Some VIC-20 Games cartridges

Cartridges list:

  • VIC-1111 – 16k Ram Expander. (Manual)
  • VIC-1211A – Super Expander with 3k Ram Expansion. (Manual)
  • VIC-1213 – Machine Language Monitor. (Manual)

click here for the vic-20 cartridges category.

from Wikipedia:

As for commercial software offerings, an estimated 300 titles were available on cartridge, and another 500+ titles were available on tape. By comparison, the Atari 2600—the most popular of the video game consoles at the time—had a library of about 900 titles near the end of its production life (many were variations of another title).

Most cartridge games were ready to play as soon as VIC-20 was turned on, as opposed to games on tape which required a time-consuming loading process. Titles on cartridge included Gorf, Cosmic Cruncher, Sargon II Chess, and many others.

VirtualC64 v1.0 Beta 8 for Mac OSx

August 25th, 2009 No comments

VirtualC64 emulates a Commodore 64 personal computer on your Macintosh. I wrote the software with two major goals in mind. First, I wanted to create an emulator that can be used as a demonstrator program in a first year or second year course on computer engineering.

To achieve this goal, I have integrated various debugging capabilities that let you peek inside the CPU, RAM, ROM, or one of the custom chips. Second, I tried to make the emulator as user friendly as it can get.

In short: VirtualC64 tries to combine the ongoing fascination of the ancient Commodore computers with the great user experience of today’s Macs.

Changelog:

Fixed in beta 8

  • Joystick handler has been rewritten from scratch. It’s now message based and supports hot plugging.
  • Fixed a race condition that could cause the emulator to crash during shutdown.
  • Fixed some minor GUI issues.

ROM-el testing complete

August 23rd, 2009 No comments

ROM-elfrom Homepage:

Aries was backordered on the required 24 and 28 pin headers needed to finish testing, and the order just came in this past week.  Thus, I finally had a chance to solder and test the units.  Testing went well, and I can program the units with my Willem programmer.

Originally designed to hold a 29EE512 64kB EEPROM, I found a good price on Atmel AT49F001 128kB 5V Flash, so I made the necessary adjustments and tested with the new memory.  Testing went well, so I am releasing the design to production.

I have noticed one issue that I need to address.  Some CBM units have an RFI shield that doubles as a heat shield.  To perform the latter function, metal “fingers are stamped out of the shield that press on the top of the ICs.  I need to ensure the metal shield/heat sink does not contact any of the pins on this unit.

ACID 64 Player Pro v3.0.2 (Windows)

August 23rd, 2009 No comments

acid64playerlogoACID 64 Player Pro is the sequal of Acid 64 Player and is a cycle based Commodore 64 music player designed for playing SID tunes on sound cards/devices that have a real SID chip (6581/6582/8580) on board like the HardSID cards and HardSID 4U USB device.

ACID 64 emulates the MOS 6510 micro processor, the 6526 CIA chip and partially the 6569 VIC chip to run the code of a SID tune and it controls the SID chip on the device for playing the Commodore 64 music.

What’s new in version v3.0.2:

Fixes

  • No error anymore when last directory was a root folder.
  • Corrected memory bank setting for PSID tunes.
  • Resizing window was corrupting active row of search grids.
  • Minimal width is now set correctly.

Improvements

  • Last played file is remembered now when ACID 64 is started.
  • When Folders tab is clicked, the current selected file will always be visible.
  • Special characters Ø and ø can now be searched by o or oe (re-indexing required)
  • Pressing escape in search boxes will now select the text instead of clearing the input.
  • Selecting a search filter will change the color of the filter box.
  • Copy filename strips HVSCRoot automatically.
  • Seeking (dragging thumb) can now be cancelled by pressing escape key or by pressing right mouse button.
  • Scrolling search results will now update rows immediately without releasing the thumb.
  • Clicking on a folder name in Folders tab will expand the folder.
  • Changed “Browse” tab name to “Folders”

ZX Spectrum +3 (Issue 1) Sound Fix *updated*

August 22nd, 2009 2 comments

Sound fix diagram here. (pdf)

from Cristian Secară Homepage:

The first release (the +3) has a fatal hardware mistake: the 128K sound output is completely distorted.

