I'm considering attending this Amiga 40th anniversary celebration. I was invited to speak on a panel on the topic of the experience of early Amiga code development. Who else might attend? - John

EPSON 6110 Tape Punch Interface

by Martin Bishop

I have a salvaged Epson 6110 tape punch on the bench, also it's interface card from a Data Dynamics Zip 30. The 6110 is the shiny paper tape punch which was very common, at front left, on TTY etc in the 70's and into the 80's I'm working on reverse engineering the Epson 6110's connector / interface, it's a "centronics" 24 pin. Does anyone have or know of a spec for the Epson interface, or manuals for a system using it. The basics are plain enough 24V power, ground connections, 8b+s, all low side drivers (54SN463's), one output (to a 7414) I presume Ready_n, and another two inputs I guess Enable_n and Advance_n (or maybe Reverse). RevEng should get me there, documentation would ensure no possibility of magic smoke - excluding bad components. Bring up plan is: - apply 28 V and scope "connector" - button up to suitable processor; ie interpose LoSide drivers between processor's LVTTL and the punch VMTiA Martin

DEC VT11/VR17, BA350/BA356, "S" box boards

by Paul Anderson

Just a quick note/ update from my earlier post. If you're looking for an option, please send me the board #. Example:A DLV11 can be a M8017, M8027, M8028, or M8043 if my memory is working tonight. My boards are basically in numeric order, and it takes time to convert option # to part # and I don't want to ship anyone the wrong part. I have a few VT11's I will finally sell, along with a (believe it or not, long story...) VR17 which now has screen rot. A few dozen BA350 and BA356 boxes and selection of power supplies and drives. 50 or so "S" box handle boards including M3108, M3116, M3127 DESQA, M3134, M5976 KZQSA, M7493, M7740 KLESI, M8086 LPV11, M8020 DPV11, M7516 DELQA, M7504 DEQNA, M7504, M7554 CPU, Non DEC and more. Also found a pile of DECMUXII , DECMUX300, decservers and that type of stuff. And something everyone needs, SC08s!!! Please excuse any typos or messed up part #s. Thanks, Paul

Looking for IBM System/3 BASIC book

by Steve Lewis

Per the link below, it mentions a reference manual to IBM's BASIC for the System/3 as part number GC34-0001-1 but that no digital copies are known to exist. https://manx-docs.org/details.php/19,11119 I know at VCF East they've been trying to restore one of these. Not sure if any functional system still exists (especially probably not the Model 6 with CRT and disk drive). Anyway, if anyone happens to have the physical manual described above, I'm just curious if in the first few pages was it publication date? (before or after 1970?) Also - since IBM went out of their way to re-use the BASIC from the System/3, does that imply there was never a variation of BASIC written for the IBM 360/370? (asking because from my understanding, the System/3 was a lot more difficult to program and operate -- and yet someone wrote a BASIC interpreter for it). -Steve
