I have found a Kaypro 4/84 in a non working state and some days ago i have decided to open it and i have realized that some components of the power supply are exploded and the video pcb was cracked.

I have not repaired the power supply because some components like the two burned transistors (Motorola W30 and V30) are not on the market, if you have more information about these components please leave me a message.

I had to fix the video pcb and i have installed a 200w Slim ATX power supply inside the Kaypro. I have made also other improvements to the computer, replaced the battery, totally exhausted and installing the KayPlus rom that offers some enhancements to this computer.

Below you can find the image of the Floppy Disk CP/M 2.2F 62k patched + Tools KayPlus in IMD format (ImageDisk) for the Kaypro 4/84.

from Wikipedia:

Kaypro Corporation, commonly called Kaypro, was an American home/personal computer manufacturer of the 1980s. The company was founded by Non-Linear Systems to develop computers to compete with the then-popular Osborne 1 portable microcomputer. Kaypro produced a line of rugged, portable CP/M-based computers sold with an extensive software bundle which supplanted its competitors and quickly became one of the top selling personal computer lines of the early 1980s.

While exceptionally loyal to its original consumer base, Kaypro was slow to adapt to the changing computer market and the advent of IBM PC compatible technology. It faded from the mainstream before the end of the decade and was eventually forced into filing for bankruptcy in 1992.

Kaypro’s first computer, the Kaypro II had a 2.5 MHz Zilog Z80 microprocessor, 64 KB of RAM, dual, single-sided, 191 kB 5¼ inch floppy disk drives, and an 80 column green monochrome 9″ CRT.

Early in the Kaypro’s life, there was a legal dispute with the owner of the Bigboard computer who charged that the Kaypro II main circuit board was an unlicensed copy or clone.

The outer case was constructed of painted aluminum. The computer featured a large detachable keyboard that covered the screen and disk drives when stowed. The Kaypro ran off regular AC mains power and was not equipped with a battery.

The Kaypro IV and later the Kaypro 4 had two double-sided disks. The Kaypro 4 was released in 1984, usually referred to as Kaypro 4 ’84, as opposed to the Kaypro IV released one year earlier and referred to as Kaypro IV ’83.

The Kaypro 10 followed the Kaypro II, and featured a 10 megabyte hard drive and a single 5¼” floppy drive.

AspeQt is a cross-platform, free and open source Atari 8-bit serial peripheral emulator. The name is an acronym for Atari serial peripheral emulator for Qt, Qt being the cross-platform application development framework used by AspeQt.

AspeQt emulates various Atari 8-bit peripherals like disk drives and printers via an SIO-2-PC cable. If you are familiar with software like Sio2Pc, APE, Atari810, AtariSIO etc., you probably won’t have any problems getting used to AspeQt.

Even though AspeQt is not fully mature yet, it is easy to use and, despite its shortcomings, has many features that you may find useful, the highlights being:

• Cross-platform GUI with drag and drop support.
• 8 emulated disk drives with support for 512 bytes per sector disk images.
• High speed operation up to 6 times faster than the normal speed.
• Ability to use PC folders as emulated disks.
• Disk image explorer for viewing and modifying disk image contents.
• Ability to run Atari executables without messing with disk images and DOSes.
• Printer emulation.
• Cassette image playback.

CBM prg Studio Version 2.1.0 Beta released. There are a lot of new features in this version. I’d really appreciate it if you report any bugs you find or have any suggestions/comments.

CBM prg Studio allows you to type a BASIC or Machine Code program in using a nice Windows environment and convert it to a ‘.prg’ file which you can run on an emulator, or even a real C64 or VIC20 if you’re feeling brave and have the right kit.

CBM prg Studio is the result of merging C64PrgGen and VIC20PrgGen. Adding new features and fixing bugs in two apps which were 95% similar was a bit of a nightmare so merging them made sense.

It was also a good opportunity for a face lift and to add some new features, such as:

• Programs are project based, meaning all related source files, sprite files etc. are kept in one place and multiple source files can be linked more easily.
• Tabbed MDI.
• Syntax highlighting.

What CBM prg Studio isn’t is a front-end for tok64, cbmcnvrt, bastext or any other tokeniser / detokeniser / assembler. It’s all been written completely from scratch.

Bugs fixed in v2.1.0:

• Occasional crash on exit.
• User specified project build order not being used/saved.
• Video ram location wrong in screen editor for VIC20 and C64 projects.
• Help file steals the focus and won’t let you use prg studio until it’s closed.
• D64 image name padded with the wrong character.
• Auto formatting assembly programs.
• Some errors being reported on the wrong or negative line numbers.
• Regions and TODOs getting confused with macros/instructions.

Directly from the blog of Jordan Mechner:

My Dad (yep, the same guy who composed the music for the original Karateka and Prince of Persia) called from New York to tell me he was doing some spring cleaning and had shipped me a carton of old games and other stuff of mine he’d found in the back of a closet.

The carton arrived yesterday. My jaw dropped when I saw what was inside.

No, I don’t mean the stacks of Spanish Drosoft versions of POP and Karateka (though those are cool too, especially if you have an Amstrad computer with a cassette player). I mean those three little plastic 3.5″ disk boxes nestled among them… which appear to contain the ORIGINAL APPLE II SOURCE CODE OF PRINCE OF PERSIA that I’ve been searching for, off and on, for the past ten years, pestering everyone from Doug Carlston to Danny Gorlin and everyone who ever worked at Broderbund, and finally gave up hope of ever finding.

For the correct operation of this computer i have made some repairs. Replacing some capacitors (see photo) and the rearrangement of the pressure arm of the floppy drive.

The fault of the power supply are the voltages. Under load the voltages +12 and +5 is lowered significantly.
