Re: Small memory dump program

Re: Cross Chase on Lambda 8300

Both DStar and CrossChase work great on Lambda1. CrossChase however i very difficult with the rubber keys compared to the emulator. It seems as there is a delay from press to reaction.

Can your patches be applied to z88dk, so versions of DSTAR and CROSS-CHASE can be made for Lambda-version1?
Thank you olufson, for Lambda1 versions of DStar and CrossChase. I’ll try them on real hardware tomorrow.

Re: "wall" game for the Lamba 8300 / Power 3000

Hi again olufson :) Now I've uploaded the TZXduino firmware to my Arduino with SD/Ethernet-shield, and loaded WALL into my Lambda with a 16K RAMpack.

Re: Help in resurrecting my ZX81

I have measured wrong on the circuit, and updated the drawing.

Edit: This drawing is also wrong. I'll continue to measure.

Re: Lambda colour kit

Hi :) I try to understand the schematic of the Lambda Color Module. I've tried to match ICs on the picture and the schematic. There is one IC and drawings on the schematic I don't understand. Can anyone enlighten me? https://trello-attachments.s3.amazonaws.com/598af660300e0d55b35f5755/5a36e7929ce3cf...

Re: ZXblast - ZX81 memory extension plus USB

Has anyone tried to have ZXblast and ZXpand connected at the same time. Can they coexist?
