Stunned at the price of a book...

[TheMonkey]

Hey! I wonder if the other Babani books are worth that much. Not done electronics for yonks but still got them all tucked away in the shed.

PS That was a bit silly mentioning the price. If one of us had got it I daresay we WOULD have given you a worthless old book for the cost of the postage.

Yeah I doubt anyone has it though. It's the only Babani book that is worth something as us elitist synthesizer builders like to collect texts on building synth modules ... because we're sad.

You can't possibly be as sad as me ; collecting old & obsolete video cassette recorders...

And I'm not as sad as the Septics who collect old & obsolete broadcast Video Tape Recorders, seriously big & heavy iron that...

Loved the statement on one site "had to saw the chassis in half to get it down into the basement". (Machine weighs about 1300lbs ).

R.A.Penfold Books - Have you tried you local branch of Maplin?

Are you sure I ca'nt interest you in Babani's "Building Your Own Solid State Oscilloscope" for a mere fifty quid? I am sure synthesizers and oscilloscopes are basically pretty similar.

They are much cheaper here

Feck me, I'm getting old, I only just got that...

I might be able to top that in sadness. I have a pile of 12 dead circa 1990 Sun workstations in the kitchen, a big and dead 8 processor Sun 1000E and a dead BBC Doomsday setup on which the LaserDisc player is dead.

It's an "obsolete" book and Maplin have a policy of throwing old stuff out. I've even tried Babani who were actually rude and unhelpful (they're getting old now).

Very funny. I have a nice Philips scope here. Well not nice, it's a beaten to death ex-MoD bag of tulipe but it cost £10 and works well enough.

I surrender; you are sadder than I...

That BBC Doomsday thingy is an appreciating asset if you could get the LaserDisc player to work...

I wish I could get it to work so I could sell it (seem to hit the £2-5k mark on ebay complete!). Unfortunately the SCSI controller in the LaserDisc is completely dead and it appears to use some completely non-standard ASICs on it for which I can't even find a reference to, let alone an alternative. I've had my eye on ebay for 2 years but have been outbid on nearly all other broken laserdiscs.

Ironically this thread inspired me to fire up the 1000E for a last go and I got a console on one of the serial ports. Might play with it today and see if I can get Solaris on it.

Probly some manufacturer's in-house code... any idea who made the ASICs?

And who made the LaserDisk player?

Can't be many options, the ones who spring to mind are Philips and I think Sharp, though that might be a load of bollow.

It's a Philips one. The main problem is that the SCSI interface wasn't present on standard "video grade" players - only special ones.

The chip is a 40 pin DIP package which is possibly a ULA part (same as Sinclair core chipset but it's (c) philips) so it probably could be reverse engineered quite easily but I don't have the time or knowledge to do so. I know it's that that is screwed as the power rails are closed circuit when the chip is present (causing the PSU to clamp) and open when it's out.
