    Area 5150 for IBM PC 4.77MHz

    How about Olivetti M19 or M200? (Ok, unfortunatelly my M19 has only 360 kB floppy, no harddisk, and only green monitor..., My M200 has only black&white monochrome... - both with color monitor are very rare...), Olivetti PCS-86 is there, too, but it has VGA card. So I think I have to get out my...

    Area 5150 for IBM PC 4.77MHz

    Looks impressive, need to test it on real hardware... Anyone already tested it already on Olivetti M24 / AT&T 6300 ?

    Drop-in 8088 CPU Emulator for the IBM PC - MCL86+

    ... and Olivetti M24, M21, M240 (it must run stable at 8 and 10 Mhz bus clock!) An enhancemet to the NEC V20 / V30 instruction set also would be nice... Maybe also integrate 8087 emulation?

    Using Adaptec SCSI card, MSDOS 6.22 fails to partition (FDISK) and format SCSI drive

    I am currently quite confused... aspi2dos is not a driver for logical drives/partitions. aspi2dos (like aspi4dos) is a hostadapter driver (for 152x, 1502, 1505, ..., like aspi4 dos is for 154x and aspi7dos is for 174x and 274x hostadapters, aspiedos.sys for the 294x hostadapters) which provides...

    Olivetti Programma 101 documentations and experiences.

    Hello, I got P101. Later this year I will try test it (need power cable and fan rubber belt first). For this kind of historic moment I would love to have some more documentations for it. 23.07.2022 19:19 6.495.083 contenuto schede.pdf 23.07.2022 19:19 448.393 ISTRUZIONI...

    Using Adaptec SCSI card, MSDOS 6.22 fails to partition (FDISK) and format SCSI drive

    I think it could be one of the following issues: a) IRQ, ROM-Adress, IO-port of the 1522 is shared with other hardware. Solution: See which of the ressources they are, try to avoid the conflict. b) the harddrive is broken. See attached LMSCSI, this benchmark tool can access to raw SCSI harddisk...

    What I learnt putting a (Blue)SCSI in an IBM AT (5170) With Adaptec AHA-1520

    The 154x are that fast in DOS as they support DMA. 154xA/B 2 MB/s, and 154xCx can reach 8 MB, depending on drives, and it is better to have a 486 to reach that speed.

    What I learnt putting a (Blue)SCSI in an IBM AT (5170) With Adaptec AHA-1520

    I potentially have an explanation why the disk is slower that way: When it is served by the SCSI bios, the BIOS code is executed from a slow EPROM chip which has only 8 bit data lines. When the drive is served by ASPI2DOS, ASPIDISK, these drivers are sitting in "fast" 16 Bit DRAM. Mainly the...

    How to setup Word 5.5 correctly on an Olivetti M24?

    Yes, you can download it at microsoft.com, but only english, not german version, and that english version at MS misses a lot of printer drivers... I have created new setup packages by mixing files from different sources...

    How to setup Word 5.5 correctly on an Olivetti M24?

    Word 5.5 (and 5.0) supports the Olivetti M24 / AT&T 6300 640x400 graphics mode. I tryed that recently and I was disappointed, it looks like that graphics mode driver requires to have a machine with GO329 / DEB (Display Enhancement Board) to support 640x400 in 16 colors. If I install Word 5.5 on...

    Adaptec 1520 in IBM AT (5170)

    ASPIDISK.SYS is for harddisk drives. And it depends on what controllers you have. For example if you have Adaptec 1542A and you have harddisks on ID 0,1 2, 3, then it's BIOS only assigns ID 0 and ID 1 drive. ID 2 and 3 is not assigned by 1542A BIOS. For ID 2 and 3 you need to load ASPIDISK. If...

    Adaptec 1520 in IBM AT (5170)

    Check with your DOS boot disk a) first partition is active, see in fdisk b) harddisk has master boot record, write one with "fdisk /mbr" c) first partiion has bootable files (io.sys, msdos.sys, command.com), run "sys c:"

    Adaptec 1520 in IBM AT (5170)

    That's wrong... Adaptec provides two kinds of drivers in it's EZ SCSI packet. 1. Controller drivers, like aspi2dos, aspi4dos, aspi8dos, ASPIeDOS, etc. They are specific to the SCSI controller and they provide an ASPI interface for the drive drivers. 2. drive drivers, like ASPIDISK, ASPICD...

    Adaptec 1520 in IBM AT (5170)

    Besides aspi2dos.sys, did you also load aspidisk.sys?

    Struggling to identify motherboard. No manual.

    In these times, Foxconn only was the maker of the slots, sockets, connectors and things like that.

    Testing/Repairing ST's

    Yes, that is normal and the memory is detected as well. You found it by yourself, you have to start it before the desktop is started, otherwise it can not install/enable it. AutoSwitch Overscan is even more powerfull in monochrome monitor, you allmost get 800x600, to be exact, up to 762x576...

    Testing/Repairing ST's

    Yes, it has AutoSwitch-Overscan, and it has memory extension. That is definitive a machine which has been expanded not for gaming, but for serious work. To profit from that you need a hard disk or a flash based alternative (UltraSatan, CosmosEx, ...) to be able to install the Overscan driver and...
