I'm trying to get some software onto a tape for my pet. I have a 128 and a datacassette, and can read the pet tape I have, and I can load programs from it. I've tried the following program in c64 mode.
 
100 CIA = 56576:VIC = 53248:VRAM = 648:BSTART = 43:BTERM = 55:NMIVEC = 792
110 POKE CIA, PEEK(CIA) AND 252 OR 1:REM SELECT VIC MEMORY BANK #2 ($8000 - $BFFF)
120 POKE VIC+24, PEEK(VIC+24) AND 15:REM SET VIDEO RAM TO START OF BANK
130 POKE VRAM,128
140 POKE NMIVEC,193:REM POINT VECTOR TO RTI (DISABLE STOP/RESTORE)
150 POKE BSTART+1,4:REM SET START OF BASIC RAM TO $0401
160 POKE 1024,0:REM ENSURE BYTE AT NEW BASIC START - 1 IS NULL
170 POKE BTERM+1,128:SET END OF BASIC RAM TO $8000
200 POKE VIC+32,0:POKE VIC+33,0:REM SET BORDER/BACKGROUND COLOR TO BLACK
210 PRINT "{green}{clr}### COMMODORE BASIC ###"
220 PRINT " 31743 BYTES FREE."
230 NEW

This program sets up the 64 like a larger Pet, basic starts at 1025 and it's giving it 32k of ram. Can anybody modify this to reflect a 2001 vic with 8k of ram. Or is it ok the way it is?
 
I load and run this program, then load the pet prg from my uiec and then save to tape.
 
So far I've transfered space invaders and pinball fine. It this just fine for most pet programs, or is there something else I should be using?
 
Thanks,
later,

Auctions et al / WTB: 6550 Ram for Pet 2001
« on: March 18, 2011, 08:57 PM »
I just picked up a beautiful Pet 2001-8 that has a bad ram chip.
 
Does anyone have a 6550 or two they could sell me?
 
Thanks!

Ok, I'm an idiot. I was playing around with a user port interface I built and partialy unplugged it while my 128 was on.
The machine did a hard lock, and when I tried rebooting, the machine is dead.

Any suggestions on what to try or check?

I've got access to a 64 for parts, but not another 128.


Thanks,

I'm looking to add a internal wireless serial terminal server to my 128, it will need about 700mW of power.
I am using a 3.3volt regulator to power it, and was hoping to draw the input 5v from the computer.

Now my flat 128 power supply is rated for 4.3a on the 5v, but I've read that some are only rated for 2a.
(I figure the c64 is right out with a stock power supply.)

Can I draw the required load without hurting a standard supply?


I'm also running a uiec from Jim Brain internally already.

Thanks,
dabone
