This is a Apple II clone made by Computertechnik (SK-747 IBS Space 84) around late 70′s. This Apple computer resembles in all respects the original one.

from Wikipedia:

The Apple II is an 8-bit home computer, one of the first highly successful mass-produced microcomputer products, designed primarily by Steve Wozniak, manufactured by Apple Computer (now Apple Inc.) and introduced in 1977. It is the first model in a series of computers which were produced until Apple IIe production ceased in November 1993.

The first Apple II computers went on sale on June 5, 1977 with a MOS Technology 6502 microprocessor running at 1 MHz, 4 kB of RAM, an audio cassette interface for loading programs and storing data, and the Integer BASIC programming language built into the ROMs. The video controller displayed 24 lines by 40 columns of monochrome, upper-case-only (the original character set matches ASCII characters 0×20 to 0x5F) text on the screen, with NTSC composite video output suitable for display on a TV monitor, or on a regular TV set by way of a separate RF modulator.

The original retail price of the computer was 1298 USD (with 4 kB of RAM) and 2638 USD (with the maximum 48 kB of RAM). To reflect the computer’s color graphics capability, the Apple logo on the casing was represented using rainbow stripes, which remained a part of Apple’s corporate logo until early 1998. The earliest Apple II’s were assembled in Silicon Valley, and later in Texas; printed circuit boards were manufactured in Ireland and Singapore.

I have recovered a Osborn 1 in pretty nice cosmetic conditions but broken ;-(

List of broken stuff:

• Startup Garbage screen.
• Long startup beep.
• Reset works 1 times out of 20.
• Modem port desoldered.
• Powersupply ripple.
• Some screws missing.

Solutions & Fixes:

• Powersupply Ripples: Replaced some capacitors.
• Modem Port de-soldered: Fixed the cold solder.
• Startup garbage screen/long beep/reset: I have replaced a broken 4116 RAM.
• Screws missing: Replaced with a new one.

I have to thank Terry ‘Tezza’ of Classic Computers Blog for the piggyback ram guide.

I used an oscilloscope to find the faulty ram cause all ram in my motherboard seemed to work well. In the photo #9 you can see the signal of the pin 2 (data in) of a faulty ram, while in the photo #8 the same signal of a working a ram.

from Wikipedia:

The Osborne 1 was the first commercially successful portable microcomputer, released on April 3, 1981 by Osborne Computer Corporation. It weighed 10.7 kg (23.5lb), cost USD$ 1795, and ran the then-popular CP/M 2.2 operating system. The computer shipped with a large bundle of software that was almost equivalent in value to the machine itself, a practice adopted by other CP/M computer vendors.

Its principal deficiencies were a tiny 5 inches (13 cm) display screen and use of single sided, single density floppy disk drives which could not contain sufficient data for practical business applications.

The Osborne’s design was based largely on the Xerox NoteTaker, a prototype developed at Xerox PARC in 1976 by Alan Kay. The Osborne 1 was developed by Adam Osborne and designed by Lee Felsenstein. It was first announced in April, 1981. Adam Osborne, an author of computer books, decided he wanted to break the price of computers.

The computer was designed to be portable, with a rugged ABS plastic case that closed up and a handle. The Osborne 1 was about the size and weight of a sewing machine and was advertised as the only computer that would fit underneath an airline seat. It is now classified as a “luggable” computer when compared to later laptop designs such as the Epson HX-20.

Hoxs64 written by David Horrocks is a Commodore 64 emulator for Microsoft Windows 2K/XP/Vista/Seven (DirectX 9+)

The emulator substantially reproduces this legacy machine in minute detail.

Changelog:

• Enabled editing of the CPU registers and the disassembly mnemonics. The mnemonic edit box accepts either 6502 assembly or space delimited numbers.
• Fixed pixel glitch while stepping in the debugger.
• Added up/left soft cursor keys.
• Tweak for demo ‘Bad Copy’ by Emulamer.

Sorry, this entry is only available in Italian.

Turbo Chameleon 64 is an extremely user-friendly cartridge that can be used without opening the computer. It is just plugged to the expansion port of the C64.

The Turbo Chameleon 64 cartridge can also be operated as a stand-alone unit (since it’s basically an FPGA computer like the C-One or the Minimig in a C64 cartridge case), replacing the computer, the floppy drive and the heavy power supply.

When used as a stand-alone unit, a USB power adapter or active USB hub can be used as a power source.

Changelog:

Differences from Beta-6f to Beta-6g:

• Implemented bit-fade in SID when no waveform is selected.
• Implemented bit-fade in SID when reading write-only registers.
• Added bits to detect in menu when disk-images need update after write actions by the emulated drives.
• Implemented “door” on emulated drive, when open drive will read dummy bytes.
• Fixed CPU instruction timing bugs discovered when comparing emulated 6510 against real 6510.
• CPU irq/nmi timing fixes.
• Implemented bit-fade on I/O port of emulated 6510.
• Fixed SID stereo mapping for D500 and D700.
• Four timers added at addresses D0AA to D0AD for menu (it can’t use CIA timers when freezing).

After ten years of use, i finally decided to replace my old Willem programmer with an updated version of this nice programmer. The Willem PRO 4 ISP.

Willem PRO 4 ISP is the most popular programmer on Europe. Programmer is built on two-sided laminate with metal-plated openings, solder mask complete with description of components.

Willem PRO 4 ISP could be connected into devices directly via ISP (In System Programming) connector.The main advantage of ISP is possibility to program devices directly in place without any need to dismount them. Because of that and high-tech software solutions our programmer is much more useful in various programming tasks. ISP could be powered directly by Willem Programmer or by device’s power supply.

Kick Assembler (written in Java language) is the combination of an assembler for doing 6510 machine code and a high level script language.

8/9-2011 : New beta release (v3.20 & v3.21):

• Made mnemonic extensions to force all addressing modes.
• Corrected bug in error message when forcing an illegal addressing mode.
• Made mnemonic extensions so you can force addressing modes. ‘.z’ and ‘.zp’ forces zeropage, ‘.a’ and ‘.abs’ forces absolute. Eg. lda.abs $0000
• Made .importonce directive to ensure libraries only gets included once.
• Corrected typo in error message. Thanks to Tlr for pointing this out.
