original date 04/09/87. I found a blue MAYNARD SURPRISE! in my parts box recently and could not figure out what it was. now i know. SURPRISE! accelerator card doubles the speed of your MS/PC-DOS PC/XT/clone to 9.54 Mhz (registers 2.6 times as fast as an IBM PC on Norton's SI index). Turbo your portable! Does NOT require an expansion slot. Unlike the Fast 88 accelerator board, the SURPRISE! does not run off the 8284 clock chip slot. By running off the 8088 chip slot instead, hardware compatibility problems are eliminated. (No soldering!) If you already have one installed, your 5Mhz math co-processor is compatible with the SURPRISE! -- no need to upgrade to an expensive 8Mhz 8087-2 chip. Dual speed (9.54 and 4.77 Mhz ensures maximum software compatibility. Includes DOS accelerator software and Maynard Electronics' ** 5 year ** warranty. $150 ($250 list) A $30 extension cable may be necessary on some clones (especially Compaq). SURPRISE! 286 board effectively converts your PC, XT, or clone to an AT clone. Using an AT 80286 processor it boosts your machine's speed up to six times (registers 6.6 times as fast as an IBM PC on Norton's SI index). It takes up only 1/2 expansion slot ('short card'), has no wait states, and is EGA, EMS, and LAN compatible. An 8K memory cache is included on the board. Its dual speed design insures maximum software compatibility. It will also accept an optional 5Mhz or 8Mhz math co-processor (80287-3 or 80287-8). It can be installed in any expansion slot, including #8. DOS accelerator software is included, which further increases speed of screen writes, keyboard reads, and disk read/writes. It comes with Maynard Electronics' ** 5 year warranty **. $499 ($599 list). A $40 extention cable may be necessary on some clones (especially Compaq).
