Ärende: DOS-diskett

Hej igen! Jag skall förtydliga! Jag har en ABC802:a med flexienhet. Samt en ABC80 med en ABC832 flexienhet. Jag skulle vilja få tag på en system diskett till dessa datorer. Är det någon som har det? (lätt fråga eller?) Om ni har en sådan men ej möjlighet att kopiera den kan jag göra detta. Jag är villig att ge ersättning för detta. MVH Per Vallgren.

  Jag är helt med på detta. Ville bara förklara hur det funkar. Jag fixar kopior så snart jag får fart på 802:an (ska igång i helgen hoppas jag) -- Skickat från min Android-telefon med K-9 E-post.

  Systemfiler för UFD finns här http://www.devili.iki.fi/pub/Luxor/software/ABC-klubben/abc80/systempr/ufddos/ Det är inte Telediskformat på dessa filer. Det kliar i fingrarna att läcka nyheten att Robert kopplat ett litet SD-minne till ABC80! Den senaste månaden tog vi upp projektet att koppla PIC32 till ABC80. Nu är han nog bortrest men här är ett av hans senaste mail med en videolänk. Ganska coolt va? :-))) Hälsn. Anders.J

    Det är till UFD-DOS för ABC80. Skulle inte tro de fungerar på 800 (men jag kan ha fel...) -hpa -- H. Peter Anvin, Intel Open Source Technology Center I work for Intel. I don't speak on their behalf.

  *Vilken* flexenhet till ABC802? ABC834 (som är kompatibel med 832:an)? För icke-UFD-DOS kan dessutom DOS- och kontrollerversionen ha betydelse... lyckligtvis fixade dem *det* problemet i UFD... -hpa -- H.

    Hi, The Luxor computers should be fully operational in MESS except for the exceptions listed below: abc80 - cassette read - floppy (slow controller requires Z80 RDY emulation which we don't have yet) abc800c - cassette read/write abc800m - cassette read/write abc802 - cassette read/write abc806 - the graphics PROMs are not dumped (RAD, HRU1, V50) abc1600 - hard disk SASI bus card is not emulated properly due to lack of schematics - virtual memory mapping does not work as described in preliminary service manual abc9000 - no ROMs have been dumped I'm currently looking for the following to complete the emulation: - ABC800C/M service manual - dumps for ABC80 peripherals (80-column cards, BASIC V1, etc) - dumps of the ABC806 graphics PROMs - dumps of the ABC9000 computer ROMs - information on the ABC1600 virtual memory mapping - schematics for the ABC1600 SASI card (Luxor 4105), or maybe borrow the PCB so I can trace it out with a multimeter? If anybody could help with these, det vore jättebra :-)

      Any specific reason you insist on using the slow controller for ABC80? There were so many controllers and floppy disk solutions for ABC80 (there were at least three vendors - Scandia Metric's FD series, Luxor's ABC series, and Tranfor's Datadisc series, and of these Luxor's was probably the least popular for ABC80) that I don't think anyone cared about the exact timings. BASIC v1 being the one that is generally known as "checksumma 11273" I believe. The 80-column card changed only a handful of memory locations when invoked, unfortunately I only have the patch for checksum 9913 (BASIC v1.02). Which exact patch depended on the exact 80-column card you used; there were at least three variants from I believe two different vendors, one (Gejo) which put the extra RAM at 7400h-77FFh (29696) -- early versions 7800h-7BFFh but that conflicted with the printer -- and one (MyAB's TKN80, probably the more popular) which put it at 5800h-5FFFh so that it would be contiguous (5C00h-5FFFh being a shadowed to 7C00h-7FFFh) but that caused problems with other peripherals... The only difference between the three models as far as the BASIC ROM is concerned is the address table at address 884 decimal (0374h) which contains the start address for each of the 24 lines. The additional changes for checksum 9913 were: Address Value --------------------- 0x01d8 0x50 0x0211 0x50 0x024e 0x50 0x026f 0x4f 0x02de 0x50 0x033c 0x50 0x22f2 0xa0 My FPGA model mimics the later Gejo version (7400h). -hpa -- H.

        It's the only controller I have schematics and ROMs for... I have a dump of the FD2 controller but no schematics. So the 80-column cards don't have a font ROM at all? Do they use an MC6845 or TTL logic for the display? From: H.

        I suspect they use the same font ROM as the motherboard, either their own copy of it or possibly (at least in some variants) the actual same chip. -hpa

        Hi, I have found the schematics to Luxors controller card "Styrkort 55 21046-11/21/41". This was used in ABC850/Tranfor DataStore and stand alone with all floppy drives together with ABC80x. I also have ROM dumps for this card. I can put the schematics in the scanner if there is any intensest in it... /Anders

      Does MESS allow accessing the host filesystem outside the simulation? If this is allowed but not supported, I might be able to help write some support... -hpa -- H. Peter Anvin, Intel Open Source Technology Center I work for Intel. I don't speak on their behalf.

      As luck would have it, I was hacking my utility for reading and writing ABC filesystems, and I actually found I have the ABC80 BASIC v1 on a floppy. File attached; the checksum is 11273 as it should be. -hpa -- H. Peter Anvin, Intel Open Source Technology Center I work for Intel. I don't speak on their behalf.
