M1230 XA High Speed, 50MHz 68030 Acceleration, Hardware Floating Point, 32-bit Wide Memory Expansion (to 128 Megabytes), and Realtime Clock for the Amiga 1200 The MicroBotics M1230 XA is presented to Amiga 1200 owners as an extremely powerful, yet cost-effective, upgrade solution providing a high speed 68030 processor, a 68882 Floating Point Unit (FPU) and supporting the installation of up to 128 megabytes of 32-bit wide Amiga FastRAM. In addition, a high-accuracy, battery-backed realtime clock circuit is included. The M1230 XA board installs internally on the Amiga 1200's standard 150 pin bus expansion connector. M1230 XA speeds up general operations by as much as five times that of the native A1200. Using a single, 72-pin standard wide SIMM, as much as 128 megabytes of memory can be added to the A1200 (making it the biggest memory space available for the machine). The M1230 XA is delivered with a 50MHz 68030, making it absolutely the fastest '030 accelerator available as well. M1230 XA Specifications CPU Clock Speeds Supported: 50MHz 68030 installed as standard. M1230 XA is also available with either a 33MHz 68030 or 40MHz EC030 (EC=no MMU). FPU: Motorola 68882 math chip; PGA (Pin-Grid-Array) component. FPU can be matched to same-speed FPU or run at a different speed by resort to a separate oscillator. Target System: Amiga 1200 Personal Computer. Installation: Internal to Amiga 1200; resides on the 150-pin card edge connector. User or dealer installable. Compatibility: Designed for general compatibility with all Amiga system software; AmigaDOS system 3.0 and later. Memory Support: Supports the addition of a single, optional, 32 bit wide, 72-pin SIMM (Single Inline Memory Module). SIMMs are available in sizes from 1 megabyte up to 128 megabytes, single or double sided. This provision for industry standard SIMM support insures that the M1230 XA will always be useable with state-of-the-art memory technologies. M1230 XA provides the biggest memory space available on the Amiga 1200. Memory SIMM Types: 72-pin "wide-body" SIMM organized N-megabytes x 32 bits (the four megabyte SIMMs used in the Amiga 4000 and in MicroBotics' MBX 1200z are compatible with M1230 XA). Memory speeds from 40ns to 80ns are supported. The SIMMs used in the M1230 XA are available from numerous third party suppliers (i.e., they are not an expensive and limited proprietary SIMM-type). Typical name-brand SIMM: MT16D232 (eight megabytes) from Micron. SIMM socket is first-quality, professional metal-latch type for ease of insertion and secure contact with no breakage-prone plastic "ears". Realtime Clock Calendar: An Epson RTC 72421B clock/calendar backed by a long lasting, user replaceable lithium battery cell (CR 2032), is supported. System Compatibility and Mapping: RAM is autoconfigured under AmigaDOS 3.1 or software configured under 3.0. RAM can be withheld from the free memory list (for test purposes) via a jumper. RAM maps at hex-8 000 000 (and thus does not compete with PCMCIA peripherals). CPU and Math chip can operate without installed memory. The realtime clock is totally compatible with AmigaDOS; no additional software is required. Software: Includes MBRTest-2, a comprehensive diagnostic program for Amiga memory and SetXA, a configuration utility to read and write to M1230 XA's EEPROM. Applications: Useful in any speed, memory, and/or math intensive application such as animation, ray-tracing, morphing, scientific calculation, and image processing . Power Consumption: 600 milliamps (approximate). Configurations Available: Available with or without the 68882 installed, without memory or with any of the eight possible SIMM sizes. Product Availability: Worldwide distribution via Amiga dealers and distributors. USA Suggested Retail Prices: $399 (40MHz EC030); $429 (33MHz 68030); $499 (50MHz 68030). All units with realtime clock; memory and fpu at additional cost. Actual selling price determined by dealer.
