This brings to mind the C=Hacking article in one of the last issues on providing Burst mode support on a stock C64: "Burst Fastloader for C64 by Pasi Ojala, albert(a)cs.tut.fi" http://www.ffd2.com/fridge/chacking/c=hacking19.txt The description there involved soldering inside the box, but it could be done with an IEC pass through plug wired to a UserPort connector. Indeed, someone looking to do it wire-wrap style could make the IEC pass through with an IEC cable, with the user port connector secured directly to the cable ... a strain reliever secured to either end of the user port connector and a cut in the outer insulator to get at the two wires you need to tap into, enough slack on the short side to plug into the IEC port, enough slack between the strain relievers to get the electrical tape to cover the cut, and there's the el-cheapo Burstloader adapter. Given the generality of the serial daisychain and the speed of Burstloader mode, lots of things that we think of as cartridge devices could be done as IEC daisychain devices instead.

Oh, and plus have ROMs that already support Burstloader.

The right wire pair terminal block for a secure fit with the solder pins of a normal User port connector and you could switch between SP1/ CNT1 and CP2/CN2 just by attaching it to the right pair of pins.

Until 6 months ago I didn't have any form of expanded RAM; I had no exotic peripherals at all. But then, I'm coming out of hybernation. The problem with Z-80 is not many people have them. (And due to your statement, you can't use the argument that anyone serious has a CP/M cartridge. :p) I haven't studied the Z-80 for a decade, but I remember that its instruction set is clearly more powerful than the 6502. I hadn't tinkered w/ my 64 in forever, partly because everything on it was so cramped and inconvenient I just lost patience. I'm hoping to prove those can be brought down to size. |
