ZX80 RAM PACK DIY clone
Posted: Wed May 31, 2017 7:12 pm
Finished soldering my DIY RAM PACK clone today. But first, many thanks to Markus Brenner who made both the gerberfiles and 3D model of the enclosure.
I had started to draw the PCB myself, based on schematics and pictures I found on the web, but Markus was kind enough to send the complete gerber set to me.
Managed to pick up 20 pcs of the 2114 RAM chip via Ebay. No clue if they are working yet as I didn't have the guts to turn on my newly restored ZX80 with RAM PACK yet... Will try that after posting this.
Anyway here are some pictures:
Components soldered in place:
3D printed enclosure:
And fitted to my ZX80:
I am still looking for a (blue) connector with longer leads instead of the one fitted now. On the pictures I've seen the original connector was not mounted flush against the PCB. But it still fits onto my ZX80.
I bought an original RAM PACK via Ebay, which should arrive one of these days, so I can have a look at the rivets. They seem to be different from the ones used on the ZX80.
Anyway... found a small program to check the total RAM size. So time to power up...
