Czerweny Electronica CZ 1500plus

Czerweny Electronica CZ 1500plus, Argentina

The relabled clone CZ 1500 was quickly replaced by a successor in an own-style case assembled in Argentina, same as the CZ 1000plus got.

The CZ 1500plus had two standard joystick ports, a reset button and a video output in addition to the TV VHF output, similar to the CZ 1000plus.

Summary

Note: Acc. to www.old-computers.com there were 2 revisions, one with a grey key mat was built using lots of TTL chips (like the ZX80), and the later version with black chips used an ULA chip and consisted only of 4 ICs, like the ZX81/TS1000. This is odd, since the CZ 1500plus is already a successor of the CZ 1500. Though the CZ 1500plus a clone of the Timex Sinclair 1500, www.old-computers.com says that it only had 2 kB of RAM (like the TS1000 had). Long live C&P.
