FOR IMMEDIATE RELEASE
STonehenge
Atari ST Memory Expansion Alternative.
A solid state disk drive for the Atari ST is now available
as a kit from RONSAT Technologies Inc. The STonehenge
kit, based on an "Application Specific Integrated Circuit"
(ASIC), emulates a hard disk by interfacing the ST's DMA
port with a block of DRAM.
The STonehenge advantages over internal memory expansion
include; ability to utilize lower cost 200 nano second
DRAM parts; memory expansion in 256KB increments (8
DRAMs/bank); does not depend on the ST's power supply;
it's external, you don't take your ST apart; data is
preserved even though a ST power cycle.
When the kit is fully assembled it provides up to 2 meg of
very fast external storage. If you need more that 2 meg,
the DMA pass thru feature can be utilized to dasiy chain
more kits or mechanical hard drives.
Software developers will find that STonehenge's speed and
after crash data integrity make it a very attractive place
to keep their development tools. Animators will enjoy
STonehenge's ability to sequence image files at animation
rates.
The STonehenge kit priced at $169.95 includes;
a. STonehenge ASIC,
b. Double sided PCB,
c. 20MHZ crystal,
d. DB-19 connector,
e. Documentation,
f. Software,
g. PGA socket for the ASIC.
The Documentation and Software can be ordered separately
for $10.00 (refundable with future purchase).
The builder of the kit must provide the DRAMs, a 5V 2A
power supply, and a few miscellaneous components that are
readily available from electronic suppliers.
Additional support kits that provide all the components
are also available.

[ line eater munchies ] DRAM is added 8 chips at a time...which means no parity protection. The product sounds fine except for this omission. Is it too late to fix? -- Mark C. Edwards voice: 619/586-2204 Associate Systems Analyst unix: mce@pbsdts.pacbell.com

Is it too late to fix? I would prefer to say that it is to late to enhance! however the clever never say never. The silicon and the PCB are final versions, but I would guess that an add on is possible. The docs include a schemo, so hack if you dare. -- Ron Schreiner AT&T Bell Labs ...ihnp4!ihuxy!rnss

Is it too late to fix? DRAM is definitely NOT added to the ST 8 chips at a time. Due to the 16-bit memory bus on the 68000, the chips are added *16* at a time. You are correct in stating that the ST does not use parity-checked RAM, but on systems like the IBM PC, the parity bit really doesn't gain you anything. -- "The whole problem with the world is that fools and fanatics are always so certain of themselves, but wiser people so full of doubts." - Bertrand Russell "How come he didn't put `I think' at the end of it?" - James P.

Due to the Right, DRAM is NOT added to the ST 8 chips at a time, but it is added to the STonehenge RAM Drive 8 chips at a time. -- Ron Schreiner AT&T Bell Labs ...att!ihuxy!rnss
