Re: Building a NeoRam Ram expansion memory cartridge for the C64 computer

Post by banman »

About 3 days ago I received this delivery from JLCPCB.

I paid $30 AUD (shipping included with this price) for 20 HASL (hobbyist/prototype grade) boards. For a hobbyist like myself this is great value. They came relatively quickly considering I had them shipped economy. The package arrived in excellent shape thankfully.

I received.

5x Sidekick64 PCB'S
5x Sidekick64 to C16 adapter PCB'S
5x Neoram PCB'S
5x Vic 20 hyperexpander PCB'S


The Sidekick64 and Vic 20 hyperexpander PCB's were close to the 100*100mm size.
One can see the silica gel inside the hermetically sealed bags. I didn't get beveled/chamfered edges on the connectors because I could locate that option in the order menu. Next time I order I'll look for that setting.

Maybe someone can confirm this. When I used the Pcbway website I was quoted considerably more for the Sidekick64 and Vic 20 hyperexpander PCB's.

I also got a set of Neoram C64 memory card expansion cartridge PCB's as well as 10 units of HM628512
SOP 32 SRAM.

I used this supplier...

The antistatic package looks unbroken and the chips look like they are in reel/tape packaging. I have to admit that the seller l purchased the Cypress chips from didn't provide an antistatic package for the reel/tape of chips. I am hoping that I'll have better success than with the Cypress chips.

When I get a chance I inspect the chips to see how 'authentic' they look and try to fit them as carefully as l can to the JLCPCB boards.
