At 201212 I've assembled Searle Grant's Z80 SBC. Here is my (early) version. I describe it here , but looks like I'll have a separate page describing my work here.

Microsha (8080 based soviet computer) and it's Lianozovo FDC (floppy drive)
ROM (bios) photos of Microsha
ROM
(bios) fotos of Microsha's FDC . The ROM size is 2kb and it starts from E000, so the E800-EF00 photos seems to be
useless. You can (oh no, you - cant, but I - can ;-) ) boot it via G E000 and get a message "DOS 2.9\nNo DISK\nNO DISK\nA:". The
DOS is NOTHING LIKE CP/M, so the FDC is quite useless. And it does not require any "Boot Disk", all the needed things
are inside of ROM
Delta-S
Is well-known Soviet ZX-Spectrum clone,here is pinout
I do not own this computer any more (but know a person who owns it now)
It's written that pressing TOC key for 10 secs while power up does not lead to console on com port 1;
that's wrong - it DOES! So you do not need that weird 10 pin RJ-45 keyboard (HP-HIL or even not?)
UPD: That's true for "second generation" 715s.
I've soldered the connector of keydoard and mouse to 715/80. Here is as scheme by John Burns from www.unixnerd.demon.co.uk, great thanks to him!
Use hammer and screwdriver to jam the RJ-45 style port. It's correct name is TP10P10C , at 2012 it is on sale in ChipDip in Moscow.

This also should be true for 715/100 and 715/64 models
Runs: HPUX 10.20,11.11i,NetBSD and Gentoo (I've tried just to load the last two ; they loads)
I own both that workstations. Both likes only ECC simms, they are really hard to find. On 128M you can install
HP/UX 11.11, but it will be very slow. You can even mix EDO and FPM simms in different banks.
B160L has a very strange SCSI. It has 50 PIN interface and 68 PIN, but 68 PIN interface is connected via separated
board and it is HWI (no matter what it means). I was able to connect regular 68 PIN drive to 50 pin interface via
convertor, but not to 68 PIN interface. Also B160L has PCI interface with a hole in the unusual place; I think
that's 3.3V PCI.
No such problems with B180.
Hi-rez photos of boards
Remote dtlogin to HP/UX from Solaris:
Cannot convert string dt-interface system-medium problem
If you have problems loading NetBSD like esiop // siop timeout with lock-up, just plug off the second CPU
If, after you start AIX you see green cursor and then monitor blanks - it means AIX does not like your's PS/2 keyboard, EVEN if ROM code sees it. Change the keyboard!
To go to sort-of-setup, press F1 (or 1 from consle) after it blims. (not beeps; there is a specific sound). To get to OpenFirmware, say F8 (8) (?)
If you try to install windows nt 4.0 ("Multiarch") on this sort of powerPC, find an "arc diskette"
saying here ( local copy )
and plug a PC PCI VGA (that's not a joke!)
to your's RS/6000 (and connect a monitor to it, 640x480 ok). Boot from dikette, CD is not bootable!
BTW, this diskette is VERY strange. Looks like it has x86 emulator - at least it *EXECUTES* *VGA* *BIOS*. I'm shocked!
(well, some HP HPPA computers (C8000) and Itanium also does that by PDC code)
*NEVER* plug an audio jack to the back of Altera based GXT-800P card - you will burn it! (I did). This jack is for some sort of stereo glasses, +12 on it
If you know how to run OS/2 // PPC on RS/6000 7043, especially on 240, TELL ME!
Runs: AIX 5.1L,NT/4.0 with extra VGA card and boot diskette, netbsd 5.1.2 (console on COM0 only) (but not 6.0BETA2??), tries to boot Solaris/PPC from floppy and OS/2 PPC from CD, writes F05 (good!) on operators' LED, writes nothing nor to internal video, nor to PC VGA, not to com0.
What to do if "idprom contents are invalid" ?
1 0 mkp Value idprom address ; to show - address idprom@ .
80 1 mkp For UltraSpcarc II and I and smth else
8 2 mkp Your's
0 3 mkp MAC
20 4 mkp Address
9b 5 mkp
dd 6 mkp
b6 7 mkp
0 8 mkp
0 9 mkp
0 a mkp
0 b mkp
9b c mkp Yours'
dd d mkp hostid
b6 e mkp == lower bytes of MAC
0 f 0 do i idprom@ xor loop f mkp
Next banner. If it does not show "IDPROM invalid" - you're fine
Then set-defaults , then reset
A reminder to myself what I do after fresh installation of Solaris 10 (on Sun blades)
export CFLAGS="-I/usr/local/include/curl"
export LIBCURL_CFLAGS="-I/usr/local/include/curl"
export PKG_CONFIG_PATH="/usr/local/lib/pkgconfig:/opt/local/lib/pkgconfig"
./configure --enable-cli --prefix=/usr/local --disable-nls --disable-mac
Then go to http://127.0.0.1:9091 and enjoy
./configure; make; make install
into /usr/local
