There is no need for left-right scrolling, with portions of the display off the screen. The new, 7" amber display is a big improvement over the 5" monitor on the Osborne 1. The top 6K is unused, but overlays memory along with the rest of the bank. Above this is 4K of ROM which is unused address space. When a write is performed, the bottom 4K is RAM, containing the two character sets. For example, when the CPU performs a read, Bank 8 contains 8K of ROM in the lower portion and 2K, as temporary storage, above it.

The upper portion contains the attribute bits, which control display type (reverse or normal, full or half-intensity, underscore, and the alternate character set).īank 8 is 16K, and is organized differently depending on whether the CPU is reading or writing to it. The lower area contains bits 0 through 7 of the video memory and an area reserved for the Monitor and the DMA port. With sufficient hardware and a different memory scheme, up to 32 use banks are available.īank 7 contains the video screen image. The top 4K controls bank switching and data handling, and therefore is never shadowed by any other bank.īank 1 consists of 60K RAM and Page Zero, which contains critical system address pointers.īanks 2 through 6 are not implemented, but are reserved for system expansion. It also contains BIOS, a part of BDOS, and disk and interrupt buffers. Banks can consist of RAM, ROM, or a combination.īank 0 consists of 64K of RAM reserved for system use. This is done by bringing in memory segments as needed and hiding parts not used. By organizing memory into banks, the CPU can address more memory than would otherwise be available. A bank is simply a range of addresses in memory. I would have predicted that the keyboard would have been the first thing that Osborne would change. It still offers plenty of key bounce and an odd feeling. Unfortunately, the keyboard feel hasn't been changed from that of the Osborne 1. The detached keyboard has 69 keys and a 12-key numeric keypad. The power switch has been moved to the front, just under the screen.

Two RS-232 serial ports, an IEEE 488 parallel port, an external video connector, and a composite video connector are located on the front panel. The drives are now placed to the left of the video display. The most noticeable improvements are a 7" amber display, which is easier on the eyes than the old 5" black and white screen, and two double density disk drives with 185K capacity each. Additional RAM includes 4K for two 128-character sets, 4K X 12 bit RAM for video memory, and 2K for scratchpad RAM. SpecificationsĪs with Osborne 1, a Z80 microprocessor is standard, allowing access to the large library of CP/M software. But the Executive does offer a refinement of existing ideas and technology. As with the Osborne 1, there are no real technological breakthroughs.

The result is a better computer, added features, more intelligent design, and improved software and documentation. The new line is the Osborne Executive series.

In an effort to keep and expand its market share, Osborne has introduced a new generation of portable computers. Kaypro, Compaq, and other manufacturers began bundling portable computers with software for sale to a lucrative and previously overlooked market. WordStar, MailMerge, SuperCalc, CP/M, and utilities that cost almost as much as the computer were thrown in for free. Also included in the package was enough software to get the user up and running. The sewing-machine-like case opened up to reveal a self-contained computer with a small, monochrome display, two disk drives, and 64K of memory. In 1980 Adam Osborne started an avalanche in personal computing with the introduction of the Osborne 1 Portable computer.
