Description

Available to pre-order for your retrocomputing pleasure - ZXpand+

A quick word from SirMorris:

  Starting a new run of boards is expensive. There is a large initial outlay to get PCBs and components ready. I am using the pre-order mechanism to help with this up-front cost.


  I am initially offering 100 units for sale to be completed in batches of 25. I expect production of the first batch of boards to start in early October. 

Batch one ends 1st October 2018
Batch two ends 1st January 2019
Batch three ends 1st April 2019
Batch four ends 1st August 2019

When you order before the batch cut-off point expect delivery within 4 weeks.

Of course I will be happy to answer any questions you have, please message me.

Thanks!

------------------------------------------------------------------------------------

The ZXpand plus is the follow-on model of the ZXpand Classic. It boasts an improved hrdware and software specification.

* AY sound built-in

Featuring a Yamaha YM2149F PSG now all the games have no excuse not to offer sound effects :D There is stereo output from the on-board 3.5mm jack socket. Eight of the chip's IO connections are exposed on the interface's bottom edge for the more experimental among us. Easy 'turbo' upgrade via a plug-in adapter board.

* Joystick ability built in

Rather than crowd the board with a d-sub plug I have opted to expose the joystick input via the extension connector and a flying lead. This de-couples the interface from any movement of the joystick's plug, adding to the stability of the interface.

* Serial IO

5V TTL serial I/O is available on the extension connector. What to connect here? Well it's up to your imagination. Mouse? Arduino project? ESP8266? The possibilities are endless.

* SD card interface

Simply LOAD or SAVE the program you want, no POKEs, USR commands or drivers required. Fully integrated into Sinclair BASIC. Uses standard FAT formatted cards. Directories are supported so you can organise your files as you wish.

* 32K RAM

No need for a RAM pack. RAM is hires capable, allowing WRX, ARX and other hires schemes to work. Flexible memory mapping allows for RAM at 8-40k or 16-48k. 

* BASIC extension commands

SAVE and LOAD, CAT, ZXPAND and CONFIG are available from the keyboard. Due to space restrictions in the ROM these commands replace the printer commands. Printer commands can be made available if required with a simple command. 

* Misc

Reset button, easy firmware upgrades, actively supported


An english language manual is available here.

Support is always available either at the SinclairZXWorld forums for general advice, or via email from the developer.


Interfaces will be shipped first-class recorded in a sturdy box and anti-static wrap within 3 working days.
