Programmable Turtle book and software for the Apple II lives on


Update 01/01/2021: Tesseract OCR applied to scan (300dpi Grayscale, lossless compression)
Update 03/10/2016: By combing the power of Alex Lukacz, we bring you the complete package of software and booklet.

On the 23rd of May 2016 I spoke with Greg Preston, president of the now folded NSW Computer Education Group.  Greg remembered Turtle well and brought my attention to the lower right corner “CEU 013”, and suggested that was book 13 of about 150.  My edition is a 1985 re-print and is a joy to read, as one can pickup the names of Australians working at CEU and their efforts.

An introduction is on PDF pg.12 as follows:

System requirements
“Turtle requires a 48k APPLE II computer with a disk drive”.




January has proven to be a great month for my Apple collection.  This post is to thank those who have generously given me their vintage gear or sold it at a bargain price.  I clean everything in my collection thoroughly with various styles of micro-fibre cloths, gumption, eucalyptus oil for the stickers and windex.  Keep in mind that computers of this age do collect a fair amount of dust so they have to be cleaned anyway.

The list for January, so far:

Macintosh SE Twin 800K floppy
PowerBook G4 17”
Commodore Amiga 1000
Macintosh Classic
Macintosh Classic II
PowerBook G4 15”
Apple Extended Keyboard II
Apple Mac Plus Mouse
Apple ADB mouse Wedge style
Apple iBook 2006 Core 2 Duo (with 4GB of RAM)
Performa 580

My impressions so far are:

  • SE 800K – The SE 800K has programmers switches and original everything.  It turned on first go with a very loud, clear chime into SSW 6.0.2 – 20meg hard drive installed too making it quite heavy.  Screen brightness is high and geometery correct.  Boots from floppy, reads quickly and ejects fine.
  • The Commodore Amiga 1000 is something I know nothing about and it didn’t come with peripherals
  • The Performa 580 is interesting to me as I have the Performa 580CD and assumed they all came with a CD drive.  Apparently not – this one just has a smooth line through where the CD drive is.  So a pretty useless machine for the time – a huge colour classic!
  • The PowerBook G4s run beautifully, and the iBook Core 2 Duo was restored to 10.4 and boots faster than my fully tricked out 2011 MBP!  The 17″ Matte screen is impressive and I wish we had a matte screen these days, battery lasts 3 hours and palm rests silky smooth.  The 15″ lasts about 50 minutes on battery, 1.25GB of RAM, OS X 10.5.8

Amstrad 640PPC

Over the past few days I’ve been playing with a new Amstrad PCC640. I recived it in as new condition with absolutely no sign of use – even the floppies were sealed. The bag however was filthy, blanketed in very fine dust that must have built up over the years. The unit itself though is like a time machine, after a once over with a micro fibre cloth it shines!

I formatted a real DS DD floppy to 720kb in windows and simply copied Commander Keen 4 CGA edition onto the floppy. Boot the Amstrad with the offical DOS 3.3 disk in A, this game in B. Run the executable and within seconds I had Commander Keen 4 with all it’s PC speaker glory.

The screen is nice with a desk lamp for text, but as I discovered today – motion isn’t good. Quite blurry with horizontal scrolls making Keen the wrong game for this display type.
