Yesterday we moved the cabinet from my gameroom to my cellar, I'm really excited.

[level42]

Please tell me you didn't find any worm corpses at the bottom of the oven......

But.......I do dry electronics after I washed it .....like 6100 PCBs

[Wurstkopp]

Thank god no, it seems they're all dead. But to be sure I'll paint the wohle cabinet with poisonous wood hardener today.

Meanwhile I had time to build in the Hantarex monitor and power up the pcb for the first time. Seems like a nice fuckup of the 4116s.
But I'm glad there's at least some life. PSU is working and supplies all the voltages, sound board seems to work too. I ordered 24 new 4164 RAMs, building the power adaptor meanwhile.

[level42]

Yes 4116 to 4164 is always a good idea

[anunaki]

are these interchangeble? The datasheet looks isn't 100% the same

edit: googled it, pretty easy mod it seems

you have to mod the supply(connector) -  the 4164 does not need the -5v and +12v...

i just ordered a very very big stock of 4164 rams (1000 pce).. so if anybody needs some

[level42]

No and yes.

The big advantage is that the 16's need three voltages and the 64 only one (+5V).

You need to do some slight modding to use 4164s in places where 4116s used to be. Sometimes it's pretty easy f.i. with Williams boards using a special adapter (or just modding it yourself).

Actually.....the biggest advantage is that 4164s last a lot longer than 4116s.....the voltages are just another advantage

I've used a single 4164 as a replacement on an Atari 800 RAM card succesfully too, just need to reroute some pins.

This is what you need to do if replacing a single chip:

thanks for explaining and sorry for the hijack

[Wurstkopp]

No problemo, it's interesting.

Well, now it's payback time! I grabbed the most poisonous stuff I could get my hands on, the next harder stuff would be Agent Orange.
Here's the empty cabinet and the wood hardener:

I swear to god I could hear the worms scream!!

[level42]

Waaaaaaaahhhhhhhh......gives me the creeps !!!
