I just picked up this point-of-sale PC cheaply (less than £30 including shipping). It's labelled as a 'DigiPOS Pro' with the following spec:
IDT Winchip C6 200MHz
Custom ALI Alladin 3 motherboard
16MB RAM (2x 72pin SIMM sockets with EDO support)
4.3GB Seagate IDE drive
Onboard CL-7548 (no mistake - it's the mobile chip; feature wise it looks like somewhere between the 5428 ISA/VLB and the 5434 PCI series)
4x 9pin serial
3x ISA + 2x PCI (1 shared, 3 slots total useable*)
It was sold as not powering on, but it was quite clear straight away that it was a memory fault, and removing the supplied 16MB module and fitting two known-good 32MB EDO sticks got it powering on with all 64MB detected correctly.
Floppy drive isn't detected, and the IDE drive is missing from the detection also. The onboard RTC module (Award labelled, but likely a Dallas underneath) is clearly long dead.
It's a weird little design - very compact; the motherboard is tiny, but with a pair of horrendously noisy 50mm fans (one blowing over an enormous aluminium heatpipe/heatsink similar to what you would find on a laptop) that I will have to replace with something a bit quieter. The entire 'guts' of the machine slides out of the rear of the case, making replacement of the parts much easier than disasambling things piece-by-piece to get to the motherboard.
* One issue is the length of the ISA/PCI cards that can be fitted - the heatsink arrangement means that two of the possible three ISA cards can't be much longer than a 16bit slot - so no AWE32's for this thing. The two PCI slots would take cards up to 9" / 24cm.
Where was I? Ah yes, the motherboard!.
I had forgotten just how bad some motherboard designs were in terms of manual configuration. This thing has around 30 jumper blocks and two sets of dip switches. There is no silkscreen available which describes their purpose!
If I can get the floppy and hard drive replaced (I usually use a bay-mounted CF adapter, but that's out of the question as the front panel only has a 3.5" slot) and bodge the RTC with a coin cell, then this could make a nice little high-end DOS gaming machine. I will need to find some more info on the motherboard however, as I've no idea what voltages it supports, nor what processors.
Anyone else tried one of these terminals?
