IMSAI 8080

<> Firstly a CD player is not that easy to convert into a CD-ROM drive. My <> CD-ROM drive _is_ based on a CD-player, and I have the service manuals <> both for the CD-ROM drive and the player. The mods are not that simple < <I'm not talking about converting - I'm talking that in 25 years <still new drives will be available to read CDs - Maybe some kind <of hyper-DVD-super-ultra drives - but able to read 'regular' CDs. That may be longer than reasonable... I'd use say writable CDrom and if 9 years from now the ability to read that start getting scarce I'd use the next technology that is current then and copy to that. This would allow reading using available technology and also insure the data was fresh. FYI: checksums and various other means can be used to insure a file has not been compromized and also make recovery possible. < <> Secondly, where do I get a 78rpm record player these days (new, of <> course). Or a Playtape player. Or an 8-track cartridge player. Music <> formats do go out of production as well. Some do some don't and a few are easy to make. a player for 78rpm disks would be pretty trivial. Certain tape formats are fairly easy like 800/1600 bpi magtape. <shure ther will - I bet any money you want - or wait - I what <about my Pascal Microengine ? You'll get it if there is no new, <working, CD reading device availabe in 2023 :) It is necessary to look at the entire archival picture. copies of the eproms/roms PALs are only a peice, spares to reproduce them and the tools needed to insert code are also required.
