SMART RAM: a versatile RAM expansion cartridge up to +37k
.
SMART RAM: it's arrived!
1) It's a "whole RAM": all areas that a VIC can select from a cartridge are covered by this RAM expansion
2) It's easy: a simple 3-position selector lets you choose the configuration as follows:
--- side A) +24k Basic (+8k BLK5, +3k low ram, +2k I/O areas) [total of +37k]
---central) no expansion
--- side B) +3k basic low ram (+2k in I/O areas) [total of +5k]
Note: the 3 positions represent all the three possible configurations that the VIC20 operating system recognizes.
3) It has a RESET button for easy restart of the VIC without any powering off and on again
4) Its shape simplifies the removal and dimensions allow it to be hidden inside the cartridge door. It can also be assembled inside a common cartridge shell by simply remoting the button and the sliding lever (they do not need to be unsoldered to remote)
5) Not expensive at all!
Good,
but MCes is not happy if a "modder/hacker's hole" is not present: SMART RAM is easy for those who want it to be easy, but for all the others....
6) Simple MODDING to deselect specific areas permanently (removing the related DESOLDERABLE JUMPER) or temporarily, by soldering a DIP-SWITCH (you have a soldering iron, haven't you?)
7) simple HACKING to reconfigure the action of the slide lever selections
(if you happen to have also some wires and diodes at home)
Diodes: BAT85 suggested, but also 1N4148 will work

Re: SMART RAM: a versatile RAM expansion cartridge up to +37k
Now the prototype batch (fingers not gold plated), and the first "gold finished" batch, are ready.
They will be soon for sale also on other places, and eventually the proto batch will come to exhaustion (no other prototype batch will be produced).
Boards will be assembled starting from the mid of September, but it's possible to book them from now on (write in this thread or PM).
Prices (without shipment and eventual PayPal fees):
10€ 1x smartRAM "proto board": no gold plating (HASL finishing) and only 9 removable jumpers...
15€ 1x smartRAM "gold finished"
20€ 1x smartRAM "gold finished" + 1x smartRAM "proto board"
25€ 2x smartRAM "gold finished"
Combined shipping if you purchase other products of mine.
Thanks for your interest!

Very good! I like it! Could be used with a softimage of Minimon as one cartridge solution!
Payment options?

Can write be disabled to defeat ROM copy protection?

@NOIZER: paypal will be good.. PM me.
@CHYSN: "SMART RAM" was developed to be used in the simplest way, if you want also the BLK5 write protect also this is still available:

Re: SMART RAM: a versatile RAM expansion cartridge up to +37k
I ordered the SMART RAM. What address does the 2K I/O RAM start at?

Re: SMART RAM: a versatile RAM expansion cartridge up to +37k
I'm interested too
Re: SMART RAM: a versatile RAM expansion cartridge up to +37k
The 2K I/O RAM starts at $9800.
The 1K at $9800 is usually called I/O2 and the 1K at $9c00 is called I/O3, see here:

On the use of the I/O area, the information in the sales thread of my old ram + 37k expansion could be interesting (read the first two pages ...)
