SpartaDOS X (or SpartaDOS 4.0) is a disk operating system for the Atari 8-bit family of computers, that closely resembles MS-DOS. It was developed and sold by ICD, Inc. in 1987-93.

Ten years later SpartaDOS X considered abandonware has been picked up by its enthusiasts, and developed further. These unofficial revisions, incorporating many of the utilities written since 1992, cleaning many identified problems and including numerous improvements.

Highlights:

• Improved compatibility of 1 MB RAMBO and 576k Compy Shop RAM extensions with the internal BASIC on XL/XE.
• CAR.COM: added support for the Weronika cartridge: to run the dedicated programs, use CAR /F filename.ext;
• INIDOS.SYS should now work for SIDE2.
• Fixed a major bug in the S_VBXE driver, which caused occasional hang ups after the Reset key was pressed.
• CON.SYS: 80-column mode can now survive a warm reset.
• CHKFAT.COM: new command line tool to verify FAT file systems compatibility with our FATFS driver
• New program: MD5 hash tool
• SC now version 1.0.0

A new firmware and flashtool is availible for Sys-Check V2 series.

The new flashtool now supports both Sys-Check PCBs equipped with a SST39SF010A flash chip (V2.1 and V2.2). When you start the flashtool, it will ask you which version you have. To be absolutely sure, the flashtool shows a simplified graphic view of both versions. I think, everybody can handle it :)

Of course the flashtool (and all other documents) are written in german and english.

Also there´s a new firmware V1.4 out. This firmware can be used with ALL Sys-Check versions – also with the old V2.0 (without flash). Owners of the V2.0 must burn the 16 KB firmware image into a 27128 EPROM. All other please use the flashtool to update their Sys-Check.

V1.4 has this minor changes:

• Sys-Check can be used with the U1MB expansion.
• The new version first checks the whole memory (to be more exact… the first 48 KByte) and then displays the defective bits (if there are any…)
• When bad memory within the first 48 KB is found, the upper 16 KB will not be tested.
• If memory is fine, OS-ROM will be tested as before.
• If both tests are fine, then pressing START after this will set Sys-Check into endless loop test mode. Memory and OS-ROM are tested infinite – until any error occurs.
• During memory tests the background will be coloured red if defective bits were detected.

I have sacrificed a Floppy Disk Drive Commodore VIC 1541 to give a new look to a Floppy Disk Drive Commodore 2031 (IEEE-488).

It ‘s not been an easy job, but i’d say the result is very good.

I used a product to regenerate the rubber keypad of remote controls to repair the keyboard flat cable of a Home Computer MSX.

I have used this product many times for my work of Retro Computer restoration but never to regenerate the rubber keypad of remote controls :D
