Attached are a Sponzy version, and a ZX81 program to start it, so that TAPs such as FLIPPIT can be loaded via USB on the ZXmore.

Is the Sponzy-Rom in the ZIP a special version (patched?) or ZSOLT's original version?
Just to avoid possible confusion ...

Have a ZX81 at instance 1, and program the Sponzy in the Flash ROM at instance 2.

Great

PS: Instance 1 may also be a ZX81x2m.rom? Correct?

Yesterday I used my old "Merker Zeddy" to test my own patches of the ZX81X2 rom: http://forum.tlienhard.com/phpBB3/viewtopic.php?f=2&t=300&p=1488&hilit=merker#p1488 This Zeddy has a "language" card, which allows to map RAM to 0K-8K to test a new rom (a new "program language") in RAM, before an EPROM...

Speed on ZxMore (incl. Wilf's WHY-WAIT mod.): 263,5% @ 3,25 MHz , 529.3% @ 6,5 MHz

Andy: now its your turn using your 20 MHz Zeddy ....

Works also on ZX81:

Great

Now I need to add my own patches (LOAD/SAVE/LPRINT/POKE) to the asm file to run it on my (slightly modified ) Zeddies ..

Thanks for that big bang

Is there any way that the data could be sent to the pc instead of a printer (thaf the 81 thinks is a printer) so the picture can be saved on the pc that way? I've pre-ordered the ZXpand+ and I was wondering if the possibility existed alongside a serial link. Indeed there is a possibility: ZeddyNet ...

That are 4 analog switches (IC version of a relay). Maybe a CD4066?

I did this (56K Zeddy, ZEDIT version): load TURTLE.TXT to 32768 run "clisp-init" run "clisp" Result is IMG_1811_640x480.JPG :D Siggi BTW: for WIN systems the termination char 26 is better than char 0: some text editors handle a \0 terminated file as binary data, but accept char 26 as well-known EOF ...
