Re: VIC-REL Clone with Case

Nice name for a company... Thanks! It's like Mastertronic, but on a dorkier level. How much power can those relays handle? The max ratings are 1 amp and 100 volts, but you'll probably want to keep it under that. Is the software still available somewhere? The "software" is just two POKEs r...

VIC-REL Clone with Case

Hello all, I've been working on more hardware projects for my VIC. This time I've got a clone of the VIC-REL relay board. I've mounted it in a nice two panel laser cut acrylic case, and it has a label on top with the pinout for the terminals. I've made six and am keeping one for myself. I'm asking $...

Re: Mini 32K RAM expansion hides in your cartridge port.

How do i load from a cartridge and then play from RAM? Tokra is correct. You will need to load a cartridge image from a storage device (disk, tape, uIEC) into RAM. I have a uIEC/SD . Here's how I use it to play cartridge games. 1. On my PC, I download cartridge images from zimmers or elsewhere and ...

Re: Mini 32K RAM expansion hides in your cartridge port.

Thanks for the review, Robert! I chose the right-angle reset button so when you press it, it pushes the cart against the back of the cartridge connector instead of down possibly shorting the soldered pins connections on the bottom of the board with the inside of the VIC. I'm curious. Do you or anyon...

Re: Mini 32K RAM expansion hides in your cartridge port.

Thanks everyone! I'm glad you are enjoying the boards. The new batch came in tonight and I've soldered them up and tested them.

Here's the new listing: http://www.ebay.com/itm/331629073207

Re: RS-232 Read/Write from Machine Language

Here's my complete program, the setup of the serial port is near the start. I tripped over a 'feature' that BASIC works around. The OPEN call returns with Cb set and $F0 in .A on success , it's a side-effect of calling MEMTOP at the end of OPENRS... Any examples that can read/write at 9600 baud wou...

Re: RS-232 Read/Write from Machine Language

KERNAL calls are fine. In fact preferred, I think. I want to keep the code small. 192 bytes in the cassette buffer.

RS-232 Read/Write from Machine Language

Are there any source examples out there for reading from and writing to the RS-232 port from assembly?

RS-232 empty string vs. zero byte

Hello all, I'm playing around with the VIC's RS-232 port. Most examples do something like this: 10 open2,2,3,chr$(8)+chr$(0) 20 get#2,c$:if c$="" goto 20 However, when I do that, any zero bytes sent to the port seem to be skipped. Is there a way to tell the difference between an empty stri...

Re: Mini 32K RAM expansion hides in your cartridge port.

It makes me very happy to see that someone has done something with the info I once posted! Nice to see a proper implementation, good work. The reason I made my expansion internal was to be able to rip cartridges and never have to remove the expansion. Thanks Adam! I must say... using the priority d...

Re: Mini 32K RAM expansion hides in your cartridge port.

Well, I can confirm the "feature" exists. I had to haul a 1541 out of storage to test it. I've really have gotten used to my uIEC. There is a simple workaround for these cases. Either power cycle your drive, OR... After turning off the VIC, hold down the cartridge's reset button for a few ...
