The only difference between drives is that an RL02 has an additional bit of track difference register logic over an RL01. (I think 10 instead of 9.) The -11 controllers allow a "mix and match" system, but the -8 does not. I presume that the RL8A sets up the bit that would be usefully programmed in the RL02 situation for the benefit of the RL01. Proper settings could be something like: 1) Always 0 2) Always 1 3) A sign extension of the neighboring bit 4) Some form of even/odd parity Thus, RL01 software may misbehave when the DIP switch is thrown for RL02 usage, while RL02 will only work if the switch is thrown. Presumably, if we knew what to set the "extra" bit to, the existent software could be made to work without regard to the DIP switch, and a mixed system could then be possible. Moreover, the DECmate I supports the RL278 option, and lacks this switch altogether, specifying only RL02's be connected. If the "offending" software can be identified, then the DECmate I could also support an RL01 or mixed 01/02 systems. cjl Summary-line: 7-Nov bqt@bern.docs.uu.se #Re: RL8A Received: from ELI.CS.YALE.EDU by BUGS.SYSTEMSY.CS.YALE.EDU via SMTP; Sat, 7 Nov 1992 06:12:00 -0500 Received: from life.ai.mit.edu by eli.CS.YALE.EDU via SMTP; Sat, 7 Nov 1992 06:11:56 -0500 Received: from sunic.sunet.se by life.ai.mit.edu (4.1/AI-4.10) id AA28700; Sat, 7 Nov 92 05:38:16 EST Received: from Bern.DoCS.UU.SE by sunic.sunet.se (5.65c8/1.28) id AA13170; Sat, 7 Nov 1992 11:38:12 +0100 Received: by Bern.DoCS.UU.SE (Sun-4/75, SunOS 4.1.1) with sendmail 5.61-bind 1.5+ida/ICU/DoCS id AA05919; Sat, 7 Nov 92 11:38:11 +0100 From: Johnny Billquist Date: Sat, 7 Nov 92 11:38:06 MET Reply-To: bqt@minsk.docs.uu.se To: Charles Lasner Cc: pdp8-lovers@ai.mit.edu Subject: Re: RL8A In-Reply-To: Your message of Fri, 6 Nov 92 22:18:56 EST Message-Id: From: Johnny Billquist Date: Sat, 7 Nov 92 11:38:06 MET Reply-To: bqt@minsk.docs.uu.se To: Charles Lasner Cc: pdp8-lovers@ai.mit.edu Subject: Re: RL8A In-Reply-To: Your message of Fri, 6 Nov 92 22:18:56 EST >As Johnny Billquist points out, there is a DIP switch on the RL8A for >changing over the RL8A to control RL01 or RL02, not both. > >The only difference between drives is that an RL02 has an additional >bit of track difference register logic over an RL01.

The controller can take a mix fof RL01 and RL02, some software sets the high bit of the track, though, which is not appreciated on the RL01... >cjl Johnny Billquist || "I'm on a bus CS student at Uppsala University || on a psychedelic trip email: bqt@minsk.docs.uu.se || Reading murder books pdp is alive! || tryin' to stay hip" - B.

I have the BIN and RIM loaders, so, what I need is software in the BIN paper tape format (can anyone explain that format in detail, also) that I can get into the -8/L by toggling in the RIM loader, loading the BIN loader, then loading the "application". I suppose the thing to do is read the software from tape into a machine connected to the net, uuencode it, and mail it to me (just tell me how to convert it back into the sequence of bytes I can punch onto a paper tape). Of course, if anyone wants to dispose of -8/L interfaces or expansion core, please let me know! (I have rk05, pc-04/05, rl01, but no interface to the -8/L for them).
