SD2IEC PCB arrived

Jeroen Leave a comment

2 weeks ago I designed a PCB for my SD2IEC.
Last Friday I received them in my mailbox.

I took the schematics of ShadowWolf and used the online design tools on www.easyeda.com to draw the schematics and design the PCB.

The result is found here and I ordered an prototype ($10,- with shipping).
The SD2IEC uses a micro SD module with build in voltage converter.
The only signals missing from the SD module are Card_Detect and Write_Protect.

I routed those signals to a dip switch so I can still control these signals.
The Card_Detect signal is also routed to the SD module header, so I can modify the SD module to add this signal.

If this proto type works, I will be updating the PCB with RTC and LCD, and will move the micro SD to the main PCB.

Vic 20

This weekend I bought some hydrogen peroxide gel from a local store.
And started to retrobight the top covers of an Amiga 1200, C128 and a vic 20.

First I cleaned the case parts very good with a toothbrush so all dirt is gone.
Then I used a brush to “paint” the case parts with the gel, and wrap them in with plastic foil.

After this I left them for some hours in the garden.
It was a warm day, but the sun did not burn as there were a lot of clouds.

After some hours I cleaned the gel from the cases and was surprised by the result.
I will do it another time as I noticed I missed some spots.
And then I will also do the bottom part of the case.

Today I collected a VIC-20.
I swapped 2 Commodore 64 computers for one VIC-20.

The VIC-20 is the predecessor of the Commodore 64.

The VIC-20 specs:
CPU MOS 6502 at 1 Mhz (1.108404 Mhz for PAL and 1.02 Mhz for NTSC)
20Kb ROM and 5Kb RAM (expandable to 32Kb)

I’m not sure what I’m going to do with it yet, it’s in working condition but I’m thinking about adding Jiffydos and a internal 32Kb ram.
