I believe he is.
He has a MegaCart.

If you have a spare 6560, try swapping it.

7402 can be replaced with 74LS02

Very impressive!!!

Try setting the boot delay for uIEC to become ready after reset.

I have found that 1581 also requires delay to be set for autoboot.

This was my favorite project for auostart cart (with ability to erase & rewrite)

My guess is that they were written by guy using 16K ram expansion and simply ported over to ROM.

They autostart from MegaCart menu

I placed an order yesterday, but I haven't received a followup email. Should I be concerned that my order wasn't received, or does it take some time to get a confirmation? Sometimes it takes a few days for confirmation e-mail. I assumed that one would pay when that email came, or does one pay when ...

Currently working on orders placed in late May 2011

It should be easy to open it with a thin blade (or something similar), forcing a bit on all four sides. Don't do the above, unless you wish to damage the case. There are two recessed slots on back of cart. Insert a small flat screwdriver into each of these and apply a slight prying force. This will...

There is a 1uf capacitor associated with 555 timer IC (which controls reset timing) within your Vic-20.

Thanks for heads up that site not online.
This will be looked into and problem resolved.

Who knows where it had been copied from (I just traded it with friends during datasette tape swaps).

I own the copy of City Bomber that was included.
It was tape based file and converted by NBLA000
