I believe that the memory images ARE the same as the paper tape images. The paper tape simply has all the bytes of the memory image which are loaded into memory by the bootstrap program that you toggle in. That is unless the original paper tape had its own more extensive boot loader as a preface to the data. If someone knows the format of Altair tapes, please let us know! The software to create the tapes from the bin image is trivial if I know the format. I would gladly produce tapes for anyone who wants them for just the cost of shipping plus a small bit to cover my paper tape cost.
The binary images are here:

CP/M and DOS...
click on "updated kit" and you'll get a ZIP file with all the BASICs in it. I'd like to get 4Kbas.bin, 8kbas.bin and exbas.bin converted. That would be great!
I can also make my own tapes (at 110 baud) but I have a question about the parity bit. My ASR-33 uses even parity, as usual. The first byte of exbas.bin is hex F3.
how would the paper tape have that punched? Would the parity hole be punched or not and when it's read back, would the interface throw away that bit?
