Applied Technology MicroBee (Series 2 Educator) 50% Boxed

Applied Technology MicroBee (Series 2 Educator)

Autopsy:

I had to build the power cable (8.5 – 10 volts), video Composite output and In/Out tape, because was not given with the computer as standard.

from Wikipedia:

MicroBee (Micro Bee) was a series of home computers by Applied Technology, later known as MicroBee Systems.

The original MicroBee computer was designed in Australia by a team including Owen Hill and Matthew Starr. It was based on features available on the DG-Z80 and DG-640 S-100 cards developed by David Griffiths, TCT-PCG S-100 card developed by TCT Micro Design and MW6545 S-100 card developed by Dr John Wilmshurst. It was originally packaged as a two board unit, with the lower “main board” containing the keyboard, Zilog Z80 microprocessor, Synertek 6545 CRT controller, 2 kB of “screen” RAM, 2 kB of character ROM (128 characters) and 2 kB of Programmable Character Graphics (PCG) RAM (128 characters). Each byte in the screen RAM addressed a character in either the character ROM or PCG RAM. A second board, termed the “core board”, contained the memory, and on later models also included a floppy disk controller.

The computer was conceived as a kit, with assembly instructions included in Your Computer magazine, in June 1982. After a successful bid for the New South Wales Department of Education computer tender, the computer was repackaged in a two-tone beige and black case, and sold pre-built. The 16 kB ROM held the MicroWorld BASIC interpreter written by Matthew Starr and DGOS (David Griffiths Operating System) compatible System Monitor. In addition to the 16 kB ROM, there is additional ROM socket for optional programs such as WORDBEE (Word processor) or EDASM (a Z80 Editor/Assembler that was written by Ron Harris).

Original MicroBees ran at a clock speed of 2 MHz, with a video dot clock of 12 MHz, which was sufficient to display 64 × 16 characters (512 × 256 pixels) on a modified television or composite monitor. The original machines were supplied with 16 or 32 kB of static RAM, and stored programs on cassette, using 1200 Baud encoding.

Apple IIe (Apple //e)

Apple IIe

Autopsy:

from Wikipedia:

The Apple IIe (styled as Apple //e) is the third model in the Apple II series of personal computers produced by Apple Computer. The e in the name stands for enhanced, referring to the fact that several popular features were now built-in that were only available as upgrades and add-ons in earlier models. It also improved upon expandability and added a few new features, which, all combined, made it very attractive to first-time computer shoppers as a general-purpose machine. The Apple IIe has the distinction of being the longest-lived computer in Apple’s history, having been manufactured and sold for nearly 11 years with relatively few changes.

Apple had planned to retire the Apple II series after the introduction of the Apple III in 1980; after that machine turned out to be a disastrous failure, management decided the further continuation of the Apple II was in the company’s best interest. So after three and a half years at a stand-still, came the introduction of a new Apple II model — the Apple IIe (codenamed “Diana” and “Super II”). The Apple IIe was released in January 1983, the successor to the Apple II Plus. Some of the hardware and software features of the Apple III were borrowed in the design of the Apple IIe. The culmination of these changes led to increased sales and greater market share of both home and small business use.

One of the most notable improvements of the Apple IIe is the addition of a full ASCII character set and keyboard. The most important addition is the ability to input and display lower-case letters. Other keyboard improvements include four-way cursor control and standard editing keys (Delete and Tab), two special Apple modifier keys (Open and Solid Apple), and a safe off-to-side relocation of the “Reset” key. The auto-repeat function (any key held down to repeat same character continuously) is now automatic, no longer requiring the “REPT” key (now gone) found on the previous model’s keyboard.

Regenerator disassembler v1.3 by n0stalgia

May 16th, 2013 No comments

Regenerator is an interactive disassembler for C64 binaries. Regenerator will load any standard C64 .PRG file (or VICE snapshot) and disassemble it for your convenience.

There are a few options you can choose to change the output and a few tools to make the output look better and more useful to programmers. Regenerator runs under M$ windows and need .net 3.5 (or 4.0) runtime.

New in version 1.3:

  • Added REMOVE command to remove part of the data from dissasembly.
  • Added EDIT BLOCKS window to Edit all the DATA, TEXT and REMOVED blocks manually.
  • Added COPY to Clipboard functionality (insert key) with FULL or CODE only modes.
  • Added possibility to add user-defined COMMENTS to the code. This can be done as a FULL line comment or as a SIDE comment!
  • Added USER LABELS – you can now add a label to any address and it will be used in the disasembly. If there should be an automatic label generated for it then it will be overriden. Also added USER LABELS editor which is part of the old Label Prefixes window. You can add/edit and remove user labels within this screen and have a general overview of the user labels.
  • Added high and low partial references to immediate opcodes. This means that code like LDX #$A0 STX smwhr LDX #$BB STX smwhr+1 will be disasembled as LDX #<pBBA0 STX smwhr LDX #>address STX smwhr+1. This includes loads and stores in different order and with different registers. There is also a context menu command that lets you disable this on a currently selected address (if auto creation fails). NOTE: excluded address in STA opcodes will not be generated like this!
  • Fixed the Add BLANK LINE and Remove BLANK LINE so it actually works as it should.

SD2Snes Tiny status update

Tiny status update of the SD2Snes Cartridge from Ikari

Directly from the SD2Snes Homepage:

So I’ve been getting a lot of questions pertaining to current progress, understandably. ;)

SuperFX is still crawling along, I’ve gotten a basic CPU core control unit and partial instruction decoder to work which can run test code in simulation fine, albeit limited. But it doesn’t deal with the different memory delays, stalling and parallelism yet; also the SNES interface, plot logic and other supplementary stuff are still missing.

The SuperFX uses pipelining which is a thing I haven’t fully understood yet, so that’s going to take some brain work and likely multiple complete rewrites of the CPU core. I’d rather not give an estimated time of completion for that at the moment… ;) Implementing pipelining properly is important because game code is laid out to take advantage of it and will not run correctly otherwise.

Besides the SuperFX, kogami has discovered a BS memory mapping bug, a regression that snuck into firmware 0.1.5 where I rewrote the BS memory mapping based on my own RE efforts. Also some graphical corruption has been found when using the “Run previous game” feature (Start button). I expect to make a bug fix / minor release addressing these issues (possibly others) in a couple of weeks.
