I have always wanted a Cadillac.
Hi, I have acquired an IBM PS/1 multimedia.desktop computer.
I think this was the first Multimedia computer built by IBM for the home consumer market.
This would have been the pre-built 486 computer I would have liked to have back in 1994.
My 1993 custom 486 mid-tower build was almost this nice.
These IBM PS/1 computers with there IBM software interface menu are the Cadillacs of the 486
Computers for there time.
Made in U.K.
Build date Jan 17, 1994.
It came with a Sound Blaster 16 CT1740 with Yamaha OPL3 and CDROM IDE interface.
A combo 1.44/5.25 floppy drive
And Panasonic CDROM ( IDE )
Motherboard has 5-ISA slots on a riser board.
Onboard Cirrus logic GL-5428 graphics.
So I wish to restore it.
It did not come with a hard-drive
I think these came with a Western digital hard-drive for IBM.
If not I plan on using a WD drive because they are inexpensive and available.
The IBM drives are rare and expensive and hard to find a good quiet one.
The WD drives are quiet too.
I know some newer 486 IBM computers used WD drives.
Also I want to upgrade the cache to 256kb because it only has 8kb onboard right now.
All the cache slots ( 8 ) are empty and the tag slot is empty too.
Can I use any type of cache or do I need a specific brand ?
Right now I have -15 and -20 cache 256.
Right now it has 20mb of ram. 4 ram slots.
I want to max this out.
What is the max ram config I can use ?
I only have two ram sticks right now.
It currently has an Intel 486 DX2-50 CPU.
I have an Intel Overdrive CPU DX4-100, Should I install it ?
I have a 2mb Cirrus Logic GL-5429 video card. Should I use it or is the GL-5428 1mb. good enough.
It has a modem. Not sure what speed but it is a conaxent model.
I have a 3com 3c509b Combo Ethernet IIi ISA card I can use or should I use and Intel or IBM network card ?
Question: Restore to original specs or Max out the motherboard ?
Use only IBM parts or is IBM compatible okay ?
