You can, however, determine if the program is currently running AC> on a Rainbow or an IBM and remap your BIOS calls based on that. DecComm, as the name implies, pertains specifically and exclusively to DEC computers (the Rainbow, in particular) and has nothing to do whatsoever with IBM PCs and/or their BIOS. It's what is known as a communications FOSSIL program, which is a class of TSR system programs that adapt an application program to a specific computer architecture. DecComm was written by Vince Perriello, and I am (still) hoping to get a response from him on this echo. - --- msged 1.99L MSC * Origin: Silver Bullet - Silver Spring, Md. - 301-622-2247 ------------------------------ Date: 07-18-90 (07:35) To: CHRISTOPHER WROTEN Subject: RAINBOW INFO From: PAUL OLSON Christopher, The Rainbow 100A is expandable to 832Kb, while the 100B is expandable to 896Kb. The difference is the amount of memory DEC placed on the mother board. The 100A had only 64Kb, while the 100B had 128Kb. The easiest way for you to tell if you have an A or a B is to look at the startup menu. If there is a W option for booting off the hard drive, it is a 100B. You can expand your memory by buying chips for the memory board in the machine. From the sounds of it, you have the memory expansion board with socketed chips on it. If so, all you need to do to upgrade is to buy the proper chips (256x1, I think, but double check; it has been a long while since I bought chips for the 'bow), pull the old 64Kb chips out of the board, insert the new chips, and flip the proper dip switches on the board. It may also involve a software setup in the setup screens. (Boy, it has been a _long_ time since I looked at this stuff!) I suspect you have a 100B with the memory board with the socketed chips. The only way to tell which memory board you have is to pull out the mother board (by removing the system unit cover, unscrewing the large black screws on the back of the system, and sliding the mother board out), and removing the memory board from the motherboard and looking at it. Be VERY careful about static shock to your boards!! Also, be prepared to support your motherboard from underneath. It is a big board. The memory board is located in the middle of the motherboard. As for disk drives, your best bet would be to buy a disk controller and cables from a used equipment dealer, and a hard drive from a mail order house. You can call Newmann computers in Ann Arbor, MI, or Eustace Enterprises in Orlando (?). I don't have the numbers with me. Alternatively, you can also contact the Internation Rainbow Users Group for more information. Their number is 618/632-1143. Caroline Mack has more contacts than anyone I know. My own system has a MicroCHS dual hard disk controller and a Seagate ST-225 20Mb hard drive. I don't know the availability of the MicroCHS and its associated software as the manufacturer and the distributor both went out of business. A single drive DEC controller should work just fine for you. You will also want to download WUTIL from your favorite BBS system. Other resources include CompuServe which has a good DEC Rainbow forum. Unfortuantely, they charge for connect time. If you have any more questions, just yell. Next time I'll try to answer from home rather than work. I don't have any of my Rainbow info at work.

Two additional comments: - - some Rainbow software is available from the INFO-DEC-MICRO file archives at Carnegie-Mellon Univ. For those with anonymous FTP access, connect to DRYCAS.CLUB.CC.CMU.EDU, switch over to [.INFO-DEC-MICRO], and download to your heart's content. And at no cost! - - there is at least one bbs which is not part of Fido/Opus carrying Rainbow files. It's Penn's Landing, +1 215 898 8511, 8N1. You should check with George Dahlco about others.
