 1982, con doble procesador: un Z80 que le permitía emplear el sistema operativo CP/M y un 8088 que le permitía utilizar MS-DOS o CP/M 86, además de tener un modo de "terminal" VT100 para conectarse a servidores VAX. El modelo 100A tenía 64 KB de RAM y el 100B tenía 128 KB. DEC ofrecía placas hija que permitían ampliar la memoria hasta en 768 KB más. Las disketteras usaban un formato propietario, que alcanzaba una capacidad de 400 KB. También se crearon interfaces de disco duro para él. ¡Ah! Y se puede ver uno en la recepción de los Ghostbusters (los originales, de 1984, el año de este anuncio).

Portátiles con pantalla de plasma
En julio de 1988, Toshiba anunciaba su gama de portátiles de esa época, desde un 8088 a 4.77MHz con una diskettera hasta un 80386, pasando por modelos con un 8086 con doble diskettera o disco duro y por un 286 con... "pantalla de gas plasma", unas deliciosas pantallas naranja que eran mucho más cómodas de leer que las "backlit LED" habituales de la época.

Obviously we believe in Strength In Numbers.
When it comes to portable PCs, we think that numbers should speak for themselves.
Perhaps that's why we have the largest number of high-powered, highly-portable PCs on the market today. All of which are IBM-compatible. All of which have industry-standard 3 1/2"disk drives, full function keyboards and a vast array of built-in ports. All squeezed into packages as easy to carry as a briefcase.
The T1000, for example, weighs a mere 6.4 pounds, yet boasts MS-DOS* in ROM, a 720KB 3 1/2 disk drive and an optional 768KB memory card which can be configured as EMS memory or a battery-backed RAM disk.
Our T1200H, on the other hand, has the distinction of packing a 20MB hard disk, a backlit screen and 1MB of RAM into a tidy 11-pound package We also make an economical dual floppy disk version known as theT1200F that weighs just under 10 pounds.
And thanks to rechargeable battery power, all three are ready to work wherever you go.
For even more computing power, the'T3100/20 is one of the smallest PCs with an 80286
microprocessor and an easy-to-read gas plasma display. It gives you a wealth of power and a 20MB hard disk in a trim 15-pound package.
Our T3200 goes even further, with two IBM-compatible internal expansion slots, a 40MB hard disk, an EGA plasma display system and up to 4MB of memory. Still, it only weighs a scant 19 pounds.
Finally, there's our powerful T5100, which at less than 15 pounds has all the best features of our other portables, plus an 80386 microprocessor for unmatched versatility and speed. And for a limited time, your T5100 purchase entitles you to buy Paradox 386,R Borland's powerful database software for only S299 {which is nearly $600off the retail price).

Intel 8088: Romper la barrera de los 8 bit sin arruinarse
Era octubre de 1981, hace nada menos que 35 años, e Intel anunciaba el 8088 como "la forma de romper la barrera de rendimiento de los 8 bits sin arruinarse". Comparaban su rendimiento (en pocos casos) con el de un Zilog Z80 y el de un MC6809, y también enfatizaban la capacidad de direccionamiento para 1 MB de memoria, la posibilidad de incorporar un coprocesador matemático 8087 y la compatibilidad total con su hermano mayor, el 8086, entre otras características. Además, su precio era cercano a los 14 US$ si se compraban en packs de 100 unidades.
