I agree a very fancy data path/alu chip. <of the 29116s and 32 control lines for bus requests, data transfer <between the 29116's, etc). I have one sitting around... maybe I can do something with it. I have data. Allison

QuantumLink AOL lore...

by foxnhare＠goldrush.com

Actually... Quantum Computer Services started off Quantum Link from the old Commodore 64 Play-Net network and later developed Apple and PC link as those developed (from the old Q-Link system) Quantum Computers changed their name to AOL and later shut down the Commodore Q-Link service after leting it suffer a slow-agonizing demise for a few years. Pitty, it was a good service. There are still a bunch of Q-Link ideosyncracies in the system such as 10 character screen names. There is a web page out there that gives the whole story, I came across it a while back in my surfing. Hopefully Doug Coward will read this and fill us in better, as he was an actual Q-Link employee for many years (read he actually worked there, not a Q-Guide or some sub-op position). -- -+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+- Larry Anderson - Sysop of Silicon Realms BBS (300-2400bd) (209) 754-1363 Visit my Commodore 8-Bit web page at: http://www.goldrush.com/~foxnhare/commodore.html -+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-

Never pass an $8 computer [Apple IIc swapmeet story]

by thomas100＠home.com

Hi, So I bought two Apple IIcs last year, one from at the Capitola Swap Meet for $8 with no power supply and a bad keyboard and the other at a ham radio swap meet for $15 with the cute little monitor, stand, power supply, TV adapter, printer and a bunch of other junk [Printshop and... what a thrill- typing tutor!] I bought the two machines some time apart from each other and was moving about the time I picked up the second. So finally today I found that the first one work while the complete system I bought is broken. Well... it's no problem since I can make one working model out of two. Fortunately the first one also has a case with no yellowing problem. The moral of the story: Never pass up a $8 retro-computer... even if it's broken and incomplete! Thomas

RL02 ID number button

Just unloaded the 11/24 from the car and did take the number plugs out. If the only problem is the edge, then applying a drop of 2 component epoxy glue and file the excess away after hardening should then do the trick, would is not?

XEROX 860 IPS

by cad＠gamewood.net

Hi Folks: I was donated a XEROX 860 IPS. Portrait oriented Hi-Res display, 2 8" floppies. Keyboard with a circular 'touch pad' on the right end (of the keyboard) The Problem? I was just getting to the point of trying to 'backup' the software (disks), and look around in the system, and the 12v portion of the power supply died. No 12v, no boot. Anyone have any schematics for the power supply?

As for the F-11, hadn't I just agreed with Tony that a chipset like the F-11 was a microprocessor? Philip.

<Yes, I agree with that one. Slight grey area here - things like the <floating point unit in the LSI11 or the CIS in the KDF-11 - are they <part of the microprocessor chipset or are they coprocessors? Depends, For the KD11 it's additional microcode. For the KDF-11 it's either more microcode(EIS/FIS chips) or a FPU (FPP-11 board). <> Byt that definition, anything built out of TTL, 2900 series, 3000 serie <> etc is _not_ a microprocessor. Those chips have uses other than for What about the 29116? It falls right on the cusp I'd say. <So I notice. But by that definition _none_ of the micro PDPs were true <microprocessors, or at least none up until the 73. The Micro J-11 <processor in the 73 was implemented as two chips on a large ceramic <carrier. Was this also the case with later J-11s? Unknown here. You forget the T-11 which was a single die and a single 40 pin chip that was used on the KXT-11 series boards (falcon etal). Allison
