ST-Paint is a Drawing program that lets you make Atari St picture on Windows based PC.

ST-Paint is still in a beta phase and it’s made by Peter Jørgensen same author of the program Ym2149 Tracker.

Note from the author:

  • Windows mode (not complete)
  • Clipboard : Remember the last 15 clip.
  • Color Replacer : Use to replace a color somewhere in the graphic.
  • Poly Line: Load/save Neochrome picture / Load Degas Under/Overscan Picture*
  • Some other functions have been change, like the undo buffer in the polygon function, (now while drawing a polyg, and undo you will remove the last point, when finish the polyg and undo, you will remove the hole polygon.

Vtech Laser 128 Personal Computer (Apple II Clone)

December 28th, 2012 No comments
Vtech Laser 128 Personal Computer

Autopsy:

from Wikipedia homepage:

The Laser 128 was a clone of the Apple II series of personal computers, first released by VTech in 1984. Unlike the Apple II clones from Franklin, VTech reverse-engineered the Apple ROMs using a clean room design rather than copying them. Apple Computer challenged VTech in court, but unlike its efforts directed at Franklin, Apple was unable to force the Laser 128 off the market.

As its name suggests, the Laser 128 had 128 KB of RAM. Like the Apple IIc, it was a one-piece semi-portable design with a carrying handle and a single built-in 5¼-inch floppy disk drive. Unlike the Apple IIc, it had a numeric keypad and a single Apple IIe-compatible expansion slot, which gave it better expansion capabilities than a IIc. VTech offered a metal 2-slot card cage that sat alongside the Laser 128 and attached to the computer’s single slot, allowing for even greater expansion flexibility. The Laser 128 retailed for about $700, substantially less than the price of an Apple IIc.

Apple countered the Laser 128 with its upgraded Apple IIc Plus. VTech responded with the Laser 128EX and the Laser EX2. The Laser 128 was aggressively marketed, both by mail order firms and in retail and catalog stores such as Sears. Even though its ROM was not derived from Apple’s ROM, the Laser 128 series had a high degree of compatibility with its competition from Apple.

VTech owed much of this compatibility to the fact that they were able to license Applesoft BASIC (which constitutes the largest and most complex part of an Apple II’s ROM contents) from Microsoft just as Apple did, heavily reducing the amount of code that had to be reimplemented. Microsoft had made most of its money by keeping the rights to the software that it sold to others. Likewise, Apple had failed to secure an exclusive distribution license for the Applesoft dialect of BASIC, and VTech was free to buy it. Much Apple software depended on various assembly routines that are a part of BASIC in ROM, and it’s quite likely that the Laser would not have been as successful had it not had compatible ROM entry points.

Tatung Einstein TC01

Autopsy:

from Wikipedia homepage:

The Einstein was released in the United Kingdom in the summer of 1984, and 5,000 were exported back to Taipei later that year. A Tatung monitor (monochrome or colour) and dot matrix printer were also available as options, plus external disc drives and an 80 column display card. It was also capable of emulating the Spectrum 48k with the “Speculator” addon.

More expensive than most of its rivals, and lacking an obvious niche market other than technically-advanced home programmers, the Einstein was commercially unsuccessful. A later, revised version, called the Tatung Einstein 256 suffered a similar fate.

The machine was physically large, with an option for one or two built-in three-inch floppy disk drives manufactured by Hitachi. At the time, most home computers used ordinary tape recorders for storage. Another unusual feature of the Einstein was that on start-up the computer entered a simple machine code monitor, called MOS (Machine Operating System). A variety of software could then be loaded from disk, including a CP/M-compatible operating system called Xtal DOS (pronounced ‘Crystal DOS’, created by Crystal Computers in Torquay), and a BASIC interpreter (Xtal BASIC). Thanks to the reliability of the machine, and ample memory, the machine proved useful by many software houses to use for programming, and then porting the code to the machines they were made for, Spectrum 48k, Amstrad CPC, Commodore C64, this later stopped when the PC and Atari ST would emerge as the development systems of choice.

TRS-80 Model 1 Cleaning, Fixing, Painting… and other things

December 20th, 2012 No comments

I have gathered all photos of some phases of the work that i have done on the TRS-80 Model 1.

Below the descriptions:

  • Cleaning of Nicotine.
  • Replaced a bad capacitor.
  • Testing.
  • Floppy Drive before restoration.
  • Replaced Australian Power Connector of the Floppy Drive.
  • Restoration phases of the Floppy Drive.
  • *Making the floppy disk for TRS-80 Model 1.
  • Audio patch cable to hear the sound of the games.

*Is not been easy to make the Floppy for the TRS-80 Model 1 SSSD 35 TRK in FM format. Fortunately i have a old motherboard Pentium 133 with the right IO chip that supports writing format: MFM / FM SSSD.

Radio Shack TRS-80 Model 1 / Expansion / Floppy / Video Display

Radio Shack TRS-80 Model 1 / Expansion / Floppy / Display

Autopsy:

from Wikipedia:

TRS-80 was Tandy Corporation’s desktop microcomputer model line, sold through Tandy’s Radio Shack stores in the late 1970s and early 1980s, and one of the earliest mass-produced personal computers. The first units, ordered unseen, were delivered in November 1977, and rolled out to the stores the third week of December.

The line won popularity with hobbyists, home users, and small-businesses. Tandy Corporation’s leading position in what Byte Magazine called the “1977 Trinity” (Apple, Commodore and Tandy) had much to do with Tandy’s retailing the computer through more than 3,000 of its Radio Shack storefronts. Notable features of the original TRS-80 included its full-stroke QWERTY keyboard, small size, its floating point BASIC programming language, an included monitor, and a starting price of $600.

The pre-release price was $500 and a $50 deposit was required, with a money back guarantee at time of delivery. One major drawback of the original system was the massive RF interference it caused in surrounding electronics. Stricter FCC regulations on interference led to the Model I’s replacement by the Model III.

Radio Shack announced the TRS-80 (Tandy Radio Shack) at a New York City press conference on August 3, 1977. It cost $399, or $599 with a 12″ monitor and a Radio Shack tape recorder as datacassette storage. Before this, the most expensive product Radio Shack sold was a $500 stereo.

The company hoped that the new computer would help Radio Shack move into higher-priced products, and improve its “schlocky” image among customers. Small businesses were the primary target market, followed by education, then consumers and hobbyists. Despite its hobbyist customer base, Radio Shack saw hobbyists as “not the mainstream of the business”. Although the press conference did not receive much media attention due to a terrorist bombing elsewhere in the city that day, “six sacks of mail” arrived at company headquarters asking about the computer, and over 15,000 people called Tandy to purchase a TRS-80, paralyzing its switchboard.

Unlike competitor Commodore—which had announced its PET several months earlier but had not yet shipped any—Radio Shack began shipping computers by September. Still forecasting 3,000 sales a year, the company sold over 10,000 TRS-80s Model Is in its first one and a half months of sales, and over 200,000 during the product’s lifetime.
