The Commodore 128D is the latest of the original Commodore 8-bit line to be produced. This is THE all-in one power machine for the Commodore 64/128 enthusiast, includes all the basics in a compact steel case along with the bug-free BASIC ROMS and 64K VDC RAM memory.

From playing popular Commoore 64 games to using the advanced 128 mode programs - the 128D makes it more convenient.

• Internal 1571 - 5.25" Disk Drive Disk drive capable of reading Commodore 4040/2031, 1540/1541 and double sided 1571 disks. As well as read/write CP/M and MS-DOS 5.25" disks (up to 360K with CP/M or other utilities)
• 40 (VIC-II) or 80 Column (RGBI) Video - cabable of stunning hi res graphics.
• 64 K Video memory for 80 column display (increases the versatility of the 80 column mode graphics)
• 128 K of built-in system RAM - readily available in 128/CP/M mode and accessible via ML in 64 mode.
• Dual processors, A 2mghz 6510 compatible 8502 processor and a 2mghz Z80 processor
• Detached 92 Key extended keyboard includes a separate numeric keypad.
• The versatile SID sound synthesizer chip that made the Commodore 64s beautiful sounds.
• Internal Heavy Duty Power Supply - beefy enough to handle REUs or the Super CPU and no external "power brick" to trip over under the desk!

• Commodore 64 Mode - Play all of your Commodore 64 games and other software (99.9% Commodore 64 compatible)
• Commodore 128 Mode - Advanced BASIC 7.0 - All the goodness of BASIC 2.0 plus the graphics commands of the Super-expander/Basic 3.5, 4.0 BASIC Disk commands, structured BASIC statements, SID sound and sprite animation commands, Built-in 8502 ML Assembler/Monitor as well as extended memory management commands.
• C128-Burst Mode fast disk access when used with 1571, 1581 and CMD HDs.
• CP/M Mode - which allows the 128 to run the vast library of professional and business CP/M programs like Wordstar, dBase and others.

The 1764 allows the Commodore 64 (or 128) to access 256K more RAM, either through bank switching with the right software (instructions and example programs are in the manual and disk) or can be set-up as a RAM drive with the included RAMDOS on the utility diskette.

The 1764 REU is well supported in a number of advanced 64 programs, GEOS which can use the REU as a high-speed temporary storage, Maverik Disk Copier which can enable the 64 to copy an entire 1541 in one pass. Of like the Super Snapshot (V5) which can allow you to freeze and swap between multiple Commodore 64 sessions (requires the Super Snapshot cartridge and a comaptible multi-port expansion unit). There are other terminal and Word processing programs that utilize the extended capacity of the 1764. BBS Systems greatly benefit from a RAM DOS like the 1764 as they could swap in and out programs in an instant compared to using a standard drive (1764 is compatible with Image BBS and others, check your BBS documentation).

The example programs on the disk and guide illustrate how to use the 64 in your own programms either to swap in and out memory (a high res animation is one example supplied) or to use it as a fast 256K RAM disk storage.

Included with the 1764 is a heavy duty power supply powerful enough to heasily handle the 1764 REU as well as just about any other energy hungry peripheral you add to the 64 (such as a SuperCPU).

The 1764 can be upgraded to 512K (like the 1750) by soldering in 8 additional 256kx1 DRAMs and cutting a trace on the circuit board - or up to 2MB with more involved electronics work.
