• MINESWEEPER for your ZX81
  will also run under ZX81-emulator XTender. Minesweeper is written by ZX-TEAM-member Bodo in pure BASIC. I have converted the programm to be compiled with MCODER2, a very nice tool to bring speed into your ZX81. The version you can download here contains both the converted, uncompiled MINESWEEPER, and the compiled one - too fast to run under XTender. Enjoy it.
• MCODER2 The true compiler for SINCLAIR ZX81 BASIC! Not written by a ZX-TEAM-member, but perhaps you would like to try it for you own programs, after having been surprised by MINESWEEPER.
  MCODER2 really will bring speed into your ZX81 programs. There are some limits, like integer numbers only and no string handling. MCODER2 comes with all instructions.
• TOOLKIT a very usefull tool for BASIC-programmers, comes in a 16K and a 64K version together with a brief instruction. Will run under ZX81 emulator XTender as well.
• PLATEDI is a PCB-editor written completely in assembler-code by Markus Schinhaerl. It requires 32K-RAM in 16-32K and 48-64K and some small hardware changes to run the included HRG8 routines.
  

  If you have a dynamic-RAM you must cut the REFRESH connection between ZX81 and RAM and rewire as shown in the image. This circuit will change each refresh-cycle into a read-cycle. If you use static-RAM, you will only have to connect the /WR-Pin of your RAM-chip via a resistor of 10 KOhm with 5 Volts.

  PLATEDI will not run on XTENDER, but on ZX81-emulator from Paul Robson. Do'nt forget, these emulators do not support the PC-Printer! PLATEDI uses its own printer-routines for ZX-TEAM-PIO-printerport and must be patched for your type of printer.
  (Sorry, at the moment, this service is available for ZX-TEAM-members only!)
• WURM is a nice game, too fast on XTENDER. It was written in 1984 by Michael Engelhard and compiled with basic-compiler MCODER 1 by me.
• MAQ calculates the number of magical squares of fourth order. It is written by Martin Weese in 1997 and compiled with MCODER 2 by me.
• See 5 sexy models in full action. (Yvonne, Eva, Emma, Twiggy and Cleopatra)
  This is "real adult only" software!
  It is written by Willi, one of the most serious ZX-TEAM-members. After 25 years of marriage, he risked his married life to support the ZX81 community with this absolutly indispensable programm!
  It will run under Xtender and on ZX81 with 16K memory.
