I am using EightyOne V1.12 emulator on my PC for playing ZX81 .P files and thought I would try some programming. I hit a snag immediately with trying to enter the commands as I could not work out the PC keys to use for switching to the various ZX81 keyboard.
I would appreciate it if some kind person could explain the PC keys I need to use to achieve whats needed
Thanks
Mike

Re: ZX81 Programming Problems
Can you give us a bit more details as to the program you are trying to enter and the problems you are experiencing when using the PC keyboard.

It takes a while to get used to the keywords entry system, but reading the zx81 manual will help

Re: ZX81 Programming Problems
Using the PC keyboard I can't find the key combination to get the white commands ABOVE each ZX81 key. I can achieve printing all the other values on each of the keys just not the ABOVE value.
I will have another look at the manual

Hi,
If you reset the ZX81, then the first key you press will give you the command in white. For example 'P' will give you 'Print'
This will get you started:

Re: ZX81 Programming Problems
You only get the command words when the ZX81 is expecting a command, hence the cursor is a ‘K’ (meaning command).
When the cursor is ‘L’ it is in letter mode. After pressing and holding SHIFT and then pressing return (FUNCTION/NEW LINE) the cursor will change to ‘F’ so you can enter a function.

Standby alert
“There are four lights!”
Step up to red alert. Sir, are you absolutely sure? It does mean changing the bulb
Looking forward to summer later in the year.
