MEMORANDUM FOR: Distribution
SUBJECT Disposition of IBM System 360/30
1. An IBM 360/30 Computer under rental by OCS has been
used for the past several months
This computer 1s e g uae
to check out the programs and the hardware interface associa e
with the analog-to?di ital converter (ANDI) they will deliver to OCS
under contract
2. The ANDI will be delivered approximately 10 September
1966 and will be connected to an IBM 360 Computer already installed

in the Computer Center. The computer at will not 25X1 A
be needed after that time. Unless an Agency requiremen or sub-
sequent uae of this computer is identified, we will direct it to be
released and returned.
3. Your suggestions of possible follow-on use of this computer
by the Agency at Headquarters or other sites are solicited. It should
be noted that the OCS FY-67 budget only provides for the rental of
this computer through August 1966. Attached is a short description of
this machine which includes size, rental cost, and limitations.

two selector channels, storage protection
Typewriter Keyboard Terminal
1 Line Printer (600 lines. per minute)

Software
The above IBM 360/30 with 65 K bytes of core cannot be
expanded, and the core limitation does present some limitations
on software:
a. Operating System (OS)

(1) FORTRAN-E is available. This is a subset of
FORTRAN-H and of IBM 7090 FORTRAN and thus there
are serious limitations in running FORTRAN programs
written for another machine. FORTRAN-E is satisfactory
for simple to medium complex programming. However,
object programs are necessarily quite limited in size.
(2) COBOL-E. Runs well and is adequate.
(3) ALC-E. Runs but is slow.
(4) PL/1-F'. Runs well.
b. Basic Operating System (BOS)
The above languages are available under BOS, but some in-
compatibility exists with OS. However. the Mod 30 is quite adequate
using BOS and will furnish a versatile, but somewhat slow in size and
speed, capability.
