Some people had a c128 mostly used as c64-with-tape (eg. in Europe).
Then people would eventually buy a disk-drive, a 1541.
On c128 , 1541 is driven as a slow IEC device.
According to (https://www.lemon64.com/forum/viewtopic.php?t=52439) c64 could not solve it because board-mishap.
That did not befall c128, it has the CIA wired up to the IEC bus.
The following remark makes me wonder:...is it possible to program the CIA in c128 to use its serial-bus-connected-shift register with the 1541's 6522 like suggested above?
I DO recall there was a turboloader made by Bob Skyles, formerly from Commodore. (Skyles Electric Works). Since the shift register bug was a bug at the RECEIVING end, and the C64 had a fully working shift register, Bob made a turboloader using a 6522 shift register in the 1541, and a connector on the user port, in conjunction with a replacement ROM in both, to speed up downloads. I'd love find one. (I saw one, in the flesh, here in Australia, back in 1985)
(can the 1541's VIA even "see" the shift register in the c128 CIA ?)
