If anyone is contemplating adding an inexpensive hard disk to a floppy only CP/M system, they might want to consider the following. A company by the name of Advanced Concepts in Boca Raton, FL, provides a very good solution. All you have to do with one of their systems, is pull the Z80 out of your system, insert their daughterboard into the socket where it came from, and put the Z80 back in a socket on the daughter board. Then an installation program is provided that places a boot image on the hard disk, and you are all set. Your system boots initially from floppy, then by running the hard disk install program, the hard disk is brought on line. I have recently installed their system into my Televideo 803, and I can say the hardest part was opening the system to pull out the Z80. It is worth noting that if there is not enough space to take the daughter board inside, extension cables are available, so that the board can be placed outside your system enclosure. Their address is: Advanced Concepts 8926 South West 17th St. Boca Raton, FL 33433 +1 (407) 482-7302 Disclaimer: I have no connection with Advanced Concepts, I am just a satisfied customer. -- dg@lakart.UUCP - David Goodenough +---+ IHS | +-+-+ ....... !harvard!xait!lakart!dg +-+-+ | AKA: dg%lakart.uucp@xait.xerox.com +---+

The ones I saw worked pretty well (and this was on a machine with just about the worst digital system ground you can imagine - although a lot of Z80 designs seemed to attract similar layout flaws). One question, though: What does it cost? -- William Swan ..!tikal.Teltone.COM!sigma!bill # +-----------------------------------------------------------------------+ # |Innocent but in prison in the State of Washington: | # | Debbie Runyan - Sentenced to 13.5 years for a crime not committed, | # | incarcerated 01/1989, scheduled release 07/2002. | # | In now: 0 years, 0 months, 1 week, 5 days. | # +-----------------------------------------------------------------------+

I bought just the controller card and cables and software for about $200 If you add a hard disk, a powersupply and enclosure, I'd guess that the cost would rise to no more than $500, possibly less. I don't actually know, because I wasn't interested in a PSU or a disk (I already had both). I'd say give them a call, or write. If you DO phone, don't be put off if it sounds like a private residence, it's a small company, and I think they don't have a proper switchboard operator. Whoever can get it answers the phone. -- dg@lakart.UUCP - David Goodenough +---+ IHS | +-+-+ ....... !harvard!xait!lakart!dg +-+-+ | AKA: dg%lakart.uucp@xait.xerox.com +---+

Same deal with a Z80 host card and connected to WD card. Runs up to 2 64M hard drives off a single card. I don't remember the cost; in particular, the hard drive card side (not host adapter) varies depending on availability. -Mitch
