The source code and executable's for these 2 utilities are attached at the bottom of this page along with a few (no need for an audio cassette recorder to save your programs) SYMsave.exe will transfer blocks of memory from the SYM-1 to a hex file on the PC. SYMpgmr.exe will transfer intel style hex files generated by DASM to the SYM-1 and

Using DASM made writing code for the SYM-1 much easier but I still needed a way to get it from the PC to the SYM-1.

Tons of great resources including a link to a SYM-1 Simulator can be found here: ĭASM is a 6502 assembler program for the PC. Its advantages over the KIM-1 lie in its expandability to 4K user RAM on-board, the provision for up to 8K of ROM or EPROM on-board, a lot more I/O lines, an improved Monitor program, higher cassette tape I/O rates, and a number of other nice little features. While more advanced than the KIM-1, the SYM-1 was designed to use the same peripheral cards and data storage protocols for compatibility reasons. The SYM-1 is similar to the KIM-1, another single board computer (SBC) which was released by MOS two years earlier, in 1976. Best uses include learning to program, simple machine control, and sensor monitoring.

It is a simple computer systems made from basic hardware and software components. "an ideal introduction to the expanding world of microprocessor technology as well as a powerful development tool for design of microcomputer-based systems." The Synertek SYM Model 1 computer is "one of the most versatile and sophisticated single-board computers available", Recently, I dug it out and powered it up. That came in the (very worn) packaging see in the photo below. Years later, the keyboard stopped working (a common problem) so I sought out a replacement unit from ebay. I remember coming across this for sale at CVS (including the 16K RAM pack) for $29.99 although I can't remember exactly when. The system shown above has the optional 16K memory expansion unit attached to the back.
It was still very popular when they came out with the improved ZX-81 in 1981.īy mid 1982, Timex was selling the ZX-81, renaming it as the 'Timex Sinclair 1000'. The first Sinclair computer was the ZX-80, released in 1980 for $200.00. They are nearly identical, except for the name on the front, and minor motherboard layout differences. The Timex Sinclair 1000 is the North American version of the Sinclair ZX-81, from British based Sinclair Research Ltd. Famous for being very slow (serial), noisy, and prone to failure. It was rather slow, transferring data at only 300 baud.Ī floppy drive was eventually released - the famous 1541.
Originally, the only method of storing your own data was on the proprietary Commodore Datasette recorder. All this make it an excellent game machine, which is what it excelled at the most, with thousands of software titles release and numerous peripherals to extend its capabilities. The C64's microprocessors support two high-resolution graphic modes, smooth scrolling, "sprites", bit mapping, character collision resolution and character mapped graphics, not to mention three channels of complex sound. They are similar, but the C64 is more powerful with more features. The C64 looks nearly identical to the Commodore VIC-20, released in 1981. (thankfully I never gave up the monitor)ĭisplay 25x40 Text, 300x200 16 colors graphics. Later I longed for my old C64 again and ended up searching ebay to get another system. At one point I donated my entire box of C64 stuff to Goodwill.
