|
||
The SX500 was an Amiga 500 cased into a SX64 chassis.
|
||
|
||
Only a few prototypes were made, although the machines creator has 1 of them, often shown at Computer shows over in the states. It used the same case, as you can see where the top cartridge slot has been blocked off!
|
||
|
||
About the SX-500, **Bob Eller** adds:\
|
||
Your SX-500 picture is a one of a kind computer built by Dale Luck, who was with the Amiga Los Gatos engineering team. As I understand it, he wanted a portable Amiga and put the machine in a gutted SX-64 case.

|
||
The SuperCPU by Creative Micro Devices is an accelerator cartridge for the Commodore 64. It contains an W65C816S processor running at 20 MHz, providing 20 times the performance of the stock 6510 processor! CMD later added a SuperRAM Card option that could include up to 16 MB of additional memory. There is also a v2 version that offers native 128 mode support (also called SuperCPU/128). It is one of the most sought-after Commodore peripherals.

|

This RAM expansion unit by Creative Micro Devices was intended to be used as a RAM drive to accelerate disk access. It is externally powered, and thus will preserve the data even when the computer is turned off.

|

|
||
**Cheaper and faster than diskettes.**
|
||
|
||
This Quick Data Drive from Dean Electronics is dedicated to Commodore 64 and <$252$>Vic 20 systems. It uses a special tape called 'Wafer', of 16, 64 or 128 Kb capacity. This wafer was also used by a product marketed for the <$223$>Sinclair Spectrum, called Wafadrive. Various tests proved that the Q.D.D. was approximately 20 times faster than a normal cassette recorder and 2 or 3 times faster than the Commodore 1541 disk drive. The reason : data transfer routines (called QOS) much more efficient than those of Commodore, and a file management operating system (FMU) much more modern and powerful.
|
||
|
||
The Q.D.D. is however not more than an advanced tape recorder using a magnetic tape, and the delay to access a specific file still remains higher than with a normal disk drive. Despite its qualities, the Q.D.D. did not meet success because most C64 software was sold on disks or tapes and users had to acquire both Commodore peripherals before investing in a third powerful storage system.

Emulators realy make me chew my fingernails, I had to buy my own copy of windows for my computer and I do NOT want to have to wipe the windows partition of my Mac... That would be $200 and 4 months of mowing lawns, shoveling leaves and blowing snow down the so very unforgiving drain. :(\
|
||
Back to the point can any of you fellow computer nerds help me find an emulator that I KNOW I can trust? I need it to be small because I have the "You are running out of disk space, click on this message to have windows $ the presious non-replaceable files you collected over a period of 1 year" message popping up whenever I start Windows. All sugestions are welcome, Thanks! (sorry i ramble sometimes)

(Sigh!) I was lucky enough to own an SX-64 back when the Commodore 64 was still very popular. With a bit of skill, the SX-64 could be nicely modified into a dream machine that caught everyone's attention at computer user group meetings.
|
||
|
||
First, I remember that there was a commercial hardware product called the SX-Flash, which was a truely transparant speed-up mod that worked with all games, plus added some nice fast dos commands (fast load cartridges were good, but they didn't work with some copy protected games).
|
||
|
||
Second, there were some great home-grown modifications that could be done, with nice places to hide the switches. We added a drive number selector switch so that the built in drive could be device 8 or 9, complete with an LED number display mounted flush right next to the drive in the area between the drive and monitor.
|
||
|
||
We also added a write-protect always on/off toggle switch for the drive and mounted a flush red/green LED in the same area. (This was specifically for one guy in the user's group who had a bad habit of not keeping the source & destination drives straight and copying his blanks onto others' software disks.)
|
||
|
||
I was software librarian and finally found an SFD Dual Drive. This was one of the best drives ever made for the C-64 family and it made the SX-64 the perfect portable disk duplicator for club meetings.

My first computer was an SX-64 as shown on the exhibit page. Rare as they go, mine was even rigged by the danish branch of Commodore to have danish letters (Æ/æ, Ø/ø and Å/å) on both keyboard and on screen.
|
||
|
||
Here are a few tips about it:
|
||
|
||
The floppy drive on the executive will work on pretty much any 5.25" floppies that you can get hold of. For info on using the machine and it's built-in Basic and OS, search the Net for info on the Commodore 64. There's both the user manual and the in-depth "Programmer's Reference Guide" - read these as if you had a "regular" Commodore 64 rigged up with a 1541 floppy disk drive and a monitor. The only things that don't apply to the Executive, is the use of the "Datasette" and casette tape storage.
|
||
|
||
Beware of expansions that go into the "User Port" at the rear of this machine. In at least the SX, one side of the 9 V AC available at the user port is connected to the DC ground, whereas in the Commodore 64, the same 9 V AC supply is electrically "floating" relative to the DC.\
|
||
So things like e.g. RS232 interfaces, designed for the user port on a Commodore 64, might fry either itself or the (supposedly compatible) machine if plugged into an Executive 64...
|
||
|
||
About the keyboard cable: Allthough the connectors in the keyboard and on the main unit may look like standard DB25 females, they are not - at least the spacing between the two rows of pins are narrower than standard.\
|
||
In case you consider replacing the connectors with standard DB-25's and soldering your own keyboard cable: I'm not perfectly sure about it, but as far as I recall from hunting down a "flaky" connection in my cable, most (if not all) of the wires go straght through, from pin #n on the keyboard, to the same pin #n at the main unit (numbering just as if they were DB-25's).

The SX/DX 64 is the "laptop version" (though hardly portable) of the [C64](/museum/commodore-c64/). This computer has a built-in 5" color screen (just about enough for the eyes), a detachable keyboard with new functions, and one or two 5.25" floppy disk drives (the famous 1541), depending on the model.
|
||
|
||
The DX-64 and the SX-100 (SX-64 with black & white monitor) were first announced in January 1983 but the SX-100 never made it to the shelves and was replaced by the SX-64 later that year.
|
||
|
||
One important feature is that the SX/DX-64 lacks a cassette interface ! People who upgraded from the classic C64 couldn't play their games stored on tapes ! Some programs that used the tape buffer for storage (of sprites say) had problems too.\
|
||
The cartridge slot is found on top of the case, and there is a sound speaker inside the unit (unlike the C64).
|
||
|
||
The DX-64 has the same characteristics as the SX64 except its two 5.25" floppy disk drives instead of one. A very small quantity was produced. It was probably never sold but only used by Commodore insiders.
|
||
|
||
The SX64 and DX64 computers never had success, probably because of higher selling prices, but were known as the world's first color portables.
|
||
|
||
The SX64 was not the only machine that Commodore made in this chassis, there was also the SX500, which was an Amiga in the SX case (see 'More pictures').
