Doug and everyone... 3.2V? That's seems not right for that ttl cmos family. Should be ~5V +/-5% Keep cranking that power source up bit by bit slowly and monitor the voltage rise or no change? Nearly ALL battery portables use a power supply/charger/power management module and is supposed to be VERY toleranent of WIDE changes in current and voltage ranges between min (battery minium voltage at near discharge end) and max voltage that happens during charging process. These modules vary in all sizes and some notebooks has it all on same board with everything else. Tiniest I have seen so far is in compaq LTE 386s/20 (about 1" x .75" by 2") and largest one I have so far seen is in Epson NB SL/25 notebook. Your pototype looked nearly complete to go into a notebook at get go. So that's means it should have a functioning PSU module part. And nearly all PSU modules use switching technologies. 3.3V based portables started to appear after Intel and AMD introduced their 3.3v chips and chipsets became common after '91 or so. That real appearance takes place about a year after this and totally converted over to all 3.3V logic well after dx4 portables became common. I have a sharp eye for someting amiss. Did you have any few small chips that is stuck with some kind of sticker at all even in socket? This is typical for bios And can you find a CPU somewhere? I think this is 386sx class notebook maybe based on amd or SLC type. Did you have that 32pin SOJ socket empty? That is might be the socket for that bios oh, what a big bummer! And you do have a heard drive made by Areal, long since dead HD maker. Jason D. email: jpero(a)cgo.wave.ca Pero, Jason D.

Doug, Ditch that thing, these warts with switches can't carry more than few mA's for serious work and they're junk anyway. For decent DIY homemade adjustable basic power supply by a pot to a voltage LM317 regulator (with heatsink attached) and few large caps attached to a rectified DC rated about 1~1.5 Amps 24VAC transformer. Should not cost more than $40 and many electronic supplier and component stores should carry a electronic kit that you can build yourself instead of this piecemeal one. Another circuit added to this basic using another LM317 in current mode limiting level fixed by a pot. Look into your local phone book and find a store that is a walk in store that allows you to browse at electronic components and carry tools (many should carry decent tools if found) and lot of kit stuff to put together. For wall warts, I use fixed DC types only for few things as I don't like the swtichable types as I had them die one too many before. And kit form power supplies are much better than this wart crap. Oh, there are several types of LM317's with different max current ratings: 500mA, 1A, 1.5A and 3A, up. That one is not it. that's lamp inverter PSU to light both fluorcsencent and some to power the LCD for operation. That LCD will not come alive without bios as video is under control by that one bios. Often that chip is combined with system bios and the video bios in one chip. Look for naked transformers or three with lot of small power transistors and few big caps around it is your real power module and these are very close to that power input jack. Fair chance that you have a mixed 5V and 3.3V chips. This is 3.3V chip and real dog even at 25mhz with 1K L1 cache on, it's on par with cached 386dx 25. I have one on a cheapo 486SLCe 5V 33 version. No better than a slow cached 386dx 33. Real IBM 486SLC2/50 blew everything away even 486sx2 40! That's in a 700C. Taking a bow at this praise. :) Btw pix does matter. Well, supposed to find a 32pin SOJ small profile retangular chip that could be a bios or a flash chip usually iwth a sticker over it. For short term, ID who's who video chipsets by that logo make and the motherboard chipsets as well as their numbers off them and try to boot with a subbed bios and see how it go in very basic operation? I can't afford or own stock I'm still on "welfare". :( That will change after I get real and get done with education, land a good job. About that hd, I'm not kidding, I have a dead Areal MD2060 too and this is just stock 60mb 44pin IDE out of a 386sx 20 small laptop, and you can change that hd for anything (used or new) up to 8gig with driver software if that bios works. :) I had the 386 owner replace that hd as it was making new bad sectors every time I scan that hd for a NOS 200mb seagate G series about couple of years ago at good price from a known reseller out of computer shopper.
