Hi James, Thanks for the reply It seems that alot of people are pointing thier fingers at the CPU or ROM. We tried (a friend and myself) resetting the CPU by...
Ye Gods!!!!! Even Dave wouldn't run a screwdriver across the legs of the CPU! It's a wonder the poor bloody 200 has not thrown in the towel, but it appears...
Whoa! The RAM chips in a VZ200 aren't on the motherboard and I assume a Laser200 to be the same. They are on a separate memory board, so there is no hacking...
When you turn on the power to most machines they usually do one of two things. 1. Hold the CPU reset or a halt line active for a period of time till the...
As long as you don't short to a voltage source you shouldn't be touching it won't do anything to harm the chip. At least not unless there is a static shock. ...
If this is a common problem with the 200 then that's what I'd look at. BTW, if the 200's RAM is on a daughter board, wouldn't it be easy to upgrade it to more...
Well... I purchased twenty of the buggers so if nobody else here did I have some... er... extras. That should be enough for 5 boards with 4 chips each. If I...

For people I've seen post to this list I'll sell them at about $2 per chip (gotta total my costs) + shipping. I won't be making money on them. If I put them...

Hi all, Remember a while back we were talking about a 6502 version of the VZ. Well I came across a picture of one and then promptly forgot the link. Anyway,...

Hi, I have a VZ200 I'm thinking about putting on ebay. I have modified it by adding a new RAM board so no RAM expansion module is needed, but I made the...
