Roger Wagner’s ‘Assembly Lines: The Complete Book’ re-released under Creative Commons

Announced by Chris Torrence via Usenet Comp.Sys.Apple2

Assembly Lines: The Complete Book is now available! The book contains all 33 of Roger Wagner’s articles from Softalk magazine, as well as appendices on the 6502 instruction set, zero-page memory usage, and a beginner’s guide to using the Merlin Assembler. The book is currently available for 40% off on Lulu.com, and will be available at Amazon in a few weeks. Note: Roger Wagner has released the book under a Creative Commons NonCommercial-ShareAlike license, and I’m currently working on the eBook version.

FYI, I uploaded disk images of the Assembly Lines programs to the Asimov website:

ftp://ftp.apple.asimov.net//pub/apple_II/images/programming/assembler/AssemblyLinesWagnerDOS1.DSK
ftp://ftp.apple.asimov.net//pub/apple_II/images/programming/assembler/AssemblyLinesWagnerDOS2.DSK

ftp://ftp.apple.asimov.net//pub/apple_II/images/programming/assembler/AssemblyLinesWagnerProDOS2.DSK

There are DOS and ProDOS versions. Disk1 contains the programs from chapters 1-17, while Disk2 contains the remaining chapters. Note that a few of the programs (in the DOS chapter) will only work in DOS, not ProDOS.

You can download a copy of the Merlin assembler for DOS at:

Ivan Drucker releases ‘Magic Goto’

Announced by Ivan Drucker via Facebook

Magic Goto is now available, so you can program in Applesoft without ever having to think about line numbers, yielding better organized and much more readable code.

It lets you GOTO, GOSUB, or ONERR GOTO a label in a REM statement. For example, GOSUB “showMainMenu” will find the line containing REM “showMainMenu”.

Magic GOTO is self-contained in your Applesoft program and does not require any additional files to be loaded.

For those already familiar with Magic Gosub, this supersedes it, with support for GOTO and ONERR GOTO; better performance; and the ability to specify your label search either forwards or backwards, starting from the top, bottom, or current line (this allows you to reuse labels if you are programming in Structured Applesoft).

Have fun: http://ivanx.com/magicgoto

Kevin Smallwood to release GBBSPro under the GPL

Kevin Smallwood announced in the Facebook Apple II Enthusiasts forum that he intends to release the GBBSPro bulletin board system (along with ACOS and other related products) under the GPL. Kevin is the current owner of the GBBSPro product.

To my fellow Apple // fans. Tony Diaz and I are going to GPL the GbbsPro source code. Stay tuned. -Kevin Smallwood

Tony Diaz has a huge collection of GBBSPro/ACOS material, so in tandem, they will be releasing a literal treasure trove of Apple II telecommunications history and source code. We could even see a resurgence of interest in good ol’ fashioned Apple II BBS’ing, as several people have expressed their desire to update the code to support telnet access.

CFFA 3000 run #4 delayed until November 2015

In an e-mail to interested buyers, Rich Dreher dropped the bombshell that the next run of CFFA 3000 boards will be delayed until November 2015! The community had been looking forward to early spring 2015 for availability.

Rich’s announcement is posted below:

Dear Apple II fans,

You are receiving this email because you have expressed an interest in the CFFA3000 card (an Apple II interface card). If you want to be removed from this list please let me know.

After 12 years of building cards the interest level in the CFFA remains high, with over 200 people expressing an interest in purchasing a card from Run 4. Unfortunately, for personal reasons, I need to postpone the next run of the CFFA3000 cards (Run 4) until November 2015.

I will notify you as soon as we are ready to take pre-orders, in late fall 2015. I am sorry for the delay.

Sincerely,

Rich Dreher

UltimateApple2 preparing to release several new products

Anthony Martino and Henry Courbis are about to offer for sale several new products. First up is the new ‘8 MEG RAM CARD v2.0′ for the Apple IIGS that is switch selectable between 4MB-8MB in 1MB increments, making it fully compatible with both the ROM 01 and ROM 3 Apple IIGS. We’re anticipating being able to review this card very soon, so stay tuned for updates. Pricing has not yet been disclosed but availability should be only a few weeks away.

Just built and testing the first few 8 Meg RAM Cards (see pic). What makes this card unique and the best solution out there for your IIgs memory needs? Well I’m glad you asked!

The Ultimate-ReActiveMicro 8 Meg RAM Card features Gold Fingers for superior oxidation prevention and long life.

Tantalum and Ceramic capacitors for longer life (4x minimum), extreme reliability, and they are very stable over time especially when compared to aluminum electrolytic capacitors.

A resettable Fuse for short-circuit protection and to help prevent Tantalum Capacitor thermal runaway.

ROM Expansion/Direct Access for future projects.

DRAM Address Termination.

Full Power Decoupling and Filtering for ALL chips.

Power LED to show the board is receiving power and the Fuse is functioning correctly.

And of course what project is complete without a blinky LED? We have TWO DRAM LEDs to show access and functionality! One LED for each bank of 4 Megs.

As you can see from the pic we also did away with the jumper and used a simple to understand DIP Switch along with adding the legend on the board so it can’t be lost.

Some may wonder why we used a CPLD yet kept the 74F245. Yes we could have added the logic to the CPLD however the 74F245 is meant to drive a higher TTL load (the data bus) than a CPLD. So although it would technically work it’s not good practice. This is also why we used DRAM Address Termination – to reduce ringing and related signal issues, and is just good design work.

Apple //e users and other 8bit fans won’t be left behind. Got RAM? Also coming are cloned versions of the Applied Engineering RAMWorks 2MB expansion and RAMFactor 4MB expansion cards. Expect a much improved No-Slot-Clock with user replaceable battery as well!

From James Littlejohn, offered exclusively through UltimateApple2 will be the new ‘LittlePower Flip’. The new LittlePower Flip is an improved design, essentially combining the previous LittlePower IIGS, IIe and II+ (three separate adapters!) into a single ‘flippable’ super adapter. The Flip will be perfect for quickly testing those dodgy power supplies, motherboards or even when used as a permanent part of your Apple II computer’s power solution.

Tecnobytes sells out limited batch of Apple IDE cards… more coming soon

Tecnobytes Classic Computers announced yesterday via the Facebook Apple II Enthusiasts forum a small run of 10 boards for their new Apple IDE card (a ‘replica’ of the original CFFA v2.0 from R&D Automation) would be for sale. Within a few hours, they were quickly snapped up for $125 each (including shipping). Tecnobytes promises more are coming — and as soon as they’re available, we’ll post it here.

GGLabs out with new 8MB RAM card for Apple IIGS

GGLabs has started selling an 8MB RAM card on eBay called the RAMGS-MAX. Similar to their 4MB RAMGS card offering, this card uses ZIP style DRAMs, making the board extremely compact. Also as before, it appears this card will be open-source. I think I’ll try to get one of these boards and check it out.
