Description
Thanks for looking at our listing for this Sinclair ZX 81, Issue 1 Board with a rare 8112 ULA
In great condition for its year.
Comes with a new membrane keyboard on the front and has been upgraded to work on new TV’s.
Selling it with a 16K RAM Pack.
In good working condition.
Work done:
- All electrolytic capacitors have been tested to make sure that the ZX-81 has a stable power supply.
- The insides of the RF modulator have been swapped out for another custom PCB that gives the ZX-81 excellent composite video output and produces the needed back porch to allow the ZX81 to give a crystal clear picture on modern TV’s – and it uses the same socket as the RF modulator used to so that we don’t have to modify the case at all.
- Replaced the Z80
- Replaced the regulator
Comes With:
- Original Sinclair Power Supply Unit which has been recapped
- Polys and cover (both showing signs of age, see pictures)
- ZX81 Basic manual
- Original Sinclair 16k RAM pack with polys and cover
Ideal For A Vintage Computer Collector Or Sinclair Enthusiast.
