This two-part loader is not quite as easy to use with an emulator, but it can be done * With a real ZX81, just load Block1.p and when ready, load Block2.p. Putting them on tape one after another is the easy way * With the emulator, the tricks are to disable fast loaders, and get both programs queued...

Some clarifications: - what is the reason for the line "E_LINE defw $4401 ; ld bc, $1c44"? E_LINE defw $4401 is creating two bytes ($44 and $01) at that point in the code. And giving it the lable "E_LINE". The assembly is building up the beginning portion of the ZX81 program. ld bc, $1c44 is commen...

Just posted ZxList 6.4 to the first post of this topic. It may be downloaded from there. No dependents, should run on any 32 or 64 bit Windows. 6.4 changes: * added disassembly of REM machine/code statements * fixed overwriting of ASM/BAS files * Byte dumps are now pre-pended correctly * Now validat...

Have you ever wanted an easy way to examine machine code in BASIC files? Zxlister 6.4 can now automatically disassemble machine code found in REM statements. It creates a BASIC/Assembler file from a P or 81 file. It can also save the machine code in BIN files. Zxlister runs on Windows (95/98 or XP/7...

The loader is ingenious. I see no way to generate it on the ZX81, at least not from the Basic environment. But if you create it using special tools, it will load, then auto-run this statement which will load the next block. 1 RAND USR 16393 The System Variable NXTLIN contains the address of the BASI...

I noticed the same thing when loading P files using the EightyOne's "Auto Load on Insert" feature. After turning that off, a manual LOAD "" does not cause a reset.

Works well on Chrome 37

I noticed:
* it loads with a black screen. The Reset button starts the ZX81
* the keyboard backspace key is not mapped to the Rubout key
* the edit line moves to the top of the screen at times, but seems to recover by itself

Progress on IE8 -- it now shows a keyboard and buttons for start, stop, reset, etc. Message: Object doesn't support this property or method Line: 12 Char: 2 Code: 0 URI: http://rullf2.xs4all.nl/jszeddy/canvas2image.js Message: Object doesn't support this property or method Line: 145 Char: 2 Code: 0 ...

Perhaps so. Prism Microproducts was the sole distributor of the ZX81 in Britain to small retail organisations with fewer than 20 outlets. They also published Sinclair User magazine. http://wikipcpedia.com/wiki/the-second-wave-as-pcs-abound/through-a-prism-%E2%80%93-sinclair-distribution/ http://www....

With IE 8 I know see a ZX keyboard!
