Sinclair ZX80 / ZX81 / Z88 Forums

I've read Andre***'s ZX91, and he uses 'Word Sinc II (P. Hargrave Nanaim)'. Is this available anywhere? I think I have found Word Sinc II here: http://www.theoldcomputer.com/roms/getfile.php?file=Li9TaW5jbGFpci9aWDgxL1ZhcmlvdXMvV1NJSS4zJTIwJTI4MTk4MyUyOSUyOFAuJTIwSGFyZ3JhdmUlMjkuemlw However it pri...

Using a transistor or an analog switch, one key can "press" multiple ZX81 key at once. Here is an example I use to have "Backspace" (BS) and "/" on a single key: http://forum.tlienhard.com/phpBB3/viewtopic.php?f=2&t=915&hilit=tasten#p8838 I looked at the Maplin instruktions yesterday evening and fo...

Hi :) Now the keys from China has arrived. They've been place loosely on top of a pcb. The keys are small 1.2 x 1.2 cm, and the transparent plastic can be opened up, og a small piece of paper can be place under the transparent plastic. E. g. look at the key with Q. This will be a small keyboard with...

Hi :) I've downloaded 'Hi-Res Word Processor (1983) (Nissim Elmalehes) from this page: http://nitroroms.com/list/Sinclair%20ZX%20Spectrum/by-name/page-513 Does anyone have a manual for this? Another question: I've read Andre***'s ZX91, and he uses 'Word Sinc II (P. Hargrave Nanaim)'. Is this availab...

Look like you are trying to create the same as I am.

I will have it as an external keyboard via expansion board however.

I have similar keys.

5V and GND only. For the rest: the thinner the better. I always choose minimum allowed (by my PCB manufacturer) thickness for all lines except power. GND normally is "the rest of the PCB" on top and bottom side as it can't be thick enough. power supply (12V, 5V, 3.3V etc) as thick as the design all...

kind regards Paul

I'm n00b with electronics. Do you mean all lines, or e.g. 5V and GND?
