ZX81XT extender board for developers

Post by PokeMon »

Here some information in the developers section, too. Because the board is designed for developers. ;)

The board is back.
Now available again for GBP 6.50 on sellmyretro.com.

Here the board as sold (with ZX81 edge connector with "key"):

Here used in a development, at this time only power supply needed for a video board. ;)

Development boards / projects could easily beeing changed by changing the slot card.
But better to have some more extender boards. :mrgreen:

I found this on Ebay a couple of years. This is their current listing: http://www.ebay.com/itm/Pack-of-5-Proto ... 25689d782d. The company that makes them also has it's own website - see this http://www.protostack.com/boards/protot ... dc-support. I was able to adapt this for my own use.

I have some similar extenders like PokeMon's that I got from one of my Ebay purchases years ago, only mine are much older and PokeMon's are in much better shape :D !!

Over the time this board ran out of stock and was unavailable about 4 weeks - but now available again.
The price did slightly increase from GBP 5.50 to GBP 5.90 due to new production price for a smaller series of boards.
This is including the ZX connector, shortened to length and soldered to the board already.
You will find it on sellmyretro.com again.