  • Tech explanation: the analog output of the AY-3-8912 sound chip was intended to be amplified by a one stage common-emitter transistor. In practice, they have forgot to put a resistor to the transistor’s emitter. The result: the transistor works in switch-mode – the sound is converted from analog multi-level amplitude to digitized two-level amplitude, same as the old 48K sound system.

Sinclair (Amstrad) ZX Spectrum +2 (in the grey case) – Issue 3

August 22nd, 2009 No comments
Spectrum +2 (in the grey case)

Autopsy:

The original Plus2 (in the grey case) was released in 1987 to get away from the old Spectrums now that Amstrad had taken over. It was very different from previous Spectrums and had a proper typewriter keyboard, built-in casette recorder and 2 joystick ports.

For some unknown reason Amstrad later released a +2A in a black case which is actually a Plus3 with a casette recorder instead of a disk drive.

from Wikipedia:

The ZX Spectrum +2 was Amstrad’s first Spectrum, coming shortly after their purchase of the Spectrum range and “Sinclair” brand in 1986. The machine featured an all-new grey case featuring a spring-loaded keyboard, dual joystick ports, and a built-in cassette recorder dubbed the “Datacorder” (like the Amstrad CPC 464), but was in most respects identical to the ZX Spectrum 128. The main menu screen lacked the Spectrum 128′s “Tape Test” option, and the ROM was altered to account for a new 1986 Amstrad copyright message.

These changes resulted in minor incompatibility problems with software that accessed ROM routines at certain addresses. Production costs had been reduced and the retail price dropped to £139–£149.

The new keyboard did not include the BASIC keyword markings that were found on earlier Spectrums, except for the keywords LOAD, CODE and RUN which were useful for loading software. This was not a major issue however, as the +2 boasted a menu system, almost identical to the ZX Spectrum 128, where one could switch between 48k BASIC programming with the keywords, and 128k BASIC programming in which all words (keywords and otherwise) must be typed out in full (although the keywords are still stored internally as one character each).

Despite these changes, the layout remained identical to that of the 128.

Divide 57c in KIT *updated*

Divide 57c

Autopsy:

On the last Photo you see two Divide Interfaces. On the left, the PCB Green color, is the Original from DivIde Homepage , On the right, the PCB Red color, is a “clone” from Ebay.

Both working good, but the Divide “clone” has stopped to work after two weeks, chip ram 62256 is broken. Some components of Divide “clone” are differents from the Original Divide interface. like: some values of resistors.

Here it’s the correct picture of solder side on DivIDE 57c. (thanks to Valesoft)

from Divide homepage:

divIDE is an ATA (IDE) interface which takes your ZX Spectrum computing to a whole new level. As the time takes its toll on ageing media such as audio tapes or diskettes, many ZX Spectrum enthusiasts simply stick to emulation for better reliability and comfort.

With divIDE you can put your software collection to a hard disk, CD-ROM or even CompactFlash card and experience your favourite games, demos and utilities the way the were meant to be run – and even better. Using existing firmwares, many users find their Speccy box again a live platform – time for you to make the switch?

Features:

  • divIDE uses full 16 bits of ATA bus.
  • divIDE works on all ZX Spectrum flavours (16, 48, 48+, 128, +2, +2A, +3 and clones)
  • Thanks to divIDE’s onboard logic, theoretical transfer speed is 218 KB/sec (determined by the latency of INI/OUTI instructions).
  • divIDE has 8 KB of shadow flash ROM that hosts operating system core, leaving your original ZX Spectrum ROM intact. Additional 32 KB of RAM accessible as 8 KB memory banks are present.
  • divIDE’s auto-mapping feature transparently maps shadow ROM at important entry points, enabling standard tape emulation, BASIC extensions, NMI menu and DISCiPLE/+D or BetaDisk emulation.
  • divIDE’s MAPRAM feature helps developers and users to test new software without the need of reflashing their working system in shadow ROM. It can also emulate another 8 KB of ROM if necessary.
  • divIDE works with all ATA-compatible devices (there are no known compatibility issues).
  • Available software supports widely used emulator formats (TAP, SNA, Z80, SCR). Just download your all-time favourite games from the web and play!
