Partial answer: The file called EXPLAIN
on the floppy disk images contains Danish text with { = æ, | = ø, and } = å. Running it through Google Translate, and touching up the result, gives:
The purpose of this text is to explain how the software Memac,
Frederikshavn Shipyard 421-424, hangs together, and how to make a new tape.
Memac software includes three tapes:
Program Tape:
With yellow labels, made from MEMAC.OBJ.OBJECT on disk or MEMAC/OBJ on
floppy. To start Memac up, put this tape to the machine first.
The tape is marked with two yellow labels. On the top one is written PROGRAM
TAPE, on the bottom one MEMAC 870814.
Data Tape:
With red labels, containing the data that can be changed aboard ship or in
the yard. We save 2 tapes with the latest - as far as possible - version of Anna,
and also two tapes from HPL.
Also keep a printout the content of Anna, as well as of HPL.
New tapes are made as follows:
First record on both sides a little initializing program,
MEMACSUP.DATAINIT.OBJ.OBJECT on disk or DATAINI/OBJ on floppy.
Then record on a 256 kbyte IP2-110 with Tandberg TDV 2220 on
port J5, Config Tape (see below). In the main menu, select '6' - System
Functions. In the submenu select '1' - Get Data From Tape. Insert a
existing Data Tape and press 'G' - thus obtained a RAM copy.
Data can now be stored on the new tape using the '2' - Store Data On
Tape. Repeat the operation on the other side. Verify then with '3'
on both sides. By mistake, boxes tape. Screen says TAPE
OPERATION DONE when all OK.
The tape is marked with two red labels. On the top one ist written DATA TAPE,
on the bottom one MEMAC 870810.
Config Tape:
with green tags, contains the program that is used to correct
the Data Tape. New tapes are made from MEMACONF.OBJ.OBJECT on disk or
CONFIG/OBJ on floppy.
The tape is marked with two green labels. On the top one it
says CONFIG TAPE, on the lower MEMAC 870401.
These disks are available in a version for Anna and a version for HPL.
All the /OBJ
files are in Standard Object Code Format as described in the Model 990 Computer Assembly Language Programmer's Guide, pp. 10-17 ff. That means you don't need to compile them, and in principle you must just copy them to tape, using whatever utilities your OS provides for this.
I still don't know what type of OS or what type of tapes you use. The Tandverg TDV 2220 is a video terminal, but I can't see any tape drive on the picture, so that's probably addition hardware. I can't find any information on what type of tape
IP2-110 is (if it's a kind of tape), either.
I tried running or linking MEMAC/OBJ
on the simplest system provided for the simulator on Dave Pitt's page, the asr733sys.fpy
image, but it doesn't load, probably because the I
tags at the end are not understood.
So to try this out on the simulator, I need to have some idea about what OS it is for.
SDSLNK
linker for the Ti-990. The utilities include a program to make a tape image file, so the logical format of the tapes is known.
