Message-ID: <53EE4244.3040702 at attglobal.net> Content-Type: text/plain; charset=utf-8; format=flowed I've imaged a little stack of Displaywriter 8" disks and am starting in on filesystem organization. With an EBCDIC filter I can see the data plain as day. I've also got experience stitching together the DisplayWriter files that come from the DOS-based system, so if I could get the file allocation scheme figured out and lift off whole files from these disk images, I bet the same conversion code would work on the resulting data. I've browsed the manuals on Bitsavers, but of course IBM never intended their users to actually look at the bytes on the disk. So none of the information was geared towards revealing the file allocation secrets. Is there any reference material out there to help me decode (or find) the file allocation structures? - David ------------------------------ Message: 3 Date: Fri, 15 Aug 2014 12:34:40 -0500 From: Jerry Kemp <other at oryx.cc> To: General Discussion: On-Topic Posts Only <cctech at classiccmp.org> Subject: Re: old Sun metal kbd is GONE!

What's the "PTR:" device in this case, the console input? If so, you may be able to use reader run as a CTS indicator somehow. What's happening here is that PIP fills a buffer, then initiates a write via the TD8E onto the tape. Until the TD8E driver gets done positioning and writing, PIP is no longer in control and there's nothing reading from the input device. You've got to figure out how to suspend feeding data until the device handler returns and allowing PIP to run. It doesn't matter what baud rate you use given that it can take minutes for a tape I/O to complete. You will lose characters. I've managed to make serial upload work with "echo control": send a character, wait until it's echoed before you send another. Agonizingly slow. I'd suggest looking into the Kermit-12 docs and uploadable files. There's a way to bootstrap yourself over a serial device to a working Kermit. -Rick ------------------------------ Message: 6 Date: Sat, 16 Aug 2014 21:50:44 +1000 From: Nigel Williams <nw at retrocomputingtasmania.com> To: "General Discussion: On-Topic and Off-Topic Posts" <cctalk at classiccmp.org> Subject: Re: Displaywriter 8" filesystem?

Any idea what this error means? Incidentally, I used to use a software package called UNIRAS to do graphics on VAXen, does anyone know if it is still possible to find this software?

I'm sure you could find more if you hunted around. It's all the same op-codes and addressing modes; except in the currently shipping 65C02(S) they added a few instructions and filled out a few pins that aren't present in the earlier revs. So if you are working with an older 6502, use the older datasheet; if you just went out and got a brand new one from WDC, use the new data sheet. Other than that, any old 6502 data sheet is about as definitive as it gets :) If you are talking about assembler macros and stuff like that, I'm sure there are as many variants as there were assemblers, little to no standardization there from my experience, LOL. But regardless of the computer, it's the same 6502 and same op-codes underneath. I'm in the middle of doing a little 6502 SBC right now so I've been poring through these publications quite a bit over the course of the last few weeks ;) Another neat reference is 'The 6800 Processor' by Jack Quinn, I know it's not 6502-specific but the two CPUs were so similar, there's a lot of relevance... nice book discussing the programming model on these CPUs including a very thorough treatment on hand-assembly which I found to be quite educational.

The 6800 and 6502 are not op-code or pin compatible. I just referenced the Quinn text because I think it's pretty good for the high-level concepts and I'm not aware of any similar publication dedicated to the 6502 specifically.
