Look, I show you another experiment with my Dragon Lab-Cart.
I built a
new multicart for the
VECTREX based on my Dragon Lab-Cart.

It is capable of holding 27C128 (16 kbytes), 27C256 (32 kbytes) or 27C512 (64 kbytes) eproms.
The two blue jumpers are used to adapt the board to the eprom type.
Two switches put the cartridge into 8k, 16k or 32k banksize-mode. Most of the original games are using 8k. Homebrew games and demos often need 16k or even 32k, which is the maximum cartridge address range of the VECTREX. For example, a 2€ 27C512-eprom-chip can store two 32k-games, four 16k-games or eight 8k-games. The game is selected by turning the gray knob.
Cool
, I can check the latest demos now
. The zero injection force socket makes it easy to change eproms. One cartridge and a box of eproms is enough
. I'm really looking forward to check what's out there, concerning new software...

Additionally I put a speed brake onto the cartridge, which can be activated with the help of a 3rd switch, and which can be adjusted by turning a little wheel. It's simply a multivibrator pulsing the !HALT-signal.

I had to cut the board and reduce it's dimensions a bit.
I built the whole thing nicely into a modified Activision-shell of a dead Atari VCS cartridge. Ok, to make it fitting, that was quite some work to do
