So one RAM and one Flash Memory chip for upgrading my Z88

512K SRAM internal upgrade
512K Flash Memory internal upgrade

I knew they looked familiar, just couldn't think why.

Well that is the RAM chip (front and centre) desoldered. I'll do a separate topic on this Z88 upgrade.

Looking good so far.

Looking good so far.

I have a sort of love / hate relationship with these types of upgrades. They are pretty simple to do but half the time I end up plotting how to build a board with a SMD Flash ROM and RAM chip combined that would just plug-in with a couple of fly leads.

LBH These things don't always work out as planned, as long as it works in the end

That’s true. I did have a glitch before I started the upgrade and put it down to low batteries.

The LCD was all blue and after doing a hard reset the screen came up with the menu and low battery sign.

I then went ahead with replacing the RAM chip and am faced with the all blue screen again and hard reset doesn’t fix. Yes, I have used different batteries as well.

This, @rubber_jonnie you are right it’s not always as planned.

Damn, that's annoying, but I'm sure you'll figure it out. Reminds me I need to get back to my dead HX-20.
