Greetings from California!

Post by BarryBrown »

Hello all.

Like many of you, I was an 80s kid when I got my ZX81. I ordered the $100 kit, but they were apparently out of stock, so I received the pre-built. It's an issue one, but with straight (not curvy) traces. I recently brought it out of storage in order to resurrect it.

Last week I upgraded the RAM to 32K, installed the vla81, gutted the RF modulator, replaced the two electrolytic caps, and replaced the regulator with a buck module. Works great!

Still to come: upgrade the ROM to a big bang and get a new membrane.

At the moment, I'm enjoying re-reading the Sync magazines on archive.org.

I also have three TS1000 units. I'll probably upgrade one of them and leave the rest for spare parts.
