Aha. But why is there no memory test etc? My

It does seem like a customized one. A regular bootstrap

look like:

256 KW
START? _

or such.
If yes, does anyone have a better one?
Depends
on the cards you have. Open up the box, and list
us the cards (the Mxxxx numbers on the board handles will
do), this will tell us the system's configuration.
What to do to get that kdf thing working? How will I
know? On my CPU
board are two eproms with green labels and nothing written on them. The

If it is possible that I don't have the original bootstrap - can anyone
send it to me via email?
Oh, scrap the above :)
You need to carefully inventory your boards and
determine what you
have.
I have:
- CPU (M8189)
M8189 KDF11-BA Q 11/23-PLUS single-board CPU
- RAM (M8067), 128k*18?
M8067-FA MSV11-PF
Q 128-Kbyte MOS memory with parity CSR
M8067-KA MSV11-PK Q 256-kbyte MOS memory with parity CSR
M8067-LA MSV11-PL Q 512-Kbyte MOS memory with parity CSR
- RAM (8059), same size?
M8059-FA MSV11-LF
Q 64-Kword MOS RAM, single voltage
- Floppy controller M8029
M8029 RXV21
Q RX02 floppy disk controller, 18-bit DMA only.
- Emulex SC02/C RK06/07 compatible SMD disk controller
(for my Ampex
hard drive)
- 2 * M8043 (4 serial ports)
M8043 DLVJ1-M
Q 4-Line Asynchronous Interface
- 1 unknown Plessey interface card, P/No. 701775
(What's that ?)
Dunno, sorry.
So, this is an 11/23-PLUS (meaning, 22-bit Qbus), with at least
64+ 2x128KB (probably more, depending on which model of those
two cards), an RX interface, 8 serial ports (plus console),
the hard disk interface, and the Plessey card, which could be
tape, or I/O of some sort.
The system *could* have a non-standard boot ROM on the CPU
board. If so, it will be easy to restore an original in there.
It **could** be the ROM from the Emulex card, by the way, as
the system most likely needed to boot off the Emulex card.
