4MB RAM UPGRADE KITS PROGRESS

[exxos]

I have placed an order for 100 of these boards to be built and assembled. The costs of this was well into four figures but I simply do not have the time to mess about assembling these any more. So it is just a matter of waiting for them to arrive now and I will of course be testing each one before they are added into my web shop.

They look almost identical to previous boards. I have tweaked they layout a lot to hopefully improve reliability of assembly. Last time I ordered some boards about 40% of them did not work and I had to repair them. Even so there was still a few boards which I was unable to repair. In any case, I should be able to get around 50 of these kits in my store again in a few weeks time.

Small update - my PCB guy said boards will be shipped this week. As its the weekend soon, likely arrive mid-next week. Though please note I still have to test a few boards before putting them into my store

Did they come in yet, lol. I'm needing a 4m upgrade for my STFM bad, lol.

Testing some out right now

I am also soldering on the connector and capacitor on the shifter adapter boards as a lot of people have troubles soldering the connector. I am continuity checking the boards the shorts and connections of my multimeter, but I would suggest people doublecheck this just in case

I am hoping they will be about 10 boards stock over the weekend

The remainder of this batch of 100 will be in stock over the weekend.

It took some days to test all 100 RAM PCBs out there was a few which needed fixing, but not many, in the end only two failed out of this batch is the best I have ever had

I have spent the past couple of days soldering the SMT connector on the shifter PCBs. I can only really visually test these, but I have tested a few random ones of the multimeter to check continuity and all the board seem okay. I soldered these as people were really struggling with this part, to they are now supplied soldered at no extra cost.

Hopefully I will not have to produce these again, as they take enormous amounts of time and cost well into four figures to produce.
