This is because the ZXmaster instance is not active during ZX80 running (same as ZX81 in FAST mode, wouldn't be able to load with DS-L during FAST mode). I will try to get a workaround in a further release. At least to load a progra...

Re: Use 4 small EEPROM instead of 1

Well this is in general easy. An 8kByte E(E)PROM has 13 address lines (A0-A12) while the 32kByte requires 15 (A0-A14). You can wire all parallel except the /CE input. You need than additional an address decoder like 74LS138 and feed A13 and A14 to A+B input, connect C to GND and G1 to +5V and connec...

Re: ZX81CCP

Well some people told me, that LOAD and SAVE does not work with the current release of ZX8-CCB-SYNC. And that was correct, I tested LOAD/SAVE with a CRT monitor here and that didn't have sync problems. So now LOAD and SAVE are supported as well on LCD or Plasma TV and the screen pattern is mixed wit...

Is that bluish green colored ZIF socket in that recent picture of yours a 3M brand or whatever?
It's a Textool. I prefer the model with round pins then and will buy one from next Mouser order.
I have another from Connfly which has same rectangular pins.

Re: ZX Max 48 PCB

As in the last time I got about 50% fake chips from China I am more careful now what I buy.
I prefer reliable sources. It's depending on the chip type.
The DS1302 I bought last time were not working or even crashing my system (different suppliers show different behavior).

Re: ZIF Socket and ZXmore

Are the contacts round or square ?
My sockets here have rectangular pins and do not fit into these precision sockets with round contacts.

Re: I could imagine this is how Iss. 1 boards were made.

But was fun, too. 8-)
Yes - we had more time in the past to realize those things.
And were able to charge more money for this work. ;)
